OWNER SERVICE
A WARNING Before servicing, adjusting, repairing or unplugging, stop tractor engine, place all controls in neutral, set park brake, remove ignition key, and wait for all moving parts to stop. Keep all persons away from operator control area while performing adjustments, service, or maintenance.
mower to transfer its weight to the jack stands, but do not raise the rear wheels off of the ground. When blocking, you must consider overall stability of the unit. Just placing jack stands under the unit will not ensure your safety. The working surface must be level and solid to support the weight on the jack stands. Ensure jack stands are stable both top and bottom, and mower is approximately level. With full mower weight lowered on jack stands, test blocking stability before working underneath mower.
A CAUTION Your dealer can supply original equipment hydraulic accessories and repair parts. Substitute parts may not meet original equipment specifications and may be dangerous. Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate. The information in this section is written for operators who possess basic mechanical skills. Should you need help, your dealer has trained service technicians available. For your protection, read and follow all safety information in this manual.
BLOCKING METHODS Jack stands, with a load rating of 1,000 pounds or more, are the only approved blocking device for this mower. A minimum of four jack stands, located under the mower as shown in Figure 8, must be installed before working underneath this unit. Do not position jack stands under wheels, axles, or wheel supports because these components can rotate. Do not work underneath unless it is properly attached to tractor (see Operation Section), the brakes set, key removed, and the mower blocked securely. The mounted unit will be anchored to minimize side to side and front to rear movement. The pull-type unit will be anchored front to rear. For the mounted unit, tighten tractor lower 3-point arm anti-sway mechanisms to prevent side to side movement. For the pull-type unit, raise mower with the standard ratchet adjustment link or the optional hydraulic cylinder. When the optional hydraulic cylinder is installed the standard equipment transport bar must be pinned in the raised position. With either the ratchet adjustment link or the optional hydraulic cylinder, lower

LUBRICATION INFORMATION (FIGURE 9) Figure 9 shows the lubrication points. The accompanying chart gives the frequency of lubrication in operating hours, based on normal conditions. Severe or unusual conditions may require more frequent lubrication. Do not let excess grease collect on or around parts, particularly when operating in sandy areas. Use SAE 90W gear lube in gearbox. Check gearbox daily for evidence of leakage at both seals and the gasket between the housing and cover. If leakage is noted, repair immediately. There may be a small amount of lube emitted from the vent plug; this is not considered leakage. Check the gearbox every day using the dipstick. Oil level is to be up to the ring but not over. Overfilling the gearbox will cause the excess gear lube to blow out vent plug. The gear lube could then ruin the belt. Use a lithium grease of No. 2 consistency with a MOLY (molybdenum disulfide) additive for all locations. Be sure to clean fittings thoroughly before attaching grease gun. When applied according to the lubrication chart, one good pump of most guns is sufficient. Do not overgrease. Daily lubrication of the driveline slip joint is necessary. Failure to maintain proper lubrication can result in
