If you already run a compatible BLACK+DECKER strimmer, the BLACK+DECKER CM100 3-in-1 String Trimmer Deck is the add-on that turns it into a small lawn mower in seconds. Here’s the thing — instead of wrestling a handheld trimmer across a patch of grass, you slot it into this wheeled mower base and suddenly you’ve got steady, level cutting that doesn’t chew your arms up halfway through the job.

The design is simple but clever. The click-in mounting system locks your trimmer into position so the line cuts at a consistent height, and the adjustable wheel setup lets you choose between roughly 40–60mm cutting height. In practice, that means cleaner results on small lawns, slopes, and awkward garden sections where a full mower just feels like overkill — or won’t even fit.

Key Features:

• Click-In Tool Mount - Lets you attach a compatible strimmer fast so switching between trimming and mowing takes seconds.
• Adjustable Cutting Height - Wheel height settings help you keep grass even instead of scalping patches.
• Lightweight Wheeled Base - Makes pushing easier and reduces arm fatigue compared with freehand trimming.
• Compact Storage Design - Takes up far less shed space than a dedicated mower.
• Small-Area Optimised Platform - Works especially well on tight lawns, uneven ground, and sloped gardens.

Applications

This setup shines in small garden maintenance, especially where dragging out a full mower just isn’t worth the hassle. It’s also handy for uneven lawns and slopes where handheld trimming normally leaves wavy results. And if you maintain rental properties, holiday homes, or compact residential yards, the convert-your-trimmer system saves hauling multiple machines to site.

Why Choose This Model

What really stands out is how practical this thing is for real-world use. The tool-conversion approach means you’re stretching the value of gear you already own instead of buying another motorized machine. And because the push-style mowing control keeps the cutting line at a fixed level, you get a noticeably tidier finish compared with freehand trimming — that matters a lot when customers actually care how their lawn looks.

Technical Specifications Explained

• Cutting Width ~30cm - Gives decent coverage for small lawns while still fitting into narrow spaces.
• Height Range 40–60mm - Lets you choose between a tighter finish or slightly longer grass for rougher ground.
• Weight About 2.5–2.7kg - Light enough to carry and hang up without it becoming another heavy garden tool.
• Manual Push Operation - No motor inside the deck, so all drive comes from your existing trimmer.
• Multi-Model Compatibility - Designed to fit several BLACK+DECKER strimmer models, reducing the need for dedicated equipment.

Who Should Buy This

If you’re a homeowner with a compact lawn, a landlord handling quick property tidy-ups, or a tradesperson who wants a space-saving mowing option for light jobs, this makes a lot of sense. It’s not trying to replace a full petrol mower — and honestly, it shouldn’t. That’s not the point.

The bottom line is simple: if you already own a compatible BLACK+DECKER trimmer and you’re tired of patchy handheld cuts, this deck turns that same tool into a controlled push mower. Less strain. Cleaner finish. Faster small-area work. And sometimes that’s exactly what the job calls for.
