1. INTRODUCTION
Note:
L-H007-1104EN
This manual covers the Lely Tigo 35S(T) Classic, the Lely Tigo 35S(T),
the Lely Tigo 40S(T) and the Lely Tigo 50S(T) in all variants and with all
options
to your specific model.
The Lely Tigo S is a loader wagon to pick up, cut and collect mown fodder
crops from a swath. It has the following main components:
• a drawbar that can be adjusted in height to match the tractor coupling
• a pick-up unit that picks up the fodder crop and passes it to the cutting unit
• a cutting unit that chops the fodder crop and thrusts it into the carriage
• a carriage with:
• an under-carriage with a single axle or tandem axle
The pick-up unit and the cutting unit are driven by the Power Take-Off (PTO)
of the tractor.
The floor conveyor and hydraulic rams are driven by the hydraulic power
provided by the tractor. The hydraulic control valves are operated either
manually or electrically via a control panel in the tractor cabin.
available. Therefore, parts of this manual may be not applicable
system and optionally to tilt the wagon
• a superstructure to contain the fodder crop
• a floor conveyor to aid loading and unloading
• a tailgate to unload the carriage
Electrical power for the lights and the (optional) electric control system and
signals for braking lights and direction indicators are also provided by the
tractor.

1-2 Introduction
1.2 Drawbar
The drawbar can be either:
straight with a rigid coupling eye
•
• low with a coupling eye that can swivel
The drawbar can be adjusted in height either:
• manually by turning an adjustment spindle (height adjustment range
approximately 30 cm to match the height of the tractor coupling system)
or
• hydraulically (to tilt the wagon to facilitate unloading on a silage clamp. The
maximum clearance between the ground and the pick-up is approximately
70 cm).
The overrun brake (if present) and the parking brake (safety brake) are
integrated with the drawbar. In the case of an overrun brake, the wheels are
provided with a mechanism to allow reverse driving. The parking brake lever
has a nylon break-way rope that shall be attached to the tractor to engage the
parking brake in the event that the coupling fails during riding.
Furthermore, there is a parking jack installed on the main frame. The height of
the parking jack can be adjusted by a telescopic bottom part and turning a
crank.

1.3 Pick-up Unit
The pick-up unit picks up the fodder crop from the swath and conveys it to the
cutting unit. The pick-up unit has 5 bars with tines at 54 mm clearance for
optimal pick-up behaviour.
The guide wheels at the sides of the pick-up unit can be adjusted in height to
the pick-up unit follow the terrain contour at the optimal elevation. The guide
let
wheels can be either:
• fixed
or
• swiveled
The wind guard in front of the pick-up unit minimises fodder crop losses due
to air turbulences. It can be adjusted in height to cope with the swath thickness
and the properties of the fodder crop. Optionally, there is a wind guard available
with a roller for short crops.
Two hydraulic rams (one at each side) allow to raise the pick-up unit when
making turns or when travelling over the public road.
The pick-up unit has a built-in protective freewheel clutch that allows the rotor
with the tines to rotate freely in the event that the tines touch the ground when
driving reverse.

1-4 Introduction
1.4 Cutting Unit
The rotor of the cutting unit has 3 or 5 cylindrical bars in bearings with tines
thrust the fodder crop from the pick-up unit through an assembly of knives
that
into the carriage. There are 2 tines per knife (one at each side of the knife).
Each tine bar has a lever with a roller. The roller follows a flattened circular
track (cam track) so that the tines make a swinging movement upon each cycle
of the rotor. As a result, the tines maintain a horizontal attitude from a point
somewhere between the knives up to the point where they are withdrawn from
the conveyor channel. This causes the cut fodder to be pushed upwards into
the carriage.
The knife assembly can have two groups of knives. The upper group is always
present and is divided into two sub-groups. It can have 17 knives at maximum.
The lower group is optional and can have 16 knives at maximum. Using the
Lely Tigo Tool, each group or one of both sub-groups can be moved in and
out. This allows to have 5, 17, 21 or 33 knives in, thus different cut sizes down
to 38 mm. Because small cut sizes are normally used for silage forage, the
optional lower knife group is also called the 'silage knife group'.
With two optional hydraulic rams (one at each side), it is possible to move out
all knives at once, for example to solve a blockage problem.
The knives are kept in place by buckle springs that let them deflect when
foreign objects pass the cutting unit.This Trimatic™ release system prevents
damage to the cutting unit.
L-H007-1104EN
The knife assembly can be easily detached and rolled out on (optional)
transport wheels. Knives can be taken out by hand individually for sharpening
or replacement.

1.5 Carriage
1.5.1 Superstructure
Usually the carriage will be enlarged with a superstructure. This can be either:
an open superstructure consisting of 4 posts, a bow and lattice side walls,
•
a semi-closed front wall, a rear tarpaulin, 14 rigging ropes at the top and 2
rigging ropes at the sides. Optionally there can be a front-top tarpaulin
(recommended for loading short cut fodder crop).
or
• a (relatively) closed superstructure with closed metal plate side walls, a
semi-closed front wall, a rear tarpaulin and 14 rigging ropes at the top
The open superstructure can be folded down to park the wagon in a barn or
hangar. Folding up and down can be done either:
• manually using a rocker lever
or
• hydraulically

1.5.2 Floor Conveyor
Upon harvesting, a pile of fodder builds up above and behind the conveyor
channel of the cutting unit. Periodically, the floor conveyor must be activated
shift the pile towards the (closed) tailgate to keep the conveyor channel open
to
and to compress the fodder crop. The floor conveyor is also used to unload
the carriage.
The floor conveyor consists of a wooden floor with two parallel metal gutters
and equidistant metal slats. The slats are dragged over the floor by closed loop
chains in the gutters. The chains are driven by an hydraulic motor that can be
operated:
• from a control valve near the motor
and
• from a second control valve that is either:
• part of the tractor hydraulic system
or
• electrically controlled from the operator panel in the tractor cabin

1.5.3 Tailgate
The tailgate hangs from the tailgate boom bar with 3 hinges and is locked at
the bottom-left and bottom-right side. The locks can be unlocked with a lever
at the rear left-bottom side of the carriage.
There are also latches at the top-left and top-right side of the tailgate. These
are operated with a lever at the rear side of the tailgate. When locked, the
tailgate can be lifted to a wide open position using the left and right hydraulic
lifting arms. Lifting and lowering is done from the control panel in the tractor
cabin.The locks at the bottom-left and bottom-right side of the tailgate open/
close automatically in this case.
Whether the tailgate must be just unlocked or wide open depends on the
overhead space available at the unloading site. Use wide open whenever
possible.
The button on the wire mesh on the inside of the carriage serves as a sensor
to detect the carriage full status.

1.5.4 Under-carriage
In case of a single wheel axle, the axle is fixed to the under-carriage without
springs. For the tandem axle version, both wheel axles are suspended from
packages of leaf springs. The wheels are fixed (i.e. not steered). Various tyre
types are available.
All wheels are provided with a brake that can be activated:
mechanically by the parking brake
•
and
• mechanically by an (optional) overrun mechanism that is activated when
the tractor slows down or when riding downwards from a slope (however,
a freewheel mechanism in the wheels allows reverse driving)
or
• hydraulically by a hydraulic brake signal provided by the tractor
or
• pneumatically by a pneumatic brake signal and pneumatic power
(compressed air) provided by the tractor
In the case of a pneumatic brake ram, the brake force can be adapted to the
load in the carriage. This can be done either:
• manually via a lever (4 settings)
or
• automatically (Automatic Load-sensitive Brake system, ALB). For this
system, the lever that controls the brake force valve is connected to the leaf
spring package. The further the leaf springs deflect, thus the more load, the
higher the brake force.
If there are two wheel axles and hydraulic or pneumatic brake rams, the parking
brake is only connected to the front wheel brakes.
Optionally, mudguards can be mounted above the wheels.

Introduction 1-15
1.6 Hydraulic System
The hydraulic system can be used in combination with three different types of
tractor hydraulic systems:
conventional fixed displacement pump (the pump runs continuously and a
•
valve recycles the over-pressure)
• load sensing system (the pump capacity is controlled to deliver pressure
and flow on demand)
• closed centre system (the pump runs continuously but there is no recycle
flow if no valve is operated)
Most of the control valves are either:
• in a control panel in the tractor cabin (manually controlled valves)
or
• electrically controlled by an electric control panel in the tractor cabin
(Comfort system). In this case, the control valves are mounted under a
cover at the front-right side of the carriage.

1.7 Drive System
The pick-up unit and the cutting unit are driven by the PTO connection of the
tractor. The transmission is as follows:

4. The lateral shaft drives the rotor of the cutting unit via 3 gearwheels.
5. The middle gearwheel drives the pick-up unit via:
6. The pick-up unit shaft with the sprocket wheel drives the rotor with the
PTO of the tractor drives the telescopic PTO shaft of the Tigo. This
PTO shaft can be either:
• wide angle (max. 70°) at the tractor side and normal angle (max. 35°)
at the Tigo side
or
• wide angle at both sides (recommended in case of a movable
hydraulic drawbar)
disengage the lateral shaft. The lever for manual operation of the clutch
is at the front side of the Tigo. If the pick-up unit is lifted, an override
mechanism disengages the clutch, independent of the clutch lever
position.
• a sprocket wheel/chain transmission to a double sprocket wheel on
a mount on the main frame
• a sprocket wheel/chain transmission from the double sprocket wheel
to the sprocket wheel on the shaft of the pick-up unit
This configuration of two sprocket wheel/chain transmissions allows
the pick-up unit to be lifted/lowered.
tines via a freewheel clutch.
The overload protection on the PTO shaft is dedicated to the Tigo and prevents
damage to the cutting unit when it is jammed by a foreign object. If the shaft
torque exceeds 1400 Nm, the overload protection cuts off the transmission.
The overload protection can be reset by disengaging the dog clutch at low
rotational PTO speed (remove the blockage before engaging the clutch again).
The freewheel clutch of the pick-up unit allows the tines to rotate freely and,
therefore, protects the tines when the pick-up unit is not driven and the tines
touch objects on the ground during reverse driving.

1.8 Control Panel
Most functions can be operated from a control panel that can be installed in
the tractor cabin. The control panel can be either hydraulic or electric.
1.8.1 Hydraulic Control Panel
The hydraulic control panel is connected to the tractor and the Tigo with
hydraulic hoses and has a mount that allows to install/uninstall the panel by
hand. The valves in the hydraulic control panel are to select a device, not to
extend/retract the corresponding ram. This is done via a control valve of the
tractor.
