Cutting Unit Down Limit Switch - Toro Reelmaster 5010- H Service Manual

Cutting Unit Down Limit Switch

The cutting unit down limit switch is a normally open
proximity switch that closes when the front, outside cut-
ting units are in the turn- around position. The down limit
switch is attached to a frame bracket inside the front,
right lift arm pivot tube. A bracket on the front, right lift
arm acts as the sensing plate for the down limit switch
(Fig. 29).
Adjustment
The down limit switch should be secured to the switch
bracket at the midpoint of the bracket mounting slots.
NOTE: The vertical location of the down limit switch on
the switch bracket will determine the turn- around posi-
tion of the front, outside cutting units (cutting units #4
and #5). Raising the switch on the bracket will allow a
lower turn- around position of the cutting units. Lowering
the switch on the bracket will allow a higher turn- around
position of the cutting units.
The distance between the down limit switch and the
sensing plate on lift arm should be from 0.094" to 0.100"
(2.4 to 2.5 mm). If distance is incorrect, loosen jam nuts
that secure down limit switch to machine frame. Position
switch with jam nuts to allow correct clearance between
switch and sensing plate. Jam nuts should be torqued
from 162 to 198 in- lb (18.4 to 22.4 N- m). After jam nuts
are tightened, make sure that clearance has not
changed.
After adjustment to the down limit switch, use the Info-
Center Display (see Diagnostics Screen (PTO item) in
the InfoCenter Display section of this chapter) to verify
that down limit switch and circuit wiring are functioning
correctly.
