Abstract

A walk-behind mower includes a frame and a power source attached to the frame. A selectively steerable drive wheel and a set of follower wheels are rotatably attached to the frame. The walk-behind mower includes a steering wheel assembly attached to the frame, the assembly including a steering column and a steering wheel attached to the steering column. The walk-behind mower also includes a universal joint connecting the steering wheel assembly to the frame. The walk-behind mower further includes a mower deck attached to the frame and a mower blade assembly attached to the deck. In other examples, the walk-behind mower includes a front section and a rear section that rotate relative to each other about a vertical axis.

First claim

The invention claimed is:

1. A walk-behind mower, said walk-behind mower comprising:
a frame;
a power source attached to said frame;
a selectively steerable drive wheel rotatably attached to said frame;
a set of follower wheels attached to said frame;
a steering wheel assembly attached to said frame, said steering wheel assembly comprising:
a steering column;
a steering wheel attached to said steering column;

a universal joint connecting said steering wheel assembly to said frame;
a mower deck attached to said frame; and
a mower blade assembly attached to said deck,
wherein said steering wheel assembly applies a force to said frame on a vertical axis passing through said selectively steerable drive wheel,
wherein said vertical axis is co-linear with a vertical centerline of said steerable drive wheel.

2. The walk-behind mower according to claim 1 , further comprising:
a front section, wherein said front section comprises:
said mower deck;
said selectively steerable drive wheel;

a rear section, wherein said rear section comprises:
said frame; and
said set of follower wheels.

3. The walk-behind mower according to claim 2 , wherein said front section and said rear section are rotatably connected to each other.

4. The walk-behind mower according to claim 3 , wherein one of said front section and said rear section is configured to rotate relative to the other of said front section and said rear section about a vertical axis.

5. The walk-behind mower according to claim 4 , wherein one of said front section and said rear section is configured to rotate relative to the other of said front section and said rear section about a centerline of said selectively steerable drive wheel.

6. A walk-behind mower, said walk-behind mower comprising:
a frame;
a power source attached to said frame;
a selectively steerable drive wheel rotatably attached to said frame;
a set of follower wheels attached to said frame;
a steering wheel assembly attached to said frame, said steering wheel assembly comprising:
a steering column;
a steering wheel attached to said steering column;

a universal joint connecting said steering wheel assembly to said frame;
a mower deck attached to said frame;
a mower blade assembly attached to said deck,
a front section, wherein said front section comprises:
said mower deck;
said selectively steerable drive wheel;

a rear section, wherein said rear section comprises:
said frame; and
said set of follower wheels,

wherein said front section and said rear section are rotatably connected to each other,
wherein one of said front section and said rear section is configured to rotate relative to the other of said front section and said rear section about a vertical axis,
wherein one of said front section and said rear section is configured to rotate relative to the other of said front section and said rear section about a centerline of said selectively steerable drive wheel.
