  • Patent number: 7367173
    Abstract: A method of controlling a greens mower, wherein the greens mower includes a motor drive system variably driving a grass cutting reel and a traction system. The method includes sensing an operating parameter, comparing the operating parameter to a predetermine parameter and outputting a control signal to the motor drive system in response thereto, and further outputting a user signal to a display member representative of the control signal to alert an operator of the operating parameter. The method may also be used to control a fleet of greens mowers using a master controller. In this regard, the master controller may include an administrator or supervisor function preventing an operator from changing any predetermined parameter.

  • Patent number: 7305811
    Abstract: A side-mount mowing attachment for a riding mower or yard tractor is removably secured to the riding mower by single hinge pin, allowing the side-mount mowing attachment to articulate and follow the ground contour independently from the primary mowing deck of the riding mower when in a lowered and operational configuration, and which may to be secured in an upright and vertical position when not in use. Power is provided to the cutting assemblies of the side-mount mowing attachment by a drive-belt and pulley assembly coupled to the primary mowing deck drive mechanism. A winch assembly facilitates lifting of the side-mount mowing attachment to the raised and upright position when not in use. When moved to the raised and upright position, tension is automatically released on the drive-belt in the belt and pulley assembly, thereby stopping the transfer of power from the primary mowing deck drive mechanism to the side-mount mowing attachment cutting assemblies.

  • Patent number: 6931828
    Abstract: A harvesting machine includes a pick-up unit for picking up the harvested crop, a cutting device that is equipped with at least one cutting edge that cooperates with a counter-cutter for cutting and/or chopping the harvested crop, and a monitoring device, which can be operated to generate a signal containing information about the sharpness of the edge and/or its distance to the counter-cutter, with the sharpness and distance each being compared to a target value. The monitoring device receives signals generated by an optical sensor, which visually monitors the cutting device and/or the cut harvested crop, wherein the signal of said sensor is used so that the monitoring device can deduce information about the sharpness of the edge and/or its distance to a counter-cutter, and send out a control signal for effecting automatic sharpening of the cutting edge and/or adjustment of the counter-cutter.
