Adjusting the Carrier Frame
(Groundsmaster 3500 only)
The front and rear cutting decks require different mounting
positions.
The front cutting deck has two mounting positions
depending on what height-of-cut and degree of deck
rotation is desired. The rear cutting deck has one mounting
position for proper alignment with the sidewinder under
frame.
Front Cutting Decks
1. For heights of cut in the 3/4 to 3 inch range, the front
carrier frames should be mounted in the lower front
mounting holes (Fig. 1).
Note: This permits more up travel of the cutting decks
relative to tractor when approaching quick uphill changes
in terrain. It does however limit the clearance of the
chamber to carrier when cresting sharp knolls.
2. For heights of cut in the 2–1/2 to 4 inch range, the front
carrier frames should be mounted in the upper front
mounting holes (Fig. 1).
Rear Cutting Decks
For all heights of cut, the rear cutting deck should be
mounted in the rear mounting holes (Fig. 1).

Note: This increases the chamber to carrier clearance due
to the higher position of the cutting chamber, but will cause
the cutting deck to reach their maximum up travel sooner.
