OWNER SERVICE
The information in this section is written for operators who possess basic mechanical skills. If you need help, your dealer has trained service technicians available. For your protection, read and follow the safety informa- tion in this manual.
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
CAUTION
If you do not understand any part of this manual and need assistance, see your dealer.
Always wear relatively tight and belted clothing to avoid entanglement in moving parts. Wear sturdy,
BLOCKING METHOD
Never go underneath equipment (lowered to the ground or raised) unless it is properly blocked and secured. Never place any part of the body under- neath equipment or between moveable parts even when the engine has been turned off. Hydraulic system leak down, hydraulic system failures, mechanical failures, or movement of control levers can cause equipment to drop or rotate unexpect- edly and cause severe injury or death. Follow Oper- ator's Manual instructions for working underneath and blocking requirements or have work done by a qualified dealer.
To minimize the potential hazards of working under- neath the cutter, follow these procedures:
1.Jackstands with a load rating of 1000 lbs. or more are the only approved blocking device for this cutter. Install a minimum of four jackstands (shown by Xs in Figure 12) under the cutter before working underneath unit.
Do not position jackstands under wheels, axles, or wheel supports. Components can rotate and cause cutter to fall.
2.Consider the overall stability of the blocked unit. Just placing jackstands underneath will not ensure your safety.
The working surface must be level and solid to support the weight on the jackstands. Make sure jackstands are stable, both top and bottom. Make sure cutter is approximately level.
3.With full cutter weight lowered onto jackstands, test blocking stability before working underneath.
4.If cutter is attached to tractor when blocking, set the brakes, remove key, and block cutter before working underneath.
5.Securely block rear tractor wheels, in front and behind. Tighten tractor lower
LUBRICATION
Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
See Figure 12 for lubrication points and frequency or lubrication based on normal operating conditions. Severe or unusual conditions may require more fre- quent lubrication.
Use a lithium grease of #2 consistency with a MOLY (molybdenum disulfide) additive for all locations unless otherwise noted. Be sure to clean fittings thoroughly before attaching grease gun. One good pump of most guns is sufficient when the lubrication schedule is fol- lowed.
Gearbox Lubrication
1.Use a high quality gear oil with a viscosity index of 80W or 90W and an API service rating of
2.Fill gearbox until oil runs out the the lower hole on back side of center gearbox or side hole on spindle gearboxs. Check gearboxs daily for evidence of leakage, and contact your dealer if leakage occurs.
Driveline Lubrication
1.Lubricate the driveline slip joint every eight operating hours. Failure to maintain proper lubrication could result in damage to
2.Lower cutter to ground, disconnect driveline from tractor PTO shaft, and slide halves apart but do not disconnect from each other.
3.Apply a bead of grease completely around male half where it meets female half. Slide drive halves over each other several times to distribute grease.
4.Grease side drive yoke where yoke attaches to side gearbox.
