Abstract
In a mowing implement, wherein mowing members are rotatably journalled above a housing accommodating a driving gear, stones may be jammed between the mowing members and the housing. Damage of the mowing implement through stones is avoided in that each mowing member mainly comprises two cutter supports adapted to turn upwardly with respect to the driving member each about a horizontal axis, which is located near the upright rotary axis of the associated driving member.
Claims16
A mowing implement comprising, in combination:
- an elongate housing adapted to be carried by a powered vehicle for movement over the ground surface with the housing extending transverse to the direction of movement effected by the powered vehicle;
- gear means disposed within said housing and including at least one drive gear disposed along the length of the housing, said drive gear having a vertical shaft connected thereto and projecting upwardly through said housing, said gear means imparting rotation to said shaft;
- horizontal pivot means attached to said shaft in closely overlying relation to said housing;
- a pair of cutter supports pivotally engaged by said pivot means, said cutter supports projecting radially from said shaft and each carrying a cutter member which sweeps a circular path which extends forwardly of said housing, and each cutter support being freely pivotal on said pivot means about a horizontal axis whereby each cutter support is free to deflect upwardly out of the plane of said circular path and away from the top of said housing during operation of the mowing implement.
