Heavy-duty cutterbar for the toughest cutting conditions

Rotary disc cutterbar  Rotary disc cutterbar

A multi-V-belt drive system transfers power from the gearbox to each rotary disc.

 

Power is transmitted to the rotary discs through fully enclosed gears running in oil for a quiet, smooth, reliable operation.

Convenient belt adjustment location (R240, R260, R310) Convenient belt adjustment location (R240, R260, R310)

All models have a spring-loaded belt tensioner for easier belt adjustment. The belt tension automatically compensates for initial belt stretch, increasing belt life.

High-speed rotary discs High-speed rotary discs
#

Rotating at 2986 rpm, the high-speed discs cut in the toughest conditions.

The low-profile cutterbar allows a close cut while maintaining a level cutterbar. The cutting height is controlled by adjusting the tilt of the cutterbar.

Each disc has two free-swinging knives:

  • Easy to remove and replace
  • Two cutting edges, doubling the use life

Easy-to-attach 3-point hitch tractor hookup

Easy-to-attach 3-point hitch Easy-to-attach 3-point hitch

The R240, R280, and R310 Mowers attach to tractors with a Category 2 3-point hitch and all three models are quick-hitch compatible.

The R240, R280, and R310 models have a built-in parking lock that holds the 3-point arms up, making tractor hookup quick and easy.

Adjustable lower hitch pins Adjustable lower hitch pins

Lower hitch pins can be adjusted left or right to match the mower offset for tractors with wider tire spacing.

 

The R240, R280, and R310 models have an offset range of 105 mm (4 in.).

Optional long hitch pin Optional long hitch pin

Adjustable lower hitch pins and an optional longer hitch pin allow for use with tractors of various tire spacing.

 

Available through Parts: an optional long hitch pin increases mower offset to 200 mm (8 in.) for tractors with even wider tire spacing.

Adjustable lower hitch pins and an optional longer hitch pin allow for use with tractors of various tire spacing.

Rearward-swinging hydraulic cylinder

Two extra hydraulic hoses for rearward-swinging cylinder Two extra hydraulic hoses for rearward-swinging cylinder

The R240, R280, and R310 models offer an optional rearward-swinging hydraulic cylinder. The optional hydraulic cylinder allows the operator to swing the mower away from the tractor, eliminating the need to fold up the protective curtain when putting the mower in transport.

 

Mowers with this option have two additional hydraulic hoses that control the hydraulic cylinder that swings the mower away from the tractor.

 

NOTE: The optional rear-swinging hydraulic cylinder will be available through Parts.

Heavy-duty driveline with overrunning clutch

A heavy-duty driveline with overrunning clutch is standard equipment on R240, R280, and R310 Mowers.

 

All mowers are equipped with a shielded, pullback-collar, telescoping power take-off (PTO) driveline.

Onboard storage compartment

The R240, R280, and R310 models are standard equipped with an easy-to-access, built-in storage compartment. This convenient drawer is a perfect place for extra hardware such as nuts, bolts, and replacement knives.

Easy-to-remove disc quill

The cutterbar is protected from severe impact should an object be struck.

  • Disc drive-shaft shears
  • Reduces chance of internal damage to cutterbar
  • Improves cutterbar reliability

Disc quills are easily removed from the top of the cutterbar for improved serviceability.

 

Each disc has two free-swinging knives:

  • Easy to remove and replace
  • Two cutting edges, doubling the use life
  • Swings away to reduce possible damage if a solid object is struck

Lift and suspension system

Heavier floatation spring controlling ground pressure Heavier floatation spring controlling ground pressure
#

A lift and suspension system allows for the R240, R280, and R310 models to raise the cutterbar off the ground without raising the tractor’s hitch.

 

The disc mowers use the hydraulic cylinder to lift the cutterbar from the cutting position to the transport position, and the cutterbar automatically locks into place.

 

A longer cylinder on the R240 and R280 allows for a cutting arc of +35 degrees to -25 degrees. A longer cylinder on the R310 allows for a cutting arc of +35 degrees to -30 degrees.

 

A heavier spring establishes even flotation along the full length of the cutterbar in a variety of different field conditions and topography.
