Disk Blades for a Variety of Conditions
Notched Front Blades come standard on the TM12 Tandem Disk Harrow, delivering an aggressive cut and size of material.
Rear Blades are available in two different configurations:
Smooth Rear Blade
The smooth rear blades offer better control of soil for light to medium soils, slicing and mixing residue and reducing clumps for a finer field finish.
Notched Rear Blade
The notched rear blade is ideal for heavy to medium conditions and provides excellent soil penetration, which enables a deeper tilling depth in tough soil conditions delivering a more aggressive cut.
Disk Blades come with 9” spacings to promote deeper tilling depths and aggressive cuts, while allowing material to easily flow through in between disk blades resulting in consistent job quality.
Gang Angle Adjustments Made Easy
Each disk gang on the TM12 can be adjusted individually from outside of the frame.
Toolless gang adjustments improve operator ease by eliminating the need to reach into the middle of the frame for disk gang adjustments. Easier adjustments will make it more convenient to precisely set the disk angle to match changing soil conditions and the desired finish. Use a more aggressive angle to tear up and penetrate rough and uneven soil or reduce the angle for smoother final seedbed preparation.
In addition to the individual gang adjustments, the TM12 front and rear gang angles are mismatched to enable straighter tracking in the field for a smoother finish.
Scraper Kit to Remove Soil Buildup
Improve disk blade performance by removing soil buildup from disk blades in wet, sticky soil types with the Scraper Kit.
