| Abstract | An attempt was made to design a hydraulic power transmission and a mounting
frame with hydraulic lifting mechanism to provide adjustable cutting height for a front
mounted pineapple plant dressing machine previously developed. The machine had four
blades of 0460 cm, with a spacing of 70-60-70 cm. The tractor used was a MasseyFergusson tractor MF 185. Power was taken from tractor pto through a chain-sprocket
step-up transmission. Hydraulic motor used was a low speed and a step-up transmission
was used to obtain high blade speed. The developed hydraulic transmission and lifting
mechanism could perform well although still some improvements are needed.
Field tests were conducted in pineapple plantation. Because of unsatisfactory
performance using four blades, only two blades were used. Short time field testing
revealed that the field capacity was 0.22 ha/h and field efficiency was 72.3%. Cutting
effectiveness was 93%, plant damaged was 0.3%, and height of cut was 35.5 cm. Net
torque to drive one blade at normal conditions was estimated to be 5.4 N.m. Maximum
torque at motor shaft was 342 N.m. However, when blade shafts were wrapped and
clogged by weeds and cut leaves, the machine was likely to stall. A long term testing is
necessary to estimate the accurate field performance of the developed machine. |
