AT the recent Oil and Fats International Congress in Kuala Lumpur, something familiar caught my attention amid discussions about oils and fats.
An oil palm harvesting pole, but this time an electric cutter developed through a private-sector initiative led by Puan Sri Datuk Sandra Lee.
Having heard about the innovation from Sabah, I finally travelled to Kuala Lumpur, only to catch up with a harvesting pole!
My curiosity was understandable. I began as a plantation researcher before moving into corporate management and industry leadership, including involvement with the Malaysian Palm Oil Consortium for Mechanisation and Automation (Marcop).
Never quite the conventional estate planter, I nevertheless spent considerable time visiting estates, engaging with managers, researchers and workers, and occasionally busybodying around to offer tough love and challenge entrenched practices.
Progress often begins with uncomfortable questions, preferably with one’s boots firmly on the ground.
That electric cutter revived a decades-old challenge. How can harvesting become less physically demanding, more productive and economically sustainable as palms grow taller and labour becomes scarcer?
Perhaps the next breakthrough lies not in one extraordinary machine, but in refining familiar tools, integrating smarter field systems and turning promising technologies into everyday plantation practice.
From bamboo to carbon fibre
For generations, harvesting depended on two familiar implements: the chisel for shorter palms, and the curved sickle mounted on long poles for taller palms.
Bamboo as galah was once the material of choice. Relatively light and readily available, it nevertheless suffered from flexibility, inconsistent durability and limitations in reaching taller palms.
Researchers subsequently developed aluminium-alloy harvesting poles, improving strength and consistency.
The evolution did not stop there. Graphite and carbon-fibre composite poles have introduced another advance, combining lighter weight, stiffness and extended reach.
Telescopic and modular designs allow harvesters to access bunches on taller palms while reducing the fatigue associated with repeatedly lifting and maneuvering long poles.
Some specialised composite poles also offer electrical insulation, subject to design, certification and operating conditions. Durability and economics require field evaluation.
These developments remind us that innovation does not always require an engine or battery. Sometimes, changing the material in a familiar harvesting pole can make a meaningful difference to the worker holding it.
Yet cutting power still largely came from human muscle. As palms grew taller, every additional metre increased the challenge of balance, control and physical effort. The next ambition was obvious. Could an engine do the cutting?
When the pole acquired an engine
The Malaysian Palm Oil Board’s petrol-powered harvesting cutters developed during the 2000s represented an advance. Mechanical power assisted cutting while workers positioned and controlled the pole.
But mechanisation introduced new problems. Engines added weight, vibration, noise and maintenance requirements. A machine might cut faster but leave its operator struggling to hold and maneuver it.
Subsequent refinements reduced weight and vibration while improving reliability and cutting efficiency.
Researchers also experimented with hydraulic harvesting platforms and tracked vehicles.
While these transferred equipment weight from workers to machines, they introduced difficulties involving cost, accessibility, slopes and maneuverability.
Plantations, after all, are not factory floors. And gravity has never been particularly impressed by engineering presentations. The lesson became increasingly clear. Harvesting mechanisation must be judged not merely by cutting speed, but by reliability, ergonomics, maintenance, affordability and suitability for actual estate conditions.
Enter the electric cutter
Battery technology opened another chapter. Electric cutters offered the potential for quieter operation, reduced vibration and fewer routine engine-maintenance requirements.
Research institutions and private-sector developers began exploring battery-powered alternatives.
Electricity does not guarantee better performance. Battery endurance, weight distribution, charging, replacement costs and after-sales support remain critical.
The real question is not whether petrol or electricity is fashionable. It is which technology delivers better overall performance under actual estate conditions.
Sandra Lee’s background spans business, heritage conservation and community service rather than conventional plantation engineering.
Her interest in mechanisation emerged during the Covid-19 pandemic, when labour shortages exposed the vulnerability of plantation operations.
With technology partners, she developed electric harvesting equipment through repeated field trials and redesigns.
What interested me was not simply the equipment but the persistence behind it. Having enjoyed considerable success in other pursuits, she could reasonably have chosen a more comfortable occupation than experimenting with harvesting poles.
Sandra also shared a humorous anecdote about a newspaper photograph showing her holding the electric cutter rather menacingly.
She joked that she resembled the Grim Reaper, although armed with a powered harvesting cutter rather than the traditional scythe. Her husband, Tan Sri Lee Oi Hian, apparently remarked that he might need protection!
Perhaps Lee was merely demonstrating his appreciation of occupational safety. But behind the humour lies a serious point. Innovation requires curiosity, perseverance and the willingness to venture beyond familiar territory.
Whether such inventions ultimately succeed must still be determined by their performance, reliability and economics in the field.
The broader lesson extends beyond any individual entrepreneur. Innovation needs curiosity and perseverance, but successful commercialisation also requires evidence, refinement and sustained industry support.
The plantation as a laboratory
One persistent challenge is the distance between prototype development and commercial adoption.
A machine may perform impressively during a demonstration yet struggle under actual plantation conditions.
Terrain, palm height, rainfall, operator skill and maintenance arrangements can profoundly influence performance.
Equipment must therefore be tested across representative estates, preferably with independent evaluation.
Such trials should measure more than bunches cut per hour. Labour hours per tonne, equipment availability, maintenance costs, crop recovery, worker fatigue and overall operating economics provide a more meaningful assessment.
The experience of harvesters themselves is especially valuable. They know when a pole becomes uncomfortable, when its balance is wrong and when a seemingly minor inconvenience becomes a serious problem after several hours.
We should listen to them early in equipment development, not merely ask them to accept machines designed elsewhere.
Researchers, manufacturers and plantation operators must work together to turn field feedback into engineering improvements and commercially dependable equipment.
The low-hanging opportunity
The industry has made considerable progress in mechanising harvesting for younger, shorter palms, but taller palms remain a formidable challenge as greater height demands longer reach, better balance and more sophisticated engineering. Both deserve continued attention.
However, rather than waiting for the elusive breakthrough in tall-palm harvesting, I believe we should accelerate the refinement and wider adoption of existing technologies for shorter palms, while progressively extending their reach and capabilities.
After all, mechanisation need not conquer the tallest palms before delivering meaningful gains closer to the ground.
Malaysia has approximately 5.7 million hectares under oil palm. Even a modest proportion of younger palms represents a substantial opportunity to accelerate harvesting mechanisation.
Compact powered chisels and sickles and improved electric cutters could potentially reduce repetitive physical effort in shorter palms, while lightweight composite poles may offer advantages in taller stands.
A practical starting point would be to identify estates with suitable palm heights, conduct comparative trials and progressively expand adoption where results justify investment.
Cutting faster is not harvesting better
We must also remember that harvesting does not end when the bunch falls. Fruit must be collected, loose fruits recovered and crops evacuated efficiently.
A faster cutter may merely shift the bottleneck from the palm crown to the ground.
The objective should therefore be fewer labour hours per tonne of recoverable crop, not simply more bunches cut per hour.
Mechanised wheelbarrows, improved collection equipment, motorised transporters and better harvesting paths can complement powered cutting tools.
Every unnecessary movement of a fruit bunch consumes time and effort. Reducing repeated handling and improving access may sometimes deliver greater productivity gains than increasing cutting speed alone.
Terrain remains another major constraint. Equipment suitable for flat estates may require substantial adaptation for steep slopes, terraces and wet conditions.
There is no universal machine for every plantation. The challenge is to match appropriate technologies with specific field conditions while improving the entire harvesting and crop evacuation system.
Even robots need a cutting edge
Looking ahead, robotics and artificial intelligence offer exciting possibilities. China and other countries are advancing rapidly in machine vision, battery technology and agricultural automation.
Future harvesting robots may identify ripe bunches, navigate estates and position cutting tools with minimal human intervention.
Yet even the cleverest robot must still sever the bunch stalk, requiring an effective cutter mounted on a pole, mechanical arm or robotic boom.
Artificial intelligence (AI) may provide the eyes and brain, but the cutting mechanism must do the work. A robot that recognises a ripe bunch but cannot cut it is rather like a brilliant student who knows all the answers but cannot hold a pen.
Today’s electric cutter could become tomorrow’s robotic cutting mechanism. Hence, continued improvements in blade design, lightweight materials, power systems and durability remain essential.
Even AI needs a good cutting edge. Powered cutters and autonomous robots are complementary stages of progress, not competing ambitions.
Leadership, funding and collaboration
Technology alone will not transform harvesting. The industry needs purposeful leadership, sustained funding, clear priorities and a coordinated mechanisation agenda.
Malaysia does not lack research institutions, plantation expertise, engineering talent or innovative ideas.
Too often, the missing link is our collective ability to turn promising prototypes into dependable commercial equipment.
MPOB, Marcop, universities, plantation companies, manufacturers and technology developers need stronger collaboration, effective leadership, shared testing opportunities, transparent performance benchmarks and clear accountability.
Promising technologies could progress into larger-scale demonstrations, supported by operator training, maintenance services, financing arrangements and credible after-sales networks.
Funding must support refinement, field validation and commercial adoption. Judge progress by machines working in estates, not prototypes displayed at conferences.
We have spent decades researching how to mechanise plantations. The greater challenge now is to mechanise the process of turning research into results.
Equally important, Malaysia should resist reinventing the wheel. China offers considerable opportunities for technological collaboration in robotics, artificial intelligence, battery systems, precision engineering and agricultural automation, supported by its vast manufacturing capabilities, economies of scale and ability to translate innovation into commercially affordable solutions.
We should move beyond study visits and memoranda of understanding towards joint development, technology licensing and commercially grounded field trials.
Why develop every component from scratch when useful technologies can be acquired and adapted?
Equipment developed elsewhere cannot simply be transplanted into Malaysian plantations. Our terrain, rainfall, soils, palm architecture and harvesting practices demand local validation.
The sensible approach is to learn globally, adapt locally and scale commercially. Otherwise, while we continue reinventing the wheel, our palms will simply keep growing taller.
The next cut belongs to all of us
Mechanisation must deliver more than labour savings. It should reduce physical strain, improve productivity and crop recovery, and make plantation careers more attractive to younger Malaysians through opportunities in machinery, maintenance and digital technologies.
Manufacturers deserve fair trials, not automatic endorsement. Equally, estate managers should not allow yesterday’s disappointments to become excuses for resisting tomorrow’s improvements.
My encounter with Sandra Lee’s electric cutter did not suggest that the harvesting challenge, particularly for taller palms, had been solved.
Nevertheless, her perseverance through 18 engineering iterations is encouraging, with promising improvements in weight, balance, vibration, operator fatigue, battery endurance and expected service life.
Dependable after-sales support, independently verified productivity gains and acceptable returns on investment remain essential.
I salute her determination and believe the innovation is heading in the right direction, while recognising, as Sandra herself agrees, that sustained field performance remains the ultimate test.
Transforming harvesting cannot rest on individual innovators alone. It requires an industry willing to test fairly, invest patiently, collaborate globally and turn promising inventions into practical, dependable solutions.
We recognise the need to replant ageing palms. Perhaps it is equally time to replant our ageing assumptions about harvesting. Progress need not begin by replacing the worker holding the pole, but by giving that worker a better tool, a less exhausting day and a more productive future.
And while we struggle to reach the highest bunches, perhaps the next breakthrough is already within reach.
After all, the real cutting edge of mechanisation lies not in the sharpness of the blade, but in an industry’s willingness to embrace change.
