GENERAL OPERATION
Cam Follower Thrust Blocks – 1576
The forward thrust of the cutting head is carried by
the cam follower thrust blocks, which are mounted
on the cutting head frame. The thrust blocks act
upon cam followers which are mounted to the
cradle. It is essential to keep this assembly properly
adjusted to assure the longevity of the pivot bearings
of the floating head unit.
Adjust the thrust block against the cam follower with
the adjusting bolt until the cam roller cannot be
turned by hand. Turn the adjusting bolt two more
flats of the head (120 degrees). This assures that
the thrust forces act upon the cam rollers, and not
the pivot bearings. Tighten all locknuts and bolt, and
check regularly to assure that this unit is
operational.

Roller Adjustment
The roller supports the front end of the harvesting
unit, and also applies pressure to the sod
immediately ahead of the cutting blade. This roller
can be adjusted forward or backward on the frame
and should be set so that the vertical centerline of
the roller is 1 ½” (8” roller) or 2 ½” (10” roller) ahead
of the edge of a new cutter blade, when the blade is
at the maximum forward position of the cutting
stroke. The roller and blade must be parallel to each
other, to avoid sod that is thicker on one side.
In certain “Peat” or “Muck” soils, a distance of less
than specified above may be required for a proper
cutting action.
In “soft soils” or “excessive thatch” conditions, rolling
the sod just before cutting may result in easier
cutting, and a better quality (tighter) roll.
In “stoney ground” it is often advisable to move the
8” roller forward to provide more space between the
blade and roller for small stones to pass through.
This distance (on 8” rollers) may be increase up to 2”
or 2 ¼”. Too little distance between the roller and the
blade causes a “pinching action” resulting in longer
pieces of sod.
The roller should be centered between the side arms
of the cutting blade, so that the bolts on the cutting
blade do not strike the roller in operation.
