There are several hydraulic valve solenoids on the
Groundsmaster 4100--D (Fig.32). Testingofthesesole-
noids can be done with the solenoid on the hydraulic
valve.
3. Install new solenoid if necessary. Torque solenoid
nut to 5 ft--lb (6.7 N--m). Over--tightening may damage
the solenoid or cause the cartridge valve tomalfunction.

nector to the solenoid.
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5
ohms or less). This resistance is due to the internal
1
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.

Make sure engine is off. Disconnect wire harness
connector from the solenoid (Fig. 33).

Measure resistance between the two (2) solenoid
connector terminals. The resistance for any solenoid
coil used on the Groundsmaster 4100--D should be
approximately 8.7 ohms.

At only 700mm wide the Mini Dumper is even at home on tight access
sites. No need to grunt, groan, and force the
mower about the yard. The US will be getting a revised 2011 Jeep Wrangler but the diesel option will not be offered in the United States.
