WARNING: Always lower the hydraulic lift and equipment before stopping the unit. ight transfer valve The weight transfer valve is used to transfer the front ent weight to the tractor unit to reduce equipment on turf and prevent damage and improve front drive eel traction. Figure 3-11 The weight transfer valve should be used according to the ng procedures; With the engine running, push the hydraulic lift lever forward to the floating position. Turn the adjusting knob clockwise until the mower or ther equipment lifts off the ground. Turn the adjusting knob counter-clockwise slowly until he mower deck front gauge wheels or other equipment ust touches the ground, then turn the knob counterclockwise 1/4 turn more. Operate the unit over uneven terrain at desired travel speed and observe the mower deck’s front gauge wheels. If the wheels or equipment do not follow round contour, the operation will be affected. To correct this condition, turn the knob 1/4 turn clockwise at a time until the mower deck’s front gauge wheels follow the ground contour. Auxiliary hydraulic valve kit (optional) Auxiliary Hydraulic Valve kit is available from your Hustler Dealer, as an option. When using the auxiliary valve, turning, a loss of steering control will result. 3-10 109627_0910 109627_0910 3-11 the lift control lever must remain in neutral. Figure 3-17 and Figure 3-18 This kit includes control valves, hoses and quick connect couplers for supplying hydraulics power to optional attachments. When not in use, the coupler dust covers must be in place to prevent contamination. Always replace them immediately if damaged or lost. Note the hydraulic circuit connectors called out in Figure 3-18. Once connected, the operator has control of the attachment’s hydraulic cylinder by means of the valve control levers. If stroking the valve lever produces the wrong cylinder movement (up-down, right-left, etc.), reverse the attachment hoses at the quick connect couplers. Use of the valve control lever varies with each attachment and is described in more detail in the operating instructions provided with the attachment. WARNING: Never attempt to connect or disconnect the couplers with the hydraulics engaged and the system oil under pressure. Rear counter-balance weights WARNING: Improper operation on slopes can cause injury. Install rear counter-balance weights, when the attachment is installed, to increase stability. Use extreme care when operating on slopes. Rear counter-balance weights are required to improve stability, steering and traction. They also reduce tire lift off when attachments are raised, operated on slopes or during an abrupt stop. Refer to Figure 3-19 for weight attachment. Refer to the attachment’s owner’s manual for the proper weight amount and weight part number. ROPS (Roll Over Protective Structure) A Roll Over Protective Structure (ROPS) and seat belt are standard equipment. Do not remove the ROPS and seat belt. ROPS when used with seat belt is effective in reducing injuries during unit overturn accidents. Overturning the unit without ROPS can result in serious injury or death. NOTE: Inspect the ROPS after the first 20 hours of operation. Following the initial inspection, check the ROPS after every 500 hours of operation or every six months, whichever comes first. Figure 3-20 1. Check the torque of the ROPS mounting bolts. Tighten the bolts to the correct torque of 72 ft.-lbs. (97 Nm) if necessary. Figure 3-21 2. Inspect the operator’s seat and the mounting parts for the seat belt. Tighten the bolts to the correct torque of 72 ft.-lbs. (50.0 Nm) if necessary and replace parts that show wear or damage. The two-post ROPS can be pivoted down by removing the right and left retaining rings and pulling out on the pins so that the machine can operate under low hanging tree limbs or other obstructions.

IMPORTANT: if the ROPS is folded down. In this case, the seat belt should never be worn. WARNING: To minimize chance of injury or death from rollover: keep ROPS in the raised and locked position and use the seat belt. Never operate machine on a slope with the ROPS folded down (lowered position). There is no roll over protection when the ROPS is in the lowered position. Lower the ROPS only when absolutely necessary. Drive slowly and carefully. Raise the ROPS as soon as clearance permits. Read and follow slope operation instructions and warnings. Do not wear seat belt when the ROPS is in the lowered position. WARNING: Always pull from the tractor hitch. Do not attach chains or ropes to the ROPS for pulling purposes,as the machine can tip backwards. ways fasten seat belt during operation of the machine th ROPS in “raised/up” position.
