Adaptation of a pulling machine for stump
extraction on peat

ABSTRACT
A stump extraction implement was designed and developed
for use with the available soft soil transporter Porter P6-
121. The work involved in the design and adaptation of the
various machine components was described. Functional testing
of the experimental destumping implement was carried out to
evaluate the design concept upon which a prototype unit was
built and developed. From the full-scale field testing of the
prototype unit under farmer's situation, it was found that an
average of four stumps were extracted per working hour. An
analysis of cost of using the destumping implement was
carried out and compared with that of using the mini-
excavator and with that of manual methods. The destumping
implement was found to be more suitable for small-scale and
occassional clearing of stumps and logs in peat.

Alat tambahan untuk mencabut tunggul-tunggul kayu dari
tanah gambut telah direkabentuk khas untuk digunakan dengan
jentera penggerak asas, Porter P6-121. Kerja-kerja yang
terlibat dalam merekabentuk dan penyesuaian alat tambahan ini
dihuraikan. Ujian alat tambahan ini dijalankan untuk menilai
kesesuaian konsep rekabentuk berkenaan. Hasil daripada kajian
ini, seunit prototaip alat tambahan telah dibina dan diuji
seluas-luasnya di ladang-ladang petani. Pada puratanya empat
tunggul pokok getah dapat dicabut dalam masa satu jam.
Analisis ekonomi juga dijalankan untuk membandingkan kos
mencabut tunggul di antara alat tambahan dan sebuah jenkaut
kecil (mini-excavator). Alat tambahan didapati lebih sesuai
digunakan untuk mencabut tunggul sekali-sekala dan bukan
sekali meluas.
