10.
Install the drain plugs and torque to 22 to 27
N∙m (16 to 20 ft-lb).
11.
Loosen the vent plug in each transmission so
that it is loose and wobbles
Note:
This allows air to escape the hydraulic
system as you add hydraulic fluid.

12.
Slowly add fluid to the hydraulic tank until it
starts to come out 1 of the vent plugs.
Important:
Use the fluid specified in
Hydraulic System Specifications (page 44)
equivalent. Other fluids could cause system
damage.
Important:
Monitor the level of fluid in the
hydraulic tank so that you do not overfill it.
13.
Tighten the vent plugs.
14.
Install the hydraulic-tank cap.
15.
Install the fuel tank.
16.
Start the engine and let it run for about 2 minutes
to purge air from the system.
17.
Shut off the engine and check for leaks.
Note:
If 1 or both wheels do not drive, refer to
Bleeding the Hydraulic System (page

Bleeding the Hydraulic
System
The traction system is self-bleeding, however, it may
be necessary to bleed the system if fluid is changed
or after work is performed on the system.
1.
Park the machine on a level surface, disengage
the PTO, and engage the parking brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Raise the rear of the machine onto jack stands
high enough to raise the drive wheels off the
ground.
4.
Start the engine and move the throttle control to
the idle position.
Note:
If the drive wheel does not rotate, assist
the purging of the system by carefully rotating
the tire in the forward direction.
5.
Check the hydraulic fluid level as it drops, and
add fluid as required to maintain the proper level.
6.
Repeat this procedure for the opposite wheel.
