Figure 40. Orient Blades Front-to-Back
Front To Back Leveling
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. See CHECK TIRE PRESSURE.
1. Turn the blades front-to-back as shown in Figure 40.
Measure the distance from the ground to front tip of
center blade, and from ground to rear tips of left hand
and right hand blades (see Figure 40). Front tips
should be 1/8"-1/4" (3-6 mm) higher than rear tips. If
not, proceed to step 2.
2. The front mower hitch rod (A, Figure 41) is used to
adjust front-to-back leveling. To raise or lower the
front of mower deck, loosen the two rear jam nuts (B)
on both sides of the hitch rod (A). Adjust the front jam
nuts (C) on both sides of the hitch rod (A) to adjust
the deck level. When adjusted correctly, tighten the
rear jam nuts (B) to lock hitch rod in place.
MOWER BELT REPLACEMENT
1. Park the rider on a level surface. Disengage the PTO,
turn off the engine, set the ground speed control
levers to START/PARK, and set the parking brake
lever to ENGAGE. Remove the key.
2. Use the idler pulley arm (C, Figure 42) to release belt
tension and remove the mower belt (A) from the PTO
pulley (E).
3. Remove the belt from the remaining deck pulleys.
NOTE: It is not necessary to remove the mower deck.
4. Install the new belt (A) as shown in Figure 42.
