Features

Performance Features
  • Free Wing Float, without movement of each hydraulic cylinder rod, is 22° down and 45° up.
  • Each cutting gearbox has the industry’s first massive 3-inches output shaft with more splines that are deeper for maximum transmission of torque to the blade pan.
  • The 2820 is available with Round Blade Carriers or Straight Shredder Blade Bars. The optional Shredder Kit will increase the shredding performance even more that the straight shredder bars.
  • An optional Material Distribution Baffle Kit spreads cut material to eliminate windrows.
  • Each wing has a single deck without exposed structure underneath.
  • The 2820 is available with optional deck rings that reduce the possibility of blade to deck contact.
Construction Features
  • Blade Pans are reinforced for maximum durability.
  • Spring Axle Cushions are located near each wheel for maximum shock absorption.
  • Wing Skids are formed upward at 45° to prevent “dig in” on turns that might damage the sideband.
  • Grease Fittings and Spring Steel Bushings for minimum wear are at each axle pivot point.
  • The center section has a doubled deck with no exposed structure for a smooth flow of cut material.

Safety Features

  • Highway travel lights are standard for safer travel on roadways.
Product Features
  • The Patent Pending oil sight gauge takes the guess work out of checking the oil. In less than 10 seconds, all three cutting box oil levels can be checked and rechecked as often as you walk around the machine. Never climb onto the cutter again to check the gearbox oil levels.

  • Bush Hog’s E-Z lube drivelines are quick and easy to service. All grease fittings on the pto CV driveline and wing drivelines align for quick location of grease points. Since all grease fittings on all drivelines are in an up position on every 5th revolution, service times are reduced.
