pto switch bad
The manual pto is the switch used to engage the mower deck.
PTO is short for Power takeoff. It is to control a shaft comming out of a vehicle to power things like a snow blower attached to the front, or to control things on the back of a tractor... I never heard of a PTO on a lawn mower... It must be a pretty big lawn Mower. PTO on a riding mower will be an electric engaged clutch used to power a belt drive or other attachments. Oh yes, your right.. perhaps it may be the pull handle to engage it also.
Typically this is caused by a bad seat safety switch.
There's a yellow switch in the upper right hand portion of the dash. It's the PTO drive. Engage your clutch, pull up on the switch and move it forward, and that should start the blades spinning. If it fails to engage, it could be a bad switch or a bad battery.
That could be alot of things. Check under the deck and make sure the PTO is plugged in., it could be one of those wires are bad., check all your safety switches and make sure they are plugged in good and finally it could be your switch.
Check the belt and if it isn't that, it could be the PTO. That's under the engine with two wires coming out of it. It will be in route with your blade belt
throtle setting not high enough, bad spark plug, Something else to check Newer mowers come with a safety interlock system that prevents mower engagement when no operator is on the seat or when the parking brake is engaged. Check your seat switch by junping across the terminals, if the blades start then the seat switch is bad.
This is most likely a blade clutch problem. Many times they short and have to be replaced.
The electric PTO Clutch is Electromagnetic. There is a stator which creates a magnetic field when voltage is applied and this causes the free spun pulley to lock into place with the crankshaft of the engine. When voltage is release, spring pressure forces the pulley away from the stator. This is over simplified but that is about it.
Your mower has an electric PTO clutch that is worn out. It clutch stops working when it gets hot. Replace the PTO clutch and you should be fine. Expect to pay about $150 for the part.
Yes pull pto up when pressing reverse pedal pto remains engaged. release when moving forward.
