INTRODUCTORY INFORMATION
1.4 MACHINE DESCRIPTION
The belt hay tedder in the “G” series is a machine
for the preparation and harvesting of forage.
It consists of a load-bearing frame made of welded
steel sections and a double belt on which some
spring supports are fixed to drag the forage.
It has two wheels with two levers to keep the
machine level during operations.
This series of machines may be used with several
different types of tractor with a three-point hydraulic
lift.
It is attached to the tractor by means of the three-
point connection which firmly holds the two
machines together and makes work safe.
Movement is transmitted by the power take-off, via
apropeller shaft to the rake drive unit and then to
the belt.
The belt rotates at a distance of approximately 1-2
cm above ground level and enables forage to be
raked, turned, loosened and aired.
