LIFT LIMIT SWITCHES _____________________________________________________
The rotation of the cutting blades is controlled by limit
switches positioned on the mower frame near the lift
arms for each deck. When a deck is raised the switch
opens and automatically disengages the cutting blades.
As the deck is lowered, the switch closes and the blades
engage. If a swi tch fails, the cutting blades will not
engage when lowered.
To adjust limit switches:
1. Park mower on a level surface.
2. Start mower and raise or lower decks until the
highest point on the top corner of the deck reaches
the height shown in
Figure 3G
.
3. Shut OFF engine and remove key. Support decks
using blocks. This will prevent them from accidently
lowering while making adjustments.
4. Position switch so sensing area
(C)
on sw itch is
centered over leading edge
(A)
of activator plate on
lift arm.
5. Adjust gap between sensing area on s witch and
activator plate on lift arm to 1/16 - 1/8 i n. (1.5 - 3
mm). To adjust gap for front lift arm use shims
(D)
or
#10 flat washers
(B)
between switch and switch
mount.
Check operation of limit switches. Blades must stop
rotating as decks are raised above heights shown.
