4.13- Speed of the drums
The working speed of the drums is determined
by the combination of the gears used in the
transmission.
At the top of each drum there is a gearbox
through which, by changing a pair of gears,
you can change the speed of the drums.
The rotation synchronism between the drums
and the feeding drums generates an ideal
crop processing flow, guaranteeing the cut
quality and avoiding overload problems that
can, for example, cause the safety pins to
break.
In general:
Higher drum speed is used for crops with little
volume and lower speed for more bulky crops.
