Abstract
A V-shaped pull type rake composed of a wheeled transversal element having a tow member extending longitudinally therefrom and a pair of rake arms attached at substantially each end of the cross member. The rake arms are moveable between an open position and a closed position. Each rake arm is provided with a double-acting hydraulic cylinder which is attached at one end to the tow member and at the other end to the rake arm and serves to move the rake arm to which it is attached to a position between (and including) the open and closed positions and all incremental positions therebetween.

A "V" shaped pull type rake comprising:
- a cross member having a right end and a left end;
- a tow member attached to the cross member at a point between the right end and the left end of the cross member and extending longitudinally therefrom;
- a first rake arm having a front end and a back and and pivotably mounted at its back end to the cross member at a point between the tow member and the right end of the cross member so as to be moveable between an open position and a closed position;
- second rake arm having a front end and a back end and pivotably mounted at its back end to the cross member at a point between the tow member and the left end of the cross member so as to be moveable between an open position and a closed position;
- a plurality of rotatable rake wheels mounted on each of the first and second rake arms;
- and
- a first and a second double acting hydraulic cylinder, the first hydraulic cylinder having a first section connected to the tow member and a second section connected to the first rake arm, and the second hydraulic cylinder having a first section connected to the tow member and a second section connected to the second rake arm;
