The AS 21 E-Allmäher brings the classic AS 21 layout into the battery era, using the 56-volt AS-Motor Electric system to deliver petrol-like power without the fumes, noise or upkeep. With a 51 cm deck, rear-wheel drive and a steerable front wheel, it handles orchard strips, paddock edges and awkward shapes with far more control than a four-wheel mower.
It suits owners who want a light rough-cut mower for grass up to 60 cm without moving to a heavier petrol Allmäher. The electric drive gives smooth torque, and the option to run a 28 Ah back battery means long sessions are possible without fuss. If you’re already using EGO tools, the shared battery ecosystem makes it an even easier fit.
Working Capability and Real-World Use
The AS 21 E-Allmäher is built for lighter rough cutting where noise, weight and manoeuvrability matter as much as power. Its 51 cm deck and AS-Motor Electric drive give it enough punch for grass up to about 60 cm, which covers orchard strips, paddock edges, paths and rougher areas that a domestic mower simply won’t cope with. It’s not a flail or a heavy Allmäher, but for seasonal meadow-type growth and orchard grass it feels quick, tidy and controlled.
Where It Fits in the AS-Motor Range
AS 21 E sits below the petrol AS 62, 63 and 65 models in outright capacity, but above domestic cordless machines in build and cutting strength. Compared with the petrol AS 21 versions it delivers similar working behaviour without fuel, fumes or engine servicing. If your work is mainly moderate-height grass with trees, posts and tight corners, this is a neater fit than the heavier, slope-focused Allmähers that are built for 1 m plus growth and serious banks.
Who the AS 21 E-Allmäher Suits
- Private owners with meadow orchards, paddock edges or rough lawns that keep outgrowing domestic mowers.
- Holiday parks, campsites and leisure sites where quieter operation is essential.
- Equestrian yards that want to keep small rough areas in check without running a tractor out for every job.
- Grounds teams and contractors who already use EGO tools and want a battery rough cutter on the same ecosystem.
It appeals to users who value light handling, low noise and clean running over brute-force performance in very heavy growth.
Strengths That Matter Day to Day
- The 3-wheel layout makes it easy to swing around trees, posts, fences and play equipment.
- The steerable front wheel can be locked, so the mower tracks straight on gentle slopes instead of drifting.
- The AS-Motor Electric drive delivers smooth, instant torque with no warm-up or fuelling issues.
- The blade protection system (third bearing and friction discs) reduces the risk of motor damage if you hit hidden objects.
- The comfort handlebar adjusts quickly for different users, keeping control solid without fighting the machine.
- The whole unit folds down to fit into a van or estate car, which is a real plus for mobile work.
Operational Realities
This mower is designed for grass, not for bramble or heavy scrub. In growth up to about 60 cm it stays composed and produces a decent rough-cut finish, but when the material gets taller, wetter or more tangled than that it will slow and you’ll be working at the limit of what the deck is meant to handle. On slight slopes the locked front wheel and rear drive feel reassuring, but if your main workload is banking or steep ditches the AS 63 or 65 slope machines are the safer option.
Runtime depends on battery choice. With two 10 Ah packs you have enough energy for typical orchard or yard work; adding the 28 Ah back battery changes it into a full-session machine, but you still need to be realistic about how much heavy going you tackle in one hit. Compared with petrol you lose refuelling speed but gain quieter running, less vibration and much lower day-to-day maintenance.
Accessories Worth Considering
- Rear wheel brake: helps hold speed and position on gentle slopes or when working near obstacles.
- Plastic hand guards: useful if you have thorny growth or scrubby edges where branches catch your hands.
- Special blade: a better choice for sandy or abrasive soils where standard blades wear fast.
- Hour meter: handy for tracking real use, especially if the machine is part of a small fleet.
- Tilt meter: gives a quick, visual check of slope angle if you do work on marginal ground.
If your ground is mainly moderate-height grass with obstacles, the AS 21 E-Allmäher hits a useful balance: light, quiet and capable enough to handle jobs that overwhelm domestic cordless mowers, without dragging you into the weight and complexity of a full petrol Allmäher.
