Mowing GX345

[n3plf]

This is the first time I am posting anything, I hope I am doing it right. I have a GX345, I will be mowing and all of a sudden the PTO stops. The tractor continues to run fine. If I sit there and keep pulling the PTO switch on and off sometimes it starts again. Or if I leave the switch on and just drive around it will start up again. When it starts it runs fine for 10 min. to a hour. I assume it is a connection or a loose wire. I have cleaned all connections and when it stops running I have played with the wires and nothing happens. There doesn't seem to be a pattern. I have been sitting on my macadam drive not moving and it just starts or stops. I hate to just start replacing parts. I hate problems like this because I know that if I take it to my JD dealer it is going to run fine and he will look at me like I'm nuts. Any suggestions as to how to pin point the problem would be appreaciated.

If your guess is a connection or loose wire, there is no need to throw parts at it. Get out a multimeter and measure the PTO switch resistance. Is the switch bad?

Measure the power at the PTO clutch - is it getting power? Is it sufficient voltage?

GX tractors use an Ogura PTO clutch. As the brake that stops the mower wears, the air gap increases inside the clutch. At some point the gap becomes large enough that the electomagnet that operates the clutch cannot hold the clutch engaged. As your experiencing, it happens sporadically. Your clutch air gap is adjustable via 3 nuts toward the bottom of the housing.

Easy fix.
