Allett Cambridge 43 Battery Cordless Cylinder Mower

👉 Prefer it ready to mow? Get the Cambridge 43 Complete Bundle — mower, battery & charger for $4,999.99, saving $49.98 versus buying separately. Everything in one box, nothing to source.

The Allett Cambridge 43 is the battery equivalent of the Kensington 17B: a 17″ self-propelled cordless cylinder mower that gives a medium-to-large lawn a clean, close, striped cut — quietly, on 40V battery, with the full Rapid Change cartridge system behind it. It replaced the Liberty 43 in Spring 2024, redesigned from Liberty owner feedback for better balance and easier cartridge changes.

Why you'll love it

• A true cylinder finish — a 6-blade cutting cylinder at 78 clips per metre for the close, crisp stripe a rotary can't match.
• Quiet, cordless power — 40V lithium-ion, push-button start, no petrol and no cable to drag.
• One machine, a whole lawn-care system — takes every RC43 Rapid Change cartridge: scarify, verticut, dethatch, aerate, brush.
• Rapid cartridge change — no belts or side cover to remove; one screw each side of the cylinder and you're swapped over.
• Stepless height of cut — dial anywhere from 6 mm to 32 mm, shown in millimetres.
• Made by Allett — the cylinder-mower craft trusted on professional sports turf, brought to your lawn.

Is the Cambridge 43 right for you?

• Choose the Cambridge 43 if you have a medium-to-large lawn (up to ~450 m²) and want the quiet of battery plus the full cartridge cultivation system.
• Consider the Cambridge 35 instead if your lawn is smaller — it's the 14″ model in the same battery range.
• Consider the Kensington 17 instead if you'd rather have petrol power for the same 17″ cut and cartridge system.

What you need to start

This listing is the mower only. The Cambridge 43 runs on the 40V Greenworks battery platform, so to mow you'll also add a compatible 40V Greenworks battery and a charger (they interchange with other Greenworks 40V tools). Add all three before checkout so it arrives ready to run — or skip the guesswork with the Complete Bundle, which includes them for $4,999.99.

Complete your setup

• 40V Greenworks battery — required to run.
• Greenworks charger — required to run.

• QC2RC conversion kit — only if you're bringing older QC17 cartridges across from a previous machine (one kit per cartridge).
• Reel Grinding — By Mail — send your cutting cylinder in for a factory-standard regrind.

FAQ

• Is it powerful enough for a bigger lawn? Yes — it's built for medium-to-large lawns up to ~450 m², with about 30–40 minutes of mowing per charge.
• Which battery do I need? A 40V Greenworks battery and charger (add both above). We can help if you're unsure.
• Will my old QC cartridges fit? Yes, with a QC2RC conversion kit — one per cartridge. If you're starting fresh, buy RC43 cartridges directly.
• How does it compare to the Kensington 17? Same 17″ cut and cartridge system — the Cambridge 43 is the quiet battery version, the Kensington 17 is petrol.
