Correcting Cutting Unit Mismatch - Toro Groundsmaster 200 Series Operator's Manual

require minimal power from the engine. By contrast a
blade that is higher at the ends than the center, or if
cutting edge is higher than the heel, the blade is bent or
warped and must be replaced.
5. Install the blade—sail facing toward the cutting
unit—with the anti-scalp cup and blade bolt. Tighten
the blade bolt to 85–110 ft.-lb. (115–149 N m).
Correcting Cutting Unit
Mismatch
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 3 foot long (1 m) carpenters level, find a level
surface on the shop floor.
2. Raise the height-of-cut to the highest position; refer to
Adjusting the Height-Of-Cut, page 15.
3. Lower the cutting unit onto a flat surface. Remove the
covers from the top of the cutting unit.
4. Loosen the flange nut securing the idler pulley to
release the belt tension.
5. Rotate the blades until the ends face forward and
backward. Measure from the floor to the front tip of the
cutting edge and 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 1/8 in. (3 mm). If the dimension
exceeds 1/8 in. (3 mm), 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
3/8 in. (10 mm) lower than the outer blades. If the
center blade is more than 3/8 in. (10 mm) lower than the
outer blades, proceed to step 7 and add shims between
the spindle housing and bottom of the cutting unit.
7. Remove the capscrews, 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
bottom of the cutting unit. Continue to check the
alignment of the blades and add shims until the tips of
blades are within the required dimension.
Important
Do not use more than 3 shims at any one
hole location. Use a decreasing numbers of shims in
adjacent holes if more than one shim is added to any one
hole location.
8. Readjust the idler pulley and install the belt covers.
