PRESENTATION/CONTENTS
ALL HYDRAULIC
•Drive transmission
•Differential lock
•Steering
•Grassbox lifting
•Grassbox opening
•Tool-holder triangle
•Power take-off
STEERING
•Height and angle-adjustable column
•Hydraulic assistance (Power steering)
NB : The steering wheel effort depends on the rotational speed of the steering wheel and on the
engine speed.
•Track width : 1.18 m
•Turning radius (outer front wheel) : 2.5 m
•Radius of non-mown surface : 1.25 m
•Pendular axle : ±4.5°clearance
•Tyres : 16 x 7.5 / 4 ply / 1.2 bar (front and rear)
NB : the tyre pressure is the pressure exerted on the ground, that is approximately 1.2 kg/cm2.
•Load distribution : rear 70% / front 30%
CUTTING SYSTEM
•Two counter rotating blades indexed at 90°.
•Blades driven by a single belt. This allows the loss of power to be reduced as much as
possible, as one belt absorbs 10% of the power (friction…).
•Removable side parts (made safe by presence switches) for easy access to the blades
(shear bolts, sharpening…).

ENGINE
Arguments
1) All the technology of a modern high-performance engine
- 4-stroke diesel engine
- In-line cylinders
- Liquid cooling
- Injection with injector pump on the cylinder head
- Distribution by overhead camshaft
- Camshaft drive by notched belt
- Double power take-off on the crankshaft
- Power take-off on the camshaft
- Pressure lubrication with lobe-type pump on the crankshaft
- External total pass oil filter
- Water pump in the block
- Automatic fuel supplement for starting
- Centrifugal speed regulator
- Cast iron monobloc cylinder housing
- Aluminium cylinder head
- Reborable cylinders
2) Accessibility to the parts for control, cleaning and replacement.
- FOCS technology : the engine has all the control and regulation components together in the
cylinder head (camshaft, injector-pump, speed regulation). This allows easy access to all the
filter parts (air, fuel, oil, radiator grilles) and liquids ( coolant, oil)
3) Silent engine thanks to the technology used (indirect injection, camshaft drive by notched belt) and
to the optimisation efforts made by the manufacturer.
4) Air filtering with DONALDSON
®
filter with safety cartridge that guarantees the engine a very long
service life.

COOLING SYSTEM.
A thermostatic valve allows the engine to come up to its operating temperature more rapidly from cold
(starting), hence 2 possible routes of the coolant (main and by-pass circuits).
