Abstract

A riding greensmower clean-up pass speed control system reduces the maximum ground speed if a clean-up pass control is actuated. The reduced maximum ground speed is adjustable using a display. The maximum ground speed is increased to the previous ground speed each time the plurality of grass cutting reels are raised after the clean-up pass.

First claim

The invention claimed is:

1. A riding greensmower clean-up pass speed control system, comprising:
a riding greensmower having a traction circuit propelling the riding greensmower at a variable ground speed up to a maximum ground speed while mowing, and having a lift/lower circuit to raise and lower a plurality of cutting units; and a mow circuit to rotate a cutting reel in each of the plurality of cutting units at a variable reel speed up to a maximum reel speed; and
a controller commanding the traction circuit to reduce the maximum ground speed to a maximum clean-up pass ground speed and the mow circuit to reduce the maximum reel speed to a maximum clean-up pass reel speed upon actuation of a clean-up pass control, and commanding the traction circuit to increase the maximum ground speed above the maximum clean-up pass ground speed and the mow circuit to increase the maximum reel speed above the maximum clean-up pass reel speed upon receiving a signal from the lift/lower circuit indicating the plurality of cutting units are raised.

2. The riding greensmower clean-up pass speed control system of claim 1 further comprising a display on the riding greensmower that is adjustable to change the maximum clean-up pass ground speed.

3. The riding greensmower clean-up pass speed control system of claim 1 wherein the maximum clean-up pass ground speed is for a pedal position of 100%.

4. A riding greensmower clean-up pass speed control system, comprising:
a riding greensmower having a clean-up pass speed control that reduces a maximum ground speed to a maximum clean-up pass ground speed and reduces a maximum reel speed to a maximum clean-up pass reel speed while mowing with a plurality of cutting reels;
a lift/lower switch that raises the plurality of cutting reels and increases the maximum clean-up pass ground speed to the maximum ground speed and increases the maximum clean-up pass reel speed to the maximum reel speed.

5. The riding greensmower clean-up pass speed control system of claim 4 wherein the maximum ground speed and the maximum clean-up pass ground speed are each for a pedal position of 100%.

6. The riding greensmower clean-up pass speed control system of claim 4 further comprising an adjustable display for setting the maximum clean-up pass ground speed and the maximum clean-up pass reel speed.

7. The riding greensmower clean-up pass speed control system of claim 4 wherein the clean-up pass control reduces the maximum ground speed to a maximum clean-up pass ground speed only when a PTO switch is actuated to rotate the cutting reels.

8. A riding greensmower clean-up pass speed control system, comprising:
a plurality of grass cutting reels on a riding greensmower with a traction drive circuit that propels the riding greensmower while mowing at up to a maximum ground speed, and propels the riding greensmower while mowing at up to a reduced maximum ground speed if a clean-up pass control is actuated on a display; the reduced maximum ground speed being adjustable using the display;
the traction drive circuit increasing the maximum ground speed from the reduced maximum ground speed each time the plurality of grass cutting reels are raised; and
a mowing circuit changing a maximum rotational speed of the plurality of grass cutting reels from a reduced maximum cutting reel speed to a maximum cutting reel speed each time the plurality of grass cutting reels are raised.

9. The riding greensmower clean-up pass speed control system of claim 8 wherein the maximum ground speed and the reduced maximum ground speed are each for pedal position of 100%.
