Canyou describe how to hook up the hoses to do this?
Sure. It has been described. Let me try.
Look at your tractor picture. Can you identify P? That's the pump line. It's the QC closest to you in the picture.
If you take that middle QC off, the one with the green band, I think you will drain your sump. So let's call that T for Tank.
The front most of the three in the picture must the the lift...a "load beyond" the loader valve, so that would be a great place to use "power beyond."
If you just want to start the tractor, connect pump to either of the remaining connections, but I'd suggest the front QC so you can try the lift.
Don't be fooled by a lift that is up, but won't come down under gravity. I have to stand on my upper arms to get them to go down, and yours could be doing a bit of that. My lower lift links are removed for the digger, so it could just be mine that needs additional weight to go down.
I could be wrong, I suppose, but there is wrong and then there is CRACK wrong. I believe if you hook the pump to either place, you can start the tractor without ruining a pump, but if that were my ultimate goal, not testing, I'd hook pump to that closest port, the one I am calling T.
