Can you manually turn the pto hookup on the back of the tractor?

[Runner]

Three very unlikely things would have to happen at once for my rear PTO to start on it's own with the engine running and no operator on the seat while I am hooking up the rear PTO.

First, the PTO lever would have to be moved from the front position to either mid- or rear position (or, there would have to be some really strange mechanical failure to make this happen internally without moving the lever).

Second, the PTO switch on the dash would either have to be intentionally engaged or there would have to be some kind of short to cause it to engage.

Third, there would have to be a short in the operator seat sensor that would allow the PTO to start without someone in the seat. Yes, you can run the rear PTO without someone in the seat, but the parking brake has to be FULLY engaged. Whether intentional or not, my parking brake has two detents, first detent will hold the machine under most conditions (i.e., just parked on the driveway, etc.), the second detent which is FULLY applied, is what operates the seat safety bypass allowing the rear PTO to operate. I don't think it is actually designed to work this way, probably an adjustment issue, or quirk, but that is how it's always been since new.

I can set the parking brake so the tractor won't move, but it won't be enough to activate the seat sensor bypass, so the engine will die if I engage the PTO. Have to remember to push the brake pedal HARD, then set the park brake.

When I am hooking up the PTO, I always have the parking brake set on the "easy" position, so the PTO can't start.

Due to the extreme unlikelihood of all of these conditions happening at once, I have decided that it is OK to hook up my rear PTO with the engine running.

But I wouldn't recommend it for anyone else.

my tractor has a toggle switch to engage pto. no way i trust that. i shut tractor down when messing with pto.

One short circuit could make a very bad day. Good choice.

operator seat sensor that would allow the PTO to start without someone in the seat.

Many people bypass that safety switch. Otherwise, running something like a wood chipper requires a 2nd person in the seat full time.

just add a simple overrunning clutch. easy to turn by hand, plus helps protest tractor when turning pto off.

Did you have to cut down your PTO shafts after installing?

The 2520 allows for off-seat PTO operation (rear PTO only), just need to have drive in neutral and parking brake set. You can engage the PTO while sitting on the seat, then get off, or engage it while off the seat.

My dk45 does not have a seat switch. Never had one. Its a cab unit, so i guess they didnt think it needed one. When chipping wood, i simply open door and flip toggle switch ant chipper starts to turn.

Regardless, I've been around lathes, milling machines, and other shop tools capable of killing you for a long time, so you learn how to behave around those machines and what you wear/use around those. Longs sleeves are a no no and so are gloves. Exactly the stuff that can pull you and wrap around the shaft. At on point or another, you have to touch the chuck while spinning either to use some emery paper or just chamfer an edge with the file, etc.

Agree, a shop with LARGE machines have threats around every corner. I have seen some bad accidents in shops in my lifetime but managed to get to retirement with my life and all my fingers.

There is some way to get around that on many tractors if the brake is fully engaged. (I would have to read my manual again.) I disabled mine because I couldn't even turn on the seat to look at where I was tilling or mowing without the switch shutting the engine down.

To jyoutz, rScotty, grsthegreat, Jstpssng, myself and all the rest. Some folks may have a death wish, better life insurance than we do - or both.

I simply do not attach any implement with my tractor running. PERIOD.

Yes - I do move the 3-point arms and hydraulic top link with the tractor running - when attaching implements. But the simple logistics require that I be on the seat when I do this. My arms are not long enough to reach the controls while standing out back.

One thing i love about my cabbed tractor is they placed additional controls outside by 3 point so i can move this up and down while outside. I can also move tractor forward or reverse while standing outside cab. After implement is hooked up, i shut er down to hook up pto.
