I am building a mini dozer using a walk behind brush cutter chassis with Hydro Gear hydrostatic drives.
I need to know if I can utilize hydraulic pressure from the hydrostatic drives to power the lift and angle cylinders for the blade. It seems like the return to tank lines would have pressure that could be routed to the control valve for the blade ????

:welcometogttalk: Sounds like a fun project. I'm not a hydraulic guru, but I'm pretty sure there is NO pressure in the lines returning to the tank. Hopefully, someone more well informed than me will be along soon.

Without knowing what type drives you have, it's hard to say, but likely not. There is only a tiny amount of flow through the return lines unless the drive is moving forward or reverse, and then it's not what you want for hydraulics. Diverting flow at this point would stop/slow the hydro's movement function (& may blow a seal?). Hydro's must be "ported" for hydraulic lift purposes.
