By reducing your motors hydraulic back pressure, theamount of available energy to the hydraulic motor increases and that energy can be used for work.Here are some of the most common sources of high hydraulic motor back pressure. 1.Tractor Return Valve Block A free dump return port is the best way to minimizereturn back pressure.This Free dump free dump return ports help toreduce the back pressure, but can vary for tractor models.A realistic back pressure goal is 50 Җ 150 PSI. return, bypassesthe tractor valve block spool and greatly reduces hydraulic back pressure. 2.Quick Coupler Size...

The Raise position is not recommended for OnӔbecause the valve must travel through the Neutralposition to get to Float.System Types: Hydraulic Plumbing: Do Not Remove Check Valve. There are three types of hydraulic systems used on tractors.One utilizes a constant displacement pump and iscalled an Open Center System because of the spool valve employed.The other two use a variable displacement pump and are known as Closed Center (Pressure Compensated) Systems or Closed Center Load Sensing Systems based on the type of spool valve and system operation.Open Center systems, while having constant...
