Be sure tractor reservoir is filled properly before 
operating hydraulic cylinders. If tractor reservoir is low on 
hydraulic fluid, there is a chance of drawing air into the 
system causing jerky or uneven cylinder movements. 
The wing deck lift cylinder may be purged as follows:

Wing Fold Cylinders
1.

Start tractor and lower center deck until it is 
supported by stroke control spacers (#5) on hydraulic 
cylinder (#1). 

2.

Lower wing deck until it is resting on the ground.

3.

See “Tractor Shutdown Procedure” on page 14. 
Shut tractor down properly and move wing control 
levers back and forth to relieve all hydraulic pressure. 

4.

Slightly loosen hose fittings (#4) on wing folding 
cylinder (#3).

5.

Restart tractor and slowly activate tractor control 
lever to extend/retract folding cylinder (#3), and to 
purge trapped air from the hydraulic system.

6.

Shut tractor down properly, dismount, and tighten 
hose fittings (#4) on folding cylinder (#3). 

Deck Lift Cylinders
Deck lift cylinders are rephasing cylinders and self purge 
if tractor control lever is held in deck lift position for and 
extended period.

1.

Start tractor and slowly activate tractor control lift 
lever to extend hydraulic cylinders (#1 & #2).

2.

Once cylinders (#1 & #2) are fully extended, continue 
to hold control lever in the deck lift position to allow 
time for hydraulic oil and trapped air to make a 
complete circuit through the hydraulic system.

3.

With tractor control lever, lower and raise decks 
several times to verify all trapped air is removed and 
cylinders (#1 & #2) are operating smoothly.

4.

If needed, repeat steps 1 thru 3 until deck left 
cylinders operate smoothly.
