2. USE AND TECHNICAL DESCRIPTION

2.1 MACHINE USE

AJ 102 or AG 122 type machine with the commercial name STARJET is a two-axle self-propelled mowing machine intended for mowing flat maintained

grass areas with the maximum height of vegetation of 10 cm, e.g. in parks, gardens and playgrounds, or on gentle slopes on which there are no foreign

objects (fallen branches, stones, solid objects, etc.). The gradient of the slope must not exceed 10° (17%).

Always slow down when driving on uneven ground and use ramps when crossing local unevenness higher than 8 cm (curbs). There is a danger of serious

damage to the machine without the use of ramps.

Only the accessories whose utilisation is approved by the machine manufacturer may be connected to the mower.

The use of other accessories means the immediate loss of the guarantee.

2.2 TECHNICAL DESCRIPTION

AJ102 or AG122 type mowing machine consists of the following basic groups:

2.2.1 MACHINE FRAME

The machine frame is welded from steel tubes and metal sheets of 3 mm thickness. It is a supporting element of the engine, gearbox, front and rear axles,

steering, drives, mowing mechanism, accumulator, fuel tank and other essential equipment of the machine.

2.2.2 ENGINE INCLUDING ELECTRICAL INSTALLATION

The engines used in mowing machines are four-stroke petrol engines with a vertical output shaft. The engine is fastened firmly to the frame in the front part

of the machine. The drive from the engine is transmitted to the gearbox by a V-belt. The accumulator is positioned either in a box under the seat or under

the front bonnet depending on the machine model.

2.2.3 GEARBOX INCLUDING REAR WHEEL DRIVE

The gearbox is of a type with a hydrostatic transmission of power. The gear change is carried out by depressing the travel pedal smoothly forwards or back-

wards.

2.2.4 FRONT AXLE WITH WHEELS INCLUDING STEERING UNIT

The front axle is of a massive cast-iron construction. It is suspended on a hollow pivot enabling the swing of wheels. The steering is performed by means of

a steering wheel pinion meshed into a gear segment.

2.2.5 BY-PASS

The by-pass lever serves todisengage and engage the drive from the gearbox to the rear wheels. It is located close by the rear left wheel.

The position of its location in front of the wheel or behind the wheel depends on the machine model.

2.2.6 BONNET AND PLACE OF OPERATOR

The bonnet is made of plastics. The metal parts coherent with the bonnet are protected with powder paint coating. The place of the operator is ergonomi-

cally designed so that all control elements are easily accessible and easy tocontrol. The seat used ensures comfortable operation.

2.2.7 MOWING MECHANISM

The mowing mechanism consists of a cover, main plate, pulleys, shaft with bearings and two mowing blades. The drive of the mowing mechanism is carried

out by a V-belt from the engine via an electromagnetic clutch which is fixed on the output shaft of the engine. The cover made of a thick steel sheet is used

on machines with a mowing width of 102 cm, machines with a mowing width of 122 cm are equipped with a cover made as an aluminium casting.

2.2.8 GRASS COLLECTION BIN

The grass collection bin is constructed of a frame, lid and textile bag. The frame is made of steel tubes.
