Measuring Clutch Current Draw
1. Disengage the PTO, set the parking brake, and
turn the ignition to OFF.
2. Disconnect the clutch wire connector.
3. Set the multimeter to check amps (10 amp scale).
4. Connect the positive meter lead to the tractor
terminal (1) of the clutch wire, Figure 231.
5. Connect the negative meter lead to the
corresponding wire terminal (3), Figure 231.
6. Connect a short jumper lead from terminal (2) to
(4), Figure 231.
7. Turn the ignition switch to the “RUN” position and
the PTO switch to the “ON” position.
8. If the meter reading is 3.5 amps or above, the
system is functioning properly. If the meter
reading is below 3.5 amps, check the electrical
system for problems (i.e., the battery, ignition
switch, PTO switch, or wiring harness may be
malfunctioning).

On 1999 and prior model 260 Lawn and Garden
Tractors, the air gap between the clutch plate and the
friction plate is adjustable. The 2000 and later model
PTO clutch is self-adjusting.
Note: The 2000 and later model 260 Series tractors
use a non-adjustable PTO clutch.
Setting the Air Gap on 1999 and Prior Model 260
Series Tractors
1. Turn the ignition and PTO switches to the “OFF”
position.
2. Locate the three access windows where the clutch
air gap must be checked (Figure 232).

4. To increase the size of the air gap, loosen the
three locknuts and springs.
5. To decrease the size of the air gap, tighten the
three locknuts and springs (Figure 233).
