Tractor rolls back.. Is it possessed?

[woodlandfarms]

OK.. Since I changed out the left rear hydraulic motor hose, (and maybe before, although I never noticed). If I put the tractor on flat ground. Run up the engine, take off the brake, I will slowly roll back. It did it today, I lilfted the front end with the bucket, and with the engine running the lifted wheels rolled slowly backward.

Hmmmm... there is some poor chap buried on our property... Maybe this is it...

On my 1445, there is an adjustment to center the pedal and the valve, so that no movement occurs. You should get that fixed as soon as possible. It might roll back over your foot, or something else. Some people shut the engine off when out of the seat. I don't, I try and be extra careful. For those hook and unhook, jobs it is just not practical.

Every hydrostatic machine that I have ever operated has an adjustment to the forward/reverse mechanism so that when you take your feet off the direction controls, all wheels should stop turning. If you do not have a manual for your machine, you should call Power Trac and ask them for the procedure to correct this. I believe you will have to put the machine up on jack stands so the wheels are off the ground and make the adjustments. It is a regular part of maintaining any hydrostatic drive machine.

PLEASE DO IT !!!

I always* shut the tractor (PT425) off before entering or leaving. The reason is that when I was considering buying a PT, which I have never seen before, an owner about 75 miles from me in northern California invited me to come up and test drive his. I was impressed and so I bought. I was also impressed by his story about how his had rolled over his leg and broke it. I swore the that I would never take that chance. I never did until two days ago.

I was having a problem with my tractor, an electical problem I believe, and the only way I could start it was by jump starting it from my pickup. The day before my wife had bought a dozen rose bushes and wanted me to dig holes for her. I hooked the 425 to the PU and it started right up. The problem was that if I turned it off before mounting up it would die and be unstartable so, for just this once, I unhooked the jumper and stepped aboard... almost. To this day I do not know what happened but the PT lurched forward knocking me down. In the process it rolled over my left angle, climbed aboard my right leg and ran along it and stopped atop my right ankle. It was enough the make a preacher curse and an atheist pray.

Fortunately my wife was about thirty feet and rushed to my aid. As I lay there pinnned by the tractor my greatest concern was that she would turn off the switch leaving me trapped. After considerable loud shouting convincing her NOT to kill the engine I explained to her how to press the peddle gently until it rolled off my leg.

Someone up there must like me. No fractures. Two very bad sprains with ankles swollen like oranges. For two days It has been a regimen of rest, ice packs, compresses, feet elevated, etc. Fortunately my wife used to be a nurse.

I KNEW what I was doing was dangerous so I was being extra CAREFUL. I never saw what hit me. If my wife had not been nearby I would have lain in the 100 degrre sun until someone eventually came looking for me. It may be inconvevient getting of the tractore to connect hgoses, etc. It is not that inconvenient taking time to turn a switch off/on.

I did not know you could hook and unhook hoses on the PT with the engine running? I assumed the engine had to be off....

The engine doesn't need to be turned off but the PTO switch does.

The engine doesn't need to be turned off but the PTO switch does.

Another dangerous think is to connect or disconnect these hoses with the engine running. If the shutoff valve leaks, you could get hot oil injected into your skin. I don't know all of the issues, but the PT trainer told my to shut the engine down whenever you mess with hydraulic connections.

If you had a new PT, and the PTO switch was off, you might be able to hook up the quick connects with the engine running.. The flat face quick connects are designed to hook up under pressure. They are more expensive.

Bagtic,

Sorry about your trouble. Your foot must have touched the pedal. I have done something similar. Getting in the seat of the PT, my foot touched the pedal and it jumped a bit. I am not saying that is safe. Same with the seat belts, some wear them all the time, and some don't. I also keep my cell phone with me all the time.

I always turn mine off for that very reason. I understand why you did what you did, but it is always better to be safe. I keep my walkie talkie in my PT. In that situation don't think I could have reached it. We forget sometimes because these machines are small how powerful they really are. Glad you are ok it might have been worse.
