DANGER
Whenever the two hoeing units are positioned vertically, make sure that they are automatically locked in place with the
two locking hooks
4.6.1 WORK DEPTH ADJUSTMENT
The work depth of the folding steerage hoe can be regulated, depending on the version:
with hydraulically controlled cylinders ( 20 Fig. 1 ).
Raise the roller to dig deeper into the soil. Lower the roller if the work depth must be more shallow. Work depth adjustment with
the hydraulically controlled cylinders is carried out from the driving position by means of a hydraulic actuator that controls the two
hydraulic cylinders (
20 Fig. 1 ). These cylinders regulate the rear rollers ( 19 Fig. 1 ) and therefore determine the work depth. Both
hydraulic cylinders have a balancing valve that allows the rollers and, thus, the work depth to be regulated to the same extent.
4.6.2 HITCHING/UNHITCHING THE HOEING UNITS
The hydraulic circuit of the machine allows the two hoeing units to be hitched and unhitched in an automatically sequential way by
means of a control in the tractor, by moving the two hooks used for road transport. After each command, always check to make
sure that the system has coupled or released correctly.
4.7 DURING WORK
Proceed in the following way after you have correctly hitched the machine, sat down in the driver’s seat of the tractor and started
the tractor engine:
Raise the machine about 10 cm from the ground so that the rotor does not touch the vegetation that needs to be cut
Run the engine at a low rate and engage the PTO
Gradually accelerate until the PTO is operating at full rate
Engage the forward gear and start work with the PTO at full rate
Gradually lower the machine until it rests on the ground. This allows it to adapt to the contours of the soil.
CAUTION
Do not depress the accelerator pedal in an imprudent way with the PTO engaged.
To break up the soil to the required degree, you must consider several factors, ex:
The nature of the soil (medium consistency, sandy, clayey etc.)
The working depth
The ground speed of the tractor
Optimum machine adjustment
For a better soil levelling and crumbling, the rotary tiller is equipped with a rear hood, with adjustable opening by means of a
locking chain and on request by means of a spring rod.
WARNING
Adjust the hook by keeping it as opened as possible to obtain a better levelling thus avoiding dangerous throwing of the
clods and stones as well as the hood itself
CAUTION
A better soil crumbling can be obtained with a low tractor ground speed, the rear bar lowered and the blade-holder rotor spinning at
200 rpm. Besides holding back the clods already broken up by the blades, the rear bar also gives a well-levelled and uniform surface
