Locked up rear end

That's what I'm hoping

I will change my bend to flex if that makes a diference[/quote]


Please share what you saw, heard, felt, or tasted that told you that your tractor flexed.

. I was chewing spruce gum! but the tractor stopped moving forward and began to flex in the middle under my seat. A plastic shroud under my seat that usually is tight to floor mat is now up off mat by inch. Whole tractor is under loadfrom what appears to be something bound up. There were no sounds out of the ordinary like: poping, squealing, or breaking noise the energy just seemed to be absorbed in the tractor instead of rotating the wheels. Shut off immediately by key as soon as I felt the flex. It's been in the flex or stress position ever since. Unfortunately my back went out the next day and is just feeling better today. So haven't looked at it since. My knowledge of hydrostatic tranies is not great but I am a macanical person. I do most of my own work.

Hydrostatic transmissions have been around since 1969 so I would think that the problem might well have been addressed by someone on this form. That is why I am here. Tractors of the compact designe are pretty basic tractors like the old ones. An energy source and places to put that energy. The technology has not changed in that manner. So I think it is appropriate to ask this community for their help. I would help and probably have the people in this community in my own neighborhood.

With this information I suspect that the plastic shroud moved and came out of place relative to an adjacent part, and that it will, upon removal, come free of the interference and go back into place, and it will also release the interference with a control rod that is keeping your Branson stuck in gear. After a few more hours on the heating pad get that shroud off then back in place and get it back to work!

The shroud is not holding the tractor up the flex in the rear end is what is holding the plastic shroud up the tractor is under load therfore the middle of tractor, at seat area is the flex point. What I have to do is figure out how to unload the backbend without causing damage or more damage

spruce gum eh. that's a new one to me.

my instinct would be to jack the rears off the ground. hopefully that's all it will take to shift it back into neutral.

So you have removed the plastic shroud?

 

[BarnyardEngineering]

Tractors, even small ones, should not flex or bend perceptibly under ANY circumstances. Any flex would only be measurable with a dial indicator, in the thousandths, or tens of thousandths, of inches. Any more than that, and the tractor is broken.

As this is a hydro there is no clutch to disconnect the engine from the hydro pump. If the pump is seized or blocked from turning because the tractor is physically broken, the engine won't turn.

From your description this is not a simple "hit it on top with a sledge hammer to straighten the bend out" fix.

 

[J.Wondergem]

On my hydro lawn clippers, each hydro unit has a little lever on it that you push down to put the hydro out of gear so you can move it. BUT, I know nothing about your tractor, just an idea.

Yes I think that is the problem. So I have to find where the blockage is. Is that what your saying

If you did actually bend or distort part of the tractor I
am going to say it is the stamped steel section that
sets between the clutch housing and the transmission
case. I found a parts book but it does not seem to
cover the hydro model. Either way I am sure both
models have a similar assembly. In the attached see
part P21-01 on page 100. It is my opinion that you are
using the tractor for a task that requires a heavier
designed and built machine to complete. I am sure
many on here will agree a machine that is adequate for
a task does not need to ..take a run for it.. to do the
job.

i just came back from a trip to the machine shed. i told my WD and its 6 inch channel iron frame rails that i loved them

I did not bend the tractor I stopped it before anything broke I think. Whit I am referring to as bent is the parts tat ate connected to.the housings, seat ,fenders. When tractor is under stress these can flex. What I have to do is take the load off the rear find out what part in the hydrolics is holding the pressure

 

[Samske]

Yes I probably should have a heavier tractor, with that said I will need a heavier one in two years following. I have used this tractor for 5 years and have done everything I needed it to do. Do I push it from time to time yes I do. It's not about what I do with my tractor it's about where I am with my problem do you know how to unload the built up hydrolic pressure that causing my tractor to lock up

 

[Samske]

You seam to understand the nature of my problem. At what part of the hydrolics should I start my search

 

[Samske]

just seen this reply I will try this thanks

 

[Samske]

no I'm saying it did this once I shut off when I felt strain and it's been in the stress position ever since. Won't start because I would think tractor sensors think it's in gear

 

[Samske]

no it's soft payable plastic

(quoted from post at 11:41:42 07/16/23) Hi thanks for alowing me to become a member. I have a Branson 2800 compact tractor and last week I was pulling a log out of the woods, it snaged up I gave it a little running tug and the hole rear of my tractor locked up almost bending the tractor in half shut off right away. It is a hydrostatic transmition. Now it will not start or move.everything is locked up

Why do I suspect the entire episode should have been videoed as a you tube how not to .
