2.0 MACHINE STRUCTURE<br />
It is vital to know the machine's structure in order to ensure safe and<br />
efficient operation and maintenance. This section covers the machine's<br />
structure, i.e. locations and names of the main components.<br />
Detailed instructions for operation and maintenance are provided in<br />
sections 04 Cabin and controls, 05 Driving and use and 06 Maintenance.<br />
Varoitus! Varning! Warning!<br />
The rear‐wheel steered <strong>LM</strong> Trac <strong>286</strong> is a special machine designed for<br />
property maintenance and garden work only. Using the machine for<br />
something it is not designed for is forbidden and the manufacturer is not<br />
responsible for any damage caused in such use or as a result thereof.<br />
In order to use the machine effectively, familiarise yourself with its<br />
operating principles. Taking into account the lightness of the machine<br />
and rather low power, you must master its special features in order to<br />
achieve great performance both quantitatively and qualitatively.<br />
<strong>LM</strong> Trac <strong>286</strong> has a component structure so maintenance and repairs are<br />
quick and easy to perform.<br />
The power source, Lombardini LDW1603 CHD Plus diesel engine, and<br />
the connected drive‐, working‐ and steering hydraulics pumps form a<br />
single entity. This entity is mounted on the body with rubber pads so<br />
that the engine vibrations are not transmitted to the body creating<br />
undesired noise and vibration. The safety cabin is also mounted on the<br />
body with rubber pads to minimise undesired noise.<br />
Tools are mounted on the tool mounting in front of the machine, e.g.<br />
the A frame.<br />
The fuel and hydraulic oil tanks and the battery are located low on the<br />
sides of the body to achieve a low centre of gravity. The machine is<br />
equipped with rear‐wheel steering.<br />
The efficient use of the <strong>LM</strong> Trac <strong>286</strong> machine requires that the driver<br />
understand the principle of the machine's driving automation.<br />
The drive power train is fully hydraulic, which enables highly flexible<br />
driving forwards/backwards.<br />
The double action drive pedal is used for the operations performed in<br />
the traditional mechanical power train by the clutch/brake pedal and for<br />
directional changes.<br />
When the drive pedal is pressed with the ball of the foot the machine<br />
moves FOREWARD and with the heel BACKWARDS.<br />
The position of the drive pedal affects driving speed and direction<br />
through the amount of oil provided for the hub motor. The rotation<br />
speed of the motor is regulated by a separate hand throttle. In practice,<br />
the hand throttle is used to set a suitable motor rotation speed and the<br />
drive pedal is used to select the driving direction and speed. When<br />
pressure on the drive pedal is released, an automatic braking action<br />
resulting from the hydrostatic power train takes place while driving both<br />
forwards and backwards.<br />
Using the brake pedal is usually only necessary to keep the machine in<br />
place on a sloping surface, for example.<br />
<strong>LM</strong> Trac <strong>286</strong> machine's speed ranges:<br />
2‐WD: Fast 0–20 km/h Slow 0–10 km/h<br />
Reverse:<br />
Always 10 km/h<br />
4‐WD: Fast 0–13 km/h Slow 0–6.5 km/h<br />
Reverse:<br />
Always 6.5 km/h<br />
A three‐cylinder freely breathing diesel engine rotates the variable<br />
displacement axial piston pump. The pump operates the two‐speed hub<br />
