ABSTRACT:
A track type work machine is provided including a roller frame having a rotatable idler mounted at an end thereof. A gas spring is operable to absorb selected loads on the idler, and is isolated from loads transverse to a reciprocation axis of the gas spring by a recoil system. A method of providing for load absorption from the idler is also provided. The method includes positioning a gas spring between the idler and a roller frame of the work machine, and operably coupling the idler to the gas spring to selectively transmit loads from the idler thereto.
