Initial Setup.  Two things are very important to the proper setup of the M-series Harley Power Box Rakes. Make sure that the U-bolt nuts holding the Tooth Roller Arm are tight and the Tire Pressure is correct in both tires. Harley Rakes feature independently adjustable gauge wheels so that you can level the tools roller for precision flat grading or allow it to be lower on one end for cutting drainage grades. They also allow you to choose exactly how deep you want to work in the soil. For instance on M6 skid steer rakes, a 2" depth can be set by lowering each tire until there are approximately three fingers spacing under the tires pivot Shaft's top washer and the tire support arm.

Keeping the Tooth Roller level when angled. The most important thing to remember when using a Harley Rake is to keep the rake level from front to back. That means, when the rake is working at the chosen depth, the chain case will be straight up and down, no tipped back or forward. By keeping the rake level, you will ensure that the rake will be setting a level grade even when it's angled. If the rake were tilting forward or backwards, you would notice that one end of the rake would be lower then the other end when angled, instead of the tooth roller being parallel the ground. Picture a helicopter's rotor blade tilted near the ground on the left and up in the air on the right, instead of both the same heights off of the ground.
