All Flex-Wings undergo extensive testing in all growth conditions to ensure each meets our demanding performance requirements.

For long axle life, all pivot points have grease fittings and wear bushings.

A one-person operation, the tractor drawbar is easily backed into the Perma-Level hitch. Notice correct position of hitch.

The circular formed deck rings position outside of the blade carrier to reduce the possibility of a bent blade cutting the deck plate.

The Patented 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.

*Above acres per hour have already been reduced by 17% to allow for overlaps, turns, and rest breaks.

Each axle arm has a strategically placed spring cushion to absorb shock loads near the wheels.

The transport lock-up device is easily positioned to take the load off the hydraulic cylinder rod during transport.

The quick detach shields allow easy access to the driveline clutch and grease fittings.

The wing skids are in two pieces for more economical replacement and the 45 degrees of up- turn allows the skid to float over the ground instead of gouging in. This prevents possible damage to the sideband.

Highway lights are standard equipment. Lights provide flashing and turn signals.

The design of the wings adds exceptional strength in the gearbox stands without the use of exposed structure.

The “free wing float” slot allows the wing to float up and down without moving the hydraulic cylinder rod. This extends the life of the cylinder components.
