The spec-sheet read
Our analysis of the sourced spec sheet — positioning and trade-offs, not a hands-on review. We don't score mowers we haven't tested.
The lightest, cheapest petrol push option here — a 79 cc, 19 kg mower for very small lawns.
The HYM400P is the entry point to petrol in this catalogue: the smallest engine (79 cc) and one of the lightest bodies (19 kg), with a 40 cm steel deck, a 40 L bag, six cutting heights and a simple hand-push action. It is aimed squarely at very small lawns and first-time petrol buyers who want minimal weight and don't need self-propulsion.
Despite the budget positioning it carries a 3-year domestic warranty, which is strong for an entry push mower. If your lawn is small and flat and you want the cheapest, lightest way into petrol, it fits; anything larger or longer is better served by a wider self-propelled deck.
Verification note: Marked unverified: the specs come from an established retailer listing (The Green Reaper), but Hyundai's own product URL returned a 404 when we tried to capture it. We will mark it verified once the manufacturer page is located and the figures confirmed.
