Ryobi OLT1832 Review – UK Tested

This one came home with nothing in the box but the trimmer itself, no battery, no charger, and I only bought it because I’d already got a drawer full of Ryobi packs from a drill I picked up years ago and never quite got round to replacing. It sat in that drawer for longer than it should have too, the line trimmer equivalent of a tool you buy with good intentions and then leave wrapped until the grass finally embarrasses you into action.

It’s an 18V cordless trimmer on Ryobi’s ONE+ platform, weighing 2.3kg, and the cutting width adjusts between 25cm and 30cm depending on which way round you fit the line cutter blade, narrower for a bit more battery life, wider when you just want the job done quicker.

Overview and first impressions

The head rotates through a full 180 degrees with three separate pivot positions, which sounds like a spec sheet number until you’re the one bent half over trying to get under a bench, and then it stops being a number and starts being the only reason your back doesn’t complain. Auto feed handles the line on its own as it wears down, no bumping, no faff, just less line wasted than the trimmers that feed a bit more out every time you so much as twitch the trigger.

One thing that caught me out the first time: the line keeps spinning for a second or two after you let go of the trigger, which sounds obvious written down but is easy to forget mid-job. Bystanders, kids and pets need to stay a proper 15 metres back while it’s running too, further than most people would naturally assume.

Specifications and scores

There’s an optional heavy duty blade disc sold separately too, for the days line alone won’t cut it against properly established weeds, swapped in instead of the standard nylon head when the job calls for something with more bite.

How it performed in our tests

I tried to bog the motor down on purpose, stuck it straight into a patch of long grass that hadn’t been touched all spring and just held it there. It slowed for a second, found its footing, and kept going rather than stalling out the way I half expected it to. The single line did feel slower against thicker stuff than a double string head would have managed, more passes needed to get through the same patch, but it never once gave up on me.

Switching the blade attachment in for the taller weeds round the base of a fence post made short work of the stalks that line alone had been struggling with, and going back to the standard nylon head afterwards for the finer bits along an edge gave a tidy finish without much thought needed either way.

It’s not a quiet tool by any measure, closer to a blender running flat out than anything gentler, and more than half an hour at that level is enough to do some damage if you skip the ear defenders. I don’t, not after the first time I forgot and noticed my ears ringing afterwards.

Worth knowing before you reach for it on the wrong job: this is built to cut with the line roughly flat to the ground when trimming, and roughly upright when edging, never angled to take on a hedge or a bush. It’ll happily nibble at a low shrub if you let it wander, but that’s not what the cutting plane is designed for and it shows in how clumsy the result looks.

Battery system and runtime

Going without a battery at all is the thing that makes this trimmer genuinely different from everything else I’ve used in this category. Every other one came as a proper kit, battery and charger included, ready to go straight out of the box. This one assumes you’ve already got the battery platform sorted, and if you have, it’s the cheapest way into a perfectly capable trimmer there is.

ONE+ batteries run from small, light packs right up to the bigger 5.0Ah ones, and whichever you’ve already got slots straight in without a second thought. That’s the real saving here, not the trimmer itself being cheap, but never needing to buy another charger or another battery ever again once the first one’s bought.

Performance and limitations

What this gets right is honesty about what it is. A lightweight, capable trimmer for a garden that doesn’t need a brush cutter, sold at a price that only makes sense once you’re already invested in the platform, and surprisingly strong once it’s moving.

The build itself feels a touch flimsy in places, the cutting width on the small side next to some rivals, and the single line setup is the slower option if speed through thick growth matters more to you than anything else. None of that stopped it finishing every job I gave it.

Final verdict

This earns its place specifically for the people it’s built for, not everyone. Already on the ONE+ platform, wanting a light, capable trimmer without buying yet another battery and charger, and this is hard to beat on that basis alone.

Starting from scratch changes the maths completely, since a bare tool plus a separate battery and charger rarely works out cheaper than a proper kit elsewhere. That’s not a flaw in the trimmer, just the honest reality of how it’s sold.

Match it to the right person and it does exactly what it promises, no more, no less.
