Title: Snow blade with tiltable lateral panels
Inventor: DESMARAIS DENIS
IPC: E01H5/06
Filed: 1997-06-18
Granted: 2003-03-18
Abstract: A snow plow composed of a central blade and of two wing blades which are laterally hinged to the end of the main blade for wing blade angular adjustment forwardly and rearwardly of the main blade from a position and alignment with the same. Furthermore, the level of each wing blade with respect to the main blade can be adjusted. Also, tilt motion of the laterally outward end portions of the wing blades either upwardly or downwardly is also possible. Each blade consists of a flat panel and its bottom edge carries a striker lip which can pivot rearwardly during forward movement of the plow upon the blade striking an obstacle. The snow plow is supported by a structure in front of a vehicle having forward lifting and tilting arms, this structure allowing a snow plow to laterally tilt within a limited angle in accordance with the transverse inclination of the surface being plowed. Upon slight rising of the snow plow, its forward pitch angle automatically increases to a pre-determined limit.

Abstract: A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system. Load sensing hydrostatic drive systems can encounter vibrational or surging problems, particularly when flow compensators in valving interact with the flow compensator of the hydraulic pump. This interaction will cause rhythmic flow pulsations or surging within the hydraulic system, which is undesirable. Stabilizing the hydraulic system can be accomplished with an attenuator/hose assembly.
