- Flexible Adaptability and Secure Installation
Mounts securely to the tractor chassis front bracket via four M2.5 screws; the clutch housing connects precisely to the flywheel casing with eight M1.6 screws. Power is output through the flywheel-side pulley, suitable for water pumping, CNC machining, equipment drive, and power generation applications. - CNC Precision Manufacturing
All components are CNC precision-machined for high-accuracy fitment, greatly enhancing operational stability and extending service life. - Efficient Cooling and Lubrication
A large centrifugal cooling flywheel rapidly dissipates heat to prevent overheating. The metal ring piston design with connecting rod oil passage lubrication ensures thorough lubrication of piston and camshaft. Two compression rings and one oil ring on the piston crown prevent oil leakage and gas blow-by during prolonged high-intensity operation. - Classic Ignition and Protection
Features an authentic mechanical impact ignition system for precise, responsive starting. The oil inlet’s primary and secondary filter screens effectively remove impurities, protecting internal components and extending maintenance intervals. - Premium Materials and Detailed Craftsmanship
Large-capacity brass fuel tank with oil level sight glass for convenient monitoring. Copper fuel lines are fiber-brazed for enhanced corrosion resistance and reliability — professional craftsmanship in every detail.
