Heavy reversible, mounted ploughs: R71, R7 and RW7
Ploughs for high horsepower tractors
To cope with even more difficult soil types the R71, R7 and RW7 ploughs have been developed for tractors from 90 to 360hp.
These ploughs have a 150x150 mm beam and a 115 mm diameter headstock shaft made of special high grade steel. They have different security systems and clearances.
R71 - the basic version
The R71 is the basic model, it has a single mechanical adjuster and is suited to tractors with a fixed wheel width.
R7 - for use with multiple tractors
The headstock is connected to the frame via a parallelogram system. It can be used on any tractor with any wheel width.
On the R71 and R7 models the adjustment of the working width is performed manually with 6 positions (12, 14, 16, 18, 20 and 22 inches)
RW7 - for use with variable soil types
The RW7 allows the working width to be adjusted hydraulically, on the move from the cab, from 12 to 20 inches. It can be used on any tractor with any wheel width.
Large choice of options
As on other ploughs in the Grégoire Besson range there is a wide choice of wheels (depth adjusting, transporting, combined etc.) as well as mouldboards and skimmers.
