Each disk gang can be adjusted individually without tools for ease of use. This allows precise disk angle settings to match different soil conditions. The mismatched front and rear gang angles enable straighter tracking for a smoother finish.

Notched front blades come standard on the TM12 Tandem Disk Harrow, providing an aggressive cut for different material sizes. The rear blades, available in smooth or notched, allow for better soil control, deeper tilling depths, and improved soil penetration.

A scraper kit (as pictured) is available to improve disk blade performance by removing soil buildup from disk blades in wet, sticky soil types with the scraper kit. The Furrow Filler Kit provides additional smaller-diameter disk blades to mount onto the outermost rear disk gangs, helping to fill in the furrow and eliminate ridging that can be created by the outermost disk blade.
