Features
Variety of Disk Blades for Optimal Performance

The TM14D offers multiple blade configurations like notched and smooth blades for diverse soil conditions. It supports 7.5-in. or 9-in. (19-cm or 23-cm) spacings, providing flexibility in seedbed preparation and effective residue handling, suitable for various soil types.
Disk Depth and Leveling

Disk depth and leveling are managed manually with crank adjustments. The depth control crank modifies how deep the disks penetrate, while the front-to-rear leveling crank prevents ridges, ensuring a smooth finished field surface.
Easy Disk Gang Adjustments

This harrow allows simple gang angle adjustments with an ergonomic pin design. Operators can change the angle for optimal soil penetration or smoothing, adapting efficiently to different residue levels and soil conditions without tools.
