I am looking for a hydraulic motor that can run a screw for rotation of a 10' grader blade on a old A/C Model D Road Patrol Grader so I no longer have to do it manually?

A: Please contact our Product Support department with more details regarding your hydraulic system and application.

Can this motor be used in a chain or belt drive application? will it with stand the side load?

A: It can tolerate reasonable side load in relation to the speed and shaft size. At 1000 rpm with the load centered on the keyway, it can be expected to handle at least 120 lbs of radial load. At lower speeds the force tolerated does increase proportionally.

looking for a motor that can be used to drive a brush cutter

A: First you will need to see how much horsepower at what rpm it takes to properly drive your cutter. Then you need to see what hydraulic flow and pressure you have available to drive a motor. Finally you need to know at what rpm you need the motor to turn. With all those answers you can size a motor for speed, then calculate the horsepower developed with the torque at the operating pressure. If the motor will be able to turn the correct rpm with the input flow, and provide at least the minimum horsepower for the cutter at the operating pressure of the motor, that item would be an acceptable option.
