Description
The PD400FQ is the smallest engine in the PdPro own-brand range; a 4hp OHV horizontal crankshaft unit with automatic decompression for easy starting and oil alert for long-term protection. The 3/4″ crankshaft suits lighter machinery and equipment builds where a compact, low-cost petrol engine is the practical choice: small pressure washers, pumps, light construction equipment and agricultural machinery. For dealers who need an entry-level engine option without the overhead of a premium brand, this fills that gap cleanly.

Why stock this?
The PD400FQ sits at the entry point of the PdPro own-brand range. At 4hp with a 3/4″ shaft it covers lighter applications that the larger units would be overkill for. For dealers building out a complete own-brand engine offering, this is the unit that serves customers who need a basic, reliable petrol engine at the lowest price point in the range.
