2. The Mechanics of Submerged Propulsion: How Our Boat Tractor Gearbox Works<\/h2>\n

Unlike standard dry-field tractors, the Boat Tractor<\/b> relies on a transmission that acts more like a marine gearbox than a land-based one. Located at the central hull and the wheel hubs, the gearbox must convert the engine’s high RPM into low-speed, high-thrust motion to churn through mud. Our design utilizes a Spiral Bevel configuration<\/b> to provide a 98.5% efficiency rate, reducing fuel consumption for large-scale rice farmers.<\/p>\n
