A work machine may include an drive frame, a drivable track coupled to the drive frame, an idler wheel coupled to the drive frame to facilitate movement of the drivable track, and a wheel weight coupleable to the idler wheel. The wheel weight may be coupled to the idler wheel without removing the idler wheel from the drive frame.

A track roller assembly may have a track roller, a roller shaft and collars press fit onto either end of the roller shaft to retain the track roller on the roller shaft with an axial clearance between the collars and the track roller. During assembly, the collars may be press fit onto the shaft ends and forced axially inwardly until further axial movement of the collars is prevented by engagement shoulders of the track roller. A compressive axial load may be applied to the roller shaft to reduce a shaft length of the roller shaft and to cause the roller shaft to slide inwardly relative to the collars. The compressive axial load is removed from the roller shaft so that the roller shaft extends back to the normal shaft length and the collars move axially farther apart as the roller shaft extends back to the normal shaft length.

Provided is a lightweight crawler unit which is capable of swiveling, suitable for a trolley for bad roads, and used for transportation in muddy places such as snowy roads, sandy ground, and fields, and disaster sites. A crawler includes a plurality of inner attachments provided inside thereof toward a frame to have a band-shape, overhang edges 70 protruding in a left and right direction of a rail provided on a circumference of the frame, and overhang edges 34 protruding in a left and right direction of each of the inner attachments, in a space K enclosed between the overhang edges 34 facing each other, the overhang edges 70 are inserted, the overhang edges 34, 70 are set in a positional relation in which they overlap with each other in an up and down direction, and the crawler circulates around pulleys, while the inner attachments are restricted along the rail.

A fluid level monitoring system for a container defining a chamber includes first and second flexible interdigital capacitive sensors located at first and second ends of the chamber and disposed about a longitudinal axis of the chamber. The first and second flexible interdigital capacitive sensors are configured to be immersed, at least in part, within a fluid contained in the chamber. The fluid level monitoring system further includes a controller disposed in operative communication with the first and second flexible interdigital capacitive sensors, to determine a level of the fluid in the chamber based, at least in part, on an average of measure of parameters received from the first and second flexible interdigital capacitive sensors.

A tractor includes a frame including an axle, the axle including an axle shaft and a beam member. A cab is mounted to the frame, the cab including controls for controlling the tractor. A ground-engaging mechanism coupled to the axle, the second ground-engaging mechanism including a track assembly. The track assembly includes an undercarriage assembly, a carrier housing, a ring gear, and a track, where the carrier housing includes a pivot arm for pivoting coupling to the undercarriage assembly. The ring gear defines an outer diameter, and the axle shaft and beam member are adjustably coupled to the carrier housing at a location inside the outer diameter.

A bag is disclosed for covering an endless track or chain of a tracked heavy equipment vehicle during transport. The bag includes an outer segment for covering an outer portion of the track extends laterally beyond side edges of the trailer flatbed. Forward and rearward lobes of the bag, respectively engage and cover forward and rearward ends of the track. An inner bag segment engages and covers the track between the side edges of the flatbed trailer supporting the tracked vehicle. A recess in an inside segment of the bag accommodates a track and allows the track to directly engage the supportive trailer. Tensioning straps and cords are used to further secure the bag to the track.
