Deck Leveling Front To Back
Refer to Figure 3-6 on page 33:
Rear lift mechanism for Semi-Mount units can be either a
ratchet jack (#1) or hydraulic cylinder (#2). Adjust rear lift
mechanism to change the levelness from front to back.
1. Place a spirit level or other suitable leveling device on
one of the main deck channels to check deck profile.
Deck profile should be slightly higher at the back than
at the front.
Refer to Figure 3-7:
2. Raise or lower deck rear with ratchet jack (#1) or
hydraulic cylinder (#2) as follows:
Ratchet Jack Instructions
a. Raise or lower deck rear with ratchet jack (#1) by
setting mechanism in the jack handle.
b. Pump jack handle to raise or lower deck rear until
deck is slightly higher at the back than at the front.
c. If ratchet jack is working opposite of what is
needed, reset mechanism in jack handle and
return to pumping the jack handle.
Hydraulic Cylinder Instructions
a. Stroke control spacers (#3) are included with
hydraulic cylinder (#2). They consist of cast
aluminum halves with spring clips to hold the two
halves together.
b. With tractor hydraulics, extend hydraulic cylinder
to free up space on the cylinder rod.
c. Remove all stroke control spacers (#3) from
cylinder rod by spreading spacers apart at the
break line.
d. Retract or extend hydraulic cylinder until deck
profile is slightly higher at the back.
e. Select required size and number of stroke control
spacers (#3) that will fill the exposed cylinder rod.
The following spacers are available.
• Two 1" spacers
• One 1 1/4" spacer
• One 1 1/2" spacer
• One 1 3/4" spacer
NOTE: The cutter cuts most efficiently if the front of
the cutter is slightly lower than the back.
NOTE: Removing stroke control spacers lowers the
deck rear and adding spacers raises the deck rear.
f. Return to the tractor and raise Rotary Cutter up.
Install selected size and number of stroke control
spacers on the cylinder rod.
g. Retract hydraulic cylinder until stroke control
spacers are supporting the cutter weight.
h. Recheck deck profile. If needed, adjust size and
quantity of stroke control spacers until correct
deck profile is achieved.
i. Unused stroke control spacers may be stored on
hydraulic hose (#4) near the hydraulic cylinder.
3. Recheck cutting height. If required, repeat
“Cutting Height Adjustment” instructions on
page 33 and “Deck Leveling Front To Back”
instructions on this page.
