PROFORGE INVERTAMAXPRO Heavy Speed – Disc Harrow Cultivator, 5 metre


Our Flagship Heavy Duty Cultivator, the latest and largest disc harrow in the range developed from our INVERTA and INVERTAMAX machines.


This is a very good option for farmers choosing ploughless tillage, as the machine offers the best cover and mixing of crop residues, even at low working depths.


The three-part machine frame allows for better distribution of the weight on the machine. The pressure on the drawbar is lower, thus the forces affecting the tractor linkage are significantly reduced. This reduces wear and tear on machinery, even in operation of a heavy disc harrow such as this one.


“My Father has farmed here since 1964. We’ve tried a number of brands over the years and these are the best set of discs we have ever had. Does everything it says on the tin. We’ve been running at 15kph and we’re on heavy land. Worked in wet and dry weather. Can’t praise it enough.”’
