2025 Bush Hog® Flex-Wing Rotary Cutters 3815
HEAVY-DUTY FLEX-WINGThe 3815 Flex-Wing is built for the toughest cutting conditions. It is recognized by right-of-way contractors and large land owners as the Flex-Wing that can perform over the rugged terrain, day in and day out. The ease of maintenance features, durability, reliability and overall performance combine to make the 3815 an excellent value for your investment.
Features may include:
PERFORMANCE- Wing and center skids are 3/8-inch thick for extended wear and outside edges are turned up at 45 degrees to stop heavy ground contact that might damage the sidebands.
 
- Center section axle spindles are centered on the axle arm for equalized loading of vertical forces.
 
- Grease fittings and spring steel bushings at axle pivot points for longer life.
 
- Free wing float without movement of the hydraulic cylinder rod is 22° down and 45° up.
 
- Improved suspension that absorbs more shock loads at the tires.
 
- Seven gauge deck plates for stronger decks that are less susceptible to damage.
 
- Heavy, durable axle arms withstand the shock and bending loads generated when used on the roughest terrain.
 
- Industry first — 3-inches O.D. output shaft in cutting gearboxes.
 
- Reinforced blade pans for maximum durability in heavy cutting conditions.
 
- Wing drivelines are ASAE Cat.5 for use in heavy cutting conditions.
 
- 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
 
- 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, reducing service times.
