Proton MB-135

Engineering focus: Proton MB-135 transmission

The Proton MB-135 is categorized as a heavy-duty cultivator designed for industrial-grade soil preparation. At its core lies a high-durability gear-driven gearbox. Unlike chain-drive systems, this direct gear transmission ensures maximum torque delivery from the engine to the tiller shaft. This is essential when breaking virgin soil or operating in heavy clay conditions where high resistance is inevitable.

Engine dynamics and operational benefits

The machine is powered by a high-torque air-cooled diesel engine. The choice of diesel power here is intentional: it provides superior "lugging power" at lower RPMs compared to gasoline alternatives. A multi-plate wet clutch system is integrated into the drivetrain to absorb shock loads, protecting the internal gears from damage if the blades strike hidden stones or roots.

• Gearbox Efficiency: The 2+1 speed configuration allows for precise control over the machine's pace. The low gear is specifically tuned for ploughing and harvesting, providing steady progress without operator fatigue.
• PTO Integration: Equipped with a Power Take-Off (PTO) shaft, the unit supports active implements like rotary mowers, significantly increasing its seasonal versatility.
• Weight Distribution: The heavy cast-iron transmission housing serves a dual purpose: it acts as a sturdy structural backbone and provides the necessary down-force for deep soil penetration.

The adjustable handlebar assembly allows the operator to offset the unit to the side, preventing compaction of the freshly tilled soil. Given the modular hitch system, users can easily swap between a variety of standard agricultural attachments, ensuring the Proton MB-135 remains a functional asset throughout the entire crop cycle.
