Evaluating the PTO clutch

To evaluate a PTO clutch:
NOTE: most of the evaluation can be preformed
while the clutch is still mounted to the
engine.
1. Disconnect the harness from the PTO clutch.
2. Measure the clutch coil resistance:
2a. Set the meter to check ohms.
2b. Disconnect the harness from the PTO clutch.
NOTE: On tractors with the diode jumper, discon-
nect the jumper from the PTO clutch
2c. Measure clutch coil's resistance across the
clutch contacts. See Figure 8.54.
• If the meter reads below 2.70 ohms or above
2.98 ohms, the clutch has failed and needs to
be replaced.
• If the meter reads between 2.40 and 3.40 ohms, proceed to measuring clutch current draw.
3. By-pass the seat switch:
3a. Lift up the seat.
3b. Press in on the lower section of the seat until
the tabs on the seat switch extend out of the
switch.
3c. Clamp onto the tabs with a pair of spring
clamps.
