The Tractor Power Steering Kit has been designed for older-yet-still-utilized tractors that didn't come with power steering. The manufacturer now offers kits for the following makes and models: Ford 8N, NAA, 600-, 800-, and 1000-series; IH 300-, 330-, and 350-Utility; Oliver Super 55 and 550; and John Deere 650-, 750-, 850-, 950-, and 1050-Utility. A complete you-install-it unit, which does not require hole-drilling or welding, includes power steering cylinder, adjustable priority flow valve with relief, torque generator, steering column, and steering wheel.
