A multifunctional rice claw created by the brothers Nguyen Huu Nhat and Nguyen Huu Thong, in the village of Tan Sinh Tay, Cam Lam commune, Khanh Hoa province, now loads up to 400 bags per day during harvest, reducing manual labor in uneven and muddy rice fields.
Multifunctional rice claw changes routine in the rice fields of Tan Sinh Tay
During the recent harvest season, the mobile loading and unloading system for agricultural products operated continuously in the rice fields of the village of Tan Sinh Tay. The machine lifts, lowers, rotates, and places rice bags on trailers attached to the tractor.
The equipment was created to tackle one of the heaviest stages of the harvest: loading and transporting the bags after the rice is removed from the field.

Former Brazilian reality star Caio Afiune shares how a farming mistake with 800,000 cabbage plants led to a $300,000 debt, highlighting the importance of rural management over just high production.
Previously, this task relied on workers manually carrying the products to the transport points.
The solution was co-invented and technically improved by Nguyen Huu Nhat, born in 1996 and graduated in surveying, and by his brother, Nguyen Huu Thong, a local mechanical engineer. The idea arose from the practical needs of their own family.
Hydraulic system is installed on a 61-horsepower tractor
The multifunctional rice claw was designed to be permanently installed on the hydraulic lifting system located at the rear of a 61-horsepower tractor, coupled to a trailer.
The set works with a rotating crane and a flexible mechanical claw controlled by hydraulic pressure. In practice, workers position the claws to hold the rice bags in the field.
After that, the crane system lifts the bags, rotates horizontally, and stacks the material in organized layers on the trailer.
The operation requires coordination between the tractor operator and the worker who follows the movement in the field.
According to the provided material, the machine was seen operating in complex terrains after the harvest, including uneven and muddy areas, common in rice fields during this period.
Each hectare may require more than 130 bags loaded by hand
The brothers pointed out that the greatest pressure on farmers occurs after the harvest, at the time of loading and transporting the agricultural products.
In high-yield rice areas, each hectare may require the manual loading of more than 130 bags.
This work demands great physical endurance. Workers need to stack heavy rice bags above head height, often under intense heat, making the stage tiring and time-consuming.
Another problem mentioned is the scarcity and rising cost of local seasonal labor. This difficulty causes frequent interruptions in the transportation of rice from the fields to the drying locations.
With the machine, farmers can better control the timing of collection and transport directly to the receiving point. The reported capacity reaches up to 400 rice bags per day.
Model uses available materials and parts from old vehicles
According to Tran Danh, head of the Tan Sinh Tay village, the model created by Thong and Nhat is an innovation of great practical importance for the region. He highlighted the brothers’ technical training and the professional experience used in the development.
The inventors independently researched, took advantage of easily available materials, and collected components from old vehicles to minimize manufacturing costs.
The core of the initiative was to design a lifting mechanism directly connected to the family’s existing tractor. The system was also synchronized with the vehicle’s original hydraulic mechanism.
Only specialized technical equipment needed to install and complete the project had to be acquired from the city hall, according to the information provided.
Tran Danh assessed that the device is effective because it frees farmers from manually loading heavy bags.
For him, the benefit is even more important for older agricultural workers, who previously had to perform this task in previous years.
The village chief also stated that the model has the potential to be replicated among families in Tan Sinh Tay and neighboring areas, aiming to improve the overall efficiency of the harvest in the region.
