The Beatty grader is a modified ditcher originally manufactured by General Machine in Spokane, WA (Figure 19). Although this manufacturer is no longer in business, Idaho Falls Foundry and Machine, in Idaho Falls, ID, has molds to manufacture new graders as well as replacement parts. The Beatty grader was designed to function both as a finishing tool following a hillside plow, and as a trail tread maintenance tool. This implement is heavy. The grader, complete with single tree and handles, weighs 250 lb (113 kg). The grader is designed to operate on an off center pull to create a landside or hillside draft (Figure 20). Draft is adjustable from approximately 4 in (100 mm) off center to approximately 12 in (300 mm) off center (Figure 21). The wing can be adjusted to grade a tread of 11 to 26 in (280 to 660 mm) wide (Figure 22). All parts are mounted with either pins or bolts to allow easy dismantling for packing. In its original design, several points were available as accessories to allow easier operation in heavy rubble and beargrass.
