Why Grator?

Battery duration

2 hours of work per charge on steep slopes or tall grass. Even longer on easy terrain and regularly maintained lawn.

Made for steep slopes

Grator easily climbs slopes up to 70° degrees. It performs equally well uphill, downhill, or horizontally.

Fits in the car trunk

Total width 60 cm, length: 105 cm, height 30 cm. Cutting width: 56 cm. Total weight: 57 kg. It fits in a standard car trunk.

Self-servicing

Designed to be user-serviceable. All the components are plug-and-play should anything ever need replacing.

No planned obsolescence

Built to outlast its owner, much like the 1960's farm machines that are still in use after decades. No plastic except electrical insulation.

Low height of 30 cm

At only 30 cm (12 Inches) height the Grator can go under benches, around vineyard vines, under solar panels, ranch fences, and so on.

What is a Mulcher?

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 cut grass and leave it on the ground. 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.

Traditional Mower

  • Cuts grass and ejects it out the side
  • Open deck design with side discharge
  • Generally faster mowing speed
  • Requires raking and grass removal
  • No natural fertilization

Mulcher (Grator)

  • Finely shreds grass into micro clippings
  • Closed deck traps and re-cuts grass
  • Slower pace for complete shredding
  • No raking needed—zero cleanup
  • Natural fertilization for healthier soil

Our Story

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") / 57 kg) by at least 60%.
