We've broken down all four core models - plus a few close relatives worth knowing about - with links through to our full in-depth reviews of each.

    17" / 43cm Self-Propelled Petrol Lawnmower — HYM17150SPX

    £239.99 £215.99 SAVE 10%

    The smallest mower in the Black Edition line-up, but it's still self-propelled — a genuine step up from hand-push entry models. A 139cc engine (3.7hp) drives the rear wheels, the 40L bag keeps emptying trips down, and you get all four cutting modes: mulch, bag, side discharge, and rear discharge. Best suited to lawns up to around 750m² where you want drive assistance without the bulk of a wider deck.

    Balanced All-Rounder · 46cm Deck

    18" / 46cm Self-Propelled Petrol Lawnmower — HYM18150SPX

    £289.99 £259.99 SAVE 10%

    Same proven 139cc engine as the 43cm model, but a wider 46cm deck and a noticeably larger 60L bag — 50% more capacity, so fewer trips to the compost heap. It's the model we'd point most medium-garden owners toward: enough width to make real progress on 500–1,000m² lawns, without tipping into "this is hard to store" territory.

    More Power · 51cm Deck

    20" / 51cm Self-Propelled Petrol Lawnmower — HYM20200SPX

    £329.99 £294.99 SAVE 10%

    This is where the range steps up to a 196cc engine — nearly 50% more power than the 139cc models below it. That extra muscle matters once grass gets thick or overgrown, keeping blade speed up rather than bogging down. The 60L bag and 7-position height adjuster (25–75mm) carry over, but the bigger engine and wider 51cm deck make this the pick for medium-to-large gardens (roughly 750–1,500m²).

    Flagship · 56cm Deck · Electric Start

    22" / 56cm Self-Propelled Petrol Lawnmower, Electric Start — HYM22200SPEX

    £400.00 £359.99 SAVE 10%

    The widest deck in the range, paired with electric start — press a button rather than pull a cord. The same 196cc / 5.5hp engine as the 51cm model drives a 56cm cutting width, roughly 10% more coverage per pass, and the largest collection bag in the line-up at 70L. Built for large gardens (1,000–2,000m²) where minimising mowing time matters. It's not the easiest mower to manoeuvre through narrow gates, so check access before sizing up.

    Also Worth a Look in the Wider Range

    Not on this seasonal offer, but closely related to the four models above — worth knowing about if none of them quite fits.

    Budget Hand-Push · 40cm
    HYM16130PX

    A lighter, simpler hand-push 139cc mower for small lawns where self-propelled drive isn't needed. The natural step below the 43cm model.

    46cm With Electric Start
    HYM18150SPEX

    The HYM18150SPX's sibling, with push-button electric start added to the same 46cm deck and 139cc engine. Worth the upgrade if cold starts bother you.

    51cm Zero-Turn · Electric Start
    HYM20200SPEZX

    Same 51cm deck and 196cc engine as the HYM20200SPX, but with electric start and zero-turn front wheels for tighter manoeuvring around borders and trees.

    Heavy-Duty Pro Build · 53cm
    HYM530SPPRO

    A reinforced 1.8mm steel deck, HD gearbox, and a built-in raking function for matted grass. For anyone who wants a mower that shrugs off heavy seasonal use.

    Quick Sizing Guide

    • Up to 750m²: HYM17150SPX (43cm) is enough mower without unnecessary bulk.
    • 500m² – 1,000m²: HYM18150SPX (46cm) balances coverage and manoeuvrability.
    • 750m² – 1,500m²: HYM20200SPX (51cm) adds the 196cc engine for thicker grass.
    • 1,000m² – 2,000m²: HYM22200SPEX (56cm, electric start) for maximum coverage per pass.
    • Narrow gates or tight access? Stick to 43cm or 46cm regardless of lawn size.
