Lawn mower attachment for small tractors

A lawn mower attachment for a tractor of the type having front and rear wheels and a rotary mower blade mounted between the front and rear wheels, comprising;

• a central frame having a universal pivotal connector at the forward end thereof adapted for connection with the tractor so that the tractor pulls the frame, unpowered wheel means supporting and mounted at the rear end of the frame, a first rotary mower element pivotally supported on one side of the frame about a horizontal axis generally parallel to the path of travel, a second rotary mower element pivotally supported on the other side of the frame about a horizontal axis generally parallel to the path of travel, so that the first and second mower elements will cut a path on both sides of the path cut by the tractor mounted mower blade, a motor unconnected to the wheel means carried by the frame means for driving both of the first and second mower elements, and separate drive means connecting said motor to drive each of the first and second mower elements.

A lawn mower attachment for a tractor of the type having front and rear wheels and a rotary mower blade mounted between the front and rear wheels, comprising;

• a central frame having a universal pivotal connector at the front end thereof adapted for connection with the tractor so that the tractor pulls the frame, unpowered wheel means supporting the rear end of the frame, a first rotary mower element pivotally supported about a horizontal axis extending in the path of travel on one side of the frame, a second rotary mower element pivotally supported about a horizontal axis extending in the path of travel on the other side of the frame so that the first and second mower elements will cut a path on both sides of the path cut by the tractor mounted mower blade, a first hydraulic actuator for raising and lowering the first mower element, a second hydraulic actuator for raising and lowering the second mower element, and hydraulic control means for selectively porting fluid to the first and second actuators to either simultaneously raise and lower the mower elements or to independently raise and lower the mower elements.

A mower attachment for a small tractor having a power drive mower blade, comprising;

• a mower, a central frame adapted to be pivotally attached to and pulled by the tractor, a universal connection at the forward end of the frame adapted to be connected to the tractor drawbar, unpowered wheel means supporting the rear end of the frame, a first mower element pivotally connected to one side of the frame, a second mower element pivotally connected to the other side of the frame, wheels supporting each of said mower elements, a motor mounted on the frame and drivingly connected to the mower elements, and drive means driven by the motor and connectable to the tractor mower blade to reduce the load on the tractor motor, said drive means including an input shaft adjacent and driven by the motor and an output shaft driven by the input shaft and spaced from the input shaft a distance therefrom further than the universal connector at the forward end of the frame is spaced from the input shaft.
