5.6.1
Gearbox/tractor PTO shaft speed/tine speed
Different soils require that the tine speed be adjusted in order to attain
the desired fine seedbed. The implement gearbox makes this
adjustment possible.
Never select a higher tine speed than is absolutely necessary. If the
tine speed is increased, the power requirement and tine wear
increase disproportionately.
Selecting the right tine speed lowers wear costs and increases area
efficiency.
Always set the tractor PTO shaft speed to 1000 rpm. Lower tractor
PTO shaft speeds lead to higher torques at the universal joint shaft
and can cause rapid wear of the overload clutch.
5.7 Two-gear
gearbox
The tine speed can be adjusted by
switching the gears with the gear lever (Fig.
32/1) in the two-gear gearbox
switching the gear wheels in the two-gear
gearbox
The table (below) shows the tine speeds and
gear wheel pairings and gear lever positions.
