Thoroughly inspect the rotary tiller for any damage before restarting and operating the rotary tiller. STOPPING THE ROTARY TILLER To stop the rotary tiller while it is in operation, simply move tractor PTO switch to its disengaged position. Do this immediately if you even suspect that the tines are striking rocks. ^WARNING For your personal safety, be aware that tiller does not disengage when tractor clutch is depressed. The tiller is disengaged with the tractor PTO switch. STARTING THE ROTARY TILLER ^WARNING For your personal safety, be aware that tiller may propel the tractor forward when lowered into hard soil or sod. To stop motion in such cases, tiller must be disengaged. Start the rotary tiller while it is raised to the transport position. Do this by moving the PTO switch to the engaged position. Then lower the tiller to the ground slowly and allow it to dig down to the desired depth before starting the tractor into motion. 1 A WARNING For your personal safety, never attempt to operate the rotary tiller on steep slopes. Always till up the face of slopes, and never across the face. Avoid tilling downhill on inclines as the tiller may push the tractor faster than normal speeds. Never operate the rotary tiller on slopes greater than 27 percent (15 degrees)._______ 5 TILLING PATTERNS Determine the best pattern before you start. Consider the size and shape of the area to be tilled. The locations of fences or building can also affect the pattern. Usually, it is best to drive back and forth the long direction of the area. By making fewer turns, you can get the job done faster. However, after each pass, you can also back the tractor up after raising and disengaging the tiller. Whenever possible, plan your pattern so the previously tilled soil is to the right of the tractor. Otherwise, the chain case on the right side of the tiller may ride on the soil surface, reducing tilling depth or creating drag that causes wheel spinning. For fine seedbed soil, till the area in one direction, then till again at right angles. 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 corn, as an example, is 2 or 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. This 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 (A, figure 6). Make this adjustment as follows: NOTE If skid shoes plow soft soil so much that they stop tractor, they can be removed completely. They can also be removed to obtain deeper tilling depth (6 to 7 inches). 1. Stop tractor, set parking brake, and be sure the tractor PTO lever is in disengaged position. 2. Raise the 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 and down to desired height. Then reinstall pin and spring clip to secure skid shoe. Be sure both skid shoes are set to same height. A. Skid Shoe B. Pin and Spring Clip 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 and drive shaft, and thereby cause equipment damage. 6 Normal Care LUBRICATION The tiller should be lubricated as follows before first use and then every 8 hours of operation or annually. 1. Apply 2 or 3 shots of grease to grease fitting on each side (figure 7) of tines, on the chain cover (figure 8) and on the shaft from chain drive (figure 9). 2. Apply 2 or 3 shots of grease on each journal of PTO shaft, and grease fitting in the telescoping portion of PTO shaft. 3. Also, apply 2 or 3 drops of oil to pivot points, such as shown in figure 8. 4. Check oil leve^n right angle gear box by removing plug on4epfDil should be up to bottom of hole.

Touch up painted areas as needed. 7 Troubleshooting and Service TROUBLESHOOTING PROCEDURES Troubleshooting procedures are provided in figure 10. To use these procedures, first locate the problem description that best describes the touble 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. ^WARNING For your safety, do not try to adjust or repair the tracto...
