To ease work of transferring a fuel from a fuel supply tank to a fuel tank, a fuel supply guide to be used to supply the fuel by using the fuel supply tank to the fuel tank having a tank body for storing the fuel and a fuel supply port on the upper side of the tank body includes a support member provided on an upper portion of the fuel tank, and a body member projecting from the support member in a direction away from the fuel supply port as the body member extends upward and projecting higher than the fuel supply port. The body member is capable of receiving the fuel supply tank by an upper portion thereof to support the fuel supply tank.

A work machine includes a frame, a traction system, an engine, an implement system, an operator cab with a roof; a machine control system, and a secondary control system. The secondary control system is configured to interface with the machine control system and includes a secondary control device, a control module, a communication module, a base plate, and two rails. The base plate is configured to support the control module and the communication module, and protect the plurality of harness connections. The two rails are configured to support the base plate in an operation orientation and a service orientation and each include a plurality of channels configured to support the base plate in the service orientation.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a covering attached on the upper turning body, and a camera for surroundings monitoring placed on the upper turning body. A cut is formed in the covering. The camera is placed on the upper turning body such that at least part of the camera is within the covering through the cut.

A combination tie down lug and step riser includes a foot support portion, a hold down loop and a mounting portion. The combination tie down lug and step riser is preferably fabricated from a single piece of material. The foot support portion includes a plurality of projections extending upward from a top edge thereof. The hold down loop extends from one end of the foot rest portion. The hold down loop includes a U-shaped opening with the U-shaped opening positioned along a horizontal axis. The mounting portion extends from an opposing end of the foot support portion. Opposing ends of the hold down loop and the mounting portion are attached to an excavator base with welding or any other suitable attachment method.

An ECU includes a memory including computer executable instructions for monitoring the condition of a ground engaging tool, and a processor coupled to the memory and configured to execute the computer executable instructions, the computer executable instructions when executed by the processor cause the processor to: acquire an image of the ground engaging tool, evaluate the image using an algorithm that compares the acquired image to a database of existing images to determine the damage, the amount of wear, or the absence of the ground engaging tool, and grade the quality of the acquired image.
