3 Assembly & Set-Up Contents of Carton • Tiller (1) • Handlebar Support (1) • Handlebar Assembly (1) • Hardware Pack (1) • Wheels/Tines PTO Lever (1) • Operator’s Manual (1) • Engine Operator’s Manual (1) WARNING! To prevent personal injury or property damage, do not start the engine until all assembly steps are complete and you have read and understand the safety and operating instructions in this manual. 1.
3. Connect the tiller’s main harness connection to the neutral safety switch receptacle. See Figure 3-5. 3. Slide the plates at the end of the Wheels/ Tines/PTO Lever over the yoke plates. See Figure 3-7. To aid in the next step, insert a screw temporarily into the forward most holes of the yoke plates and the lever. 6. Wheels/Tines/ PTO Drive Lever Pull the Wheels/Tines/PTO Lever back to align the forward most holes in the yoke plate with the holes in the lever plates.
Engine Throttle Lever and Cable For shipping purposes, the throttle cable, together with the throttle lever, is wound around the engine. Carefully unwind the cable. If the throttle control label is covered with a clear protective coating, peel it off. WARNING! To avoid electric shock from a short circuit (electric start tillers only), never allow the throttle cable to touch the battery. Route the cable below the battery, on the outside of the battery holder.
4 Controls & Operation WARNING! Never run the engine indoors or in an enclosed, poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas. Avoid engine muffler and nearby areas. Temperatures in these areas may exceed 150° F. Engine Throttle Lever Handlebar Height Adjustment Lever NOTE: After the first two hours of operation, perform the maintenance procedures shown in the Maintenance Schedule in the Maintenance & Adjustments Section of this manual.
8. 9. If equipped with an electric start system, turn the key to START position to crank the engine then release when the engine starts. If the engine does not start right away, do not hold the key at START for more than a few seconds. Release then try again after a short pause. Damage to the starter motor can occur if it is cranked more than 15 seconds per minute. If the engine does not start after a number of tries, refer to the Engine Operator’s Manual for specific instructions. 10.
Stopping Reverse Motion 3. Release the Wheels/Tines/PTO Drive Lever — the lever automatically returns to the NEUTRAL position. This stops the wheels immediately. The Forward Interlock Levers will not stop REVERSE motion. At the end of a row, move the Wheels/Tines/ PTO Drive Lever to NEUTRAL position and reduce the engine speed. 4. Move the Tines/PTO Clutch Lever into the DISENGAGE position. 5. Resume forward operation, and lift the handlebars until the tines are off the ground. Refer to Figure 4-5.
NOTE: If extra belt slack is needed to move the belt, just raise the Wheels/Tines/PTO Drive Lever up into REVERSE. This lowers the engine pulley, and creates more slack. Changing Belt From Low Range to High Range 1. 2. To avoid personal injury, shut off the engine, let all moving parts come to a complete stop, then disconnect the spark plug wire from the spark plug and move the wire away from the spark plug before making any adjustments. Wait for the engine and muffler to cool down.
• When cultivating — breaking up the surface soil around plants to help destroy weeds — use very shallow depth settings to prevent injury to plants whose roots often grow close to the surface. If needed, lift up on the handlebars slightly to prevent the tines from digging too deeply. Cultivating on a regular basis not only eliminates weeds, it also loosens and aerates the soil for better moisture absorption and faster plant growth.
• Move the belt into LOW belt range and the Wheel Speed Gear Lever to SLOW position. As in terrace gardening, start at the top of the slope and overlap the first pass by half the width of the tiller. For added stability, keep the uphill wheel in the soft, newly tilled soil. Each succeeding terraced area is started by walking below the terrace you are preparing. See Figure 4-17. • Pushing over (but not uprooting) cornstalks will often make it easier for your tiller to chop up the stalks.
7. Loosen the two swing-out bolts that connect the power transmission to the tine attachment. See Figure 4-21. 10. The guide pin on the power unit will slide out of the guide hole in the tine attachment See Figure 4-24. Guide Pin 4. If the engine is stopped, move Wheel Speed Lever to FREEWHEEL, and manually push the tiller. Loading & Unloading the Tiller The following provides information on tiller loading, unloading, and requirements before loading and unloading the tiller.
5 Service Maintenance Schedule After 2-hour Break-In Before Each Use Every 10 Hours Every 25 Hours Every 30 Hours Refer to Engine Manual P P Check Engine Oil Level Clean Engine Cooling System P P P Test Operation of FWD. Interlock Safety System FWD.
3. After cleaning away any debris and removing old grease, apply fresh grease to the wheel shaft before re-installing the wheels. Rear Bearing Cap Screws Transmission Gear Oil • Checking for oil leaks Hardware Check for loose or missing hardware every ten (10) operating hours. Failure to tighten or replace fasteners can cause poor performance, equipment damage or oil leakage. Most hardware on your tiller is visible. Pay particular attention to hardware listed below.
4. Use a 3⁄8” wrench to remove the oil level check plug on the left side of the transmission housing. See Figure 5-6. on the back of the tine shield. See Figure 5-7. Wipe it clean with a rag. 7. 8. Oil Level Check Plug 9. Hold the dipstick so its markings face to the rear of tiller. Lower it straight down into the sump hole to touch the drive shaft inside. See Figure 5-7. Don’t force or try to thread it back in; an incorrect reading will result. Remove the dipstick and check the oil level.
3. Slowly add gear oil in the dipstick hole. Add 1⁄2-ounce at a time to avoid overfilling. It takes about 12-1⁄2 ounces. 3. 4. Take dipstick readings frequently. Stop when oil reaches “Cold” range marking on dipstick. Replace dipstick securely. Lubrication Draining and Filling the Tine Attachment Transmission 1. The tine attachment transmission is not equipped with an oil drain plug.
2. Move the Wheels/Tines/PTO Drive Lever fully down to the FORWARD position. The clutch roller at the bottom of the lever should be positioned underneath the belt adjustment block. See Figure 5-13. Don’t let the clutch roller move during the next few steps. If it moves, you’ll get a false belt tension reading. 2. Move the Wheels/Tines/PTO Drive Lever to NEUTRAL position.
Checking and Adjusting the Reverse Drive System 3. When the Wheels/Tines/PTO Drive Lever is moved up into REVERSE, the engine and engine mount move down to press on the reverse adjustment bolt. See Figure 5-19. Switch Body Adjustment Bolt Use your left hand to hold the Wheels/Tines/ PTO Drive Lever up in REVERSE, while briefly pulling out the engine recoil starter. The reverse disc should turn the lower pulley. See Figure 5-21.
center of the belt with your finger. Throttle Cable The throttle lever settings are factory adjusted, so unnecessary adjustments should not be made. However, if the engine does not start or stop, or respond immediately to various throttle lever settings, then adjustments may be necessary. Please refer to the Engine Operator’s Manual supplied with your tiller for specific adjustment instructions. 3. Ignition System Lower Pulley Your engine is equipped with an electronic ignition.
1. Move Wheels/Tines/PTO Drive Lever in NEUTRAL position. 2. Wedge a 5⁄16”-thick board between the top of the engine pulley and the cast iron housing next to it. This immobilizes the pulley. Avoid contacting the reverse disc. 3. Use a 9⁄16” wrench to loosen the mounting bolt shown in Figure 5-30. Remember to immobilize the pulley with the wood wedge while loosening the bolt. If necessary, pry the disc from the pulley with the tip of a screwdriver. Back the bolt out as far as possible.
6 Troubleshooting Problem Wheels and tines do not turn Cause Remedy 1. Mis-adjusted drive belt and/or reverse disc 1. See Maintenance & Adjustments Section 2. Loose bolt on transmission drive pulley 2. Tighten bolt 3. Worn worm gears 3. See authorized service dealer Wheels and tines turn on top of ground, but stop or hesitate in soil 1. Loose drive belt 1. Adjust drive belt (See Maintenance & Adjustments Section) 2. Loose bolt on transmission drive pulley 2.
