The Strawmaster X Disc Harrow, with disc on command technology gives you the ability to cover large acres at high speeds in a large working width. Built off the impressive Strawmaster+ frame, the design allows for more tillage then a traditional heavy harrow, but less aggressive than a high speed disc.  The Strawmaster X will size residue, while still leaving some standing material to catch snow.

Discs on Command

The Adjustable angle of 0 – 15 degrees on the discs give you the ability to blacken the soil which warms up the field quicker in spring for seeding, speeds up drying on wetter years and allows material to break down over winter.

In drier years, lift the discs out of the way and use as a traditional 4 bar harrow.

Get To Work

Get in and out of the field quicker than ever before. The inboard transport/wing wheel assembly features large floatation tires (500/60-22.5) that hydraulically operate to make sure you're back to work faster than ever before. 

The Strawmaster X transport width of 12-6” and height of 13' 6" makes getting down grid roads safer and easier. The unique end wheel design follows the tractor better than traditional harrows, making it easier to turn into more narrow approaches. 


Simple Disc Harrow Design

After years of testing we have found that one row of 20” discs at 10” spacing combined with 4 bar harrow sections equipped with 30” tines (that's the same as our Strawmaster Pro) resists plugging in wet conditions and allows material to flow through the machine more freely. 

Engineered and Built Tough

At the heart of the machine are the robust 10x10 wing beams. These provide consistent beam torque and tine pressure throughout the machine, and help spread straw evenly for a more consistent field finish. 

The Strawmaster X is designed to adapt
to your unique conditions. 

Setting Indicators

There are three setting indicators on the Strawmaster X. One for cart height, one for beam torsion and one for tine angle. Knowing exactly how your machine is running is key when getting your desired field finish. 




Disc Angle Adjustments

Having the option to change the disc angle allows you to use the machine in various conditions.

0-4 degrees with a coulter disc will allow you to open the ground and cut trash with minimal soil disruption.

5-7 degrees is good for mixing some dirt with residue while loosening the soil but still leave stubble standing to catch snow.

8-10 degrees is perfect for working low spots with high trash and for drying them out.


Wave Samurai

  • Good for cutting heavy trash and mixing soil while incorporating
  • Extremely aggressive edge maintains penetration and wear
  • Fluted disc allows blade to turn in heavy residue
  • 4 to 10 degrees, can be angled more aggressively if needed


5 Wave Notched

  • Good for maximum coverage and mixing soil at shallow working depth
  • 4”wave assist disc to turn in extreme conditions
  • Notches help disc penetrate and size material
  • Maintains constant cutting angle as it wears
  • 0 to 10 degrees


Curved Wave VT

  • Good for opening ground and cutting with minimal soil disruption
  • Soil razor edge cuts aggressively with good wear characteristics
  • Curved waves allows blade to turn in heavy residue without turning soil over
  • 0 to 4 degrees, should not be angled aggressively


Flattened Double V

  • Good for cutting/sizing trash and incorporating
  • Aggressive edge maintains penetration and wear
  • Double V provides a smoother furrow
  • 2 to 10 degrees, can be used more aggressively if needed
