The hydraulic hose on top is just a return from the hydraulic valve for the dozer. It seems to have 3 positions and definitely seems to have something to do with the transmission, it feels like it's shifting something. It has no effect on any speed or direction or the rear pto. It doesn't have a front pto that I can tell.Never seen that application - but this is a SWAG - seems that you have aux hydraulics for something else you are using, that lever seems to control the flow or direction of the fluid. Are those for rear hydraulics?
Can you take a picture by pulling away a bit ? Show more of the tractor, it may help determine what specifically that does.
I thought at first it may be a creeper gear.The hydraulic hose on top is just a return from the hydraulic valve for the dozer.

That is a creeper gear set up. Normally installed when using a trencher. These were installed by the dealer on the early B7100. The original transmission cover was removed and this unit was installed.
owners manual has been e-mailed.Yes I would really appreciate it.
