US Patent 12024854 Excavator blade cylinder

Disclosed embodiments include power machines with a lower implement pivotally coupled to an undercarriage frame by a lower lift arm structure and which include one or more cylinders or actuators that are operable to pivot the lower lift arm structure and lower implement relative to the undercarriage frame. A configuration of the one or more cylinders which mounts the cylinders behind the lower implement, with attachments to the undercarriage and to the lower lift arm structure at positions which allow the cylinders to be surrounded and protected by the undercarriage, reduces damage to the cylinders during operation.
