Checking And Correcting Mismatch Of Blades; Replacing The Drive Belt - Toro Groundsmaster 3200 Series Operator's Manual

Note:
Remove the blades and sharpen them
on a grinder. After sharpening the cutting edges,
install the blade with the anti-scalp cup and
blade bolt; refer to
the Cutting Unit Blade(s) (page
Checking and Correcting
Mismatch of Blades
If there is mismatch between the blades, the grass will
appear streaked when it is cut. This problem can be
corrected by making sure that the blades are straight
and all of the blades are cutting on the same plane.
1. Using a 1 m (3 ft) long carpenter's level, find a
level surface on the shop floor.
2. Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
3. Raise the height of cut to the highest position;
refer to Adjusting the Height of Cut (page
4. Remove the covers from the top of the cutting
unit.
5. Rotate the blades until the ends face forward
and backward. Measure from the floor to the
front tip of the cutting edge. Remember this
dimension. Then rotate the same blade so that
the opposite end is forward, and measure again.
The difference between the dimensions must
not exceed 3 mm (1/8 inch). If the dimension
exceeds 3 mm (1/8 inch), replace the blade
because it is bent. Make sure to measure all of
the blades.
6. Compare the measurements of the outer blades
with the center blade. The center blade must not
be more than 10 mm (3/8 inch) lower than the
outer blades. If the center blade is more than
10 mm (3/8 inch) lower than the outer blades,
proceed to step 7
spindle housing and the bottom of the cutting
unit.
7. Remove the bolts, flat washers, lock washers,
and nuts from the outer spindle in the area
where the shims must be added. To raise or
lower the blade, add a shim, Part No. 3256-24,
between the spindle housing and the bottom of
the cutting unit. Continue to check the alignment
of the blades and add shims until the tips of the
blades are within the required dimension.
Important:
Do not use more than three
shims at any one hole location. Use
decreasing numbers of shims in adjacent
holes if more than one shim is added to any
one hole location.
8. Install the belt covers.

Replacing the Drive Belt

The blade drive belt, tensioned by the spring-loaded
idler pulley, is very durable. However, after many
hours of use, the belt will show signs of wear. Signs
of a worn belt are squealing when belt is rotating,
blades slipping when cutting grass, frayed edges,
burn marks, and cracks. Replace the belt if any of
these conditions occur.
1. Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
2. Remove the belt covers from the top of the
cutting unit and set the covers aside.
3. Using a torque wrench or similar tool, move the
idler pulley
to release the belt tension and allow the belt to
be slipped off the gearbox pulley.

4. Remove the old belt from around the spindle
pulleys and idler pulley.
5. Using a torque wrench or similar tool to hold
the idler pulley, route the new belt around the
spindle pulleys and idler-pulley assembly as
