Like the RC31 plough, these ploughs have a 120x120 mm beam and a 100 mm diameter headstock shaft made of special high grade steel.  They have, however, different security systems and coulters for different functions.

Suitable for 70 to 150 horsepower tractors, each model filfuls a specific need.

R41: for lower horsepower tractors
The R41 is the basic model, it has a single two position mechanical adjuster and is suited to tractors with a fixed wheel width.

R4: for use with multiple tractors
The headstock is connected to the frame via a parallelogram system which gives complete setup freedom. It can be used on any tractor available on the farm with any wheel width and is easily adjusted for ploughing widths from 12 to 20 inches.
