Pto Switch; Switches - Toro Groundsmaster 4000-D Service Manual

PTO Switch

The PTO switch is used to engage or disengage the cut-
ting decks. The PTO switch is attached to the control
console next to the operator seat (Fig. 13).
Testing
The switch terminals are marked as shown in Figure 14.
The circuitry of the PTO switch is shown in the chart be-
low. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
position. Verify continuity between switch terminals.
NOTE: The PTO ENGAGE position requires lifting and
pushing the lever toward the switch keyway. The PTO
OFF position occurs when the lever is pushed opposite
the keyway.

may be tested to determine whether continuity exists
between the various terminals for each position. Verify
