Rear Spacers
The number of rear spacers determines the
aggressiveness of cut for the cutting unit. For a given
height of cut, adding spacers below the side-plate
mounting flange increases the aggressiveness of the
cutting unit. All cutting units on a given machine must
be set to the same aggressiveness of cut (number
of rear spacers, Toro Part No. 106-3925); otherwise,
the after-cut appearance could be negatively affected
(Figure 19).
Chain Links
The location at which the lift-arm chain is attached
determines the pitch angle of the rear roller
