Semi-mounted, reversible ploughs: SPER7, SPERW7

light mounted reversible plough

Simple performance

These ploughs have a 150x150 mm main beam expanding to 200 x 150 mm after the headstock. They have different security systems and clearances available.

Each model is suitable for 70 to 220 horsepower tractors.

Tight turning circle

The articulated headstock provides a 110 degree turning circle. The turnover at the headland is controlled via 2 rams.

SPER7 - manual working width adjustment

On the SPER7 the adjustment of the working width is performed manually with 6 positions (12, 14, 16, 18, 20 and 22 inches)

SPERW7 - variable working width

The SPERW7 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.
