Abstract

A mower deck transport lock for a parallelogram lift linkage supporting a mower deck at any of a plurality of cutting heights where a striker plate contacts a height of cut selection knob. A transport bracket pivots into engagement with the striker plate only at a transport height above the plurality of cutting heights. A transport lock indicator is activated when the transport bracket pivots into engagement with the striker plate.

First claim

What is claimed is:

1. A mower deck transport lock, comprising:
a striker plate sliding into a height of cut selection bracket and supporting a mower deck at a plurality of different height of cut positions corresponding to the position of the striker plate;
a transport bracket riding on the striker plate in sliding engagement with a surface of the striker plate as the striker plate slides away from the height of cut selection bracket, the transport bracket pivoting automatically into locking engagement with the striker plate when the striker plate reaches a transport position above the plurality of different height of cut positions to hold the mower deck at the transport position; and
a transport lock indicator connected to the transport bracket and automatically extending out through a body panel as the transport bracket pivots into the locking engagement with the striker plate.

2. The mower deck transport lock of claim 1 further comprising a wire form connecting the transport bracket to the transport lock indicator.

3. The mower deck transport lock of claim 1 wherein the surface of the striker plate includes a planar face, further comprising a slot in the planar face of the striker plate through which the transport bracket passes to define the locking engagement when the striker plate is in the transport position.

4. The mower deck transport lock of claim 1 further comprising a pin insertable into any of a plurality of holes in the height of cut selection bracket for the plurality of different height of cut positions.

5. The mower deck transport lock of claim 1 wherein the transport lock indicator is manually moveable to disengage the transport bracket from the striker plate.

6. A mower deck transport lock, comprising:
a transport bracket movable into locking engagement with a striker plate to hold a mower deck at a transport position, wherein the transport bracket is slidable in engagement with a surface of the striker plate as the striker plate moves towards the transport position; and
a transport lock indicator adjacent an operator seat that is activated automatically without manual contact by raising the mower deck to the transport position, and deactivated by using a foot pedal to raise the mower deck and pushing in the transport lock indicator to move the transport bracket to disengage from locking engagement with the striker plate while remaining in sliding engagement with the striker plate.

7. The mower deck transport lock of claim 6 further comprising an electrical sensor that senses if the transport bracket is in locking engagement with the striker plate.

8. The mower deck transport lock of claim 6 further comprising an electrically activated transport lock indicator light.

9. A mower deck transport lock, comprising:
a parallelogram lift linkage supporting a mower deck at any of a plurality of cutting heights where a striker plate contacts a height of cut selection knob;
a transport bracket pivoting into locking engagement with the striker plate at a transport height above the plurality of cutting heights, wherein the transport bracket is slidable in engagement with a surface of the striker plate as the striker plate moves towards the transport position; and
a transport lock indicator activated automatically without manually contacting the transport lock indicator by pivoting the transport bracket into engagement with the striker plate.

10. The mower deck transport lock of claim 9 wherein the surface of the striker plate includes a planar face, wherein a projection on the transport bracket movable with the transport bracket enters a slot in the planar face of the striker plate as the transport bracket pivots into the locking engagement with the striker plate.

11. The mower deck transport lock of claim 9 wherein a sensor detects the transport bracket pivoting into engagement with the striker plate, and the sensor activates an electrically activated transport lock indicator.

12. The mower deck transport lock of claim 9 wherein the mower deck may be raised and the transport lock indicator may be depressed to disengage the transport bracket from the striker plate.

13. The mower deck transport lock of claim 6 wherein the surface of the striker plate includes a planar face, further comprising a slot in the planar surface of the striker plate through which the transport bracket passes to define the locking engagement.
