Kubota M62 Drive Disengages By Itself

[NitroSteel1]

I’m having this exact same issue with my Kubota L47 when just using the front end loader (I’ve never used the PTO). Did you ever figure out what was causing this? I really appreciate the help.

Yes. The problem is the safety switch in the seat that shuts off the tractor if it does not detect the presence of the tractor operator. Unless I place all of my svelt 165 pounds of weight in the center of the bottom portion of the seat, the safety switch triggers as soon as I move the go pedal with my foot, which shuts down the engine. To reset the switch, I have to lift all of my weight off the seat momentarily while not touching the go pedal. The problem is especially noticeable when working on steep inclines, where I'm twisted around to the back of the tractor, and my weight tends to shift onto the back of the seat, causing the bottom of the seat to unweight somewhat. I suspect that the problem could be "fixed" by shorting the two leads going to the safety switch, but this would defeat the purpose of the switch, something that I'm reluctant to do.

The plastic underneath the seat supporting the seat safety switch starting cracking causing the M59 tractor to loose power. Usually on steep or bouncy terrain. Became a safety hazard. Didn’t like it stopping the tractor the few times I needed to stand for better sight. Replaced with simple waterproof switch and could use as an anti-theft devise.

I have this same issue on occasion when doing some work operations and moving around in the seat. Rather than bypass the safety switch, I use a mechanical twist timer to bypass the switch. When the problem occurs, I give the timer a twist which fixes the issue temporarily, but returns to normal automatically when the timer times out.

Weight on the seat interlocks cause nothing but grief and never saved anyone anywhere ever. Bullcrap that probably originated with lawyers. I guarantee it never originated with a farmer or tractor operator. Our world is full of this protection of ourselves disease.

Ever since I tossed that dreadful OEM non-stick seat and installed a Grammar air ride seat, the seat safety switch problem has gone away. The safety switch in my Grammar is very forgiving - probably because the seat is made to hold a human body in place instead of shedding rain/snow like a 4/12 pitch steel roof.
