We know all too well the frustration of putting your heart and soul into a crop only to have the wildlife consume it before you can get it harvested let alone to market.

Place wheels on axle. If wheels do not fill axle completely to the turned shoulder, fill up the space with axle rings. See that axle and end bearings are well greased; then place brackets on axle and secure with axle washers and cotters, using that notch in the washer which allows the least possible end-play of wheels on axle. Bend ends of cotters around washers so they will not catch on the inside of dust caps.
