The GreensPro steering system includes a number of
components that cause the front steering head (2) and
rear steering head (1) to rotate when the steering
wheel is turned by the operator. The rotation of the
steering heads allows the machine to change direction.
The amount the steering wheel can be turned is
limited, so the turning circle of the greens roller is
relatively large.
Steering system components include the steering
wheel and attached steering shaft, which is connected
to the steering pivot (7), steering pivot rod (6), steering
disc assembly (4), rear steering head linkage arm (3),
front steering head linkage arm (5), rear steering head
assembly (1), and front steering head assembly (2).
With the exception of the steering wheel and steering
shaft, steering system components are attached to the
bottom of the chassis shown in Figure 1.

When the steering wheel is turned by the operator, the
steering pivot (7) is rotated. Steering pivot movement
causes the steering disc assembly (4) to be rotated by
the steering pivot rod (6), which connects the steering
pivot (7) with the steering disc assembly (4). The
steering disc assembly (4) is connected to two steering
heads by the rear steering head linkage arm (3) and
the front steering head linkage arm (5). Rotation of the
steering disc assembly (4) causes rotation of the
steering heads, which allows the machine to change
direction while in motion.
