Measure the width of the wheelbase from the outside of the left wheel to the outside of the right wheel. Use a tape measure for this. Knowing the wheel base allows you to make a wheel block that extends across both wheels. This increases safety and reduces the likelihood that the weight of the vehicle will push the wheel block.
Cut a piece of 4-by-4 lumber to match the length of the wheelbase. Use a circular saw, miter saw or band saw to make the cut. Since the Muck Truck is designed for use in sloppy conditions, use treated lumber for the wheel block.
Cut a 12-inch long by 1-inch wide strip of nylon fabric with scissors. Double the fabric over to create a 6-inch long strap.
Cut a slot into the top of the strap and then secure the strap to one end of the wheel block with a ½-inch diameter lag bolt. The strap lets you pull the wheel block out without having to get down on the ground. This will help to keep you cleaner.
