A controller may receive, from a sensor device of a machine, machine drivetrain data indicating a load, on a drivetrain of the machine, over a period of time. The controller may detect, based on the machine drivetrain data, one or more occurrences of a decrease in the load during the period of time. The controller may determine that the one or more occurrences, of the decrease in the load, are unexpected. The controller may detect wear of a component of an undercarriage of the machine based on determining that the one or more occurrences, of the decrease in the load, are unexpected. The controller may cause an action to be performed based on determining the wear of the component.

A traveling apparatus that can be moved in two directions includes a body 1, a pair of crawler units 5, crawler actuators 40 and rolling actuators 60. The crawler units 5 are supported by the body 1 such that the crawler units 5 are rotatable about a rotational axis L1. The traveling apparatus performs crawler moving in a direction of the rotational axis L1 by the crawler actuator 40 driving pairs of crawler structures 20A, 20B of the crawler units 5. The traveling apparatus performs moving by rolling in a direction orthogonal to the rotational axis L1 by the rolling actuator 60 making the crawler units 5 roll about the rotational axes L1. To prepare for the crawler moving, the crawler units 5 are made to roll to take a movable attitude based on attitude information of the crawler units 5 from rotary encoders 72.

A track support member and drive assembly are disclosed. The drive assembly includes the track support member, an axle housing, driveshaft, hub, drive wheel, track drive frame, rollers and track. The driveshaft extends through the axle housing. The track support member is connected to the axle housing, and the driveshaft extends through the track support member. The hub rotates with the driveshaft, and the drive wheel. The drive frame is connected to the track support member, and the rollers are connected to the drive frame. The track is connected to the drive wheel and rollers. Rotation of the driveshaft rotates the hub and drive wheel which rotates the track about the drive wheel and rollers. The track support member can be a single integrated piece including an attachment ring for connecting to the axle housing, and undercarriage support arm(s) for connecting to the track drive frame.

A crawler device 2 includes a crawler unit 5. The crawler unit 5 includes a first support 10 extending along a first rotational axis L1, a pair of crawler structures 20A, 20B mounted on the first support 10 and a pair of ground contacting structures 30A, 30B mounted on the first support 10. The pair of ground contacting structures 30A, 30B are arranged outside of the pair of crawler structures 20A, 20B in a direction in which the pair of crawler structures 20A, 20B are opposed to each other. The crawler unit 5 is supported by second supports 41, 42 such that the crawler unit 5 is rotatable about the first rotational axis L1. An outer periphery of the crawler unit 5 having a circular cylindrical configuration includes first zones Z1 occupied by the pair of crawler structures 20A, 20B and second zones Z2 occupied by the pair of ground contacting structures 30A, 30B alternately arranged in a circumferential direction.

A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve ?(x)=4.641e.sup.0.34x. The value x represents a horizontal direction and the function f(x) represents a vertical direction.
