Adjust the skid shoes to allow the required clear-

ance under the blade. On level, paved surfaces,

adjust the skid shoes to allow 3/16 to 1/4 in. (5 to 6 mm) clearance between the cutting edge and the

surface. On uneven or gravel surfaces, allow 1/2

to 5/8 in. (13 to 16 mm) clearance, depending on the size of the gravel. Refer to Skid Shoe Height Ad- justment illustration.
