Don't ForgetFinance enquiry
The MAMMUT rotary harrow has been designed to meet the demands of large farming companies and third-party contractors. Excellent results are obtained both on ploughed land and hard soil with a low rate of crop residue. Blade shaft couplings on tapered roller bearings matched face-to-face on the bottom part of the gearbox. The different components are opened and closed by 4 hydraulic cylinders supplied standard across the entire range, offering improved stability and sturdiness during works.
