Remotely controlled, battery powered robotic mower for extreme slopes, tall grass and bush.
2 hours of work per charge on steep slopes or tall grass. Even longer on easy terrain and regularly maintained lawn.
Grator easily climbs slopes up to 70° degrees. It performs equally well uphill, downhill, or horizontally.
Total width 60 cm, length: 105 cm, height 30 cm. Cutting width: 56 cm. Total weight: 60 kg. It fits in a standard car trunk.
Designed to be user-serviceable. All the components are plug-and-play should anything ever need replacing.
Built to outlast its owner, much like the 1960's farm machines that are still in use after decades. No plastic except electrical insulation.
At only 30 cm (12 Inches) height the Grator can go under benches, around vineyard vines, under solar panels, ranch fences, and so on.
The Grator Lowrider is a mulcher, not a traditional mower. Understanding this difference is key to getting the best results out of it. Traditional mowers discharge grass clippings out the side, leaving piles that must be raked up. Mulchers finely shred it into "powder" that is sprinkled around like fertilizer.
With a mulcher, the work is slower, but the result is cleaner—no raking or disposal needed. The extra time you spend on multiple passes is the time you save by not having to dispose of cut grass.
The Grator Lowrider all-wheel-drive remotely controlled brush mower was initially created out of personal necessity by a group of friends who live on hilly terrain. We got tired of mowing slopes with string trimmers in the summer heat. The idea was to relax in the shade and play with the RC mower that can handle any type of grass and terrain.
Living on steep, rugged terrain, we needed a machine that could handle any scenario—something extreme, reliable, and unlike anything on the market. We refused to deal with gasoline engines or constant servicing, so we designed the Grator to be maintenance-free: just clean it with a leaf blower and recharge the battery. No oil changes, no tune-ups, no hassle.
Every mower we'd bought before broke down after a season or two. We wanted something that would last a lifetime—durable enough to survive rolling downhill, simple enough for us to repair with basic tools, and low-profile enough to mow under benches and fences.
Over time, the Grator became our obsession. We set a hard rule: it must outperform any competitor in its class (60 cm (24") / 60 kg) by at least 60%.

Excellent product, excellent service! As an Australian enquiring about this product and because of the fantastic customer service we are now the proud owners of a Grator. My emails with all my questions got answered straight away and the Grator sent within 3days. It works great for what we need it for, I just need to practice my remote skills 🥴😁. If you are procrastinating about getting one well don’t, they are a company I am more than happy to endorse!
Maiden use after waiting 8 months in garage. I had no time to mulch the meadow with fruit trees this year until today. Grass and weed is approximately 1m high. 2-3x pass over and it is done. I did not set the highest position first as recommended - approximately 1/4 of height. Very powerful and now i have time to write this review because battery is charging after 2 hours of mulching in extreme heat. Very happy.
Living on an old farm on the west coast of Norway, I really needed a mower that could help me in the effort to keep steep areas around the house mowed. For years I have used a string trimmer to keep grass and shrubs at bay. This took nearly 2 full days of trimming and raking/disposing - and had to be done 2-3 times a year. So this spring I stumbled over the Grator on Youtube when looking for slope mowers, and it was "love at first sight". I watched all videos of the Grator I could find, and honestly, if the Grator can handle what it is exposed to in the videos (hitting rocks, stumps and branch
Very nice acquisition! The Grator makes gardening a lot easier, certainly working up & down hill or from a distance in case of wasp nests,... All kinds of grasses but also thorns are mowed easily. The company gives excellent service, before and after sale.
Ich besitze den Grator nun seit etwas über einem Jahr und konnte ihn in dieser Zeit wirklich ausgiebig und in jeder Lage testen. Egal ob hohes Gras, dichtes Gestrüpp oder eine flache Wiese – der Grator kommt überall problemlos durch. Die Arbeit geht nicht nur extrem schnell von der Hand, sondern macht dabei auch richtig Spaß. Besonders überzeugt haben mich das moderne, futuristische Design, die hochwertige Verarbeitung und die durchdachten Funktionen, die das Mähen selbst in schwierigen Lagen
Amazing machine. 2 hours a day for three days and I did an exceptional job on very steep terrain full of brush and brambles. Incredible! It eats everything! Great job, thank you Grator !!!
