Abstract

A mower deck side discharge chute mounting includes a wire form hinge having a first leg, a second leg that is collinear with the first leg, and an intermediate mounting portion attached directly to a multi-blade mower deck between the first leg and the second leg. A side discharge chute pivots on the wire form hinge and can be installed or removed from the wire form hinge only if the chute is in a raised position relative to the mower deck.

First claim

The claimed invention is:

1. A mower deck side discharge chute mounting, comprising:
a wire form hinge having a first leg, a second leg that is collinear with the first leg, and an intermediate mounting portion attached directly to a multi-blade mower deck between the first leg and the second leg;
a side discharge chute pivoting on the wire form hinge on bearings that can slide on or off the first and the second legs of the wire form hinge only if the side discharge chute is in a raised position relative to the mower deck; and
a torsion spring biasing the side discharge chute toward a lowered position relative to the mower deck; a keyway in each of the bearings and a radial projection on each of the first and second legs of the wire form hinge that fits through the keyway.

2. The mower deck side discharge chute mounting of claim 1 wherein the torsion spring includes a coil around the first leg of the wire form hinge.

3. The mower deck side discharge chute mounting of claim 1 further comprising a second inner chute pivoting on the wire form hinge under the side discharge chute.

4. A mower deck side discharge chute mounting, comprising:
a wire form hinge mounted directly to a multi-blade mower deck and having a first leg and a second leg extending through bearings on a side discharge chute;
a torsion spring on the wire form hinge between the bearings and biasing the side discharge chute toward a lowered position; and
a radial projection on each of the first and the second legs that fits through a keyway on the bearings only if the side discharge chute is in a raised position.

5. The mower deck side discharge chute mounting of claim 4 wherein the first leg and the second leg are collinear.

6. The mower deck side discharge chute mounting of claim 4 further comprising an intermediate mounting portion between the first leg and the second leg.

7. The mower deck side discharge chute mounting of claim 4 wherein the raised position is about 90 degrees relative to a horizontal top surface of the multi-blade mower deck.

8. The mower deck side discharge chute mounting of claim 4 wherein the torsion spring comprises a first coil and a second coil, and the side discharge chute comprises a main chute independently biased toward the lowered position by the first coil, and a second chute independently biased toward the lowered position by the second coil.
