A larger “beefed up” model, the 750 gives you everything the 730 offers with additional durability.

Cutting 7.3 metres at speed, the 225HP gearbox is always one step ahead. And five rotors eat into your stubble in whistlestop time. Half the blades are angled to achieve a double cut, flaring the chopped material to mix with soil dust before spreading evenly.

This is a heavy-duty Hardox steel-decked machine you can depend on. Backed by our 7-year gearbox warranty, this unit takes rotary mowing to the next level.

  • A heavy-duty wide area machine.
  • 225HP driveline for additional power.
  • Hard wearing specification.
