Working Depth Adjustment; Rotors Speed Variation - Alpego DJ serie Betriebs- Und Wartungsanleitung

MANUALE ERPICI PIEGHEVOLI DJ-DP-DK-DMAX
ONLY FOR DmaX-800
While the implement is working, the hydraulic lifting mechanism of the tractor must
always be in its floating position (see sticker at the side).
Thus a vertical motion of the machine independently from the tractor is
possible.
During transport always engage the blocking sytem of the lifting device
Example of disengagement from the tractor (New Holland)
The real roller of the power harrow and the lower links of its 3-point hitch, which are also built so as to allow a certain flexibility,
so that the machine adjusts to the shape of the ground, guarantee a constant working depth and good levelling of the soil.
When changing directions or driving in reverse gear always keep the implement off the ground.

5.1. WORKING DEPTH ADJUSTMENT

The depth working adjustment P of the machine is determinate by the position of the levelling roller in
relation to the lower edge of the blades.
The greater the difference P between the blades and the lower part of the levelling roller, the greater the
working depth.
Practically, the increase of the working depth is obtained by shifting the proper pins A to a higher hole.
In order to reduce the depth, shift the pins A toward the bottom.
We suggest to starting always with one minimum working depth and then to increase it progressively until
the required working depth is reached.
Make sure that all the pins A are in the same position during the work. It is advisable a working depth of 80÷150 mm.

5.2. ROTORS SPEED VARIATION

In order to obtain the best possible crumbling of the soil, the following two factors must be taken into consideration:
- The speed pf the tractor
- The rotation speed of blade-holder rotor
The gear box allows the machine to work the soil with different rotor speeds, by using different gear
couples available on request and interchangeable with those supplied standard. (see table 5.3 and 5.4)
The greater the number of the rotor revolutions, the greater the crumbling degree of the soil but also
higher is the power absorbed by the tractor and the wear of the blades.
Therefore, it is advisable to use the lowest possible speeds but which can give as a result a good
working of the soil.
In order to invert or substitute the gear couple of the gear box, remove the lid C (making sure not to
break the gasket), remove the springs D and the gears A and B and invert their position or replace
them with new ones; then replace the springs D and the lid C by lightening the M10 screw E at not no
more than 4 Kgm.
The tables show the labels on the change of gear of the machine, the standard gear pair is that shown in the table, the others are
available upon request.
