Einhell GC-PM 46/5 S Petrol Self-Propelled Lawn Mower
Product description
What it is and what it solves
The Einhell GC-PM 46/5 S is a petrol-powered, self-propelled lawn mower designed for larger gardens, with a 46 cm cutting width and a robust 4-stroke engine. It aims to take the effort out of mowing sloped or uneven terrain by providing rear-wheel drive, while offering a straightforward way to cut, mulch and collect grass, so you can keep a tidy lawn without repeating sessions.
How it performs in practical terms

On the practical side, you get nine central cutting-height settings (25 mm to 80 mm) to tailor the finish to your lawn’s needs. The self-propelled drive is a real help when you’re pushing uphill or across long stretches, reducing strain and improving consistency. A mulch option exists, described as shredding leaves to a tenth of their volume, which can be useful if you want to recycle clippings into a mulch layer or compost.
What stands out in use
A clearly visible fill level on the grass box and a relatively large bag capacity help you plan emptying breaks without constant stops. The viewing window keeps you aware of when the bag is nearing full. The guide bar is height-adjustable to match the operator’s height, which contributes to more comfortable mowing sessions. Space-saving storage is possible thanks to a foldable handle, which is a practical touch if you’re short on shed space.



What may hold it back
As a petrol mower, ongoing costs include fuel and maintenance of a four-stroke engine. The 2 kW-rated power and 2,900 rpm idle suggest solid performance for medium to large lawns, but real-world results depend on grass conditions and bag capacity. There is a trade-off between power and weight, self-propelled mowers are convenient, yet heavier to move when not engaged. The exact collection-bag capacity is listed inconsistently in the source data (50 L versus 65 L or 40 L in different lines), so you may want to confirm the precise bag size before purchase.
Who it’s for

If you have a sizeable garden up to roughly 1400 m² and want a mower that reduces effort on slopes, the GC-PM 46/5 S could suit you. It’s also a sensible option if you prefer a petrol-powered machine that doesn’t rely on a battery and can cover large areas in fewer passes.
Who it’s not for
If your lawn is very small or you prioritise ultra-quiet operation and minimal maintenance, a corded or cordless model might be preferable. Those who rarely mow and want a lighter device may find a petrol mower too heavy or complex for occasional use.



When it makes sense to buy
Consider this mower if you value: reliable propulsion to tackle slopes, a respectable cutting-width for faster coverage, adjustable height for different grass types, and a straightforward approach to disposal with a visible fill indicator. It also makes sense if you already use petrol tools and want to keep a consistent engine type across your garden equipment.
What to review before buying

- Confirm the exact grass-box capacity from the retailer to avoid surprises.
- Check the availability of spare parts and routine maintenance requirements for the 4-stroke engine.
- Ensure a practical storage plan for the mower handle when folded.
- Compare cutting-height range (25–80 mm) with your lawn’s preferred finish to ensure it matches your needs.
How it compares to common alternatives
For larger gardens, a self-propelled petrol mower like this sits between basic push mowers and more premium models with additional features. If you want to reduce effort on slopes, the rear-wheel drive is a clear advantage over push-only designs. If you prefer quiet operation or very low maintenance, a cordless or push model might be more suitable, though they may require more frequent recharging or more passes to complete large areas.



Practical use example
Imagine a weekend mowing session on a gently sloping lawn. You set a mid-range cutting height, engage the self-propulsion, and glide along—grass box filling gradually, you glance at the window to know when to stop and empty. On damp mornings, you might notice the mulch option helps manage leaves without gathering a lot of material at once, keeping the pace steady.
Final decision
Is it worth it?
Worth considering if you prioritise ease of use on larger lawns and want a petrol mower with self-propulsion, solid cutting width, and adjustable height. If you’re after quiet operation, lighter weight, or minimal maintenance, you may want to explore alternatives.
