PTO can be engaged or disengaged without operating clutch. Push down and forward on PTO switch (A or B) to engage PTO clutch. Pull back PTO switch (A or B) to disengage clutch.
How tight should a PTO slip clutch be?
To adjust Slip Clutch, tighten Bolts (1) until the Nut makes contact with Compression Spring (10). DO NOT tighten any one bolt completely, tighten in rotation to ensure equal pressure all the way around on Friction Disks and Drive Plates. Tighten each Nut one-half turn in rotation.
What does a PTO clutch do?
Power take-off (PTO) clutches provide a mechanical disconnect between the power created by gas and diesel engines or electric motors to another piece of equipment. The PTO clutches enable the transmission of that energy to auxiliary equipment that does not generate its own power.
What would cause a PTO to not engage?
Two common reasons that a PTO won’t engage are installation issues and owner misuse. Addressing these possibilities first might be the only thing needed. Additional problems could arise if the switch is showing no continuity. Check for continuity using a multimeter.
Why does the PTO not engage?
If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it. The PTO switch provides power to the PTO clutch. If the PTO switch is defective, replace it.
What causes PTO clutch failure?
PTO clutches generally overheat because of improper lubrication/greasing (both too much and too little can cause problems), excessive sideload, or a new installation.
How does a PTO engage?
The PTO is engaged and disengaged using the main transmission clutch and a remote control mechanism which operates on the PTO itself. Typically, an air valve is used to engage the PTO, but a mechanical linkage, electric or hydraulic mechanism are also options.
