To adjust 28" and 30" mowers (Figure 5):
1. Place height control lever in midnotch position,
depress spring clip and tighten yoke on front of unit

2. When tightening cap screw, hold mower clutch
lever so that front edge of lever is positioned in line
with rear edge of forward notch of quadrant.

load. Mower clutch lever (when tightening cap
screw) will move slightly to rear of this point when
tension is correct.
To adjust the 32" mower:
1. The 32" mower belt clutch rod should be adjusted
so the compressed spring length is from 5-1/4" to
5-3/8" (13.3 to 13.6 cm) when belt is engaged
(Figure 6).

mower clutch is positioned in line with rear edge of
forward notch of quadrant (as viewed through slot
in left side of cowl).
3. Full locked-in engagement should occur when
lever is positioned completely into front notch of
