When and how to replace the grader blade?

The box grader is a kind of earth moving machine which uses scraper to level the ground. The grader scraper is installed between the front and rear axles of the machine to lift, tilt, rotate and extend. It is suitable for the construction of subgrade and pavement, the construction of slope, the excavation of side ditch, the mixing of pavement mixture, the removal of snow, the pushing of granular materials and the maintenance of soil road and gravel road.

 

The tractor grader blade is the most important part of the grader operation device, which is located between the front and rear axles of the machine, used to complete stripping, transferring soil and leveling, paving, mixing and other work. Correct maintenance is very important to maintain the best performance of the grader, and the most important thing is to ensure that the grader has a good cutting edge. The time required for skid steer grader blade edge wear depends on the abrasiveness of the material and the angle of contact between the edge and the material.

 

 

Time to change blade

Generally speaking, when the grader exposes about 3.5cm of usable space on the 3 point hitch grader blade, the operation efficiency is very high. If the edge is worn too much, the level best box grader will not function as it should. There is also a risk of wear right into the plow board, which may then have to be replaced. Depending on the type of material the grader cuts, the manufacturer recommends a visual inspection of the cut edge every 25 to 50 hours.

 

 

How to replace the blade

When replacing the compact tractor grader blade, it is better to wear gloves, safety helmet and fitting clothes, which are not easy to be stuck by the equipment. Block the tandem wheels at the front and rear of the grader. Make sure the parking brake is set and start the grader. Lower the plow until it just touches the ground without applying downward pressure, then turn off the grader. Get off the horse safely. Remove the bolt from one section of the cutting edge at a time. Usually up to 12 bolts hold the heavy duty grader blade in place. You should check the bolts and replace any worn bolts. Remove the road grader blade, stand beside it and make it fall off the plow board. Use a wire brush to clean the surface that will hold the cutting edge, and then hold the new cutting edge part in place. Insert in bold, secure with nuts and tighten bolts. Remove the block from the wheel of the grader, start the grader, and lower the plow until all its weight is on the ground. Move all controls to the neutral position and turn off the land pride grader. To replace the separate cutting edges on both sides of the plow, you can perform another step. First, lift the blade evenly about 20 cm from the ground, and put a cushion block at each end of the plow board. Lift one end of the plow board until the other end falls to the ground. Replace a cutting section. Then reverse the program and change the other part. Once you have successfully installed a new cutting edge, remember to store the worn cutting edge for safe disposal.
