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

ENGINEENGINE

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).
