Allett Buffalo 20 Cylinder Mower
The Allett Buffalo 20 is the ultimate all-rounder in the Allett mower range, expertly engineered to deliver a consistent, first-class finish across a variety of grass types and mowing conditions – even when the grass is wet. Whether you're cutting fine ornamental lawns or managing high-traffic turf, the Buffalo 20 performs reliably and efficiently, making it an ideal choice for both commercial and domestic users.
This high-performance mower is perfectly suited for public parks, large private gardens, schools, sports grounds, and prestige lawns where appearance and consistency matter most. Thanks to its wide 51cm (20") cutting width and relatively lightweight design, the Buffalo 20 is not only capable of covering large areas quickly, but it also remains highly manoeuvrable in more intricate spaces.
At the heart of the machine is the proven Honda GX120 petrol engine, delivering 3.5hp of dependable power. This ensures smooth operation and the strength needed for intensive, professional-grade tasks. The fixed 8-blade cutting cylinder (200mm diameter) provides clean, precise cuts with a clip rate of 66 clips per metre, producing a refined finish on both shorter and longer grass varieties.
An adjustable cutting height range from 10mm to 40mm gives operators the flexibility to adapt to changing seasonal conditions or specific lawn requirements. Meanwhile, Allett’s iconic rear roller system ensures strong, clearly defined stripes – a hallmark of professionally maintained turf.
The Buffalo 20 is more than just a powerful mower; it’s a step up in turf care. Compared to the Allett Buckingham, it offers increased cutting width, enhanced drive performance, and a more robust design for heavy-duty use. The 79-litre grass collector allows for efficient mowing with fewer stops to empty clippings, and the mower's anti-vibration handlebar ensures user comfort during prolonged sessions.
Whether you're a groundskeeper, turf care contractor, or an estate manager, the Buffalo 20 is designed to meet your needs with reliability, efficiency, and professional results — every time.

James C. (Devon, UK)
Professional finish even in wet grass
We maintain several local sports pitches and the Buffalo 20 has been a game-changer. It delivers a clean, even cut every time—even in damp conditions. The Honda GX120 engine is reliable and powerful, and the striping is absolutely first-class. This mower gives us consistent, professional results with very little hassle
Liam T. (Perthshire, UK)
Reliable, powerful, and easy to use
As someone who mows several public parks, I needed something powerful but manageable. The Buffalo 20 ticks all the boxes. The anti-vibration handle is a big bonus for longer sessions, and the grassbox is huge—less time spent emptying. It's a tough, smart, professional machine
Tom R. (Yorkshire, UK)
Great cut, smooth operation
The finish is stunning and the mower runs incredibly smoothly. I’d give it five stars if the grassbox had a visual fill indicator, but otherwise, it’s near-perfect. Solid construction and the stripes it leaves behind make our club’s grounds look top-tier
