b) If necessary, raise or lower the header through the support
foot(Hydraulicjack)(3).
c) Install the hitch pin (4) and lock it with a cotter pin, preventing
accidentalrelease.
d) Pull the lock pin (5) and place the foot support (3) horizontal.
Then,installthelockingpinagain.

The angle of 0º is the centerline of the tractor. The maximum angle allowed for PTO when it is being
drivenbytheTDP,is15º.Ifyouexceedthisvalue(example:maneuvers),unplugthepower.
Note:
With the TDP “off”, the maximum angle of the cardan maneuvers can reach a
maximumof30º.
The figure illustrates the maximum allowable tilt angle of the driveshaft with the car in motion and

Attention:
Maneuvers with TDP connected in a greather than 15º angle can cause serious
accidents.

Operating Adjustments

Connecting the hydraulic hoses
a) On the remote control tractor, use two outputs hydraulic: one
for opening and closing the discharge port and the other for
activatingtheunloadingbelt.
The photo with the levers (2) may vary according to
the mark and tractor size, and thus follow the
operatinginstructions.
b)Removetheprotectivecaps(1)remotecontrolandhoses.
c) Connect the terminals of these hoses pushing firmly against
theremoteterminals.
d) Bleed the circuit: to remove the air from the hoses and
cylinders, turn the levers of the remote control several times in
bothdirectionsuntiltheendofthecourse.

PTO Speed
Guidance on the Discharge Flow
18 Operation Technical Manual
During operation, rotation of power should never exceed 540 RPM in
ordertopreventthespillageofthemixture.
So you have to figure out which engine speed in decision 540 RPM that
providespower.
Forthisthesearefourpossibilities:
-Checkforapossibleindicationthetachometer(revcounter)ofthetractor.
-Checkthatthetractorhasadecalthatinformation.
-Consultthemanualofthetractor.
-Ofdoubtpersists,useatachometerdirectlyontheshaftpowertake-off.
Therearebasicallytwowaystocontroltheflowofthedischargeofthemixer:
1- Varying the rotation of the TDP(not more than 540 rpm), which controls the rotor speed mixer VMN
4.0.
2-Varyingthetravelspeedofthetractor.
3-Regulatingvalveinstalledatthebeginningofthehose.
If for example, the rotor speed of the mixer VMN 4.0 is too high relative to the mat, there could be
accumulation of material at the exit door, as well as non-uniform distribution. In the case, you should
slowthetreadmill,followingtheinstructionsoftheabove.
Ifthe beltspeed is too low comparedto therotor mixer VMN 4.0, lackingin materialoutput port. In this
case,increasetherotationoftheTDP(notmorethan540rpm).
Thetractorspeedshouldbecompatiblewiththedischargeflow.Todepositmoremixinginthetroughs,

Make sure your tractor has a table
and/or graphic scale, informing the
travelspeed fordifferentspeedineach
