Skid Steer & Tractor Requirements

The AP-SG25 Series Skid Steer Graders are designed 
for skid steers and tractors with a front loader that is 
equipped with a skid steer mounting plate. Tractor 
horsepower should be within the range noted below. 
Tractors outside the horsepower range must not be used.

Tractor WeightSee Danger alert below
Required Horsepower Range40 - 95 horsepower

DANGER

!

To avoid serious injury or death:  

Use a skid steer or tractor of adequate size. A light weight 

machine can tip over causing serious injury or death when 
loader arms are raised due to high center of gravity.

Some light weight skid steers and tractors will require rear 

ballast for heavy loads to maintain control. Be sure to 
consult your machine’s Operator’s Manual to determine 
whether or not to add ballast.

Torque Requirements For Bolts

Refer to 

“Torque Values Chart”

 on page 20 to 

determine correct torque values of fasteners.
