    Overview

    More Power and More Width for Larger Lawns When your lawn gets bigger, your mower needs to keep up. The Hyundai HYM20200SPX steps up with a 20" / 51cm cutting width and a 196cc engine producing 5.5hp. That's nearly 50% more power than the 139cc models, giving you the muscle to handle thicker grass, longer growth, and larger areas without bogging down. This is a self-propelled machine built for medium to large gardens. The wider deck covers more ground per pass. The bigger engine maintains blade speed even when conditions get tough. And the 60L collection bag means you're not stopping to empty every few minutes. Key Benefits Power That Doesn't Falter The 196cc engine delivers 5.5hp / 4.1kW. That extra power matters when the grass has grown longer than planned, or when you're tackling thicker lawn varieties. The blade speed stays consistent, giving a cleaner cut. Cover Ground Faster A 20" / 51cm cutting width reduces the number of passes needed. On a 1,000m² lawn, you'll make noticeably faster progress compared to an 18" mower. Handle It All Mulch, bag, discharge from the side, or discharge from the rear. Four cutting options let you respond to what the lawn needs rather than forcing one approach year-round. Who Is This For? This mower is ideal for: Owners of medium to large gardens (approximately 750m² to 1,500m²) Those who regularly face overgrown or thick grass Gardeners wanting more power than a 139cc engine offers Users who need a capable all-round machine This mower is NOT ideal for: Small lawns where a 20" deck is harder to manoeuvre Those who prefer electric start — see the HYM20200SPEX Very large lawns over 1,500m² — consider the 22" HYM22200SPEX
