If you are going to adjust the control levers forward or
5.
rearward, proceed to the next step. If not, fully tighten the
flange lock nut.
To adjust the drive control levers forward or rearward, proceed as
follows:
If not already loose, loosen the flange lock nut and rotate the
1.
control lever either forward or rearward to the desired
position. See Figure 6-5.
NOTE:
If the control lever is too tight to move, slightly
loosen the hex insert flange lock nut and shoulder screw at
the bottom of the control lever.
Tighten the flange lock nut to fix the control lever in the
2.
adjusted position
Repeat the above procedure to adjust the other control
3.
lever into the same position. Adjust so that both levers are
even with each other when in the neutral position.
Leveling the Mower Deck
When correctly adjusted the mower deck should be level side to
side, and the front of the deck should be approximately 1⁄4 inch
lower than the rear of deck.
NOTE:
Check the tractor’s tire pressure before performing any
deck leveling adjustments. See the tire side wall for proper
inflation pressures.
Side to Side Leveling
If the cutting deck appears to be mowing unevenly, a side to side
adjustment can be performed. Adjust if necessary as follows:
With the tractor parked on a firm, level surface, place the deck lift
1.
handle in the top notch (highest position) and rotate both
blades so that they are perpendicular to the tractor frame..
Lower the deck to the middle height position.
2.
Measure the distance from the outside left blade tip to the
3.
ground and the distance from the outside right blade tip to
the ground. The measurements should be equal. If they’re
not, proceed to the next step.
Comparing the two measurements, determine whether the right
4.
side of the deck must be raised or lowered.
