The new ECO-TWIN PTO<br />
The ECO-TWIN PTO was designed with the vision that the<br />
engines of current tractors can supply the same power<br />
even with a lower rpm.<br />
Virtually all tractors have the ability to switch off the rear Pto<br />
between 1000 revolutions and what is known as a ‘low-power<br />
mode’. In that case, 1000 revolutions of the rear power take-off<br />
shaft is achieved with a reduced engine rpm of approximately<br />
1600 rpm. With Eco-tWIN Pto, this is now also possible in<br />
the front Pto. the Eco-tWIN Pto has been designed for<br />
tractor classes of 100-250 hp.<br />
Two clutches<br />
the mechanics in the Pto are based on the tried<br />
and tested <strong>Zuidberg</strong> technique with a wet lamella<br />
clutch and an separate hydraulic circuit. However,<br />
two clutches are incorporated in this housing. the<br />
first clutch works as it does in any other <strong>Zuidberg</strong><br />
housing, by connecting the outgoing axle directly to<br />
the lowest gear from the housing; the so-called drive<br />
cup. the second clutch connects the outgoing axle<br />
with the drive cup via a planetary gear system. the<br />
planetary gear system provides the extra deceleration<br />
between the gear and axle. Due to its compact design,<br />
the housing uses only 32 mm more space than, for<br />
example, a standard PN housing and uses 54 mm more<br />
space than a PA3/4, which is mounted on these tractors in<br />
the current <strong>Zuidberg</strong> range.<br />
In its programme, <strong>Zuidberg</strong> already has a gearbox with<br />
adapted transmission ratio, with which a lower<br />
engine rpm can be realised. If you would also<br />
like to use the normal 1:2 ratio, the gearbox<br />
must be changed. that is now a thing of the<br />
past with the Eco-tWIN Pto.<br />
Use<br />
As regards use, imagine duties where the required<br />
power of the front and rear Pto allow it to operate<br />
with lower revolutions. for example, when mowing.<br />
Another use is when the front machine needs to<br />
operate at 1000 revolutions and the rear machine<br />
can operate with fewer revolutions. the user can set<br />
the front Pto electronically to 1000E from the<br />

<strong>Zuidberg</strong> is supplying two Pto’s with different transmission ratios, combined in a<br />
single unit. Hence the decision to name it the Eco-tWIN Pto.<br />
cabin, whilst the rear uses the 1000E setting<br />
also. Here you should imagine, for example, a<br />
combination of front-mounted mower and forage<br />
and discharge wagon (silage), a foliage harvester<br />
combined with a potato harvester or a hydro pump in<br />
the front Pto and another arbitrary machine behind<br />
the tractor.<br />
