GENERAL INFORMATION SERIAL NUMBERS See Figure 1A-1 for location of serial number. Figure 1A-1. Serial Number Location GENERAL CLEANING Improper cleaning and lubrication of your machine re- sults in many equipment failures. Before any repairs are undertaken, thoroughly clean the exterior of the component to be removed. Use a clean surface to lay out parts being removed. Keep lubricants clean and cover containers not being used. PREPARATION FOR REPAIR Thoroughly clean the mower prior to disassembly and repair procedures. Coat bare metal parts with light oil. The cutting and grooming attachments are exposed to water (used in daily washing), grass clippings, sand, corrosive fertilizers, and foreign objects such as tees. It may be necessary to use bearing pullers and/or wood- en blocks and hammers to free up some parts such as bearings and spacers. When such force is required to remove parts, those parts should be replaced rather than reinstalled on the machine. SAFETY Safety should always be the rule when working on or with machinery. Always use safe practices and com- mon sense when using hand or power tools. Use the suggested procedures in this manual when working with the mower. Throughout this manual signal words will be used to highlight special procedures. The signal words and their meaning are as follows: 1A-2 NOTE Any procedure needing special care when per- forming a procedure. A CAUTION Hazards or unsafe practices which could result in personal injury or product or property damage. A WARNING Hazards or unsafe practices which could result in severe personal injury or death. A DANGER Imminent hazards which will result in severe per- sonal injury or death if precautions are not taken. Decals on the machine denote cautions, warnings, and dangers. These cautions, warnings, and danger decals must be on the machine at all times. If they become worn, torn or painted over, new decals should be in- stalled as shown in Section 14 of this manual. A CAUTION Disconnect the spark plug wire before electric welding is done on components in common ground with engine. A DANGER This machine is equipped with an operator pres- ence control (OPC) system which is intended to protect the operator and others from injury. This machine must never be operated with the OPC system disconnected or malfunctioning. TORQUE VALUES Torque values are given in the following “Torque Speci- fication Chart”.

TIRE SERVICE GENERAL The soft transport tires of the mowers are subject to damage from spikes and other sharp objects. If large punctures or tears occur, it is advisable to take the tire (installed on the wheel) to a qualified tire repair shop or replace the tire. When removing or installing the wheels, always use the kick stand to support the machine. Whenever the wheel hubs are removed, install as described in Section 7C. TIRES Tires are inflated to 6 to 8 psi (41.3 to 55.1 kPa) pres- sure. This pressure gives the best results for average use. Tire pressure should never be less than 6 psi (41.3 kPa) and should be equal in both tires. If tire is removed from the rim it can be inflated to 30 psi, when it is replaced. This assures proper seating of the tire head to the rim. Then reduce the pressure to 6 to 8 psi (41.3 to 55.1 kPa). NOTE Never use grease or oil on the rim when mount- ing a tire. Bead sealing of the tires may be repaired by using tire sealants available from tire repair shops. To apply sealant: 1. Break one bead from seal on rim and push past rim flange or install through valve stem. . Pour sealant into tire cavity. . Reseat bead on rim by inflating the tire to 30 psi. . Rotate tire slowly to spread compound. a ~~ we N . Reduce tire pressure to 6 to 8 psi (41.3 to 55.1 kPa). Screw Latch Lock Spring Nut Washers ~~ Washer Spacer Figure 7B-1.

GENERAL PREVENTIVE MAINTENANCE Preventive Maintenance (PM) is maintenance per- formed to prevent malfunctions and parts breakdowns by periodically and systematically checking equipment and its systems. Preventive Maintenance will cut back corrective main- tenance. SCHEDULING Each machine should be scheduled for preventive maintenance according to the hours used, its severity of use, and the type of environment the machine is used in. Use the manufacturer's recommendation of preventive maintenance. These recommendations can then be altered as experience is gained with the type of equip- ment and the type of environment in which it operates. While performing preventive maintenance tasks the individual should always be alert to conditions that may seem abnormal. If an abnormal condition is detected a determination must be made to either correct the condi- tion immediately or schedule the tractor in the shop for necessary repairs. ADMINISTRATION Record keeping is an important and most often a for- gotten part of preventive maintenance. Jacobsen has developed a PMMRS (Preventive Main- tenance Management Record System). PMMRS PROGRAM KITS The PMMRS kits and replacement forms (see Figure 11A-1) are available directly from your local Jacobsen Distributor.

Repair (Section 12C). 12B-1 ATTACHMENTS SECTION 12C. SHARPENING REELS AND BEDKNIVES GENERAL A reel mower cuts grass in the same way a scissors cuts cloth or paper. Each blade on the reel acts as one scissor blade, and the bedknife acts as the other scissor blade. Grass is trapped between the reel blade and bedknife and is sheared off as the reel blade rotates over the stationary bedknife. A properly sharpened and adjusted reel mower cuts grass clean- ly and with minimum effort. A poorly sharpened reel mower may tear, shread, pull, or leave grass uncut and usually requires more effort. If a mower cuts in streaks, strips or ragged areas, chances are the cutting edges are not properly adjust- ed or they need sharpening. Inspect the blades and bedknife for nicks, gouges, high or low wear areas, or other signs of damage or uneven wear. However, consider these other factors that can contribute to poor cutting performance before grinding and lapping the cutting edges: REEL-TO-BEDKNIFE CLEARANCE (See Figure 12C-1) Clearance between reel blades and bedknife should be 0.001" (0.25 mm). Adjust the reel-to-bedknife clearance as follows: 1. Start adjustment at the leading end of the reel, fol- lowed by the trailing end. The leading end of the reel blade is the end that passes over the bed- knife first during normal reel rotation. 2. Turn jam nut clockwise to bring the bedknife clos- er to the reel or counterclockwise to back the bed- knife away from the reel. a. Slide a feeler gauge or shim stock .001" (.025 mm) between the reel blade and the bedknife. Do not turn the reel. b. Adjust the trailing end of the reel in the same manner, then recheck the adjustment at the leading end. c. When the reel and bedknife are properly ad- justed, the reel will spin freely and will cut a piece of newspaper along the full length of the reel when the paper is held at 90° to the bed- knife. 4. When correct adjustment has been obtained, tight- en locknut securely. Locknut —— 7 e “«—— Jam Nut Figure 12C-1. Reel-to-Bedknife Adjustments DAMAGED MOWER PARTS A gouged bedknife, nicked reel blade, or wavy bed- knife and reel as well as a bent frame, broken welds, worn bearings or loose attaching hardware can cause poor quality cutting. Solve such problems by making sure the bedknife mounting screws and other hard- ware are secure and by replacing parts if damage cannot be corrected by grinding and lapping. 12C-1 ATTACHMENTS SECTION 12C. SHARPENING REELS AND BEDKNIVES BAD BEARINGS, END PLAY OR RADIAL PLAY Check for play in the reel bearings. Excessive play indicates worn bearings or weak bedknife tensioning spring. A CAUTION Never grind and lap a reel in the frame until all end play and radial play are eliminated. End or radial play will cause uneven grinding. Reel blades and a bedknife that are slightly dull or have minor nicks or high spots can be reconditioned quickly and easily by lapping. Both grinding and lap- ping are required when more severe wear or damage exists. If a wave has developed in the bedknife, lap- ping will not solve the problem and the mower reel and bedknife must be ground. A reel worn or incorrectly ground to a conical shape instead of a cylindrical shape will cause a wavy bed- knife and uneven wear. See Figure 12C-2. If diameters А and B are not equal, the reel is conical. NOTE Always correct a conical shaped reel by grinding. A conical reel can cause a wavy bedknife. If diameters A and B are equal the reel is cylindrical. Figure 12C-2. Reel Wear 12C-2 ATTACHMENTS SECTION 12C. SHARPENING REELS AND BEDKNIVES BACKLAPPING 1. Determine if routine backlapping will restore the proper cutting edge. 2. For optimum performance use a bedknife grinder to touch-up the blade, then reassemble and ad- just the bedknife to the reel. 3. Disengage reel clutch and tip machine back to rest on the handles. 4. Carefully remove left-side reel shaft cover and gasket. 5. Thread a 3/8-24 bolt into end of reel shaft and attach lapping machine. a. Apply lapping compound, with a long handle brush, along the entire length of the reel. b. Continue lapping and at the same time make a fine adjustment on the reel and bedknife until there is a uniform clearance along the full length of the cutting edges. 6. Carefully and thoroughly remove all lapping com- pound from reel and bedknife before running the reel in forward direction. BEDKNIFE CONFIGURATIONS The bedknife shipped from the factory with the machine is the 1/16" (1.59 mm) minimum cut “low pro- file” (Part No. 503478) knife. The “high profile” or “tournament” bedknives shown in Figure 12C-3 may be used in place of the “low profile” bedknife. NOTE Check the dimensions of alternative bedknives (Figure 12C-3) before attempting to grind your existing bedknife to meet specific needs. A sim- ple replacement may be all that is necessary.

Dressing the Bedknife After the unit has been in operation for a period of time it may become necessary to dress the face of the bedknife. A flat front face, as shown in Figure 12C-4, should be maintained to insure a good quality of cut. A sharp jagged edge will result in a ragged cut. Cut- ting units that are being used in sandy conditions or on surfaces with a high sand content will require more frequent dressing of the bedknife. The front face should be regularly maintained using a flat file or small hand held disc grinder. BEDKNIFE REPLACEMENT (See Figure 12C-5) NOTE Check the dimensions of alternative bedknives (see Figure 12C-3) before attempting to grind your existing bedknife to meet specific needs. A simple replacement may do the job. Bedknife Shoe Bedknife &-—Screw Figure 12C-5. Bedknife Removal and Replacement Bedknives that cannot be repaired by backlapping should be ground or replaced. The bedknife is held to the bedknife, shoe by flathead screws. When replac- ing a bedknife the bedknife should be lightly ground to level the cutting edge. When a bedknife is installed, clean the backing prior to installation. Secure the installed bedknife by tightening the mount- ing screws, starting with those at the center and work- ing out to the ends. BEDKNIFE GRINDING A DANGER Always wear eye protection when operating a grinding machine. A CAUTION Handle and store grinding wheels carefully. Dis- card grinding wheels that are cracked, badly chipped, or have been dropped. A CAUTION Always install blotter washers between the grind- ing wheel and the flanges. Do not overtighten the flange nut on the grinding wheel. Do not run a grinding wheel faster than specified on the wheel blotters. A DANGER Do not stand in line with a grinding wheel the first three minutes it is run. Never jam a grinding wheel into the work piece, especially when the wheel is not rotating. 12C-4 ATTACHMENTS SECTION 12C. SHARPENING REELS AND BEDKNIVES . Use a wire brush to thoroughly remove dried ma- terial, rust, and scale from the bedknife. . Refer to the grinding machine manufacturer's in- structions for mounting the bedknife and operat- ing the machine. .

Bedknife Grinding Dimensions and Angles 12C-5 ATTACHMENTS SECTION 12C. SHARPENING REELS AND BEDKNIVES NOTE The bedknife end at which the reel first makes contact is called the leading end. A beveled cor- ner (dub) is ground on this end. It is important that the dub be maintained throughout the life of the bedknife. The dub provides an entrance ramp for the reel blade on to the bedknife. If the dub is worn or ground away and not replaced, the reel blade could hook the corner of the bed- knife as it begins contact. 5. After grinding the bedknife, examine the dub. If, through grinding it has become smaller than 0.18" (1.6 mm), hand grind or file the surface to the specified dimensions (see Figure 12C-8). Figure 12C-8. Bedknife Dub REEL REPAIR AND GRINDING Reel blades and a bedknife that are slightly dull or have minor nicks or high spots can be reconditioned quickly and easily by lapping. Both grinding and lap- ping are required when more severe wear or damage exists. If a wave has developed in the bedknife, lap- ping will not solve the problem and the mower reel and bedknife must be ground. NOTE A reel worn or incorrectly ground to a conical shape instead of a cylindrical shape will cause a wavy bedknife. Remove the reel from the mower frame as described in Section 12D of this manual. Prior to grinding the reel, clean, inspect, and repair the reel as follows: e Steam clean or wash the reel. ® Clean the reel thoroughly by scraping off all dried material from the blades. e Inspect the back of each reel blade for irregular sur- face which could cause the guide finger to hang up while grinding. Remove any irregularities. ® |nspect the welds at the spiders. If any have cracked or broken loose, reweld using a #7018 low hydrogen welding rod. ® Straighten any bent reel blades by hammering into shape with a block of steel and a hammer. The method of grinding will depend upon the grinding equipment being used. Set up and operate the grind- ing machine in accordance with the manufacturer's instructions. Exercise the following precautions: 1. Grind the reel blades to achieve the results shown in Figure 12C-9. A CAUTION Handle and store grinding wheels carefully. Dis- card grinding wheels that are cracked, badly chipped, or have been dropped. A CAUTION Always install blotter washers between the grind- ing wheel and the flanges. Do not overtighten the flange nut on the grinding wheel. Do not run a grinding wheel faster than specified on the wheel blotters. A DANGER Do not stand in line with a grinding wheel the first three minutes it is run. Never jam a grinding wheel into the work piece, especially when the wheel is not rotating. A DANGER Always wear eye protection when operating a grinding machine. 2. After grinding, dress each blade (new or old) with a fine hone or block of hardwood to remove grind- ing burrs from the blade. 3. If removed, lubricate and install the reel in the frame as described in Section 12D and bench lap the reel as described in the following procedure. 12C-6 ATTACHMENTS SECTION 12C.

Adjust reel-to-bedknife clearance (refer to “Reel- to-Bedknife Clearance” at beginning of this Sec- tion (12C). 2. Push the kickstand down and tip mower back on its handle. Do not leave the mower tipped back for an extended length of time or engine oil may migrate into the combustion chamber. 3. Loosen nuts on both sides just enough to allow adjusting knob to raise the front roller or turf groomer. Raise both sides an equal amount. 4. Loosen the wing nut and set gauge screw to the desired cutting height. Measure from the gauge bar to the underside of the gauge screw head, then tighten wing nut to lock the adjustment. 5. Place gauge bar between front roller and traction roller, near the outer end of the rollers. 6. Slide screw head over bedknife and adjust knob to close the gap between the roller and the gauge bar. Tighten nut. 7. Repeat Steps 5 and 6 on the opposite end of the reel, then tighten nuts. Recheck and readjust the cutting height if necessary.

TURF GROOMER (Product No. 68579) GENERAL The Turf Groomer® attachment consists of a grooved roller, a vertical blade cutter assembly, a clutch to dis- engage the turf groomer, and a cutter drive assembly consisting of a cogged drive belt and pulleys. Initial set-up of the turf groomer attachment is covered in a separate “Setup and Maintenance Guide, No. 3004453, available from your Jacobsen Distributor. When the clutch is disengaged, the reel rotates with- out the turf groomer cutter assembly rotating. When the clutch is pulled to its extreme outward position and rotated 1/4 turn, its shallow slotted surface pre- vents the clutch hub from engaging the groomer drive pins. A CAUTION When engaging and disengaging the clutch, never hold the reel blades. Use a wood block between the reel blade and bedknife to keep the reel from rotating during service procedure. The most common repairs to turf groomer are replace- ment of the drive belt, pulleys, blades, and roller. There is no grinding or sharpening procedure for the blades. Bent blades can be straightened; broken blades must be replaced. Bent blades must be straightened to prevent damage to the roller. The drive belt should be replaced whenever it is frayed or if the cogs are worn. CLUTCH HANDLE AND END COVER (See Figure 12D-1) Lockwasher Washer Screw | X „” ee Lockwasher Screw Nut Figure 12D-1.

To remove the bearing, loosen setscrews in hex head retaining collars. Slide bearings out of collar. 3. To install the bearings, proceed with steps 4 thru 7. 4. Install bearing shaft in retaining collar. 5. Tighten retaining collar in roller until finger tight. Then back out collar approximately 1/2 turn. 6. Position bearing (see Figure 12D-9) so that the dimension between the outer end of the bearing shaft and the end of the roller is 2-3/16" (55.5 mm) as shown in the diagram below. 7. Tighten retaining collar and torque to 50-55 ft-lbs. (68-75 N.m). CUTTER UNIT REPAIR (See Figure 12D-10) Check the condition of blades, straighten bent blades whenever practical. If blades must be replaced, pro- ceed as follows: 1. Loosen the setscrew and collar from one end of the cutter unit assembly. Be careful to hold re- maining parts, blades, spacers, and shims in place on the cutter shim. 2. Remove broken or damaged blades by alternately removing spacers and blades from the end of the cutter shaft until all necessary replacements have been made. 12D-6 1. Install and position the nut on one end of the shaft so that approximately 1/32" (0.7 mm) threads pro- trude beyond the collar. 2. Install bearing so that the key in the bearing shaft slides in to the groove in the cutter shaft. Position the bearing so that the dimension between the outer end of the bearing race and the end of the threaded shaft is 1-13/16" (56.0 mm) as shown below. After positioning the bearing, secure the bearing with the setscrew in the collar (or nut). Torque the setscrew to 10 ft-lbs. (14 N.m). 3. Refer to Figure 12D-10 and install blades and spac- ers on the cutter shaft. There should be two spac- ers between each end blade and nut and one spacer between each blade. When installing the blades, make sure each blade is installed so that the flat side of the blade rotates toward the bed- knife (ie, rotates toward the rear of the mower, see Figure 12D-12). NOTE This blade-to-bedknife relationship must also be checked when the assembled cutter assembly is installed to avoid installing the cutter assembly backwards. 4. Before securing the blades and spacers, check the cutter unit-to-roller alignment as described in the following section. ATTACHMENTS SECTION 12D.
