If the tiller does not have enough power to bite into the soil, it may propel the tractor forward. 4 Normal Care LUBRICATION Before first use and every four hours, lubricate the tiller as shown in figure 6. CHAIN ADJUSTMENT Every 25 hours of operation or yearly, remove slack from the chain as described in Adjustments section. NORMAL STORAGE Remove excess dirt and plant matter from the tiller and body. (This can be done with a hose.) Store the tiller in an enclosed, dry area. OFF-SEASON STORAGE (30 days or more) 1. Clean the entire tiller, including the tines. 2. Coat the tines with a light film of grease or oil. Coat all other bare metal surfaces with a good quality paint (obtainable from your dealer) or a light film of grease or oil. 3. Lubricate the tiller as shown in figure 6. Figure 6. Lubricate Rotary Tiiler (Every 4 Hours) 5 Troubleshooting ^WARNING For your safety, do not try to adjust or repair the tractor or rotary tiller while the engine is running. Also, always remove the key from the ignition switch before beginning the maintenance to prevent accidental starting of the engine. Troubleshooting procedures are provided in the following chart. Locate your problem and check the possible causes in the order listed. After correcting the problem, try operating the tiller to see if you have eliminated the trouble. Also see the troubleshooting chart in your tractor Operator's Manual. For problems not covered in either manual, contact your dealer. Problem Cause/Remedy 1. Rotary tiller tines do not rotate. A. Tiller clutch not engaged. Pull clutch fully forward. B. Tiller or tractor drive belts too loose. Adjust belt tension. C. Rock jammed in tiller. Remove it. D. Rotary tiller drive belt or chain broken. Replace as needed. E. Drive belt or pulleys oily. Clean as required. 2. Tills too shallow. A. Tiller raised too high. Lower it using tractor lift. B. Engine speed too low. Set engine for 3/4 to full speed. C. Tractor speed too high. Set transmission gear shift for slower speed. D. Ground too hard. Make several passes, tilling deeper on each pass. 3. Tiller leaves ground rough with large clods. A. Ground too wet. Wait until soil does not ball up. B. Tilling too deep at one pass. C. Tractor speed too high. Set transmission gear shift for slower speed. 4. Tractor handles poorly. A. Tractor speed too fast. Use slower speed, especially when running on rough or sloping surfaces. B. Front wheels lifting. Use front counterweight. C. Rear wheels slip. Use rear wheel weights. 6 Adjustments the cover. £ WARNING To avoid serious injury, perform adjustment only with tractor engine stopped. Remove the ignition key to prevent accidental starting. BELT TENSION 1. Engage the tiller clutch. 2. Press downward with your thumb on the exposed part of the belt (item A, figure 7). Thumb pressure should deflect the belt downward about 1 /4 inch (6 mm). If not, proceed with the following steps. Figure 7. Belt Tension Adjustment A. Belt D. Clevis B. Clutch Link E. Pin C. Jam Nut F, Spring Clip 3. Disengage the tiller clutch. 4. Loosen the jam nut (item C). 5. Remove the spring clip (item F) and pin (item E). 6. Turn the clevis (item D) in or out of clutch link (item B). Increasing exposed thread of clevis increases belt tension; decreasing exposed thread decreases belt tension. 7. Reattach clevis (item D) with pin (item E) and spring clip (item F). 8. Engage the clutch and recheck the measurement (step 2). Readjust if necessary then tighten jam nut (item C) firmly against the clutch link (item B). 9. Operate the tiller for a short period then recheck the adjustment. CHAIN ADJUSTMENT I. Locate the screw and nut in the slotted holes on either side of the chain drive housing underneath 2. Place a wrench on the nut and another wrench on the screw head. Loosen, but do not remove. 3. Push the wrenches toward the rear while tightening the screw and nut. This will remove slack from the chain. Do not overtighten. LIFT ROD ADJUSTMENT - Tilling Depth and Ground Clearance Moving the jam nuts (B & C, figure 8) affects the tilling depth and ground clearance. Moving the jam nuts toward the rear increases the tilling depth and decreases ground clearance. Moving the jam nuts toward the front decreases the tilling depth and increases the ground clearance. Initially, position the two nuts so that the lift arm (E) nearly touches the back of the tractor when the tiller is fully raised. If operation shows that greater tilling depth is needed, move the nuts toward the rear. To move the nuts, proceed as follows. 1. Use tractor lift lever to lower tiller to ground. 2. Hold forward jam nut (C) while loosening rear jam nut (B). 3. Move nuts to desired position on lift rod. 4. Hold forward jam nut (C) while tightening rear jam nut (B). The two nuts must be jammed tightely together. 5. Use tractor lift lever to fully raise tiller. Check to be sure that there is reasonable clearance be...
