Blades RZT54 PTO Disengages when hitting small bumps

[wolverick]

This has really been an issue since buying this mower two seasons ago. But it seems to be worse now. Every little bump I hit, the PTO disengages. So I turn it off, and back on at least 10 times every time I mow my 1 acre lawn. Any advice to help this?

start off by checking wiring at backside of switch down to PTO clutch, make sure wires are not pinched, bare, chafing, etc., make sure all wiring is tight & secure. let us know what you find.

Check/clean/tighten your battery terminals and make sure it's mounted securely too.

An overly sensitive seat switch will do the same thing.

Won't the engine just cut out if it's the seat switch? That's what my mowers do...just a momentary studder and the PTO stays engaged and I just keep going.

Depends upon the wiring.
Some shut down the engine some shut down the PTO
Some shut down the PTO then shut down the engine using the delay module.

In any case, a momentary shut down of the engine usually shuts down the PTO if it is controlled by a relay
A momentary shut down of the engine will not shut down the PTO if it is just the PTO switch.

Ok, thanks.

Thanks for all the advice. It does seem something with the seat being sensitive now that you mention it. Sometimes the blade won't even engage if my son (who is only 12 and is very light) is driving it and it cuts off on him much more frequently.

I'll look over all the wiring this weekend and post back anything I find.

I have also found sliding the seat forward also makes the issue worse. I have tested mowers with this issue and have had it happen with me with the seat slide forward, and I am over 200 pounds.

I am with the guys saying seat switch. I am sure it is a safety switch
