  • Patent number: 5987785
    Abstract: A snow-plow system having four major features: lighting system, a quick and easy disconnect/connect system, a reactive controlled pressure mechanism for applying a controlled pressure to the bottom edge of the moldboard of the plow, and a simple electric control to activate or de-activate the reactive controlled pressure mechanism. The present invention may be summarized as a snow-plow system that is mounted to a vehicle having a mounting frame by an easy connect and disconnect system connecting to the A-frame of the snow-plow by use of three mounting pins which hold the snow-plow system in place on the mounting frame of the vehicle and thereby rigidly connect the system to the vehicle. A light bar or lighting system also is rigidly mounted to the A-frame of the snow-plow at the mounting pins so that once the position of the lighting system is determined the relative position of the lighting system with respect to the vehicle does not change.

  • Patent number: 4092004
    Abstract: An agricultural feed grinder and mixer having a hammermill means which grinds various types of grain and other feed and combines the ground crop material with supplemental feed and thoroughly mixes the combination and discharges it to other containers or storage areas. The machine has a generally horizontal feed screw auger which receives the material from the hammermill and from the supplemental feed hopper and discharges it into a mixing tank. Power is transmitted from a power source, such as a tractor through a power take-off shaft and through the feed screw auger where the power is delivered to a mixing auger in the mixing tank.
