Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

A height-adjustable track drive system for an agricultural vehicle includes a support frame having four fixed-length links, each link rotatably coupled to two adjacent links at pivot points. Four wheels are connected to the support frame, and each wheel is connected to the support frame at one of the pivot points. A hydraulic cylinder connects nonadjacent pivot points of the support frame. An endless track rollably contacts each of the four wheels, and one of the wheels includes a drive wheel configured to be connected to a chassis of the agricultural vehicle. Related agricultural vehicles and methods are also disclosed.

A track assembly for providing traction to an off-road vehicle, such as an agricultural vehicle, a construction vehicle, or another work vehicle, in which the track assembly may comprise a suspension between a frame of the track assembly and a bogie carrying roller wheels of the track assembly.

A dive-resistant suspension for a snow machine having a ski assembly and a body has a swing arm and a resilient member that biases the swing arm downward relative to the body. The swing arm has a first rigid linkage and a second rigid linkage. The first rigid linkage has a first pivot point connected to the body of the snow machine and a second pivot point connected to the ski column. The second rigid linkage has a first pivot point connected to the body of the snow machine and a second pivot point connected to the ski column. The swing arm defines a travel path of the ski assembly as the swing arm moves between an operative position and a retracted position. In a first portion of the travel path, the ski assembly moves from the operative position forward and up relative to the body of the snow machine.

A crawler traveling device includes a first wheel; a second wheel spaced from the first wheel; a support frame that supports the first wheel and the second wheel; a third wheel disposed above the support frame; an endless crawler wound around the first wheel, the second wheel, and the third wheel; and a vehicle-height changing mechanism that changes a position of the support frame in the vertical direction with respect to the third wheel. The vehicle-height changing mechanism has an actuator that is capable of contracting in the vertical direction and that changes the position of the support frame in the vertical direction with respect to the third wheel.

A guard assembly is provided for use with a track assembly for a vehicle. The guard assembly includes a guard body having a rigid portion made of a first polymeric material and a flexible portion made of a second polymeric material different from the first polymeric material. The first polymeric material has a greater modulus of elasticity than the second polymeric material. A vehicle including a guard assembly, namely including a guard body is also contemplated.
