In this study the performance of a motorized palm fruit bunch harvester (MBH) was evaluated in comparison with the bamboo-pole-and-knife harvester (BPK). The MBH was first tested on Nigerian plantations for the palm trees it could reach. The average time taken to harvest a bunch and the time taken per hectare of plantation were determined. The best orientation and the cutting angle for the harvester were also determined. The exact height which the harvester could reach was also determined on the plantations. The harvester was later used in comparison with (BPK) method on palms of moderate height and the average time of harvest per bunch, field capacity, as well as cost of operation was determined for the two methods. Time study (TS) of the two methods was also carried out. The result showed that MBH could harvest between the height of 2.5 m and 4.5 m of palm conveniently. The average time of harvest per tree and speed of harvest for MBH and BPK were 98.86 s and 66 bunches/h; and 166.93 s and 40 bunches/h, respectively. This shows that time of harvest for motorized harvester is over 60% lower, and the speed of harvest is over 50% higher than bamboo pole and knife. The time of harvest per hectare for both MBH and BPK are approximately 4 h/ha and 7 h/ha, respectively. The rate of fuel consumption was estimated to be 1.03 L/h. Moreover, the cost of operation for MBH and BPK was estimated to be ₦ 10,223.46 and ₦ 16,950 per hectare, respectively. The cost of operation using the BPK is over 60 per cent more than that of the MBH. Statistical analysis of the effect of time of harvest on methods indicated that the effect was significant (p < 0.05). The study concluded that motorized oil palm bunch cutter can effectively and efficiently handle palms of moderate height in Nigerian oil palm plantations and performed better than the bamboo pole and knife.

A development of oil palm pruner and harvester machinery design implemented in the field still faces a problem due to the lack of effective and efficient design which is need to be solved. It was noted that in order to develop the design, an early data and information of physical and mechanical properties of palm oil frond and stem fruits is critically important. The objective of the research was to obtain the physical and mechanical properties of palm oil frond and stem in order to develop the design of pruner and harvester machinery. The result showed that tool machinery was been advantageous by the physical properties of the plant i.e. the total weight of frond and leaf which enable to support the cutting process. The average of total weight of frond and leaf was 16.8 kg. The diagonal cutting trajectory was been more advantageous because of total weight and frond shape toward to the different of the plant tissue area. The measurement result shows that cutting curve follows the time required for cutting. The comparison among cutting curve shows differences in cutting thickness or length. In this case, the thickness is linear with cutting time. Besides, those curves show differences at the height which determine the maximum value of tested material cutting resistance. Alternative solution for machinery development design is pruner-harvester for height plant below 6 m and among 6 to 12 m. For below 6 m, pruner-harvester was designed by incorporating motor as power source and cutter-disc as the knife cutter. That condition was relied on that estate which was maintenance intensively commonly used cutter-disc. Pruner-harvester above 6 m and up to 12 m was improved based on manual egrekdesigned by adding fresh fruit bunch alley supply glide in order to keep the fruits still in intact form. The consideration was based on affectivity and efficiency. It also considers homogenous ecological of palm oil plant which should be maintained to reduce global warming effect. Information obtained in this research could become positive consideration and alternative solution to provide problem solvingat early development design of palm oil pruner and harvester machinery.
Development of an automatic cutting system for harvesting oil palm fresh fruit bunch (FFB)
AFRICAN JOURNAL OF AGRICULTURAL RESEEARCH, 2012
The purpose of this project was to design, fabricate and test a harvesting mechanism for oil palm fresh fruit bunches (FFB). A carrier machine was designed and fabricated which can move around the tree trunk smoothly while carrying the cutting system. A mechanize motor system also was designed and assembled on the carrier machine for moving the cutting machine forward and backward along the tree trunk radius. For a successful and smooth cutting process, two direct current (DC) motors were used for carrier machine. Cutting machine consists of a mechanism for cutting and a cutting blade. A reciprocating mechanism was used in this project because of the added advantages of this method as compared to others. Design of the blade tooth for doing a fast and clean cut was an important parameter in this project. An HM-TR Transparent Wireless Data Link Module and an ATmega8 microcontroller were used to control the cutting system. This system was tested successfully in both laboratory and field condition.

Mechanization in Oil Palm Harvesting
International Journal of Academic Research in Business and Social Sciences
Harvesting is an important process in oil palm plantation main objective of harvesting is to get fresh fruit bunches with excellent oil content and quality and can get the maximum profit. During harvesting the worker need mechanization to assist in collection of oil palm bunches. Currently there is many types of technological or mechanized tools for aiding the harvesting of palm oil. This paper is to grasp detail understanding on the history of mechanization used in oil palm plantation specifically for harvesting in Malaysia. For the traditional and manual method, wheelbarrow is only the best mechanization in assisted collection of oil palm bunches. It is because wheelbarrow can pass through all types of road surface, the gradient of slope, and type of soil. Wheelbarrow is a machine that is easy to work with and does not give pollution to environment. However wheelbarrow use more energy of worker to pull the wheelbarrow with full capacity. To reduce the use of worker energy, buffalo cart are used to replace the wheelbarrow. Buffalo cart can help to do human work by pulling the cart that full fill with oil palm bunch. Beside can reduce the use of energy, it can reduce the cost of worker and can make the time more short in harvesting system. After that, mechanization assisted in harvesting system is improve by using engine that is mechanical buffalo (Badang and Rhyno). Mechanical buffalo can help human work in plantation sector to more faster. Mechanical buffalo also can reduce the labour cost and can increase the productivity of worker.

Development of a Low Cost Motorized Oil Palm Fruit Bunch Stripper
Oil palm is an economic plant with great importance because of its revenue generation capacity. The major bottleneck in the oil palm fruit processing in Nigeria especially in the small scale oil palm processing industries is the stripping of oil palm fruits from their bunches and most of palm fruit processors are low income earners who might not be able to afford the existing palm fruit bunch stripper due to their high cost. A low cost motorized stripper was developed in order to overcome this challenge. The components of the stripper which consist of a power source, the stripping unit housing, the speed gear and shaft, the stripping unit, fruit and bunch outlets and the supporting frame were fabricated using locally sourced materials.The stripper was tested to evaluate its performance efficiency. Freshly harvested palm fruit bunches at different fermentation time of 24, 36, 48, 60 and 72 hours was used. High fruit stripping efficiency of 98.8% was recorded at fermentation time of 72 hours and lowest of 72.84% at fermentation time of 24 hours. It has clean fruit recovery efficiency of 98.57% at 60 hours fermentation and lowest average value of 93.83% at 24 hours fermentation. The highest average value of output capacity 358.77 kg/h at 72 hours and lowest of 202.29 kg/h at 24 hours fermentation time. These results showed that the stripper will be able to handle up to two tons of oil palm fruit bunches in a day at 72 hours fermentation; thus, making it affordable for the small and medium scale oil palm fruit processing industries in Nigeria at a low cost of purchase and maintenance.
