Mower Drive Belt Tension Adjustment -
All Models
If the mower belt slips or fails to drive, the
mower belt tension may need adjustment.
To check, proceed as follows.
1. Place the mower in high cut, using
height control lever. Place the PTO
lever in engaged position.
2. Measure the distance between the PTO
rod guide (A, figure 34) and the set
collar (B). For the 36" mower the mea¬
surement should be 3/8 to 1/2 inch (10
to 13 mm). For the 42" mower the mea¬
surement should be one inch (25.4 mm).
3. Place the PTO lever in disengaged
position.
4. Loosen the setscrew in the set collar (B).
Move the rod (G) forward to increase
gap, or backward to decrease gap.
Retighten the setscrew.
5. Repeat the adjustment as necessary
until the distance measures as described
in step 2 with the PTO lever in engaged
position.
6. Check the adjustments of the PTO
pulley belt stops and the mower belt
stops. On 42" and 48" mowers, check
Mower Brake Adjustment (see page
32.)
Adjust the left-hand belt stop (figure 34) and
the right-hand belt stop (figure 35 A or 35B)
to obtain 1/16 in (1.5 mm) from belt with
PTO engaged. Loosen capscrew to adjust. If
1/16 inch cannot be obtained without
touching pulley, place as close as possible.
