Our verdict
The mower people who care about their lawn buy when they can afford to buy once. Hayter Harrier with a Honda engine is genuinely a forever machine — 30-year-old Harriers still come up serviced. The 56AD is the largest, most pro-grade Harrier; overkill for under 1500m² but transcendent for over.

Buying second-hand
£600–900 used. Honda engine hours matter — under 200 is excellent. Hayter rear roller and AD drive linkage are the wear points; both serviceable at any Hayter dealer. Original Hayter spec sticker on the deck adds £80 to fair value. Anything with welded chassis repairs, walk away.
