Abstract
Abstract A lift and breakaway mounting assembly for connecting an implement to a prime mover includes a laterally mounted hinge plate with a spring case. The plate is pivotal with respect to the prime mover, and the case is pivotal with respect to the plate. An implement mount is operatively associated with the case by a heavy spring, whereby the implement mount is yieldably secured to the case and plate.

Claim 5
Dependent Claim
321 words
A mounting assembly for connecting a mower having a housing to a prime mover having a side subframe, the assembly comprising: a mounting plate secured to the prime mover subframe; a substantially rectangular shaped hinge plate, having an inboard end and an outboard end and terminating at its outboard end in laterally spaced portions defining a gap therebetween; bracket plates fixedly secured to respective hinge plate portions; means for pivotably supporting the inboard end of said hinge plate to said mounting plate for pivotal movement about a horizontal axis; a pair of extensible and retractable hydraulic cylinder means positioned adjacent said hinge plate, each fixed at one end to one of said bracket plates and at the other end to said mounting plate for pivotal movement with respect to said mounting plate and for extension and retraction to effect pivotal movement of said hinge plate about said horizontal axis, said extensible and retractable hydraulic cylinder means applying extension and retraction forces equally to said hinge plate on each side thereof; a spring case having stub axles projecting from the side wall thereof; bearing means carried by said bracket plates for rotatably supporting said stub axles and permitting said spring case to pivot about a horizontal axis defined by said stub axles; extensible and retractable hydraulic cylinder means pivotally connected to said hinge plate and to said spring case to effect pivotal movement of the case about said horizontal axis with respect to the mounting plate; an implement mounting member including an outer vertical plate and spaced horizontal plate disposed within the spring case; and a heavy duty coil spring operatively coupled to said spring case and said implement mounting member for maintaining the implement mounting member at a given angular position relative to said spring case but permitting rotation of said implement mounting member about a vertical axis passing through said spring case in opposition to the bias of said spring.
Claim 6
Dependent Claim
