Schulte FX-520 Rotary Cutter 

Unsurpassed cutting performance from a 5-rotor 20’ cut, the best 20’ cutter in Australia

Schulte Cutters are renowned for being the toughest and most dependable slashers on the market. The FX-520 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.
  • A narrow transport width makes moving this unit extremely safe. 
  • 1000 RPM with 80° CV drive in 1⅜” 21 spline or 1¾” 20 spline at the same price.
  • The five-rotor design optimises cutting performance, increases productivity and delivers extremely even distribution over competitors three-rotor 20' models.
  • Unique 6 gear box layout, 260 HP divider box, 190 HP down boxes, 1000 RPM driveline gives unsurpassed cutting performance with higher cut speeds. 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.
  • The low maintenance drive line is protected by 5 slip clutches, 1 at each down box, and a shear pin at the input shaft on the divider box.
  • 80° CV shaft allows for smooth power transmission during tight turns.
  • 6 mm deck protection rings protect the deck from blade impact.
  • Spun formed 7-gauge stump jumpers (round skid pans) with single updraft blades or Fixed Knife T-bar mulching kit at the same price. Mulching blades are available as an option on pan configurations.
  • 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.
  • Hitch Lift Assist helps to lift the mower over obstacles to prevent undue stress on blades and down shafts.
  • 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°.
  • Hydraulic phasing cylinder system ensures an accurate parallel lift across the cutter.
  • Safety first with single chains and half rubber flaps front and rear and durable driveline covers.
  • Extremely strong and durable hubs and spindles with built in metal seal guards allow this cutter to tackle any type of terrain.
  • Standard with single wheels on centre deck and wings (as pictured above). Dual  wheels/walking beam axles optional.
  • Wheel spacings are adjustable to suit row crop applications.
  • All pivot points use 1" greaseable pins. Steel spring bushes at all vital pivot points.
  • 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.

Aussie units come standard with row crop tyres. Other tyre configurations available.

The 5 rotors give unsurpassed performance over 3 rotor models.

Exclusive patent pending Pentagon Blade Bolt design makes for easy fitting and removal of blades.

Schulte's super suction blades pull up material in tractor wheel tracks.

Mulching blades and Schulte's exclusive Fixed Knife technology combine for superior stubble mulching results.

Mulching blades push material through the fixed knife resulting in a finer cut.

FX-520 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.

The FX-520 at work 

These two videos were shot on a dairy in southern Victoria. The FX-520 is on it's start-up run. It is fitted with the optional mulching blades to give a finer finish and will be used for pasture topping to maintain required pasture growth rates.

This FX-520 is on it's maiden run at Wallendbeen NSW. It is fitted with the fixed knife T-bar mulching kit for stubble work, but you can see it does an excellent job topping lucerne.

The FX-520 is used by airports across the country and around the world for maintaining grass around runways. Here are two units at work at Washington Dulles Airport. Video courtesy of Schulte Industries Ltd.

And if it's just weeds you want to cut, the FX-520 is up to the task. Video courtesy Schulte Industries Ltd.
