Full engine speed will be necessary when tilling depth and ground conditions require full engine power. Tractor Speed for Tilling The tractor speed affects the tilling depth and the size of the soil particles. The best speed is determined by the soil conditions and land contours. For most conditions, the best speed is obtained in first gear. You may be able to use second gear in soft, loose soil. In either gear, adjust the hydrostatic control for the desired results. Stopping the Rotary Tiller To stop the rotary tiller while it is in operation, flip the REAR CLUTCH switch (item B, figure 5) down and stop the tractor. Do this immediately if you strike rocks that jam and stop the tines. NOTE After striking a foreign object, stop the engine, disengage PTO, remove ignition key, and lower tiller to the ground. Thoroughly inspect the rotary tiller for any damage before restarting. Shield Position The shield (item A, figure 6) prevents throwing of loosened soil and rocks. The rear of this shield should rest on the ground when the tiller is at the desired depth. To adjust the shield height, place different chain links over the hook (item B). For finer adjustment, you can also twist the chain. Figure 6. Shield and Skid Shoes Starting the Rotary Tiller To start the rotary tiller into operation, stop the tractor and proceed as follows: 1. While tiller is raised so tines clear ground, set REAR CLUTCH switch to its on position. 2. Push rear lift control fully forward to its float position to lower rotary tiller. 3. When tines have dug down and skid shoes are resting on ground, start tractor forward. Adjust tractor speed as you proceed to keep skid shoes on the ground. Tilling Depth You will want to till to a depth that suits the seed you will plant. As a rule, till at least 2 inches (50 mm) deeper than the normal planting depth for the seed. The usual planting depth for com, as an example, is 2 to 3 inches (50 to 76 mm). Using the rule above for this example, till the soil to a depth of 5 inches (127 mm) or more. If you till too deeply in a single pass, the soil texture will be coarse. The problem can be avoided by making a number of passes over the same area. Till to a shallow depth on the first pass. Then increase the depth on each additional pass until the seedbed has the proper depth and texture. To control the tilling depth, raise or lower the rotary tiller by adjusting the skid shoes (item C, figure 6). Make this adjustment as follows: 1. Stop tractor, set parking brake, and be sure REAR CLUTCH switch is off. 2. Raise rotary tiller to its transport position. 3. Stop engine and remove ignition key. 4. Remove spring clip and pin (item D) 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. Normal Care NORMAL STORAGE CONTENT OF SECTION Y our 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 7 and 8 before the first use and after every 25 hours of operation. A Maintenance Record (figure 14) is provided to help you document all operating hours and maintenance repair actions. 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 figure 7.) Check gear box oil level. (See figure 8.) Figure 7. Lubricate Rotary Tiller (Every 25 Hours) 9 Normal Care BE SURE TOP IS LEVEL 1. Position tiller so top of gear box is level. 2. Remove check plug. 3. Oil level should be up to bottom of check plug hole. If not, remove fill plug and add SAE 90 weight transmission oil. Be sure to install fill plug again. 4. Install and tighten check plug. piaure 8. Check Gear Box Oil Level (Every 25 Hours) 10 Troubleshooting CONTENT OF SECTION This section of the manual guides you in troubleshooting 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.
