Filed:

Oct 5, 1989

Appl. No.:

7/417506

Inventors:

Joseph E. Berrios - Coral Springs FL

International Classification:

A01D 3512

US Classification:

56 109

Abstract:

The present walk-behind, self-propelled motor has two hydraulic motors whose rotors are directly connected to the hubs of respective drive wheels on opposite sides of the mower deck toward the rear. These motors are driven by respective pumps, each of which has its direction and rate of fluid displacement controlled by a handle mechanism on the upper end of a corresponding fixed handle extending up from the deck at the rear. Each handle mechanism has a pivoted handle coating with a locking lever to set the corresponding pump in neutral, forward or reverse. An internal combustion engine drives both pumps as well as cutting blades located below the mower deck toward the front. Vertically pivoted wheels are located in front of the mower deck.

Abstract:

An improvement in a walk-behind, self-propelled lawn mower including a mower deck having an upper deck surface, a deck rear end and deck rear edge, several mower wheels, a mower engine, a pair of handle bars extending upward from the mower deck at the rear of the mower deck and steering controls includes a plate member for supporting a mower operator during mower use, a hinge pivotally connecting the plate member to the rear end of the mower deck, plate member abutment structure for stopping the plate member from pivoting to a position substantially below the plane of the mower deck. The hinge preferably includes a first hinge pin receiving element secured to the upper surface of the deck and spaced apart from the rear edge of the mower deck, and a second hinge pin receiving element secured to the plate member, and where the plate member abutment structure includes a portion of the mower deck between the first hinge pin receiving element and the rear edge. The abutment structure preferably includes a bracket element secured to the mower deck and extending rearwardly from the mower deck, the bracket element having an upper surface substantially coplanar with the upper surface of the mower deck for supporting the plate member when pivoted to a down position. A seat structure is optionally provided for the operator to sit upon, the seat being secured to and extending upward from the plate member.
