Our verdict
The mower that paved the way for the SP46. Older but still capable and the used supply is huge — typically £20–40 cheaper than an SP46 in equivalent condition. If you find a clean one, snap it up.

- Same Stiga engine family as the SP46

Buying second-hand
£70–140 is the realistic used range. Massive Marketplace volume — never overpay. Test self-propel under load. Drive cable replacement is £15 DIY. Avoid any with melted plastic around the muffler — sign of dry-running and overheating.
