If it becomes necessary to move the tractor when the engine is inoperative, the hydraulic pumps are equipped with bypass valves. Before moving the unit, turn bypass valves counter clockwise one-half to one revolution. The valve stems on each hydraulic pump are located near the top and are identified as a hex stud. The valve is located per Figure 3-7, 3-8 & 3-9.

The steering control levers must be placed in the neutral position, to release the park brakes, so that the tractor can be moved.

Do not tow the machine. Move it by hand or use a winch to load on a trailer for transporting.

When transporting on another vehicle, the tractor should be facing forward and it must be secured.

IMPORTANT: Always make certain the two bypass valves are returned to their operating position before running the tractor following repairs. (Fig. 3-7, 3-8 & 3-9)

ROPS

(Roll Over Protective Structure)

A Roll Over Protective Structure (ROPS) and seat belt is provided with the 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. Fig. 3-10

1.Check the torque of the ROPS mounting bolts. Tighten the bolts to the correct torques as shown below if necessary. Fig. 3-11, 3-12 & 3-13

2.Inspect the operator’s seat and the mounting parts for the seat belt. Tighten the bolts to the correct torque as shown below 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. Do not wear the seat belt when the ROPS is in the lowered position. Use the ROPS in the “folded” position only when it is absolutely necessary. Fig. 3-10

WARNING: Do not operate the mower with the ROPS folded (lowered position) as a standard operating mode. A folded ROPS does not provide rollover protection.
