Schulte FX-1800 Rotary Cutter

Legendary Schulte toughness at an economical price.

Schulte Cutters are renowned for being the toughest and most dependable slashers on the market. The FX-318 continues this tradition at an economical price, making it an excellent choice for slashing crop residue, pastures, weeds, orchards, plantations, and roadsides. Schulte owners appreciate the high-performance features of their cutter:

  • A single domed 7-gauge continuously welded deck offering many benefits:
    • It is extremely easy to clean,
    • The dome prevents water pooling and rusting,
    • It helps shed debris as you cut, and
    • Weighs less than double decks.
  • An ultra-narrow transport width and over-centre wing fold makes moving this unit extremely safe and simple to move between work and transport modes. 
  • Available with 540 RPM or 1000 RPM with 80° CV drive or 540 equal angle non-CV drive at the same price.
  • The four-gearbox drive line is protected with easily accessible, self-adjusting independent slip clutches. Our drivelines utilise the latest heavy-duty and extremely reliable Bondioli gearboxes with oil level sight glass on the rotor boxes for convenient maintenance checks.
  • A one-piece centre shield allows for easy and full access to drivelines, clutches, and gearboxes on the centre section.
  • The power divider has 1¾” 20 spline input and output shafts and is rated at 260 HP. The centre and wing boxes have 1¾” 20 spline input shafts, 2⅜” down shafts and are rated at 210 HP.
  • 80° CV shaft allows for smooth power transmission during tight turns.
  • The 540 RPM cutter has a Category 6 shaft, and the 1000 RPM has a Category 5.
  • 6 mm x 100 mm deck protection rings protect the deck from blade impact.
  • Spun formed 7-gauge stump jumpers (round skid pans) ensure durability and balance. Optional Fixed Knife T-bar mulching kit available.
  • Schulte Industries exclusive Pentagon Blade Bolt provides maximum anti rotational resistance where the blade is fastened to the stump jumper pans.
  • Standard with Super Suction 1/2" x 4” blades that leave nothing behind. Schulte blades are strengthened through a hardening process which increases the impact strength of the blade. The blade is chamfered around the blade bolt hole to provide a smooth transition of surfaces around the high stress blade bolt area. The blades are also shot peened to induce beneficial compressive surface stresses over the entire length of the blade. This enhances the durability and extends the fatigue life of the blade. The cutting edge is forged giving it a stronger and tougher edge thereby extending the life of the blade.
  • Optional mulching blades available.
  • Deep side skirts, extended blade overlap and high blade tip speeds for the best cutting performance and material flow.
  • Wing working range from -25° to 90°.
  • Safety first with single chains and half rubber flaps front and rear and durable driveline covers.
  • The centre and wing wheel standards are constructed from heavy duty large 5 9/16" O.D. x 3/8" thick HSS round tubing.
  • Extremely strong and durable 517 hubs and spindles with built in metal seal guards allow this cutter to tackle any type of terrain.
  • Six puncture-proof laminated or heavy-duty forklift tyre options.
  • Greaseable hinge line turnbuckles help to reduce wear and aid in long life of the cutter’s parallel lifting mechanism.
  • All pivot points use 1" greaseable pins.
  • Two-piece replaceable skid shoes made from 10 mm thick abrasion resistant steel.
  • Schulte has many hitch options including clevis hitch, an adjustable clevis, precision hitch or solid tongue to help create a better fit & reduce wear on your tractor's drawbar.

The FX-1800 features floating wings to allow slashing of embankments and undulating ground.

Hydraulic ball-lock to prevent wings opening in transport.

Mounted on the centre deck, the lock up system prevents the cutter from lowering during transport and storage.

Fitted with optional mulching blades, the FX-1800 can cut paddock stubble loads before planting, aiding in moisture retention.

FX-1800 Side Eject Option

Our side eject option has been designed in Australia for plantations, orchards and horticulturalists requiring cut material to be spread under trees as a mulch layer. The system features an adjustable exit chute to control how far cut material is thrown. When not used as a side eject cutter, the chute is removed and replaced with a side skirt shield to meet safety regulations. The side eject option is available now and made to order.

An FX-1800 fitted with side eject powering through tall tropical grasses.

The adjustable side eject chute give control over material throw.

Side ejection can be fitted to either or both wings.

Side ejection is usually paired with mulching blades for finer cutting of grass and a better mulch layer.
