INTRODUCTION
Important
Read, understand and obey the safety rules and operating
instructions in the Agrilift 737 - 1037 Operator's Handbook
before attempting any maintenance or repair procedure.
This manual provides the machine owner and user with
detailed information on the scheduled maintenance. It
also provided qualified service technicians with
infromation on troubleshooting and repair procedures.
Basic mechanical, hydraulic and electrical skills are
required to perform most procedures. However, several
procedures require specialized skills, as well as specific
tools and equipment.
In these instances, we strongly recommend letting service
and repair the machine at an authorized TEREXLIFT
service center.

Technical Publications
No part of this publication may be reproduced, stored in
a retrieval system or transmitted in any form or by any
means without prior written permission from TEREXLIFT
srl.
In pursuing a policy of constant quality improvement,
TEREXLIFT srl reserves the right to make changes at
any time and without undertaking to give prior notice;
therefore, also this publication may be subject to
modifications.
The source of mechanical energy of this machine is a
Deutz turbo-compressed diesel engine (pos. 1), model
BF4M2012, with a max torque of 390 Nm at 1500 rev/
min. and a power rating of 74.9 kW at 2300 rev/min.
The VDT12000 "power shift" mechanical transmission
(pos. 2) produced by Dana is fitted to the flywheel side
of the engine, and connected to this engine by a
Technodrive coupler with elastic joint and with a 1-to-1
ratio. This transmission has 4 "forward" speed ratios
and 3 "reverse" speed ratios.
The torque transmission between engine and drive is
controlled by a Dana hydrodynamic torque converter.
On the special power takeoff (PTO) lodged in the
transmission housing (pos. 2) there is a Casappa openloop gear pump (with fixed displacement) (pos. 3) with
priority valve integrated in the housing. The
displacement of this pump is 43 cm3. Its function is to
provide hydraulic power, under form of pressure and
capacity, to the steering cylinder of the machine (priority
side) and to the telescopic boom cylinder (secondary
side).
The diesel engine to pump revs ratio is 0.971:1, thus
the pump turns just a bit faster than the engine.
A second Casappa open-loop gear pump (with fixed
displacement) (pos. 4) with a displacement of 25 cm3,
is installed on the power takeoff (PTO) of the engine, on
the distribution side. This pump feeds the servo-assisted
braking system (pos. 28), the (optional) distributor (pos.
22) operating the frame levelling and the rear (optional)
hydraulic sockets, and the oil-dynamic circuit of the
(optional) three-point hitch (pos. 26).
The suction lines of the open-loop pumps (pos. 3) and
(pos. 4) are protected by an immersed filter (pos. 5),
placed inside the 85-lt. hydraulic fluid tank (pos. 6).
The mechanical torque at the VDT12000 transmission
output (pos. 2) is transmitted to the front axle (pos. 30)
and the rear axle (pos. 29), both model 212
manufactured by Dana, through Cardan shafts.
The hydraulic drive (pos. 7) of the “load sensing” type
with a displacement of 315 cm3, receives oil from the
priority line of the pump (pos. 3) in relation to the “load
sensing” signal sent by the hydraulic drive and
connected to such pump with function of pilot signal.
In this way, the input flow to the hydraulic drive will be
exactly the one needed for the instantaneous steering
functions; any excess flow of the pump will be used for
the operation of the telescopic boom.
The steering circuit is protected against input
overpressures by a pressure reducing valve set at 140
bar. On the two delivery lines, there are other two
reducing valves with anti-shock function set at 200 bar.
The function of these two valves is limiting possible
shocks on the steering wheel in case of overstress on
the steering cylinders.

The three pressure reducing valves are installed in the
hydraulic drive (pos. 7) and cannot be regulated from
the outside.
The steering circuit is completed by the front steering
cylinder (pos. 9), the rear steering cylinder (pos. 10)
[these cylinders being integral part of the front axle (pos.
30) and the rear axle (pos. 29) respectively] and by a 4-
way/3-position solenoid valve (pos. 8) for the selection
of the three different steer modes (rear wheels straight,
co-ordinate front/rear steering and independent front/
rear steering). When the solenoid valve (pos. 8) is not
energised, the front steering cylinder is fed by the
hydraulic drive and the rear cylinder is blocked. When
one magnet or the other of the solenoid valve (pos. 8)
is energised, the chambers of the cylinders are
connected in a different manner thus causing the desired
steering effect.
The Bucher/Tecnord electro-proportional modular
distributor (pos. 11), with 5 sections, receives oil from
the secondary line of the pump (pos. 3) and feeds all of
the movements of the telescopic boom, as well as the
rear (optional) power takeoff. This distributor consists
of an input head with a 3-way pressure compensator
used as a flow regulator for the user which works at
max load (load sensing), and as a discharge valve when
the pump flow is not used for the boom movements,
and of 5 modules, each of them controlling a specific
movement of the telescopic boom (4 in total, that is
lifting/lowering, attachment holding plate rotation, boom
extension/retraction, attachment locking/unlocking) and
the rear (optional) power takeoff.
In the head there is a pressure relief valve set at 270 bar
which, acting on the line of the “load sensing” signal,
limits the maximum pressure at the inlet of the distributor
through such 3-way compensator. On the main inlet
head of the distributor, there is the pilot line head which
includes an inlet safety filter, a pressure relief valve acting
on the pilots line, and a safety solenoid valve which,
when de-excited, discharges the input pilot pressure,
thus preventing the distributor from working. This
solenoid valve is used as a “dead man” control and is
activated by the relevant button on the joystick in the
driving cab. The pilot head delivers oil at pressure to
the 5 pilot modules of the distributor which are used to
operate the relevant main sliders in relation to the
command signal they receive from the joystick via the
control unit.
Module 1 of the distributor controls the telescopic boom
lifting cylinder (pos. 13). This cylinder has one singleacting compensation valve with safety function. The pilot
module of this element of the distributor is the electroproportional type with electrical feed-back and
integrated electronics. The 0.35-lt. accumulator prefilled
at 50 bar (pos. 14) and located on the line of the
differential chamber of the lifting cylinder (pos. 13),
allows damping the boom swings when the same boom

is moved down.
Module 2 of the distributor controls the cylinder
operating the attachment holding plate of the telescopic
boom (pos. 15). This cylinder is equipped with a double-
acting compensation valve with safety function.
Paralleled to this cylinder there is the fork levelling (or
balancing) cylinder (pos. 16) equipped with a special
double-acting compensation valve. Inside this valve, the
one-way valves are installed in a reverse manner with
respect to the normal position to avoid the
pressurisation of the cylinder when the rotation
command of the attachment holding plate is operated.
Again inside this valve, there are other two one-way
valves set at 5 bar with anti-cavitation function. These
are used to deliver oil, sucked from the low pressure
line coming from the pressure relief valve (pos. 12), to
the fork levelling compensation circuit, when such circuit
cannot do it alone.
The pilot module of element 2 of the distributor is the
electro-proportional type with electrical feed-back and
integrated electronics. On the two control lines of the
cylinder (pos. 15), and integral to module 2, there are
two pressure relief valves set at 290 bar which protect
the automatic levelling system of the forks when the
boom is moved up and down and in case of overload
on the attachment holding plate (ex. use of the bucket).
Module 3 of the distributor controls the extension
cylinder of the telescopic boom (pos. 17). This cylinder
is equipped with a double-acting compensation valve
with safety function. The pilot module of this element
of the distributor is the electro-proportional type with
electrical feed-back and integrated electronics.
On the control line of the circular chamber of the cylinder
(pos. 17) and integral to module 3, there is a pressure
relief valve set at 150 bar which limits the load when
the boom is extended in those working zones where
the electronic overload warning system cannot detect
overload conditions with respect to the load chart of
the machine.
Module 4 of the distributor controls the attachment
locking cylinder (pos. 18). This cylinder has a double
one-way valve with hydraulic release and safety
function. The control module of this element of the
distributor is the ON/OFF electrical type with integrated
electronics.
On the feeding lines of this cylinder, there are two quickfit connectors (pos. 19) for the connection of the
hydraulic lines to the optional attachments which need
hydraulic power for their operation (ex. hydraulic winch
and maintenance jib, mixing bucket, etc.).
Module 5 of the distributor controls the rear (optional)
power takeoff (PTO) of the machine. This device is driven
by a Casappa oil-dynamic gear motor (pos. 20) for
open loop circuits of the reversible type with a
displacement of 38 cm3. The motor is flanged to a

mechanical reduction gear (pos. 21) with an output
shaft conform to the agricultural regulations for the
operation of different implements. A speed sensor
senses the rotation speed of the PTO and sends a signal
to the electronic control unit of the distributor (pos. 11)
which keeps such speed constant regardless of the loads
absorbed by the implement operated by the PTO.
Inside module 5 of the distributor, there are two anticavitation valves which are necessary for the operation
of the oil-dynamic motors.
The pilot module of the 5th element of the distributor is
of the electro-proportional type with electrical feed-back
and integrated electronics.
The pressure relief valve (pos. 12) set at 25 bar is located
upstream of the pressure port of the distributor (pos.
11). This valve supplies oil at low pressure (25 bar) to
the anti-cavitation circuits of the automatic levelling
system of the forks and to feed the pilot valves line of
the same distributor (pos. 11).
The SAFIM S6 servo-assisted braking system with pedal
(pos. 28) receives oil from the pump (pos. 4) and uses
this oil to pressurise 2 hydraulic accumulators
connected to this system. The oil at pressure contained
in these accumulator is then used to operate the service
brakes located inside the two axles (pos. 29) and (pos.
30).
The fill valve inside the braking system receives the flow
from the feeding line until the pressure in the line of the
accumulators reaches the calibration value of the cutout
valve set at 150 bar. When this pressure is reached, the
valve gradually releases all the flow to line B for other
uses.
The brake pedal located in the driving cab, which is an
integral part of the S6 braking system, is connected to
two proportional sliders which control the two separated
lines of the service brake, one for each axle. In relation
to the stroke of these sliders, a gradual communication
between the feeding line, connected to two
accumulators which, at their turn, are connected to ports
R1 and R2 (the accumulators have a 0.5-lt. capacity
and a fill pressure of 50bar), and the service brake lines
is established so the flow is distributed to such lines
and the discharge line increasing, in this way, the
pressure (and as a result the braking force) on the lines
of the service brakes. When the sliders are in the rest
position, the lines of the service brakes are connected
to the discharge.
The pressure switch set at 2-10 bar and connected in
parallel to one of the two lines of the service brake, sends
an electrical signal when the service brake is activated.
The pressure switch set at 70 bar and connected to port
F sends an electrical signal when the pressure inside
the feeding circuit of the brake lines is not enough to
guarantee the minimum breaking capacity.

The Bucher electro-hydraulic modular distributor of the
ON/OFF type for open loops (pos. 22) (on request)
controls the frame levelling and supplies oil at pressure
to the two additional rear oil-dynamic sockets equipped
with quick-fit hydraulic connections (pos. 23) and (pos.
24). It receives oil from port B of the braking system
(pos. 28) and uses this to operate the cylinder controlling
the frame levelling (pos. 25), equipped with doubleacting compensation valve which also acts as a safety
valve, as well as the additional rear hydraulic sockets
configured with quick-fit connections (pos. 23) and (pos.
24).
On the inlet head of this distributor there is a pressure
relief valve set at 220 bar.
The oil flow which is not used by the distributor to
operate the outriggers and the frame levelling function,
is sent to the (optional) three-point hitch (pos. 26) for
the operation of the lifting arms and the controlled effort
device. Finally, the excess oil which is not used by the
hitch is sent back to the tank (pos. 6).
The heat exchanger (pos. 27) is divided into three
sectors; one absorbs heat from the cooling circuit of
the diesel engine, the second cools down the hydraulic
circuit of the torque converter of the power shift
transmission and the third one cools down the hydraulic
circuit of the machine. The flow of the pump (pos. 3) is
conveyed to this third sector. The oil cooled down by
the heat exchanger is sent back to the tank (pos. 6).

2.18 ADVICE TO RENEW FLEXIBLE HOSES
Before disconnecting a hydraulic pipe, place
containers of suitable size underneath to prevent oil
spillage.
Plug all disconnected parts to prevent dust or
impurities from entering the circuit. They can cause
serious damage.
Before disconnecting the hydraulic pipe, check that
there is no residual pressure. In case, eliminate the
pressure operating the control levers with the engine
stopped.
In any case, disconnect the hydraulic pipe with
extreme caution and always wear suitable personal
protection equipment -e.g. goggles, gloves, facial
screen, etc.
Wrap up the end of the pipe to be disconnected with
some rags and slowly loosen the pipe connector so
that air comes out as slow as possible.
1Before disconnecting or refitting a flexible hose,
carefully clean the area all around.
2Blow some compressed air to remove any impurity.
3For an easier renewal of the hoses, whose run is not
clearly visible, proceed as follows:
- disconnect the hose to be replaced from both
sides
- tie a cord to one end of the hose
-remove the hose pulling the cord until it comes
out completely
- untie the cord and tie it to the new hose
- pull the cord from the other side to refit the hose
until reaching the connecting point to the line.
The check of the movement times of the cylinders
shall be done with the hydraulic oil at a temperature
of 60°.

2.22 HYDRAULIC SETTINGS
1.PRELIMINARY OPERATIONS
Warm up the hydraulic oil to 60°C by keeping one of the
elements of the boom distributor to full stroke under
pressure.
To reach this temperature in a faster way, cover the oil
core of the radiator with a carton in the case of a wateroil combined cooler, or the oil radiator if the machine is
equipped with a separate oil radiator.
2.CALIBRATING THE BOOM DISTRIBUTOR
Find the mini-socket for pressure gauge ref. A inside
the frame, under the boom.

Let the diesel engine run at max speed, then move the
boom fully up to end of stroke.
Calibrate valve B of the distributor to 280 bar while
keeping the lifting cylinder at end of stroke and under
pressure and the diesel engine fully accelerated.
In order to check the setting of the safety valve of the
bucket tilting cylinder C (annexes 1), proceed as follows:
• By means of valve B set the distributor pressure to
300 bar while moving one of the cylinders to stroke
end.
• With the engine running at maximum speed, tilt the
forks to one direction by means of the joystick and
act on one of the two valves C until reaching a
pressure of 290 bar.
•Proceed in calibrating the second valve C by tilting
the forks to the opposite direction.
• When both fork inclination safety valves have been
calibrated, reset the pressure control valve B to 280
bar by adjusting the register.
Connect a 0-400 bar pressure gauge to the mini-socket
ref. A.
Extend the boom to end of stroke with the diesel engine
fully accelerated and check that the pressure on the
pressure gauge connected to socket A is 150 bar.
Otherwise, act on valve X (annexes 4).

TECHNICAL SPECIFICATIONS
The control unit also supplies the 5VDC power signal to the joystick/proportional button (+/- 5%).
When the joystick/proportional button is in the central neutral position, the relevant analog signal is 50% of the
power signal.
The dynamics of the joystick signal changes from max 87.5% (joystick/pushbutton to one end) to min. 12.5% (the
opposite end) for the joystick installed in the driving cab, and from max 90% to min. 10% for the joystick installed
on the platform's buttons panel (the percentages are referred to the power signal of the joysticks/proportional
button).
During normal operation (no anomalous condition detected), the red LED of the control unit flashes with a sequence
of 3 seconds ON and 0.25 seconds OFF (say it switches off for a short instant every 3 seconds).
The control unit can detect the following malfunctions:
-Joystick and/or proportional button not in the central neutral position when the Jobsite/OFF/Platform selector
is on Jobsite or Platform (Alarm code 1)
-ON/OFF buttons in the ON position when the Jobsite/OFF/Platform selector is on Jobsite or Platform (Alarm
code 1)
32
Such conditions would activate the manoeuvres associated to the button without control if the signal were not OFF
when the Jobsite or Platform mode is selected. Therefore,until the control unit does not detect a neutral position,
the function is inhibited and the malfunction is signalled.
-Joystick and/or proportional button with analog signal below the minimum threshold (this case also includes
the disconnection of the joystick/porportional button connection or the short circuit to ground of the proportional
signal or the short circuit to ground of the power signal of the joysticks/proportional button) (Alarm code 2)
-Joystick and/or proportional button with analog signal above the maximum threshold (this case includes the
short circuit to VBATT of the power signal or the ground disconnection in the joystick or proportional button
connector) (Alarm code 3)
The malfunctions detected by the power unit are signalled by the red LED which remains OFF for about 2 seconds
then flashes for a number of times equal to the code number associated to the detected alarm. The more the LED
flashes, the more serious is the alarm and serious alarms have priority with respect to the "soft" alarms. In presence
of more alarms, the most serious one is displayed first and, as soon as this is solved, the next one (whose seriousness
was lower) is displayed.

2.25 REAR THREE-POINT HITCH
AGRILIFT 737 - 1037
TECHNICAL SPECIFICATIONS
2
55
• OPERATION OF THE THREE-POINT HITCH
1 - Arms lifting phase
The lever of the distributor shaft (pos. 1 tab. 7) lets the
oil coming from the pump reach the rear part of the pilot
valve (pos. 23 tab. 7) through a transversal hole inside
the distributor body. As the upper surface of this valve
is greater than the lower one, the thrust upwards prevails
and the valve remains closed. The oil at pressure can
therefore flow into the cylinder through the valve (pos. 9
tab. 7) and push the piston (pos. 10 tab. 2) inside the
cylinder (pos. 6 tab. 2), thus resulting in the arms lifting.
2 - Neutral phase (arms stop)
The shaft of the distributor moves to such a position
that the oil at pressure acting on the pilot valve (pos. 23
tab. 7) and keeping the same closed, is drained through
a longitudinal groove located in the distributor body.
In this way, the oil coming from the pump exerts a thrust
on the rear part of the valve which opens and lets the
fluid flow toward the internal body of the hitch, and not
toward the cylinder.
3 - Arms lowering phase
By operating the lever (pos. 3 tab. 7), the shaft of the
distributor connected to same, opens the drain valve
(pos. 14 tab. 7) and, thanks to the action of the hitch
piston, allows the oil to flow to the drain line.
The pressure relief valve (pos. 7 tab. 1), placed on the
body of the hitch, is calibrated at a pressure of 200 210 bar, that is some 20 bar higher than the one of the
pressure relief valve of the hydraulic circuit of the
machine.
• ADJUSTING THE SENSITIVITY
For an efficient control of the position of the implement,
the sensitivity of reaction of the distributor shaft should
be adjusted at best. Such sensitivity depends on the
position of the cam on the distributor shaft with respect
to the cap of the drain valve (pos. 14 tab. 7).
Such position can be changed using the external
adjustment ring nut (pos. 21 tab. 7) as follows:
- Undo the screw (pos. 17 tab. 7) and remove the
external lever (pos. 19 tab. 7).
- Fit the implement you want to use to the three-point
linkage system of the machine.
- Start the engine and let it run at normal speed, then
lift the implement.
- Screw down the adjustment ring nut (pos. 21 tab. 7)
until the load jumps slightly.
- Unscrew the ring nut so the movement stops.
- Refit the external lever (pos. 19 tab. 7) in the position
shown by the relevant screw.
During work, adjust the sensitivity (if necessary) using
the external ring nut.

TECHNICAL SPECIFICATIONS
• WORK IN CONTROLLED POSITION
The controlled position is used for any kind of labour,
and especially for ploughing, as it adjusts and keeps
the traction effort of the machine constant in relation to
the type and condition of the ground being worked.
By partially lowering the external lever (pos. 12 tab. 5)
operating the controlled position, the internal levers
connected to it, make the distributor shaft (pos. 1 tab.
7) rotate. This rotation opens the oil drain ducts from
the cylinder and causes the arms to move down (draining
phase).
The proportionality between stroke of the external control
lever (pos. 12 tab. 5) and stroke of the lifting arms is
automatic, as the rotation of the arms supporting shaft
(pos. 1 tab. 2) connected to the control levers, causes
the distributor shaft to rotate. With the oil flowing through
the special openings during rotation, the initial conditions
are restored and the shaft moves back to the neutral
position.
56
• WORK WITH CONTROLLED EFFORT
This function is used to move the implement to a fixed
depth regardless of the ground conditions and the
traction effort exerted by the machine.
Lowering the external lever of the controlled effort (pos.
6 tab. 5) makes the distributor shaft (pos. 1 tab. 7)
rotate. Inside the end of the shaft, there is an eccentric
pin supporting the control lever. This lever, the internal
ones connected it and the eccentric pin, make the
distributor shaft rotate clockwise, thus resulting in an oil
discharge and the consequent lowering of the arms.
The lowering phase is continuous and total, unless an
external cause (load reaction) intervenes which, by
pressing on the feeler pin (pos. 13 tab. 6), directly
connected to the third point of the system (leaf springs)
of the machine causes the internal lever to move which,
being connected to the distributor shaft, make it rotate
and, as a result, make the arms lift.
In this way, an adjustment action of the lifting arms
occurs in relation to the effort of reaction exerted by the
implement fitted to the three-point linkage system of the
tractor.
The control lever of the controlled position can only
be operated with the controlled effort lever fully up.
The control lever of the controlled effort can only be
operated with the controlled position lever fully up.
