Cutting Deck Position Switches
Three (3) cutting deck position switches are used on the
Groundsmaster 4000--D and 4010--D. These switches
are located on the traction unit frame (Figs. 59 and 60).
The position switches are powered proximity switches
that incorporate an internal reed switch and a LED. The
deck position switches are used as inputs for the
TEC--5001 controller to prevent deck operation when a
cutting deck is raised. The switch sensing plates are at-
tached to the cutting deck lift arms. The position
switches for front and side decks are different.
The single front cutting deck position switch is a normal-
ly closed switch. When the front cutting deck is lowered,
thesensing plateontheliftarmisawayfromtheposition
switch sotheswitch is inits normally closed state.When
the front cutting deck is raised, the sensing plate is
moved near the position switch and the switch opens.

The two (2) side cutting deck position switches are nor-
mally open switches. When a side cutting deck is low-
ered,the sensing plate onthe liftarm isnear theposition
switch and the switch closes. When a side cutting deck
israised,thesensingplateismovedawayfromtheposi-
tion switch so the switch is in its normally open state.

Testing
1.
The cutting deck position switches and their circuit
wiring should be tested as a TEC--5001 input with the
Diagnostic Display (see Diagnostic Display in the Trou-
bleshooting section of this chapter). If the Diagnostic
Displayverifiesthatthepositionswitchesandcircuitwir-
ing are functioning correctly, no further switch testing is
necessary. If, however, the Display determines that a
positionswitchandcircuitwiringarenotfunctioningcor-
rectly, proceed with test.

3.
Turn ignition switch to the ON position (do not start
engine) and check LED on cable end of position
switches (Fig. 61). Switch LED should be illuminated
when the cutting decks are fully lowered.

Start engine, fully raise cutting decks and then stop
engine. Then, turn ignition switch to the ON position (do
notstartengine)andcheckLEDoncableendofposition

If a position switch LED did not function correctly:
A. Position cutting deck so sensing plate on the lift
arm is near the position switch (front cutting deck
raised and side cutting decks lowered).
