This needs to be installed this way because the Flange Yoke will not go through the Crankshaft access hole in the front of the Tractor (See Figure 3). Bolt the Flange Yoke to the Pulley Adapter using the four 7/16" X 1-1/4" Bolts (Part # 02976344), use the four Lock Washers (Part # 00022200), put Locktite on the threads of the Bolts and install them into Pulley Adapter. To Tighten these four Bolts, use a long extension and go through the front Crankshaft Pulley access hole in front of Tractor. Do Not use bolts longer than 1-1/4" long, longer bolts will damage Crankshaft Pulley.

Insert the 4 bolts and lock washers into Pump Mount Plate and spacers (See Figure 7), tighten them to required Torque (See Bolt Torque Chart). 2. Driveline timeing means the universal joints are both the same position when driveline half is slid together. If they are not timed, it will decrease the life of the universal joint and in some cases could cause a vibration. (See Figure 5 on previous page) Tractor Engine Left Hand front side of Tractor Spacer (2) Figure 7 Standard Pump Mount Plate Shown Tube End of Driveshaft 3. Install Tube End of Driveline / Pump End. Slide the Tube half of driveshaft through Pump Mount Plate and Tractor Crankshaft Access Hole (See Figure 8). You will have to align the Universals when doing this (time the Driveshaft). Slide the two together where the Universal are in time (See Figure 5 on previous page), this will help the driveshaft to operate smoothly.

Section 3 - 4 Standard Pump Mount Plate Shown Pump / Drive Assembly Instructions Installing Pump Mount Plate & Tube End of Driveshaft: (continued) 4. Loosen Splined Clamp Yoke. Insert a bar through the Yoke to hold Driveshaft up and to help loosen the Bolts in the clamp Yoke (See Figure 10). This can be loosened with a hand Wrench or a Socket whichever is easier for you (See Figure 10). Some times it is easier to test fit the Tube End of Driveshaft to the Pump while the Pump is on the bench. Bar to Hold Drive Shaft Installing Pump: Driveshaft, Spline Clamp Yoke End 1. Install Pump into Splined Clamp Yoke. Slide the Pump Splined Shaft into the Spline Clamp Yoke (See Figure 11). Leave the Bar stuck in through the Yoke as shown, this helps to stabilize the Yoke as you slide Shaft into the Yoke. Once Pump is slid into the Splined Yoke, keep the Pump supported; DO NOT let the Pump hang on the Yoke unsupported. Figure 9 Bar to Hold Driveshaft 2. Pump / Driveshaft Yoke Gap Adjustment. After sliding Pump Shaft into Splined Clamp Yoke, the Pump and Yoke must be slid apart far enough to allow for a 1/16" to 1/8" Gap between them. The Yoke edge cannot touch the Pump Housing; it will damage the Housing and the Yoke if it does. This is a very critical adjustment (See Figure 12). Loosen Clamp Yoke Bolt 3. Tighten Clamp Yoke. After Gap between Yoke and Pump has been adjusted tighten the Bolts & Nuts on the Clamp Yoke (See Figure 12 & 13). Check Pump to Yoke Gap once more. Keep Pump Supported do not let it hang on Yoke.

Mount Pump to Pump Plate. Remove the Bar that is slid through the Driveshaft Yoke and push the Pump inward (See Figure 14). This will make the two piece Driveshaft slide together allowing the Pump to be pushed towards the tractor. Do this untill the Pump is against the Pump Plate (See Figure 15). 6. Install Pump Mounting Bolts. While holding in on the Pump (See Figure 15) start the two Pump Retaining Bolts. Make sure both Bolts are started well before you stop supporting pump. The Bolts should be snugged untill pump sits level before you stop supporting it (See Figure 16). Let go of the Pump, it may slide back some and leave a slight gap between Pump and Mounting Plate (See Figure 16). Figure 13 Gap ? Check, this must have a gap between Pump & drivesahft 7. Tightening Pump Mounting Bolts. There is a shoulder on Pump Flange that must line up through hole in Pump Mounting Plate (See Figure 14), if the Pump is slid back as in figure 14 try to push it inward untill it is against Pump Mount Plate as shown (See Figure 15). Slowly and alternating from Left to the Right side, tighten the Pump mounting bolts untill they are tight. DO NOT FORCE Pump through Pump Mount Plate, if it will not freely slide in check for a problem of some kind. Excess force could damage Pump Housing. (See Figure 16). Do Not remove any Plastic caps from Pump inlet or outlet at this time, keep all openings plugged and sealed to keep them clean.

Find the front most 4 Bolts in the Tractor Frame Rail, There are 4 on the RH side and 4 on the LH Side. DO NOT REMOVE THE BOLTS FROM BOTH SIDES AT THE SAME TIME, ONLY do one side at a time the RH or the LH. For illustration start with the RH Side (See Figure 17). The RH & LH Frame Rail Supports have a Right and a Left. They will not interchange and must be mounted on the correct side. Notice the way they are built, the Plate part that bolts to Tractor is longer in the front on both LH & RH. Make sure the longest part is to the front (See Figure 18). 2. Install Frame Rail Support RH Side. This works best with a 2 man team. The RH Frame Rail Support the is held on with the 5 bolts that Bolts that are supplied w/ mounting kit. Start all 5 bolts with Lockwasher before any of the 4 are tightened (See Figure 18). When tightened down it will look like the picture in Figure 18. Tighten the four retaining bolts for the RH Frame Rail Support before lossening or removeing the bolts on the LH side. Figure 17 Right Hand Frame rail Support Shown 3. Install Frame Rail Support LH Side. Make sure that the bolts on the RH side have been tightened before removing the four bolts on the LH side. The LH Frame Rail Support will install the same as the RH side did. Remove the 4 bolts; Install the Front Frame Rail Support. Tighten the 4 bolts through Tractor Frame Rail. (See Figure 19).

Section 4 - 1 Frame Rail Set Up Frame Rail Pre-Assembly: The Frame Rail Set UP. The Frame Rails for the Machete will be set up on the tractor, positioned, measured but not welded. The Machete High frame is set on to Frame Rails, positioned and leveled. After all is set up and positioned it will be Tack Welded in Place on Tractor. Then it will be dis-assembled and welded up on the Shop floor. This is done to ensure better welds and to enable the parts to be turned so the components can be Flat Welded. It has been found that this will make the components stronger. This also gives a chance for all frame components to be test fitted and broken loose during this trial if when another component makes the previous one interferes. The Tractor should be covered and protected from Spark from the Welder and Grinder at all times. It will be your responsibility to protect the Tractor and its components. DO NOT WELD or GRIND near any Glass or Painted Surface unless it is protected from sparks, these Sparks will damage any surface. The purpose for Setting Frame up, tack welding it then removing it, is because with the amount of Welding that will have to be done these frame components will need to be repainted. The repainting is easier with frames off. The Frame components are shipped already painted but this is to protect the metal, plan on repainting them after welding. DO NOT weld any frame or component untill instructed to do so in the instructions. Read through this entire instruction book to be familiar with which part goes where and when. DO NOT try to man handle large components alone, one slip can break a window, damage a hood or worse. Note the order of assembly of other Assemblies, example the Pump Drive Shaft, Front Rail Supports, Rear Stack Valve Modifications and Joystick Assembly are assembled to Tractor before the frame rails. This is because some components will be in the way of others after they are assembled.. A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc.

Frame Rail Installation Pre-Installing Frame Rails: 1. Lay Out Components in Display. It is helpful to lay out the component in as neat a display as possible. Lay out the Bolts according to size and length. Lay out the Nuts and washer by size. This will allow you to see how many of each part as you use them and help to identify any missing parts. (See figure 6) 2. Front Frame Rail Supports. These Frame Rail Support Mounts (part # 02979765 LH & 02979766 RH). These should already be mounted from previous Assembly of Front Pump and Drive Shaft Components. It is easier to mount the Pump Drive Shaft before these Frame Supports are installed. If you are mounting the Frame rail supports now, there are important things to remember. There are 4 bolts that go through Tractor Frame that will have to be removed before this can be mounted, DO NOT remove these 4 bolts from both sides (LH & RH) of the Tractor at the same time. Remove the 4 from one side or the other, install the 4 retaining (New Bolts) that hold the Rail Support Weldment on and tighten them. Then go to the other side and remove the 4 Bolts from Tractor Frame Rail and install Machete Frame rail Supports using the 4 new Support Retaining Bolts. The Tank Support brackets connect to the Tractor. These will be mounted when the Frame Rail Supports are installed (See Figure 7). Figure 6 Figure 7 3. Rail Support Gusset Mount. There are two Bolts in the Tractor frame rail that will need to be removed in order to mount this gusset support. It is easier to do now with the frame rails off. It will need to be installed now, as the Frame Stiffener Assembly will line up with these Gussets. Note the angle on the Gusset as it is being mounted (See Figure 8) See Figure 2 for drawing of Frame Stiffener Kit and Part numbers for components. Figure 8 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 4 - 8 Frame Rail Support Brackets Frame Rail Installation Pre-Installing Frame Rails: (continued) 4. Front Rail Mounting Pad. There are two of these Pads; one is used on the left and one on the right. These Pads are the same so it will not matter which goes on which side. (See Figure 9). Set the Pad down over the Front rail Support aligning the four holes in pad with the four holes Support. Insert the four Bolts into the mount pad and plates on front support mount (See Figure 10). Install a nut on one or two of the Bolts but do not tighten them, the Bolts are only installed to prevent the Pad from moving side to side. 5. Locate RH and LH Frame Rail. There are two different frame rails, RH and LH. Start with either one you want, for illustration we started with the RH (See Figure 11). Remember the LH is the one with the Counter Weight Mount Tubes welded onto it, (See Figure 1) Front Rail Mounting Pad P N. 02725900 Figure 9 Front Frame Rail Mount Pad 6. Prepare Tractor Axle Housing. First look up under Tractor at the rear axle where the frame Rails mount you will see holes in the Axle castings on both LH and RH side that has plastic plugs in them. The Plastic Plugs will have to be removed now as they cannot be removed once the Frame Rails are in place (See Figure 12). Figure 11 Front Frame Rail Support Mount Figure 10 Figure 12 A-Boom(JD 6615/ 7615 Asy Instruction Manual) 07/03 Section 4 - 9 © 2003 Alamo Group Inc. Frame Rail Installation Pre-Installing Frame Rails: (continued) 7. Installing Frame Rails. Using a Hoist, lift the frame rail and slide it into place under the right rear Axle. Hold the frame rails as shown to prevent it from moving (See Figure 13). Using a Floor Jack (See Figure 14) support the Frame Rail up under the Axle. Note: the RH and LH Frame rail will install the same so you can work either side first. 8. Install first Frame Rail to Tractor & Rear Axle. The Frame Rails Mount to the rear Axle of Tractor. The RH Side has Longer Bolts than the LH Side does. This is because the Axle Mounted Boom Rest will also mount here using some of the same Bolts. For now use shorter Bolts to hold Frame Rail up to Axle while you finish the Pre-Installation. The Bolts that were removed from the Tractor when you mounted the Front Frame Rail Supports will work well for this (See Figure 15). Use Extreme caution so that Frame Rail will not hit Cab or Hood & cause damage Figure 13 9. Install the other Frame Rail. The other frame rail will install the same as the first did. DO NOT do any welding at this time. 10. Frame Stabilizer Kit. Locate the Frame Stabilizer Kit (See Figure 16). This should be bolted together as shown, for fitting under tractor and to Frame rails it must be bolted together. Figure Figure14 7 Rear Axle Mount Figure 15 Figure 16 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 4 - 10 Floor Jack and Frame Rail Frame Rail Installation Pre-Installing Frame Rails: (continued) 11. Raising Frame Stabilizer Kit Up Under Tractor. Using a Floor Jack slide Stabilizer Kit under Tractor right behind the front wheels. (See Figure 17). Note the Floor Jack used here has had channel built for it that cradles the square shape, this is also good for supporting the frame rails during assembly. Using Jack helps to align Stabilizer to frame rails. This is shown on a 2 WD Tractor for illustration and is the same for the 4 WD 12. Align Stabilizer Kit. Raise Stabilizer Kit with the Floor Jack up untill it is flush up against the Stabilizer Gusset Support that should already be bolted to the frame from earlier installation steps (See Figure 18). This should be this way on the RH and LH side. DO NOT Weld Gusset to Stabilizer yet this will be done later. Secure the Stabilizer kit to the Frame Rails with C-Clamps on both LH and RH (See Figure 19). You may leave the Floor Jack or remove it. Figure 17 Machete Frame Rail Stabilizer Gusset 13. Align Frame Rails on Front Mount Pads. Locate the Front Frame rails on the mount pad so that there is room for the Bolt heads to clear the Frame Rail. Here we have wedged a Screwdriver with a 1/4" shank between the Bolt Head and the Frame Rail. Anything about that size can be used to keep enough distance so bolt can be removed and reinstalled without interference. Use a CClamp to hold it in place when aligned. Do this on Both the RH and LH side. (See Figure. 20) C-Clamps Stabilizer up against Gusset Stabilizer Kit Figure 18 Frame Rail (Front) Front Rail Mounting Pad Figure 19 Figure 20 A-Boom(JD 6615/ 7615 Asy Instruction Manual) 07/03 Section 4 - 11 © 2003 Alamo Group Inc. C-Clamp 1/4" Shanked Screwdriver Frame Rail Installation Pre-Installing High Frame: 1. High Frame Shipping Pallet. The High frame is shipped bolted to a Pallet, Do not unbolt this from the Pallet untill the Hoist has been connected to the High frame. The Hoist must be supporting the weight of the High Frame before any of the bolts holding High frame to pallet are removed. 2. Prepare High Frame for Lifting. There are two lift lugs welded to the top of the High frame for lifting it (See Figure 21). These Lugs will lift the bare High Frame straight without the King Post Sub-Assembly bolted to it. With the King Post Sub-Assembly bolted to the High Frame it will require you to adjust the length of the lifting chain and lifting point to balance the load (See Figure 22) and lift High frame level. High frame must be level when lifted over Frame rails. Figure 21 3. Level High Frame. Use two magnetic Levels as shown. These magnets should be installed before lifting High frame. The First Magnetic level is put on the Top of the High Frame on the Bottom Side (See Figure 23). This level will allow you to level the frame from left to right without having to climb up later to use a Level that you hold. The Second Magnetic Level is put on the Kin Post Pivot toward the front of the tractor so that it will level the High Frame from front to rear as shown (See Figure 24). Figure 22 Top of High Frame Magnetic Level King Post Pivot Pin Magnetic Level Figure 23 Figure 24 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 4 - 12 Front of Tractor Frame Rail Installation Pre-Installing High Frame: (continued) 4. Lower High frame down over Tractor. This is a two man job in order to keep control of High Frame on both sides of tractor (See Figure 25). Lower the High Frame down over the Frame rails (See Figure 26) slowly, as it must straddle the Frame Rails (See Figure 26). Lower High Frame untill the top of the High Frame is no higher than the cab of The Tractor max. and no lower than 24-1/2" from frame to hood as the min. distance (See Figure 25) . Another mark to look at is the Horizontal tube of the High frame should be parallel up and down with the Frame Rail Tube as shown on next page (See Figure 29). 5. Check High Frame for Level. Check the two Magnetic Levels that you installed earlier. The Top Level should be from side to side of the Tractor (See Figure 27). The level on the King Post Pivot Pin should be level making High Frame Level straight up and Down (See Figure 28). Leave the Magnets on the High frame, as you will have to check then one more time later. DO NOT do any welding at this time. 24-1/2" Min height frame to Hood Figure 25 High Frame Frame Rail 6. Secure High Frame to Frame Rails. Secure the High Frame to the Frame rails with C-Clamps on both sides (See Figure 29). Do not weld anything at this time.

Align High frame to Frame Rails. The High Frame Vertical Tube should be as directly above the Vertical tube of the frame rails as possible (See Figure 30). The illustrations in figure 30 shows the High Frame not directly over the Frame Rail Vertical Tube, try to get it as directly over it as you can. The height of the High frame should be no higher than the Cab of the Tractor.

Notice the washer that is installed between the Angle Mount and Mount Tube, This is there because about a 1/16" Gap is needed between the Mount Tube Plate and the Angle Mount Plate. Putting this 1/8" thick washer on the front Angle Mount end only will allow for this Gap on both ends. (See Figure 33 & 34) This should be done on right hand and left hand side Mounting Tube. This Gap allows the High Frame with the Mounting Tubes welded onto it, to be lowered down between the front and rear Angle Mount, which will be welded to the Frame rails later.

Section 4 - 16 Frame Rail Installation Tack Welding Frame Rails: 1. Tack Weld Frame Rails to Front Mounting Pads. Check to make sure that the Frame rail is still aligned on front rail Mounting Pad, Frame Rail should not interfere with the Mounting Pad bolt heads Check the LH and RH Frame rail (See Figure 35). If alignment is correct Tack Weld the Frame Rails to the Front Rail Mounting Pads. (See Figure 32). When tack Welding use 4 good tack welds per Frame rail, 2 on each side of Tube. (See Figure 37). The C- Clamp on The Frame Rail Tube at the mounting pad can be left on till later. 2. Tack Weld Frame rails to Frame Rail Stiffener. Tack Weld the frame Stiffener Brackets to the Frame Rails, but be sure you DO NOT tack Weld the Stabilizer Gusset at this time (See Figure 38). The reason for not welding the stabilizer gusset at this time is because it would make it more difficult for you when you remove the High Frame and Frame rails for final welding. The Tube Crossmember of the Frame Stabilizer can be removed now. Remove the four mounting bolts and slide the Tube forward or back to get it out. (See Figure 39).

The Angle Mounts should be tack Welded to the Frame Rails in 4 places each. This works best by weld a tack Weld in each corner of Angle Mount. (See Figure 40 & 41). All 4 of the Angle Mounts must be Tack Welded to frame rail now. Tack Weld in 4 Corners of Angle Mounts 7. Tack Weld Mounting Tubes to High Frame. The Mounting tubes will be Tack Welded to the High Frame in 3 places on top and 3 places on the bottom, on both LH & RH Side (See Figure 42 & 43). These Tack Welds need to be done in an alternating pattern so Mounting Tubes do not Lift or move. There should not be any gaps between Frame Rails, High Frame or Mounting Tubes.

The RH Front bar Mounting Straps will have to be cut (See Figure 31) and welded to the top of the Mounting Tube (See Figure 43). Another one cut off and welded to the Bottom of the Frame Rail. (See Figure 45) The length of these Bar mounting straps should be cut so it will not be sticking over past frame rail. These can be Tack Welded while still mounted on Tractor, Illustrations are shown with frame rails off of Tractor because it is easier to see and it can be done after they are removed from tractor if you want. These must be Tack welded in alignment when installed, so the holes are in line. If not in line the Bolt cannot be installed. Measure the distance from the Angle Mounting to the Mounting Bar that you have welded to the mounting Tube. (See Figure 43). Transfer that measurement to the bottom of the Frame Rail and Tack Weld a cut off Bar Mounting Strap there. (See Figure 44). Figure 44 shows a top (Un-Cut) Mounting Bar being held down with a C-Clamp, this is done to make it easier to transfer measurement to lower Bar Mounting Strap.

Section 4 - 20 Lower Bar Mounting Strap (Cut Off) Frame Rail Installation Remove High Frame for Final Welding.: 1. Remove and Weld High Frame. Lift the High frame back up off of frame rails (See Figure 46). Finish Weld Mount Tubes. The Mounting Tubes are to be welded completely all the way around. This is why it is best to take High frame off, so that the Weld can done as strong as possible and in places that you can’t get to with High frame mounted on Frame rails. This is also recommended so Assemblies can be turned while welding to get maximum quality welds. 2. Welding Mounting Tubes all the way around. The Mounting Tubes must be welded to the High Frame all the way around, Turn High frame as required to weld all the way around (See Figure 49 & 50). These must be strong Welds.

It is best to remove the Frame Rails to weld them. Frame Rails will need to be welded in five places. Note: The RH Frame Rail and the LH Frame Rail will have the same Welding done. For Illustration we are showing the RH Frame Rail, but the LH will have to be done also. Do Not Weld next to Bolt Holes, it will interfere Hex Heads of Bolts 2 2. Weld Front Mount Plate. Weld down each side between Bolt Holes. Do not Weld to where the Weld will interfere with the Hex Head of Bolts when they are installed. Also weld across the Front of the Mounting Pad. (See Figure 51, 55 & 56) 3. Weld Front Angle Mount. Weld the Front Angle Mount to the Frame Rail on the Sides running parallel to the Frame Rail, Not across Frame Rail (See Figure 52 & 58). Weld the Rear Angle Mount to Frame rail the same as the front (See Figure 53). Figure 51 Weld along sides of Angle Mount and frame rail on both sides (this applies to"A" & "B") 4. Bar Mounting Strap. Weld these all the way around, first check your measurements for placement. The Bar Mounting Straps are cut and must be placed to where they will line up with the ones that you welded to the High frame mounting tubes earlier. (See Figure 53) 3 5. Frame Rail Stiffener Weldment. Weld the Frame stiffener to Frame rail on both sides. (See Figure 24). Touch up or re-paint frame components after welding is completed. There are other components that need to be installed before you reinstall frame. Figure 52 3 5 4 Figure 54 Figure 53 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 4 - 22 Frame Rail Installation Remove High Frame for Welding.: (Continued) 6. The Side Rails. These Frame rails will be welded to the Rail Support Plates, so it will be necessary to scrape the paint off approximately 5/8" of the base before attaching. Clamp Side Rails to Front Mount Supports. (See Figure 55). Tack-weld rails to Front Mount Brackets. After thorough check for horizontal and parallel location, weld a solid 1/4" fillet weld bead 8" long on both sides. (See Figure 56). Note that any Step Type Counter Weight must clear the Left Rear Tire. NOTE: There is a Tire Limit, This should be addressed when ordering the Mount Kit designed to fit with the specified Tire Size. If larger than Tires specified for Mount Kit are installed, mounting kit may not fit. Figure 55 7. The Pig Tail Brackets will be welded to the underside of the Rails, so it will be necessary to scrape the paint off from this area before attaching and welding them (See Figure 57). These Pigtails are to hold the Hoses up. Be sure to run the hoses for the Boom through these Pigtail rings. NOTE: All parts are painted. When welding is required, scrape away the paint in the area to be welded to help assure the integrity of the weld. Repaint / Touch-up welded parts after finished welding. Pigtail Bracket 1/4" Figure 56 Weld here on both sides. Do not weld Across the Tube. 3 Figure 57 Figure 58 A-Boom(JD 6615/ 7615 Asy Instruction Manual) 07/03 Section 4 - 23 © 2003 Alamo Group Inc.

Section 5- 1 Frame Rail Installation Re-Install Frame Rails to Tractor: 1. Re-Install Frame Rails. With the Welding done touch up or re-paint frame rails before reinstalling them. The RH and the LH Rail will install to the Tractor the same except for the Boom rest that installs on the RH Rail Rear Mount. It is best to do the Left Hand Frame Rail first then the RH Rail. Use a Hoist to install Frame rails to Tractor. (See Figure 1). 2. Install the Bolts into the rear Axle Housing to support the rear of the frame rails. This is the same for LH & RH. Snug the Bolts only. Do not tighten them yet because the frame rails will have to be moved around to align all the Bolt Holes. (See Figure 56). The RH rear Frame Rail Mounting will need the Bolts removed to install the Axle Mounted Boom Rest (See figure 5, 6 & 7). Frame Rail Mounting Figure 1 Mounting to Rear Axle 3. Install the Bolts into the front mounting Plates on the LH and RH Side. Snug them only. (See Figure 3). 4. Install the LH Axle Straps. The LH Axle Strap can be installed now (See Figure 4). The Left Hand Axle Strap uses two long Bolts with Nuts. The Bolts go down through the Holes in the rear Axle Mounting Plate that is welded to the rear of the frame rail. Once the Rear Axle Strap is installed the Bolts for the LH Frame Rail and Axle Strap, snug the Bolts only, do not tightened them down (See Figure 1, 2, 3 & 4).

Section 5 - 2 Frame Rail Installation Re-Install Frame Rails to Tractor: (continued) 5. Install Axle Mounted Boom Rest. This will require two people, one to align the Boom rest with the Hoist and one to align the Bolt holes on the bottom to start them into the Axle Housing. (See Figure 5, 6 & 7) When the Bolts are installed into the Frame Rail & Boom Rest Plates and snugged up to Axle housing, install the RH Axle Mounting Strap (See Figure 8, 9 & 10). Do not tighten Bolts snug them only for now.

This will consist of a Tube cross member and four Bolts and Nuts (See Figure 11). Install the Bolts with the Nuts on Top and bolts coming in from the Bottom (See Figure 12), this way only the Head of the Bolt is lower than the Crossmember. Snug the Bolts; do not tighten them yet. RH Axle Strap 7. Weld Stabilizer Gusset to Rail Stiffener Weldment. Weld the Gusset to the Stabilizer Weldment now, Weld on both sides of the Gusset. The LH Gusset and RH Gusset must be welded. (See Figure 13). Check that all Bolts and Nuts are installed.

Re-Paint or Touch up Paint on High Frame now before lowering it on to Tractor. Keep in mind there will be one more Place to Weld on High frame that will need touch up Paint later, this will be the Counter Weight Lug that weld to High frame. The Lug for the Counter Weight will be installed later. 2. High Frame Mounting to Tractor. This is a two Person Job to maintain control of High Frame and guide it down over frame rails. (See Figure 14) 3. Align High Frame. The High frame with the Mounting tubes welded to it will sit down over Frame Rails. The welded on Mounting tubes will slide down into the Angle mounts that are welded to the Frame rails. (See Figure 15 & 16). Both sides must go down evenly. 4. Aligning Mounting Holes. The Holes in the Angle Mounts welded to the Frame Rail and the Mounting Tube Plates that are welded to the High Frame must be aligned. This can be done with a Pry Bar inserted into one of the holes and moved around (See Figure 17). In some cases the Frame Rails may have to be moved slightly, this is the reason the Bolts were only snugged and not tightened. Do not take Hoist off of High Frame untill all Bolts are tightened. There are 8 bolts and Nuts that must be installed into the holes of the Angle Mounts. Snug these Figure 14 Aligning on the LH side between the front and rear angle mount. Figure 15 Aligning on the RH side between the front and rear angle mount. Figure 16 Figure 17 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 5- 5 Frame Rail Installation 4 WD Re-Install High Frame to Tractor: (continued) 5. Install Mounting Tube Bolts. The High frame must still be hung on the Hoist for safety and support, but sitting down on the frame rails. There are 8 Bolts and Nuts that go through the Angle Mounts and the Plates on the end of the Mounting Tubes. There are 2 on each end and 4 on each side. Install these 8 Bolts now but snug them only do not tighten them down yet (See Figure 18). You may need to insert a bar into one of the holes to align them (See Figure 19). 6. Install Bar Mounting Straps. The rear Bar Mounting Straps are the ones that were cut and welded to the tubes, just put the Bolt through these (See Figure 20). Snug the Bolt in using the Lock Nuts. The Front Bar Mounting Strap will have a strap on the Bottom and another one on the top with a bolt on each side. Install these bolts and nuts. Snug them only for now. (See Figure 21). Install the Bar mounting Straps with Bolts and Nuts on the LH and RH Side. Figure 18 7. Tighten High frame Mounting Bolts. Tighten the 8 Bolts and Nuts for the Mounting Tubes (See Figure 18 & 19). Tighten the Bolts for the Bar Mounting Straps, These bolts must be tighten so the straps stay even on both sides so Bars will stay even.

Starter Safety Switch Schematic, Mechanical Cable Operated Valve Type, NOT correct for Optional Joystick (Electronic) Controls. 2. Figure 4 illustrates a common wire harness connection for A-Boom mowers with mechanical cable controls, If the Joystick Optional controls are used the Wiring will be different than shown. 3. Individual installations may vary and are dependent on the electrical and safety system designs of the tractor to which the mower is mounted. 4. Consult the specific mounting instructions to determine the correct wire routing for each specific unit. Common Problems: 1. The tractor won’t start: The mower on/off switch, if left in the “on” position will not allow the tractor to restart. Be sure to push the switch into the “off” position and account for all the tractor safety interlocks to enable the tractor to start. Failure of the tractor starter safety lock system is normally attributed to a failure of the mower on/off switch. Check continuity at the switch. Check for loose connections. 2. Cutter motor won’t start: Normal causes of this type of malfunction include failure of the push/pull switch, failure of the solenoid coil, loose connections, loss of ground, or a blown fuse. If the mower won’t start, check continuity of the system with a test light to find an electrical problem. Problems may also exist in the cutter valve and other systems. 3. The problem may not be in the electrical system, but because there are so many connections that could be malfunctioning it is the best place to start checking. If the electrical connections are ok, go on to the Tractor connections and/or the Tractor components to check for the malfunction. Some times the service technician thinks the best way to eliminate the Mower electrical connection problem is to bypass them; this should never be done, eliminating the starter safety system is dangerous and hard on the Hydraulic System, The Hydraulic System will be trying to start at a low RPM which is not good. Standard Control Valve Operation: 1. This Control valve is the Standard 4 Spool that is remote cable Controlled, The 28 ft model used a 5 Spool valve with the 5 Th. Spool operating the Boom Extension. THIS SECTION WILL NOT apply to the OPTIONAL ELECTRONIC JOYSTICK CONTROLS. This Section mostly shows the 4 Spool Valve, The 5 Spool Valve is mainly the same with the 5 Spool operating the Hydraulic Door option on the Rotary head or the Boom Extension Cylinder on the 28-ft Model. (See Figure 5 & 6) A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 8 - 4 Cylinder Control Valve Installation Standard Control Valve Operation:(continued) 2. The Standard Tandem (Dual) Pump System is Shown, there is a Single Pump System Option available. The Single Pump only supplies the Hydraulics for the Cutter Head Motor and the Tractor Hydraulic System is used to supply the Boom Cylinder movements. The Schematic is very much the same except the Cylinder Control Valve Hose connections are run to and from the tractor instead of the way they are shown in the Schematic on the next page. (See System Schematic drawings for Pump Repair Section) Pressure One Way Restrictors Return "B' Side Ports Inlet Cover "A" Side Ports Handle Swing Lift Dipper Tilt Figure 5 3. The Control valve will bolt on the top of the High Frame on the right hand side. There is a tab welded to the Frame that has two holes in it, the Valve mount plate will bolt to this tab and the valve will bolt to mount plate (See Figure 6) The Valve in Figure 6 shows the Hoses and Control Cables already connected, this is for illustration only. The Control Cables and Hoses are connected after the Valve is bolted to the mount plate. Most of the Hoses shown in figure 6 are running from the Boom. These Hoses must be connected to the correct Port on the valve and to the correct side to operate correctly. 5 Spool Valve Shown Figure 6 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc.

When you assemble this you will not have to assemble the Valve, it will come to you already assembled as a 4 Spool or 5 Spool depending on which model and which option you ordered. Hoses must be connected to the correct Valve Port so the Control Funtions will operate in the correct direction. A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 8 - 6 Cylinder Control Valve Installation Cylinder Hydraulic Control Circuit: (See Figure 2 & 3) A Hydraulic power for the cylinder control circuit is taken from the second (smaller) stage of the 1. hydraulic pump. Oil is supplied through hose 2 to the four (or five) spool control valve where it is directed to the appropriate cylinder through the cylinder hoses. All of the cylinders are double acting. The system is protected from excessive pressure by an adjustable pressure relief valve located on the inlet section of the valve. The pressure relief valve is factory set at 2000 PSI for the 17, 20, & 23 foot booms and to 2500 PSI on the 28 foot booms. In addition, at least 3 individual cylinder circuits are protected by a non-adjustable work port relief valve (See Specifications in the Service repair Manual). 2. One way restrictors are added to the valve sections such that the return flow from the cylinders when performing gravity aided function will slow the flow of return oil and allow for a more controllable movement of the boom. (See the specifications for size of restriction and location in the Service repair Manual). 3. Oil is returned from the valve through Return hose to the Cutter / Motor Control valve where it then passes through Return hose into the return filter and into the tank. 4. The valve utilized on the A-Boom mowers to facilitate the control of the boom movement functions is either a * 4 Spool or * 5 Spool, open center, sectional, manually operated valve. The manual operation is performed with the use of normal directly attached valve handles or through the use of cables and remote mechanical levers. * The 5 Spool has one more Spool than shown below, it is to operate the Boom Extension on the 28 ft; Boom or to operate a hydraulic activated Door on some heads. The 5 th spool will be located between the Dipper and Tilt Spool shown in figure 3. (See Figure 15 later in this book) 5. Although similar in appearance, each valve section is specifically designed to perform the specified function for which it is assigned. The Valve is shipped assembled and should not be disassembled during unit assembly. "B" Port Side "A" Port Side Control Cable Attachment Spool Detent Assembly Tilt Tilt * Boom Extend ?

Section 8 - 7 Cylinder Control Valve Installation Cylinder Hydraulic Control Circuit: (continued) 6. Hydraulic Cylinder Hoses. The Hoses for the Hydraulic Cylinders will be marked with bands that have the Part Numbers on them. These part numbers will vary with the size of the Boom Model. The 28 ft. model will have more hoses for the Boom Extend Function, the model with the Hydraulic Door on cutter head willhave more hoses. To find which Hose you have you will need to consult the Parts / Operators manual. When connecting the Hoses to The Valve use these numbers to connect the correct hoses to the correct ports. It may be required that you do some tracing of hoses to find which hose is hooked to which end of a Cylinder. Listed below is a list of which end of Hydraulic Cylinder should be connected to which Port on valve. (See Figure 2 & 3) MECHANICAL VALVE MODELS Cylinder Rod End / Port Base End / Port Tilt Extend / Door Dipper Lift Swing ("B") ("B") ("B") ("A") ("A") ("A") ("A") ("A") ("B") ("B") Standard Only used with 28' Model or Optional Cutter Door) Standard Standard Standard You must consult the Parts Manual to determine correct Hoses used on the Model you have. Also the type Head used will make the Hose vary. There is a Electrical control valve Option, this will make a difference of which hose is connected where. If the hoses are connected to the wrong side of valve it should not damage any thing, it will mean that the control lever function will be reversed or may not work at all because the Relief Valve is in the wrong direction of Oil Flow to operate.. Changing the Hoses on the hose ports of the valve will change this. REMOTE CABLE OPERATION AND INSTALLATION: 1. Remote operation of the boom movement control valve can be achieved with the use of cables and remote actuator handles. The remote operation system is standard equipment on cab tractor units and can be installed on ROPS tractors as well (See Figure 4). Four cable lengths are available and should be ordered based on the length required to reach from the valve to the Operator’s location with out binding or kinking. Cable lengths are limited to 48,60,72 and 102 inches. 2. To install the cables to the valve, each valve section will require a cable installation kit (4 kits for a 4-spool valve, 5 kits for a 5-spool valve etc.). Each individual valve connection kit can be ordered using part number 02971274. Figure 4 displays the contents of each kit. Cables are not included in Cable Connection Kit.

Turn the cable eye Jam nut on the threaded cable end until it bottoms. Thread the Cable Eye onto the cable end until it bottoms on the cable. Turn the eye to align with the spool end and secure the jam nut against the cable eye. (See Figure 6). 5. Slide the cable eye into the slot in the spool and align the holes. Insert the connection pin and install the retaining pin into the hole in the connecting pin and secure by bending both ears of the retaining pin back and around the connecting pin. (See Figure 7). Figure 6 6. With the cable attached to the valve, turn the Flange/Sleeve Assembly back onto the threaded cable end until it is flush with the valve face. When turning on the assembly, make sure that the valve spool remains in the neutral position. (See Figure 8). 7. Tighten the Jam Nut onto the Flange/Sleeve Assembly to lock it into position. (See Figure 9) Figure 7 8. Tighten the Flange into position using the two allen head screws. Use a flat washer to support a lock washer on each bolt. (See Figure 10) 9. Interference will occur between the Flange/ Sleeve Assembly and the casting of the Inlet Section on the Valve Section next to the Inlet Section. To compensate, the provided shims should be placed on the Flange/Sleeve Assembly under the flange (See Figure 11) Figure 8 Figure 10 Figure 9 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 8 - 10 Cylinder Control Valve Installation REMOTE CABLE OPERATION AND INSTALLATION: (continued) 10. Each cable is controlled by the operator with the use of single axis control handle assemblies. A single control handle assembly is required to operate each individual valve section. The control handle assemblies are ordered as PN 02971243 Control Assembly - Controller End Installation Procedure: 1. Each controller assembly comes fully as- Figure 11 sembled. All required hardware etc. is included. The control cables are not included with the control handles and should be ordered separately. The Controller must face forward as shown or controls will be backward (See Figure 12) Tractor Front 2. To attach the cable, manipulate the controller handle so that the attachment nut is exposed as shown. Remove the lower most nut and screw from the controller housing. Thread the cable nut into the controller attachment nut and tighten. (See Figure 13) Figure 12 3. Allow the controller handle to return to neutral. Slide the cable guide tube into the control housing and reinstall and tighten the housing screw. 4. Check the operation of the spool, cable and controller. Some adjustment at the valve end may be required too ensure that the spool returns to neutral when the controller is in the neutral position. (See Figure 14) 5. The control lever assemblies utilizes a small spring to make up for free play in the cable to valve connection. The control valve spool spring provides the centering capabilities of the controller and the valve spool. Lack of centering at the controller is normally attributed to poor adjustment at the valve to cable connection or binding of the cables due to poor routing. Figure 13 6. The control lever assemblies will bolt together to form a group of handles, there will be 4 for thr 4 spool valve and 5 for the 5 spool valve. Also the "ON" and "OFF" Switch will bolt to the Handles (See Figure 15) A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc.

It is important to plumb the motor so that it rotates to deposit the spoil properly. The direction of rotation can be observed by standing behind the Ditcher Head, beside the right rear tire. If the Ditcher rotates 'clockwise' it is plumbed for forward rotation and the spoil will be deposited away from the tractor. If the Ditcher is the reverse design then the proper rotation is counter-clockwise when observed from the rear. Do Not try to reverse Ditcher from Rotation it was designed for, it will not work. The Forward and reverse Rotation Models do not use the same Blade Assembly. 4. Note: The two hoses (P/N 02961054) connecting the main boom to dipper arm are used to connect the Ditcher motor. The 90 degree fittings attach to the fittings on the main boom and the straight fittings attach to the 90 degree fittings on the hydraulic motor. See Figure 69 below.

DO NOT START TRACTOR untill you have filled Hydraulic Oil Tank to a level as shown in Sight Glass gauge and fill the Suction Hose to Pump with Oil. 2. Remove Filler Cap. Remove Filler cap only when ready to fill hydraulic Tank with Oil. Do Not leave the Cap off and the system Open, always keep sytem closed when possible. Avoid any oil contamiantion. (See Figure 1) 3. Avoid Hydraulic Contamination by filtering the Hydraulic Oil while filling the Hydraulic Tank. Filter buggies or carts are commercially available for Hydraulic system clean-up and Oil transfer. These consist of high capacity filter, a Circulating Pump, a Drive Motor and hoses for connecting to the units hydraulic system. When adding Oil always use Clean new Oil from a sealed container, If you suspect the Oil of being contaminated don't use it. (See Figure 2 & 3). It is best to always use a filter system when adding even new oil. FIGURE 1 4. When adding Oil in the field keeping it clean is critical, do not use dirting funnels or hoses. Do Not open Hydraulic tank or any contaners unless the openings have been cleaned first. The outside of the containers must be clean. If a windy dusty day do not fill and allow dirt to blow into oil. Always add Oil using a pump systemwith at least a 10 Micron filter system. (See Figure 4) FIGURE 3 FIGURE 2 FIGURE 4 A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 11 - 2 Fill Hydraulic Tank Fill Hydraulic Tank with Oil: 5. Fill Tank. Fill the Hydraulic Tank (See Figure 4) Fill tank till the Oil is visable in the sight Gauge (See Figure 5 & 8). This will fill tank for the start but it will have to filled again later. 6. Fill Suction Hose with Oil. Remove the Suction Hose at the Tank (See Figure 6) and fill the hose with clean oil, THIS IS A MUST DO. The Suction Hose must be filled with Oil to prevent Dry strat up of Pump. Dry start up of PUMP will damage the Pump. After filling suction Hose reinstall it and tighten down Hose Clamp.

Section 12 - 1 Start-up Instructions: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Read all safety instructions. Decals on the A-Boom warn you of particular and multiple Hazards. Many decals are attached close to part of the A-Boom where there is a possible hazard. Read and make sure you understand the safety messages before you operate the ABoom. Keep all decals clean and readable. Replace lost or damaged decals. Before operating, read all the safety and operating instructions in the Operator's Manuals for both the tractor and mower. When the hydraulic tank has been filled, The Pump Suction Hose filled with Hydraulic Oil and the mower unit (Head) properly assembled, the unit should be started up. NOTE: Make sure that no materials, tools, or jacks have been left under the mower head. Make sure the front and rear of the mower are properly guarded to prevent any foreign objects from being thrown by the mower. All other workers should be kept a safe distance from the unit before the mower is started. Start the tractor and idle at a slow engine speed until oil is being pumped. Check for any leaks, this is easiest with an assistant watching for leaks. Do not run if Oil is leaking. Bleed the air out of all hydraulic cylinders one at a time by extending them to their full length. DO NOT SWING THE BOOM till last and you have gone to the Rest Stop and Support Section for instructions. Engage the Cutter Control Valve at low engine rpm and run the mower slowly for a short period until all air is removed from the hoses. Keep all persons WELL CLEAR of mower since Blades can THROW OBJECTS with great velocity for a considerable distance! KEEP CLEAR! Run the mower at a low tractor engine speed until the mower Hydraulic Sytstem gets the Air out off it. Operate at an engine speed that keeps the filter restriction gauge reading in the "Green Zone". With the hydraulic warm, bring the tractor speed up to normal operating speed. If the filter gauge reads in the red zone, stop the unit, release all hydraulic oil pressure, and Check the filter element in the tank mounted filter or any Hose that may be kinked. Restart the tractor and mower unit and again check the filter gauge (oil must still be hot). If the filter gauge reads in the red when first started and does not drop as oil warmss, then something is wrong, contaminants have been introduced into the hydraulic system or some thing connected wrong. You may need to repeat previous steps again until the gauge reads in the green. Check the fluid level in the Hydraulic Tank and add oil if required. As the air has been forced out of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the oil level. The Hydraulic Oil must be at least at the level of the Sight Gauge on the side of the Tank. Basic trouble shooting guide for first start up. A. Electrical solenoid valve does not work - check wiring, possible faulty switch, possible faulty solenoid. B. Pump is making noise - check for obstruction in suction hose and tank suction assembly, check alignment of pump driveshaft. C. Cylinders will not raise - hoses from cylinder incorrectly connected to valve bank, pump not suppling oil. D. Cylinder rises slowly - hoses from cylinder incorrectly connected to valve bank, work port reliefs on valve bank set too low - replace as required. E. Filter reads in red - viscosity of oil too high - wait until oil heats up before checking filter gauge. If gauge reads in red even after unit is hot, then the filter must be replaced. A-Boom (JD 6615 / 7615 Asy Instruction Manual) 07/03 © 2003 Alamo Group Inc. Section 12 - 2 Post-Assembly Check List: 1. Is oil level in the tank even with the sight gauge on the tank? 2. Has the proper oil been used in the system? Proper oil is Universal Tractor Hydraulic. 3. Does Boom machine movement match operation decal - Swing, Lift, Dipper, Tilt? 4. Is control valve free and does it not stick? 5. Are all hoses tight and do not leak? 6. Are all decals in place? See Safety Section in Manual for decal description and placement. 7. Does tractor pass Alamo Group Mower Stability Test? 8. Have all grease points been adequately greased? 9. Are all bolts tight? 10. Have all hoses been properly routed so that hoses do not kink or bend when boom is articulated through all motions? 11. Does starter lockout device work correctly on machine? Tractor should not start if mower switch is on. 12. Is swing cylinder pinned in correct hole? On rear-swing type machine cylinder should be pinned to outside hole. On front-swing type machine cylinder should be pinned in inside hole. 13. Is machine equipped with proper operator protection? Must have cage or cage panels. 14. Does mower operate when on/off switch is on? Stop when switch is off? 15. Is head rotation correct? On rotary heads (looking from the top of the deck) rotation should be clockwise so that debris will be thrown away from the tractor. On flails, rotation can be forward or reverse, but forward rotation is standard. 16. If furnishing a square head, are spindle housing bolts tight? Is spindle assembly tight? Are bolts that hold blade bar to spindle tight? 17. Does head operate smoothly at normal operating speed? Head should not vibrate excessively.
