A working machine is provided, which includes a prime mover, a first traveling pump driven by power of the prime mover to supply operation fluid through a connector fluid tube, a traveling motor including first and second ports connected to the connector fluid tube, the traveling motor configured to be switched in a first speed and a second speed higher than the first speed, a first pressure detector to detect first traveling-pump pressure near the first port, a second pressure detector to detect second traveling-pump pressure near the second port, and a controller configured, with the traveling motor switched in the second speed, to automatically shift down the traveling motor from the second speed to the first speed, when a differential pressure between the first traveling-pump pressure and the second traveling-pump is equal to or more than a deceleration threshold.

A travelling frame of a travelling device positioned between a center frame and a travelling motor attachment portion includes an upper plate extended toward the center side of the vehicle to form an extended portion. A long hole into which travelling motor hydraulic piping is inserted is formed in the upper plate along the extended portion. The travelling motor hydraulic piping extends from a lead-out hole opened in an end plate of the center frame, through the long hole of the upper plate and a long hole opened in an end plate, and inserted into the travelling motor attachment portion.

An undercarriage clearance system includes a datastore containing undercarriage geometry data including ground clearance data of the undercarriage assembly across a lateral dimension of a wheelbase of the work vehicle; a first sensor configured to collect ground environment data within the vehicle trajectory; and a controller. The controller is configured to: receive the undercarriage geometry data from the datastore; receive the ground environment data from the first sensor; identify an obstacle within the vehicle trajectory; evaluate a height of the identified obstacle and a projected path of the obstacle within the wheelbase of the work vehicle along the vehicle trajectory relative to the undercarriage geometry data to determine an obstacle clearance expectation; and generate an alert command signal based on the determination of the obstacle clearance expectation. A display device is configured to render a display based on the alert command signal representing the obstacle clearance expectation.

Utility vehicle power machines with a frame, single left and right side tracks or tractive elements, a cab, a box supported toward the rear of the frame, and a lift arm supported toward the front of the frame. The utility vehicle power machines can have removable covers on a front of the frame, forward of the cab to provide access to various components.
