An accessory attachment system for a machine is disclosed. The accessory attachment system includes a housing configured to be detachably coupled with the machine. A plurality of electric connectors is disposed in the housing. The plurality of electric connectors is communicably coupled with an electrical system of the machine. The plurality of electric connectors is configured to selectively provide an electric power to one or more detachable external devices. A fluid connector is disposed in the housing. The fluid connector is in fluid communication with a hydraulic system of the machine. The accessory attachment system further includes a hydraulic device detachably coupled with the housing. The hydraulic device includes a device fluid connector configured to be fluidly coupled with the fluid connector of the housing. The hydraulic device is selectively powered by the hydraulic system of the machine.

Accessory attachment system for machine

A support structure for an implement lift cylinder on an earth-working machine. The support structure includes first and second implement lift cylinder supports. The first implement lift cylinder support mounts to the work machine and the second implement lift cylinder support rotatably connects thereto about a first axis of rotation. The second implement lift cylinder support receives the implement lift cylinder and allows rotational movement thereof about a second axis of rotation. The first and second axes are located within a single plane. The dual axes provide stability and adjustability of the implement lift cylinder for different angle configurations of a work implement, such as an earth-working blade.
