Machine Description
Design
The RG13II STUMP CUTTER is designed for your maximum benefit per dollar spent. The machine is constructed for durability and easy maneuvering, for those hard to reach tree stumps and roots. Its 11” diameter x 3/8” thick cutting wheel with 8 replaceable carbide-tipped teeth is powerfully driven by a Honda 13 horsepower engine. The operator benefits from a steel cutting wheel guard and full protection from heavy rubber curtains below the chassis. Other special features of the RG 13 STUMP CUTTER include; an operator’s presence system, adjustable handlebar positioning, centrifugal clutch for easy starting, steel guards surrounding moving parts and convenient access for tightening the V - belt.
How it works
The machine removes tree stumps by the repeated gradual sweeping of a multi-toothed high-speed rotating cutting wheel. The cutting wheel has teeth on its side, in a strategic pattern. The rotating cutting wheel takes a sweep from one side of the stump to the other, each tooth rapidly tearing and stripping away small pieces of stump. After each sweep of 1 to 2 inches of depth, the cutting wheel is advanced deeper into the stump, and the procedure is continuously repeated, under the precise control of the operator, until the stump is satisfactorily removed.

Slope Operation
Machines that are operating safely in various applications depend on these criteria: the machine model, configuration, machine maintenance, operating speed of the machine, conditions of the terrain, fluid levels, and tire inflation pressures. The most important criteria are the skill and judgment of the operation.
A well trained operator that follows the instructions in the
Operation and Maintenance Manual has the greatest impact on stability. Operator training provides a person with the following abilities: observation of working and environmental conditions, feel for the machine, identification of potential hazards, and operating the machine safely by making appropriate decisions.
When you work on side hills and when you work on slopes, consider the following important points:
• Speed of travel – At higher speeds, forces of inertia tend to make the machine less stable.
• Roughness of terrain or surface – The machine may be less stable with uneven terrain.
• Direction of travel – Avoid operation the machine across the slope. When possible, operate the machine up the slopes and operate the machine down the slopes.
• Place the heaviest end of the machine uphill when you are working on an incline.
• Mounted equipment – Balance of the machine may be impeded by the following components: equipment that is mounted on the machine, machine configuration, weights, and counterweights.
• Nature of surface – Ground that has been newly filled with earth may collapse from the weight of the machine.
16
RG13II Operation • Maintenance • Parts
• Surface material – Rocks and moisture of the surface material may drastically affect the machine’s traction and machine’s stability. Rocky surfaces may promote side slipping of the machine.
• Slippage due to excessive loads – This may cause downhill tracks or downhill tires to dig into the ground, which will increase the angle of the machine.
• Width of tracks or tires – Narrower tracks or narrower tires further increase the digging into the ground which causes the machine to be less stable.
• Implements attached to the machine hitch or drawbar
– This may decrease the weight on the uphill tracks.
This may also decrease the weight on the uphill tires.
The decreased weight will cause the machine to be less stable.
• Height of machine working load. When the working loads are in higher positions, machine stability is reduced.
• Operated equipment – Be aware of performance features of the equipment in operation and the effects on machine stability.
• Operating techniques – Keep all attachments or pulled loads low to the ground for optimum stability.
• Machine systems have limitations on slopes – Slopes can affect the proper function and operation of the various machine systems. These machine systems are needed for machine control on slopes.
• Note: Safe operation on steep slopes may require special machine maintenance. Excellent skill of the operator and proper equipment for specific applications are also required. Consult the Operation and Maintenance
Manual sections for the proper fluid level requirements and intended machine use.
Work Tool options - Attachments
Only use work tools that are approved by Rayco for use on
Rayco machines. Refer to the Operation and Maintenance
Manual, Rayco options”.
If you are in doubt about the compatibility of a particular work tool with your machine, consult your Rayco dealer.
Make sure that all necessary guarding is in place on the host machine and on the work tool.
Always wear protective glasses. Always wear the protective equipment that is recommended in the work tool’s operation manual. Wear any other protective equipment that is required for the operating environment.
To prevent personnel from being struck by flying objects, ensure that all personnel are out of the work area.

Guards (Operator Protection)
There are different types of guards that are used to protect the operator. The machine and the machine application determines the type of guard that should be used.
A daily inspection of the guards is required in order to check for structures that are bent, cracked or loose. Never operate a machine with a damaged structure.
The operator becomes exposed to a hazardous situation if the machine is used improperly or if poor operating techniques are used. This situation can occur even though a machine is equipment with an appropriate protective guard.
Other Guards (If Equipped)
Protection from flying object and/or falling objects is required for special applications. Logging applications and demolition applications are two examples that require special protection.
A front guard needs to be installed when a work tool that creates flying objects is used. Mesh front guards that are approved by Rayco or polycarbonate front guards that are approved by Rayco are available for machines with a cab or an open canopy. On machines that are equipped with cabs, the windshield should also be closed. Safety glasses are recommended when flying hazards exist for machines with cabs and machines with open canopies.
If the work material extends above the cab, top guards and front guards should be used.
Additional guards may be required for specific applications or work tools. The Operation and Maintenance Manual for your machine or your work tool will provide specific requirements for the guards. Consult your Rayco dealer for additional information.

NOTICE
Always allow a cold engine time to warm up before cutting a stump.
THE STUMP CUTTER’S CUTTING WHEEL IS
EXTREMELY POWERFUL. CONTACT WITH THE
CUTTING WHEEL WILL RESULT IN SERIOUS
INJURY OR DEATH.
NEVER LEAVE THE CONTROLS WHEN THE
CUTTING WHEEL IS ROTATING.
NOTICE
The speed at which the blade moves is dependant on the position of the throttle. To increase the rate of blade movement, increase the engine RPM’s by adjusting th throttle higher. Decrease the engine
RPM’s to decrease the rate of blade movement.
NOTICE
ONLY THE PORTION OF CUTTING WHEEL WITHIN
THE 80° AREA SHOWN ABOVE SHOULD ENGAGE
STUMP. NEVER UNDERCUT THE STUMP OR USE
THE BOTTOM OF THE CUTTING WHEEL FOR
CUTTING PURPOSES.
Helpful Tips for Operating Machine
• Use smooth, comfortable speeds while operating.
• When it is desired to cut smaller roots, it may be more effective to do so before, rather than after, cutting the stump.
• Should the chip buildup become excessive when cutting, shut off the machine, wait for the cutting wheel to stop rotation, retract the machine from the stump, and rake away the chips.
• On larger stumps, when cutting from one side, eventually a tire may tend to roll into the hole. This may be prevented by moving the machine to another side of the stump to continue removal, or by filling the hole with chips before continuing.
• NEVER go near the cutting wheel when the machine is turned on. Turn off the machine first.
• Always cut with the machine downhill, below the stump.
• Use extreme caution on slopes. Slopes, combined with less than ideal traction (ice, snow, gravel, leaves, wet grass) can allow the machine to move unexpectedly.

Stump Removal Procedure
1: Prepare the machine at the stump:
4: Cut another level of the stump:
• Drive the machine into position with the cutting wheel near the top edge of the stump.
• Move the engine throttle to IDLE.
• Start cutting wheel rotation
• Increase the engine to increase the cutter wheel.
2: Remove the roots:
• Raise the cutting wheel above the stump once again, and starting with the cutting wheel swung to one side, advance the machine slightly (about 2”) and repeat
STEP 3.
Repeat STEP 4 consecutively
5: Cut Remaining Roots:
• Swing the cutting wheel to one side, then lower it into the nearside roots that may be buried at the foot of the stump, and swing the cutting wheel across them until they are sufficiently removed
3: Cutting the stump properly:
• Raise the cutting wheel to the top of the stump and advance the machine to a combined position where the center of the shaft remains just above the top of the stump, such that upon swinging the cutting wheel, a bite approximately 4” deep may be taken.
• Sweep the cutting wheel across the stump, taking an approximately 2.75” deep bite.
• After the first bite is taken, lower the cutting wheel about
2” while is off to the side and swing the cutting wheel across for another bite.
• Continue repeating this procedure until all of the amount of stump in the path of the downward swing of the cutting wheel is gone.
• Cut the remaining roots as described in STEP 1 until the entire stump is satisfactorily removed.
• After the stump has been fully removed, stop the cutting wheel rotation. Raise and center the cutting wheel.
• Machine is ready for travel to the next destination
6: Once the Stump is completely cut:
• Reduce the throttle to IDLE and shut off the cutting wheel rotation.
• Stop the cutting wheel rotation quickly by gently lowering the cutting wheel into the soil.
• Fully raise and center the cutting wheel. The machine may then be self-propelled to the next destination

Grease and Oil Buildup - Remove
ACCUMULATED GREASE AND OIL ON A MACHINE
IS A FIRE HAZARD. REMOVE SUCH DEBRIS WITH
STEAM CLEANING OR HIGH PRESSURE WATER.
NOTICE
When cleaning the machine the use of mild soap and water must be used for the first 90 days. Harsh cleansers or solvents will strip paint off machine.
After 90 days stronger cleaners may be used.
For cleaning with a hot water cleaning device, use a spray steam with a pressure not exceeding 426 psi (2937 kPa) to prevent damage to painted areas of the components.
Lubricate the Fittings
NOTICE
Pump grease in slowly, and carefully to prevent damage to the bearing seals. Use extreme caution when using a high pressure or high volume grease gun.
1
Lubricate the two fittings as shown(1) (One on each cutting wheel bearing). Slowly add grease until you see new grease purging out of side bearing. Performing this procedure every
10 hours will prevent debris and moisture from entering and damaging the bearing.
Lubricating Grease
All Rayco stump cutters are completely serviced at the factory before shipping. The operator should check all grease fittings to familiarize himself with their location and acquaint himself with the correct service schedule.
Use the normal shutdown procedure (See “Operating
Instructions”), before lubricating the machine.
Cutting Wheel - Check
One of the most critical elements of the stump cutter are the cutting teeth. They are also the most subject to damage and wear. In the course of cutting stumps they not only make contact with wood, but also encounter a numerous assortment of abrasives and objects in the stump’s environment, such as dirt, stones, and occasionally a large rock or buried scrap.
The loss of and wear of teeth can significantly impair the efficiency of a stump cutter and also result in overexposure of other teeth, resulting in premature failure or wear. Therefore it is important to make frequent observation of the condition of all of the cutting teeth, and replace or have sharpened any missing and significantly worn teeth, as soon as feasible.
Read all of the instructions on the following pages before beginning to change cutting teeth.
Using Rayco Teeth
Rayco Manufacturing Inc. recommends only genuine Rayco
Cutting Tools for use on Rayco Stump Cutters and Forestry
Mowers. The use of non-Rayco cutting tools or cutting wheels will void the machine warranty. Rayco’s cutting tools, cutting wheels, and mower rotors are specifically designed to provide optimum performance in many ways. The use of non-Rayco parts will compromise this optimum performance.
• Safety: Rayco’s cutting tools are always attached with at least two fasteners. This redundant fastening system is far safer than those systems employing only one fastener.
Rayco’s cutting tools are also more visible than some of the other cutting tools that are available. Some of the cutting wheels available today are “transparent” which can lead to an operator or bystander becoming confused as to the actual limits of the cutter tool.
• Proper Balance: Rayco’s cutting wheels and mower rotors are designed to achieve a dynamic balance that avoids vibration. Using other cutting tools can set up vibrations that will harm the machine’s structure & reduce bearing life.
• Number of Teeth for Depth of Cut: Rayco’s cutter wheels are designed to provide an economical cutting wheel assembly solution. The teeth are spaced to provide a maximum depth of cut for the number of teeth on the wheel. Some of the wheels available today use a large quantity of teeth to get the same depth of cut that a
Rayco wheel will achieve with half the teeth. While the individual tooth cost may be less, the overall costs are more. Additionally, having too many teeth in the stump at any one time can lead to aggressive “grabbing” of the stump, causing the stump cutter to violently hop. This can cause injury to both man & machine.
• Tooth Projection: Rayco’s stump cutter teeth are specifically designed to ensure that the carbide tip can
30
remove a clear “kerf” from the stump without the body of the tooth ever contacting the stump. This concept reduces drag, which maximizes the use of the machine’s horsepower. This also reduces wear on the tooth body and on the attachment hardware. Many of the other cutting tool systems available today do not address this important aspect of cutting.
• Cutting Tool Dimensions: Rayco’s stump cutting teeth are carefully designed to have the proper size of carbide tip. Carbide tips ultimately become dull, and using large, oversized carbide tips will induce extreme impact energies into the machine’s structure.
• Debris Retention: Rayco’s cutting tool patterns are designed to minimize the retention of debris in between the cutting tools. This debris can cause imbalance. This debris can also become a dangerous projectile. Non-
Rayco cutting tools may retain more debris.
Changing Teeth
NOTICE
Read all of the following instructions before beginning to change cutting wheel teeth.
Support the cutter wheel in a raised position when changing teeth.
RG13II Operation • Maintenance • Parts
Maintenance
5) Position teeth as shown in the diagram in the Parts manual. Straight and angled teeth should be staggered as shown in the drawing.
6) When using Rayco brand square-shanked teeth, set the extreme edge of each tooth 1¼” away from the edge of the pocket.
7) When using Rayco SUPERTEETH, because of one piece construction, no pre-setting of the tooth is required.
8) Make sure teeth are placed in coordination with wheel rotation.
9) After setting each tooth pair, tighten the socket head bolts to 135 to 145 foot-pounds.
NOTICE
Do not hammer the tip of a tooth. Due to the super hardness of the tooth, it is brittle and may chip from such treatment.
Replacement teeth and pockets are available from your Rayco dealer or direct from Rayco. Refer to the Parts manual for part numbers.

1) Clean all dirt from the cutting wheel (2) and teeth (3).
2) Remove the socket head bolts (4) from the teeth (3).
(The 1/2” hex key provided with the machine may be used.)
3) Check the cutting wheel for cracks. Replace the wheel if it is cracked.
NOTICE
The drawing in the Parts manual represents the exact location required for positioning each tooth.
When followed exactly, optimum cutting wheel performance is attained.
There are four types of Superteeth, as shown in the above diagram. The counter bored teeth are on one side of the cutting wheel, the tapped teeth on the opposite side. The tips of the bent teeth will always point away from the cutting wheel.
Sharpening Teeth
NOTICE
Sharpening cemented carbide cutting teeth requires a special process. Have your teeth sharpened only by a qualified machinist for obtaining a proper edge and to avoid injury.
4) Carefully select and properly position each tooth according to diagrams.
Do not allow any tooth to wear too much before sharpening.
Discard any tooth that has lost more than 1/8” of original bite.
The teeth must be removed from the cutting wheel for proper sharpening.

Tooth Sharpening Guidelines
1) Obtain an unused tooth for comparison.
2) Discard any tooth that has lost more than 1/8” of original bite, whether lost through usage or grinding.
3) Grind off a minimal amount from the end, just enough to restore the original taper and radius on the end. The end of the cemented carbide tip and the end of the steel shank should be flush after grinding.
6) Remove the 3 pan-head screws from the pre-cleaner cap, then remove the cyclone housing and air guide.
Wash the parts with water, dry them thoroughly, and reassemble them.
7) Be sure to install the air guide as shown in the illustration.
8) Install the cyclone housing so the air intake tab fits into the groove in the pre-cleaner cap.
9) Wipe off any dirt from the inside of the air cleaner base and cover using a moist rag. Be careful to prevent dirt from entering the air duct that leads to the carburetor.
10) Place the foam air filter element over the paper element, and reinstall the assembled air filter. Be sure the gasket is in place beneath the air filter. Tighten the air filter wing nut securely.
11) Install the air cleaner cover and tighten the wing nut securely.
Follow the directions found in the Honda Engine Operation
Manual.
Air Intake - Check
Follow the directions found in the Honda Engine Operation
Manual.
Park Brake Adjustment - Check
Engine Combustion Air Cleaner -
Check
A dirty air cleaner will restrict air flow to the carburetor, reducing engine performance. If you operate the engine in very dusty areas, clean the air filter more frequently. Do not operate the engine without an air filter, or with a damaged air filter as this would allow dirt and abrasive debris into the engine causing rapid wear and reduced engine life.
To check the air filter, remove the air cleaner cover and inspect the condition of the dual filter elements. Always replace dirty or damaged filter elements.
1) 1. Remove the top wing nut from the air cleaner cover, and remove the cover.
2) 2. Remove the second wing nut from the air filter, and remove the filter.
3) 3. Remove the foam outer filter from the paper inner filter.
4) 4. Inspect both air filter elements, and replace them if they are damaged. Always replace the paper air filter element at the scheduled interval or sooner if operated in very dusty areas.
5) 5. Clean the air filter elements if they are to be reused: a. Paper air filter element: Tap the filter element several times on a hard surface to remove dirt, or blow compressed air (10-30 psi max) through the filter element from the inside. (Never try to brush dirt; brushing will force dirt into the fibers).
b. Foam air filter element: Clean in warm soapy water, rinse and allow to dry
