The Sled Assembly
The Sled (See FIG 1, Page 8) has been designed to be solid, strong, and heavy
in order to keep the sensor as close to the ground as possible at all times. The
Sensor’s lowest light beam is 20mm from the ground. To generate accurate
pasture cover readings, it is important that the sled remains in contact with the
ground. To ensure that this is maintained as much as possible, the frame on
which the sensor is mounted has been constructed from heavy gauge steel. This
provides both structural strength and the weight necessary to keep the sled on
the ground. Special “blade” like fixtures have been built into the “feet” of the
frame to stabilise tracking during operation.
The wheels are only used for transport purposes to and from work sites
and when travelling along farm tracks / races. When in the measurement
position, the wheels are locked up clear of the ground and the sled sits
down firmly on the ground. In this position, the wheels act as stabilising
outriggers minimising the effects of sideways rocking.
Please Note. The wheels should be placed in the transport position
whenever the Pasture Meter is not being operated on grass, however brief
the period is.
