    Ben Scott - Rata Offset Discs Testimonial

    I'm impressed with the results these discs give, they contour the ground & hills while staying in the ground actually discing, even in this harder, dryer stony ground so I'm pretty pleased. Being a heavier weighted disc they bite into the harder ground really well.

    Hydraulic cut adjustment is awesome as you can adjust it on the go.

    Great product & machine!
