Our verdict
The HYM510SPE undercuts Mountfield by £30-50 and adds electric start, which is the genuine USP. The Hyundai engine is competent if not heroic — expect 7-10 years of reliable use rather than the 15-20 a Honda HRX delivers. A solid value buy if you don't care about stripes.

Buying second-hand
£160-260 used. Always check the electric-start battery (small sealed Ah pack under a side panel). A dead battery doesn't kill the mower (recoil still works) but a working button is worth £30. The IC196 takes the same NGK plug and air filter as the Briggs 750EX — spares are cheap and on shelf at any Hyundai or generic small-engine dealer.
