Blades wont disengage completely

Washers have transmissions. Maybe this one has issues.

Replacement of the PTO should solve the problem as these do corrode internally and stick.

A faulty switch if the blades are spinning at full cutting speed
Not cutting the current to the engaged blade clutch so the blades are stil on even when the switch is in the off position.
The blade brakes not gripping the pulleys fully to stop blades so anything brushing against the blade will start them spinning
Or the clutch medium is damaged and is not releasing the blades fully so they spin but slowly when you switch the switch they just slow down get the deck alignment switch for clutch and the wireing to the blades system checked and the braking system for the blades pulleys checked as soon as possible the machine is dangerous
With the blade continuously rotating you risk injury from the blades catching.g you or someone else who's not aware the blades don't stop.etcetera.

Under seat of tractor theres a plate that says model # it looks like 917. 000000 i need that # please and i can help you with the problem it sounds like the belt isnt disengaging which will cause blades to continue to go.

Blade speed equals engine speed. Check your carburetor and fuel pipe
Make sure you sharpen the blade with - this is more important for a good cut.

The brake mechanism works when tension is released from the idler / cable. The brake is spring loaded to contact the spindle this stops the blades from spinning. I have attached a drawing showing the brake arm and where it can be found on the deck.

Hi Tim, Check the filter to see if it blocked .. also, take note to see if the machine is gathering a full spin speed, if not, you may need new brushes in your motor

Take a paperclip and clean out the small hole on your gas cap. And yes I am being serious.
