Upgrade or replace your existing power unit with this high-performance 15HP 420cc Loncin Petrol Engine (Model: TP420FENG). Suitable for a wide range of heavy-duty garden machinery, including petrol wood chippers, shredders, mulchers, and stump grinders, it offers a versatile, commercial-grade replacement option for compatible outdoor power equipment.

Loncin 15HP 4-stroke petrol engines have been a trusted, established choice across the UK for over 15 years, delivering exceptional torque, easy pull starting, and long-term operating reliability. Equipped with a standard 25mm straight shaft (approx. 56.75mm output length and 7.15mm keyway), this engine is also well-suited for custom machinery builds and engineering projects such as go-karts, provided mounting footprint and shaft measurements match your setup.

Titan Pro Tech Tip: Engine Setup, Shaft Dimensions & Oil Capacity

Before ordering, always cross-check your existing engine‘s crankshaft drive diameter (25mm), keyway width (7.15mm), and mounting bolt hole centers. Loncin 420cc engines feature a 1.1L oil capacity and require fresh SAE 10W-30 or 15W-40 4-stroke engine oil prior to initial startup. Maintain the multi-stage air filter element regularly when operating in dusty wood chipping or stump grinding environments to safeguard cylinder bore longevity.

Featuring a durable single-cylinder air-cooled OHV design, heavy-duty recoil starter, 6.5L fuel tank, and high-efficiency cyclone-type filtration assembly, this complete engine unit ensures reliable heavy-load operation.
