Abstract: Track systems for traction of a vehicle in which a spacing of laterally-adjacent ones of the track systems in a widthwise direction of the vehicle is adjustable. This may facilitate use of the vehicle in different conditions (e.g., in different field configurations, such as in different configurations of row crops, where the vehicle is an agricultural vehicle). For instance, the spacing of the laterally-adjacent ones of the track systems may be adjustable while the laterally-adjacent ones of the track systems are connected to a powertrain of the vehicle and/or without requiring use of additional parts (e.g. spacers).

Abstract: A track system for traction of a vehicle (e.g., an agricultural vehicle) in which the track system is designed to better perform when the vehicle is roading, travelling on a side hill or other inclined surface, is braking or undergoing other rim pull events, and/or in other situations, such as by enhancing load distribution (e.g., with wheels that can laterally oscillate and be wider) and/or track tensioning (e.g., with different tensioning stages).

Abstract: A ratchet system for winding a rolling door assembly. The ratchet system includes a support bracket, a cam, and a biasing device. The support bracket is preferably mounted onto a fixed structure of the rolling door assembly. The cam is pivotally mounted about the support bracket and positioned adjacent to a portion of an overhead shaft of the assembly. The cam is shaped and sized to cooperate with this portion of the overhead shaft between a first position, where the cam allows rotation of the overhead shaft along a first direction, and a second position, where the cam has a surface engaged with the overhead shaft and where further rotation of the overhead shaft along a second direction, opposite to the first direction, is blocked by the cam. The biasing device is used for urging the surface of the cam onto the overhead shaft. The ratchet system is particularly useful for adjustably controlling the rotation of the overhead shaft of the rolling door assembly during the winding thereof.

Abstract: A watercraft bumper has an elongate body. The elongate body has a generally C-shaped cross-section. A protrusion extends from one of the end portions of the cross-section and extends towards the other end portion. A watercraft having the bumper is also disclosed. The watercraft has a lip over which the bumper is disposed. The lip has a depression formed in an upper side thereof. The protrusion of the bumper is disposed in the depression and is biased against the upper side.

Abstract: A ratchet-like system for winding a rolling door assembly. The ratchet-like system includes a support bracket, a cam, and a biasing device.
