Hydraulic System
The Hydraulic Cylinders are designed to be used in conjunction with your tractor's Hydraulic System. The
Cylinders and Hose are designed for maximum system pressure of 2500 PSI.
Keep Cylinders and Hoses free from internal contamination. Never leave a disconnected
Hose end open. Use a Sealant when attaching Hydraulic Hose to Cylinder. Do not over
tighten fittings as this will break out the Cylinder Port Housings. Do not operate with
hydraulic oil leaking. Oil is expensive and its presence could cause slips and falls and other
hazards. DO NOT CHECK FOR LEAKS WITH YOUR HAND. USE CARDBOARD
INSTEAD. High-pressure oil can penetrate the skin and cause tissue damage or even
GANGRENE. If oil does penetrate the skin, have it REMOVED IMMEDIATELY by a
surgeon skilled in this procedure.
Hydraulic Control Valve (Accessory Equipment)
A three-spool, four way Hydraulic Control Valve, Open Center or Closed Center, is available as Accessory
Equipment. This allows you to operate four Hydraulic Cylinders from two remote outlets. Connect the three-
spool Valve to one outlet to operate three Cylinders. Use the other remote outlet to operate the fourth Cylinder.
If Closed Center Valve is used, Do Not Use the Adjustable Relief Assembly. Use the No-
Relief Assembly.
