Abstract

A mulch kit control lever with a detent plate attached to the top surface of a mower deck, and a vertically oriented pivot pin extending through the detent plate and through the mower deck and engaging a mulch gate. A pivoting handle connected to the pivot pin moves the mulch gate between a side discharge position and a mulching position. A detent pin on the handle abuts a first stop on the detent plate in the side discharge position and a second stop on the detent plate in the mulching position.

First claim

The invention claimed is:

1. A mulch kit control lever, comprising:
a detent plate attached to a top surface of a mower deck, the detent plate having a first stop and a second stop;
a vertically oriented pivot pin extending through the detent plate and through the mower deck and engaging a mulch gate;
a handle having a first end and a second end and an intermediate portion engaging the pivot pin and pivoting to move the mulch gate between a side discharge position and a mulching position;
a detent pin on the first end of the handle abutting the first stop on the detent plate in the side discharge position and the second stop on the detent plate in the mulching position; and
a coil spring around the pivot pin biasing the detent pin down against one of the first stop and the second stop of the detent plate, the coil spring compressible by pushing down the second end of the handle to move the detent pin off the detent plate.

2. The mulch kit control lever of claim 1 wherein a portion of the pivot pin has a square cross section engaging a square hole in the handle.

3. The mulch kit control lever of claim 1 wherein the handle is stepped.

4. The mulch kit control lever of claim 1 wherein the detent pin is adjustably located in a slot in a first end of the handle.

5. A mulch kit control lever, comprising:
a handle connected by a vertically oriented pivot pin to a pivoting mulch gate;
a detent pin on the handle abutting a first stop on a detent plate when the mulch gate is in a side discharge position and abutting a second stop on a detent plate when the mulch gate is in a mulching position; and
a coil spring around the vertically oriented pin and biasing the detent pin downwardly against the detent plate; the coil spring compressible by pushing down the handle to lift the detent pin above the detent plate.

6. The mulch kit control lever of claim 5 wherein the vertically oriented pivot pin extends through a hole in the detent plate.

7. The mulch kit control lever of claim 5 further comprising a vertical hinge connecting the mulch gate to a deflector plate.

8. The mulch kit control lever of claim 7 wherein the vertically oriented pivot pin extends through the vertical hinge.

9. A mulch kit control lever, comprising:
a mulch gate pivoting between a side discharge position and a mulching position;
a pivoting handle mounted on a detent plate and having a detent abutting a first stop on the detent plate in the side discharge position and a second stop on the detent plate in the mulching position;
a pivot pin extending through the detent plate and connecting the mulch gate to the pivoting handle; and
a coil spring around the pivot pin biasing the detent down against one of the first stop and the second stop of the detent plate, the coil spring compressible by pushing down the pivoting handle to raise the detent off the detent plate.

10. A mulch kit control lever of claim 9 wherein the pivot pin is in a hinge between the mulch gate and a deflector plate.
