About this file
This document is a technical specification for a 2 disc trail type fireline plow. The plow has an overall length of 10 feet 6 inches, with a working length of 5 feet 4 inches from center pull pin to center wheels, and a width of 69 inches overall wing to wing. The frame consists of 4" x 8" x ½" tubing measuring 10 feet long, with a 42-inch crossmember featuring 4½" O.D. axle sockets. The plow is equipped with two C-1141 alloy steel axles (3½" diameter, 50" long) with welded wheel hub spindles at 90-degree angles, and features a P-74 swivel-type drawbar coupling with 3-position adjustability.
The plow incorporates dual 28-inch diameter discs with 3/8-inch thickness and 5½-inch concavity, constructed from Labelle high-test heat-treated steel, paired with 30-inch diameter coulter blades of matching thickness and heat-treated steel construction. An H500400 middlebuster measuring 20 inches wide is fabricated from manganese moly heat-treated, heat-resisting steel. The assembly includes 5-hole Budd-type heavy-duty wheels (16" diameter x 11" wide, 2-piece bolt-together rims), airplane tube tires (40 x 14, 20-26 ply), and ductile iron disc and coulter boxes equipped with taper roller bearings and grease seals. Mouldboard-type wings are rolled from ½-inch A-36 steel plate to prevent turf rollback. The plow features a double-action hydraulic cylinder with 4-inch bore, 2-inch ram diameter, and 16-inch stroke, with approximate total weight of 3,200 pounds.
