PREPARING THE VEHICLE Preparing the tractor CAUTION: Avoid injury. Proper ballastings is required for safe operation of your tiller IMPORTANT: Refer to the tractor operator manual for proper ballasting information and tire inflation • A 540 rpm PTO • Refer to the tractor operator is manual for correct ballasting and tire pressure, depending on installed equipment. Park vehicle safety • • • • • • Stop vehicle on a lever surface, not on a slope. Disengage PTO. Engage the park brake. STOP the engine.
INSTALLING Locate driller pin in lower lift brackets holes (B). RT 1240-1250-1160-1160 H model. 2. Fasten each draft link to draft link brackets with drilled pins and quiklock pins (C). C B Locate driller pin in holes (B). RT 1260-1360 model. 2. Fasten each draft link to draft link brackets with drilled pins and quiklock pins (C). C B Locate driller pin in top holes (D) RT 1140-1150 model. E 3. Install center link (F) on tiller and fasten with drilled pin and quiklock pin (E).
INSTALLING 4. Install PTO shaft to tractor. IMPORTANT: Tiller MUST BE level front to rear. • Engage the cardan shaft and check that it is perfectly locked on the tractor PTO (G). Check that the guard (H) is free to turn and fix it with the relative latch. G H 5. Raise tiller. 6. Remove spring locking pin (K) from parking stand. 7. Slide parking stand (I) and way up on tiller bracket (J). 8. Fasten with spring locking pin (K). I 9. Level tiller (See Leveling Tiller in the Operating Tiller section). 10.
INSTALLING PTO shaft with shear pin (1140-1240 model) A The shear pin, inserted in the PTO shaft, is equipped with a safety bolt (A) that is set for an average force. Whenever unduly resistant obstacles cause the bolt to shear, it must be replaced by a new bolt, of the same size and material. If the bolt, inserted in hole (A), shears repeatedly, then we recommend inserting it in the hole (B).
INSTALLING Quick Coupler (optional) 1) Install hitch Quick Coupler (A) on the tractor (see tractor operator manual). D B D 2) Stop vehicle on a level surface, not on a slope, then moving back to the tractor until the Quick Coupler (A) is range with the (B) and (C) hitch points. A C C 3) Raise the Quick Coupler (A) and make sure that tiller’s hitch is in the right position (E). E CAUTION: Before you work around hitch: • STOP engine. • LOCK park brake. • FIRMLY block tiller on horizontal surface..
REMOVING Removing tiller 1. Raise tiller. 2. Put parking stand (A) in the DOWN position: Install spring locking pin (C) in order to secure parking stand (A) to the tiller bracket (B). 3. Lower tiller to the ground. C A B CAUTION: Before you work around hitch: • STOP engine. • LOCK park brake. • FIRMLY block tiller on horizontal surface. 4. Disconnect driveline from tractor by pulling back on coupler to release it from the LOCKED position. 5.
OPERATING Operate safely • Protect your hands when you inspect or unplug the tiller. You may need gloves or tools, such as a screwdriver or scraper. Be sure hardware is tight. Repair or replace damaged, badly worn, or missing parts. Be sure guards and shields are in good condition and fastened in place. Make any necessary adjustments before you operate. • Clear work area of objects that you do not want tilled into the ground or that might damage the tiller.
OPERATING Wear appropriate clothing • Wear close fitting clothing and safely equipment appropriate for the job. • Loud noise can cause impairment or loss of hearing, wear a suitable protective device such as earplugs. Stay clear of rotating drivelines Entanglement in rotating driveline can cause serious injury or death: • Wear close fitting clothing • Stop the engine and be sure PTO drivelines is stopped before getting near it. CAUTION: Before you work around hitch: • STOP engine. • LOCK park brake.
OPERATING Leveling tiller (front-to-rear) 1.Start the engine. 2.Lower the tiller to 25 mm (1 in.) off the ground. 3.Stop the engine. 4.Make sure the top of the tiller is LEVEL, or PARALLEL with the ground, front-to-rear. 5.Adjust level, if necessary. To adjust level: a. Start the engine. b. Lower the tiller to the ground. c. Stop the engine. d. Loosen jam nut (A). • Shorten the center link (B) to lower the front of the tiller. • Lengthen the center link (B) to raise the front of the tiller. e.
OPERATING 2. Lower leveling board to top of ground (C): • Tilled soil (D) will be fine and level. • Tractor speed will determine size of clods (E). C E 3. Raise leveling board (C): • Tilled soil (D) will be coarse and rough. • Tractor speed will determine size of clods (E). CAUTION: Before you work around hitch: • STOP engine. • LOCK park brake. • FIRMLY block tiller on horizontal surface. B C E D Adjustable offset The tiller unit can be shifted sideways in relation to the three-points hicth.
OPERATING Tilling tips Before You till: • Pick up rocks and foreign objects. • Mow tall weeds and grass to keep them from wrapping around tines or tine shaft. • Check tines. Loose, bent, broken, or missing tines reduce operating efficiency. If necessary, replace tines. Test the soil by squeezing it in your hand. If soil forms a ball, it is too wet to till. If soil does not compress easily or falls apart, it is ready to till. DO NOT till when soil is wet. Wet soil will stick to the tines and tine shaft.
SERVICE MACHINE SAFELY Practice safe maintenance • Understand service procedure before doing work. Keep area clean and dry. • Never lubricate, service, or adjust machine while it is moving. Keep safety devices in place and in working condition. Keep hardware tight. • To prevent from getting caught, keep hands, feet, clothing, jewelry, and long hair away from any moving parts. • Before servicing machine, lower it to the ground. Disengage all power and stop the vehicle engine.
SERVICE LUBRICATION Service lubrication WARNING: • Firmly block tiller on horizontal surface. • Always keep oils and greases well away from children’s reach. • Always thoroughly read the warnings and precautions indicated on the containers.
