AS 21 2T ES Allmäher Mower – Slope-Safe

AS 21 2T ES is a specialist Allmäher built for steep slopes, angled ground and awkward terrain where standard petrol mowers struggle or fail. Its AS-Motor 2-stroke engine delivers reliable torque at any angle and keeps full lubrication even on 45° banks, making it one of the safest compact machines for hillside work.

Users who need a light, agile mower for orchard banks, vineyard rows, ditch edges or terraced ground will find this model far easier to control than heavier cutters. The swivel front wheel locks diagonally for stable cross-slope mowing, and the high-positioned snorkel filter helps the engine breathe clean air even in dusty summer conditions. Suffolk Mowers supplies the AS 21 2T ES with setup guidance, slope safety advice and a full 2-year AS-Motor warranty.

What AS 21 2T ES Is Built For

AS 21 2T ES is designed for ground that ordinary petrol mowers simply can’t handle. Steep banks, orchard slopes, ditch edges and terraced plots are where this machine proves its value. The 2-stroke engine keeps its lubrication at any angle, giving you reliable power and slope safety without the risk of seizure or oil starvation that affects 4-stroke machines on inclines.

Cutting Performance

Strong 2-stroke torque keeps the blade moving through grass up to around 90 cm, even on uneven or angled terrain. The wing blade runs on friction discs with a third crankshaft bearing to protect the engine from hidden stones. Cutting height adjusts between 55–80 mm using simple front and rear settings suited to long-grass control rather than lawn finish.

Handling and Slope Control

Light, compact and responsive, AS 21 2T ES is one of the easiest slope-capable petrol machines to guide across awkward angles. The caster front wheel pivots freely for tight manoeuvring and can be locked diagonally when working across a bank, improving stability. Rear-wheel drive gives steady forward pull without fighting the terrain, while the 54 kg weight keeps the machine manageable on rough ground.

Position in the AS-Motor Range

• More capable on steep slopes than any 4-stroke Allmäher thanks to position-free lubrication.
• Lighter and more agile than the AS 26 2T, making it a strong choice for tight, angled spaces.
• Less planted than the AS 63 2T but easier to transport and store, and more affordable.
• A clear step up from consumer slope mowers that lack torque, lubrication safety and engine protection.

Practical Ownership

Reliable cold starts come from the EasyStart system, which reduces the pull effort. The snorkel filter stays cleaner for longer when working on dusty orchard banks or sun-dried slopes. Basic maintenance is straightforward, with only 2-stroke oil mixing required. A 5-litre tank offers solid working time between refills without making the machine heavy.

Useful Accessories

• Twin wheels – improves traction and balance on cross-slope work.
• Climbing aid – extra grip for steep ascents.
• Hand guards – useful in bramble or thorny areas.
• Tilt meter – helps operators judge slope angle safely.
• Special blade – suited to sandy or abrasive soil.

Who This Model Suits

Ideal for users who work on genuine slopes and banked areas where a 4-stroke mower won’t survive. Orchard owners, small vineyard operators, smallholders with terraced land and gardeners responsible for steep boundary banks get the most from this model. It also suits contractors working on sites where access is limited and heavier machines are impractical. If strimming steep banks is becoming unsafe or too time-consuming, AS 21 2T ES offers a controlled, faster and safer alternative.
