6.4 How to Move the Mower if the Engine Won’t Start

Rotate both of the hydro bypass valves on the side of each hydraulic pump about ½ turn counterclockwise. It

is important not to over tighten these. Damage may occur to the pump if this valve is over tightened.

6.5 Hydraulic System

Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting

into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic parts are

disconnected or removed or when the oil is changed, air must be bled from the system. If air is entrained in

the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur. First, make sure

the oil level in the reservoir is correct. Use fully synthetic oil: Mobil1 15W-50. Lift the mower so that the rear

wheels are off the ground. Be careful to support the mower so that it will not fall or tip while the system is bled

of air. With the bypass valves open and the engine running, slowly move the control levers back and forth five

or six times. Now close the bypass valves and with the engine running, slowly move the control levers back

and forth five or six times. It may be necessary to repeat the above steps until all the air is purged and the

rear wheels are turning at normal speed. After purging is complete, adjust the oil level in the reservoir if

necessary.
