5.6. USE OF THE REAR BAR

The rear bar have the double function of:
- regulating the crumbling degree of the soil, the number of revolutions of the rotor and
the driving speed remaining constant;
- horizontally levelling the soil.
A greater refining is achievable lowering the bar; a lesser one instead, lifting it; the regulation has
to be made through the regulator
Being ROTODENT provided with two rollers and consequently with two refining bars, regulate the
equipment so that the two bars could work at the same depth.
Adjustment of the bar A
Always begin working with the bar A completely lifted, position the machine, so as to reach the desired working depth. Gradually
lower the bar A using the regulators B until the soil before the roller becomes flattened. This is normally the ideal working position,
even in soil clattered with grass or residual substances. If the soil is ploughed or free of residues, the bar can be lowered by a few
strokes, in order to obtain aqn even finer degree of crumbling. Shoulds this not be enoughyet, it will be necessary either to
increase the number of revolutions of the rotor or to decrease the driving speed of tractor.
There is a limit beyond which the bar cannot be lowered, otherwise there will be a higher absorption of power, without an
improvement in the work performance. This will be noticed even from the driver's seat by observing the large quantity of soil
being pushed forward by the rotor. Besides, the worked soil will not be well levelled. You will have to lift the bar according to.
IMPORTANT: The ALPEGO levelling bar is automatically self-adjusting. If the working depth of the equipment is changed, a
parallelogram will keep the bar itself in the correct position.
WORKING IN WET SOILS: under these conditions no fine crumbling of the soil is usually required. Therefore, it might be useful
to work with the bar lifted and so also to reduce the number of revolutions of the rotors. This will certainly save the tractor energy.
WORKING IN ROCKY SOILS: We suggest that, when working in this type of soils, the bar should be lifted or, even better,
removed it altogether by loosing the two lateral bolts and the cranks.
