Why mower blades will not engage when buttom is pulled

If you are sitting on the tractor seat and the engine stalls when engaging the PTO mover blades I would check the switch under the seat.

This seat has a saftey switch to assure that the operator is in a safe location before engaging the the blades. Also if the blades are engaged and the operator leaves the seat the blades will stop. If a young rider with insufficient weight the blades will not engage.



Hope this helps?

you do need to be sitting on seat for this to run , if you are but it still dies then you'll have to invesigate switch out they do go bad sometimes

Turn the key switch to the on position. Pull the blade engagement switch on.Look under the engine and find the electric clutch. Disconnect the wire connection there and while using an ohm meter, check and see if there is 12 volts on one of the wires. If so, then the clutch may be your problem. If not, then you need to trace back the wire from the clutch connection and find out why there is no voltage

Bad electric pto and also there is a fuse up by the dash underhood if thats blown it will not start from key.

check for power and ground going to the clutch

check the safety switches

I see this problem not as an electrical but a seize problem. Since I can't be there to inspect I am relying on your discription of the problem. I would go first to the place of the problem. If this solenoid goes up to disengage and down to engage ,or the opposite, this is most likely your problem area. It may be seized in the disengaged position therefore not allowing the blades to get spinning. Disconnect the belt and try to turn unit by hand, if tight or completely stuck use penetrating oil on pulley shaft.If shaft loosens up and blades engage this was the problem. Is there a grease fitting anywhere in the area?I hope this at least gets you started in the right direction. GOOD LUCK.

Unfortunately, the circuit is a little complicated - it involves the "PTO switch" (the switch you pull on to engage the mower), a "reverse switch" that senses if you've put the mower in reverse, and a relay operated by the reverse switch. The reverse switch is there to disengage the blades if you try to reverse while mowing. A failure in any of those items, or the connectors and wiring between them, will prevent the blades from engaging. Unless you want to "shotgun it" and replace parts one-by-one on a guess (which many repairmen to do save time, but at your expense) you need to use an ohmmeter or test light to trace and isolate where the failure is.

maybe the safty switch under seat might be starting to go out if that switch doesn't work the blades wont come on at all for safety

Is this on the grass, grass may be too long stopping blades from moving.
