CuttingHeightAdjustment
The cutting height can be adjusted within two different
ranges. The lower cutting range is adjustable between
1-1/2" (3,8 cm) and 2-3/4" (6,9 cm). The upper cutting
range is adjustable between 2-3/4" (6,9 cm) and 4-1/2"
(11,5 cm).
Before adjusting the cutting height, you must first determine
the averagecutting height. Depending on the range you
plan to use, it may be necessaryto adjust which pulley the
deck drive belt runs in.
ToAdjust the CuttingRange:
1. Removethe mower deck guard (A, Figure6) to gain
access to the mower deck drive belt.
, ,WARNING
Use extremecautionwhen rotating the idler arm with
the breaker bar, due to the increasedtension in the
spring as the idler arm is being rotated, injury may
result if the breaker bar is prematurely released while
the spring is under tension.
2. Using a 1/2" breaker bar (A, Figure 7), placethe square
end in the square hole located on the end of the idler
arm (B). Carefully rotate the breaker bar CLOCKWISE,
which will relieve the tension on the belt exerted from
the idler arm.
3. Slide the drive belt over the edge of the Stationary idler
pulley (C). Carefully releasethe tension on the breaker
bar until the idler arm comes to a stop.
4. See Figure 8. If you are adjusting the cutting height
range between 1-1/2" (3,8 cm) and 2-3/4" (6,9 cm)
position the belt in the lower pulley on PTOclutch. If
you are adjusting the cutting height range between 2-
3/4" (6,9 cm) and 4.5" (11,5 cm) position the belt in the
upper pulley on the PTOclutch.
5. Carefully rotate the breaker bar CLOCKWISE and install
the drive belt on the stationary idler pulley. Carefully
releasethe tension on the breaker bar. The belt should
be routed exactly as shown in figure 9.
