TECHNOLOGY/PRODUCT:
A tracked tractor for peatland -
PEATTRAK
|
COMPETITIVE ADVANTAGE
- The design and fabrication of
MALTRAK, a 43.5 hp transporter
complete with Power Take Off and three point linkage
facility, were carried out in 1986 with the assistance
of Howard Alatpertanian Sdn Bhd.
- Field tests on MALTRAK in 1986-1987
showed that it is not very suitable for as a tractor for field operations
that require high power or precision control. This is because it was designed
as a transporter.
- A tracked tractor is needed for efficient mechanised crop production
on peat.

PERFORMANCE
- The machine can be driven in the opposite direction
with the operator sitting on the instrument dashboard so
that the implement is in front of the operator.
- It can carry up to 1000 kg load on established peat
where the water table level is more than 30 cm below
the soil surface.
- It can travel up to 15 kph (unladen).
- A workrate of 0.3-0.6 ha/h for rotary cultivation was
recorded depending on the depth of cultivation
and softness of the soil.
- A workrate of 0.2-0.4 ha/h for rotary slashing of old
pineapple plants and shrubs was recorded depending on the
thickness of the vegetation.
- It can cross field drains of up to 30 cm wide without
the need for bridges.
- On peat, it can provide a drawbar pull of up to 1000
kgf when empty and up to 2000 kgf when carrying a 1 tonne
load.
|
TECHNOLOGY STATUS
- PEATTRAK is suitable for mechanisation of various operations in
crop production on peat soil, that is cleared of wood obstacles, such
rotary tillage, rotary slashing, row seeding/sowing, bedforming,
peaticides boom spraying and lime broadcasting.
- It is useful to estates where the soil is peat or very soft
or the terrain is undulating.
- Commercial production of the tractor has not yet been exploited.
