I've been looking at newer sprayers and so many have hydraulic motors that run the sprayer pump and I'm wondering if a 7020 will handle that. From what I've seen the pump would require 11-12gpm @ 2000psi max and the boom control (raise, lower, fold)would require 3gpm @ 2200psi. For what I would be doing I would not need the max volume & pressure out of the sprayer pump so I should be able to reduce the hydraulic flow on the tractor to maybe half and I can run a low pressure return back to the tractor to help reduce back pressure restriction. Basically I would using both tractor remotes continuous while spraying, I don't want to overheat the hydraulic system and damage something. Anyone else running something similar or know if this will work ok?

Thanks,

Chad

Should do it. Dad runs a Hiniker air blower with his 7060.

Control the volum with the controles under the seat. Don't use a flow control on the motor. MACK
