TECHNOLOGY/PRODUCT:
Two-wheel double axle tractor prototype -
Pedestrian Tractor
|
COMPETITIVE ADVANTAGE
- Mechanisation of land preparation is necessary for
its timely performance to meet the strict time
schedules of double cropping of rice.
- A major problem in rice land preparation is soft soil
trafficability and the lowering of the hardpan
by the 4 wheel tractors.
- 2-wheel pedestrian tractors are lighter and able to work
in soft soil areas (about 20-25% of rice land) where 4 wheel tractors cannot be used.
- The annual importation of about 1000 units may be
substituted by the local design and manufacture of the
pedestrian tractor.

DESCRIPTION
General description
- The machine is a double axle pedestrian
tractor prototype designed and developed for rice land cultivation by MARDI for
local manufacture.
Technical Specifications
- Power is transmitted from a 12-14 hp engine to the
transmission unit through vee-belt and pulleys.
- The transmission unit has a gear reduction of 9:1
and a final drive of sprockets and chain.
- Rotary tiller of 72 cm cutting width
- Single rim cagewheels of 100 cm diameter

PERFORMANCE
- The rate of work varied from 0.2 to 0.4 ha/h depending on the
the depth of cultivation. It was greatly affected by the absence or presence of standing water
as soil cutting resistance was very high when the soil was dry.
- A 12 hp engine was found to be about adequate for a 72 cm soil cultivating width in general.
In deep soft soil situation, a 14 hp engine should be used.

TECHNOLOGY STATUS
- Comparative testing of all available pedestrian tractors to
determine the design features desirable in a Malaysian pedestrian tractor has been completed
and reported in MARDI Report No. 131.
- A study on the status and constraints in the manufacture of the Malaysian Pedestrian
tractor in particular and agricultural machinery in general has been completed
and reported in MARDI Report No. 153.
- Studies on the feasibility to locally manufacture it gave an estimated total production
cost of about twice its current market price. The machine design and the production process
are to be simplified to reduce the production cost.
