Product details and specs

With effort-saving self-propulsion and an expansive 51cm cutting-width, the range-topping Alpina AL5 51 SHQ is a great choice for larger gardens and will power its way up slopes and across rough ground!
At its core is a premium-grade 166cc Honda four-stroke engine that exceeds EU emission requirements; and which benefits from fuel-saving and noise-reducing OHV technology.
Offering four cutting-modes – collection; mulching; side/rear-discharge – the AL5 51 SHQ is supremely flexible in use and can be configured to achieve superb results on a wide variety of grass-types.
A comfortable and easy to operate as it is fast-working and versatile, the AL5 51 SHQ benefits from a two-step quick-adjust handlebar with an ergonomic hand-grip; and hassle-free cutting-height adjustment by way of only one lever.
Thanks to its front grass-comb, which lifts the grass prior to contact with the blade, the AL5 51 SHQ produces a beautifully neat and even finish.
Sizeable 280mm drive-wheels provide gentle traction on delicate lawn surfaces; while a practical carry handle means you’ll have no problems lifting the mower in and out of the shed.
The capacious 60-litre grassbag on the AL5 51 SHQ has been equipped with a ‘collector full’ warning indicator that makes it unlikely you’ll exceed capacity and block the discharge chute.
Durability-features on this model include a robust steel chassis, a protective front-bumper and ball-bearing wheel mounts.
