Make this adjustment as follows: NOTE If skid shoes plow soft soil so much that they stop tractor, they can be removed completely. 1. Stop tractor, set parking brake, and be sure tractor PTO lever is in disengaged position. 2. Raise rotary tiller to its transport position. 3. Stop engine and remove ignition key. 4. Remove spring clip and pin (item B) and slide skid shoe up or down to desired height. Then reinstall pin and spring clip to secure skid shoe. Be sure both skid shoes are set to same height. Figure 8. Skid Shoes Soil Conditions Avoid tilling soils that are too wet or too dry. Tilling wet, muddy soil is especially bad. Such soil will ball, leaving chunks that harden as they dry. Mud can also collect on the tines, drive shaft, and belts and thereby cause equipment damage. 10 Normal Care CONTENT OF SECTION Your rotary tiller was designed and built to provide years of service with only minor care. This care, however, must be performed to keep it in good operating condition and to avoid costly repairs. This section shows you how to provide the necessary care. SCHEDULED CARE The only care required for the rotary tiller on a regularly scheduled basis is lubrication. The rotary tiller must be lubricated as shown in figures 9 and 10 before the first use and after every 8 and 25 hours of operation. A Maintenance Record (figure 11) is provided to help you document all operating hours and maintenance repair actions. NORMAL STORAGE To protect your rotary tiller, store it in an enclosed, dry area. Clean the tines and body of the rotary tiller to remove excess dirt and plant matter. This can be done easily with a hose. OFF-SEASON STORAGE When the rotary tiller is to be stored for 30 days or more, take precautions as follows: 1. Remove rotary tiller from tractor. 2. Clean the entire tiller, including the tine assemblies. 3. 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. 4. Lubricate rotary tiller. (See figures 9 and 10.) NOTE Keep grease and oil off belts and pulleys. Symbol Use Apply With Procedure Lithium base automotive grease. Grease gun 1. Wipe fitting clean with rag. 2. Apply 2 or 3 shots of grease. 3. Wipe up any excess grease. Figure 9. Lubricate Tine Shaft Bearings (Every 8 Hours) 11 Normal Care NOTE Keep grease and oil off belts and pulleys. Symbol Use Apply With Procedure Lithium base automotive grease. Grease gun 1. Wipe fitting clean with rag. 2. Apply 2 or 3 shots of grease. 3. Wipe up any excess grease. SAE 30 oil Oil can Clean indicated area and apply 2 or 3 drops of oil. Figure 10. Lubricate Rotary Tiller (Every 25 Hours) 12 Maintenance Record Date Hours Used Lubrication Maintenance/Repair Figure 11. Maintenance Record 13 Troubleshooting CONTENT OF SECTION This section of the manual tells you how to troubleshoot some of the more common and easily corrected rotary tiller problems. The same type of data for the tractor can be found in your tractor owner’s manual. For problems not covered in these manuals, it is recommended that you contact your dealer. TROUBLESHOOTING PROCEDURES Troubleshooting procedures are provided in figure 12. To use these procedures, first locate the problem description that best describes the trouble that you have encountered. Check the possible causes one at a time in the order that they are listed. Correct any problems that are found and try to operate the rotary tiller again to see if you have eliminated the trouble. A 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. Problem Cause/Remedy 1. Rotary tiller tines do not rotate. A. PTO lever not engaged. Engage PTO lever. B. Tiller drive belt slips. Check tines and remove any wire, etc. that is binding tines. If problem persists, check for broken tiller idler pulley spring. Replace it if necessary. Otherwise, check and adjust tractor PTO. C. Rotary tiller drive belt or chain broken. Replace as needed. D. Drive belt or pulleys oily. Clean as required. 2. Tills too shallow. A. Tiller raised too high. Lower it using tractor lift. B. Skid shoes set wrong. Raise skid shoes. C. Engine speed too slow. Set engine for 3/4 to full speed. D. Tractor speed too fast. Use slower speed. E. 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 when rolled in your hand. B. Tilling too deep at one pass. C. Tractor speed too fast. Set transmission gear shift or control for slower speed. 4. Tractor handles poorly. A. Tractor ...
