Removing the blade
Most riders have removable blades. To get the blades, remove the cover before the service. DO NOT tip the mower on its side. This can cause serious damage to the device.

Sharpen blades
Sharpen the blade riding lawn tractor with a tool such as a file by hand, which are designed for use on hard metals. It is not necessary that the blade is sharp as a knife. One advantage is about 45 degrees will be sufficient. Most will wear at the tip of the blade. Concentrate on this area. If the blade is worn or cut a lot to repair, replaceBlade.

Balancing blades
Before installing a new blade or sharp, it is important that the blade is balanced. If a blade is not balanced properly, it will rattle and vibrate. This will damage the other components of the mower. Blade balancing tools can be purchased at a local shop for a reasonable price. Clean all dirt and debris from the blade.

The horizontal test method is the second thing is that when one side of the blade begins to drop toward the table. The side you fall on the table or along the side heavier, and requires further refinement, or to compensate for material removedBlade. After sharpening the blade balance test again and repeat until the blade is balanced. Follow the procedure described above for the remaining blades.
The installation of blades
Once the blade has been sharpened and balanced, you install it in the correct orientation. If you are an OEM blade that has the "bottom" to the printed word on the blade side that should face the floor. If the "low" does not exist, make sure that the blade increases with the tips toward the tip to install the bridge. TheBolt or nut must be tightened to 70 ft to 100 pounds. Couple.
