A new angle on speed disc technology

Get more efficiency and productivity with the Opti-Cut angle.

The ExpressPlus range from FarmChief uses 560mm discs with 21° cutting angle and a 19° vertical tillage angle. These angles give the disc an aggressive cut into the soil whilst providing the penetration needed to work the ground effectively. 

Over time, a disc blade will naturally become smaller, and its cutting edge will wear down with use. On some speed disc designs, this wear can change the effective working angle of the blade and gradually cause them to lose their ability to cut, lift and incorporate soil the way they did when they were new.

The ExpressPlus has been designed differently. The angle of the disc and the way it’s positioned on the machine work together so that the working angle remains consistent as the disc wears. 

This means the disc isn’t relying solely on a sharp, barely worn edge to provide its cutting action. The geometry of the disc is designed to maintain its working angle throughout the life of the blade, ensuring performance consistency does not degrade as quickly over time.

Also, unlike most speed discs, the ExpressPlus uses a cone shaped disc, rather than a conventional concave design, the cone shape creates a consistent point to point from the bearing position to the edge of the display, which is important for maintaining that all important working angle.
