The Model 1375 Offset Disc - The same 8” x 4” x 3/8” steel tube frame as the 1275 but with ballast for extra weight, the 1375 is ready for serious work. Heavy 28” x 3/8” (9mm) notched blades are standard. Massive fabricated tubular hangers are affixed to Ezee-On’s T2-215 bearings. 12” spacing is standard to ensure optimal trash clearance and an aggressive cut. All this weight and strength combines for a 361 lbs. average weight per blade. Widths range from 10’ to 15’.
