Tilling width adjustment
The adjustable tiller model allows you to set working
widths of 40, 50, 60 cm, to suit the type of crop.
Adjustment of tilling width is obtained by reversing
the position of the two pairs of outside tiller rotors of
each tilling element, and by removing or adding one
tiller rotor at the end of the two tillers.
Refer to figure 2 to determine the tiller rotor configura-
tion required to obtain the desired tilling width, then
proceed as follows:
To reverse the position of the outside tiller rotor pairs
(fig. 3, item 1), remove the four attachment nuts (2)
and invert the position of the outside pair of tiller ro-
tors, fitting the left rotor to the right and vice-versa.
Make sure you keep the cutting edge of the rotors
facing the front of the machine.
Adjustment of protection guards
a.
Adjust width of protection guards to suit new tilling
width. To do this, remove the screws (fig. 4, item
1), and install the two side extensions (2).
b.
Adjust width of matching piece (3) by use of
screws (4).
Tilling depth adjustment
To vary tilling depth you must adjust the height of the
tine (fig. 5, item 1). Proceed as follows:
a.
Remove nut and bolt (2).
b.
Move the tine up or down until the slot on the
bracket corresponds to the desired hole on the tine
shank. Replace nut and bolt (2) and fully tighten.
Ground adjustment
Adjust the position of the rotary tiller as follows to en-
sure correct movement over different types of ground:
HARD GROUND
If the tiller tends to jump on hard ground, lower the
tine to lift the rotary tiller.
SOFT GROUND
If the tiller tends to sink in on soft ground, lower the tine
to move the center of gravity over the machine wheels.
ROTARY TILLER MAINTENANCE
After the first 50 hours (running in)
a.
Check that all nuts and bolts are secure. Tighten if
necessary.
b.
Change the oil in the tiller drive unit as follows.
Remove plug (fig. 6, item 1) and turn the attach-
ment upside down to drain out the exhausted oil.
Return the attachment to the upright position, and
add 0.3 l of the same oil used for the gearbox.
