Toro Greensmaster® e1021 Electric Walk Behind Greens Mower

Model: 04835
Toro

The Toro Greensmaster e1021 is the 53.3 cm (21″) fixed-head electric walk-behind in the Electric Series. A 51.4 V lithium-ion pack (1.35 kWh) covers about 3,250 m² (35,000 sq ft) on a charge. The LCD shows battery state, hours and diagnostics while you mow.

Same telescoping loop handle and modular gear-drive layout as the petrol 1021, but with a brushless motor and an off-board 650 W charger (about four hours empty to full). Fit an 8, 11 or 14-blade EdgeSeries DPA reel. Standard backlapping. Dual-position traction drum for contour following or extra forward weight at higher heights of cut.

No exhaust at the machine, so you can mow early without a petrol note across the first tee.

Frequently Asked Questions

What’s the difference between the Greensmaster e1021, e1026 and eFlex 1021?

All three are lithium-ion walk-behind greens mowers in Toro’s Electric Series, with the same 51.4 V pack (1.35 kWh), telescoping handle and LCD. The difference is cutting width and whether the cutting unit is fixed or Flex.

  • Greensmaster e1021 (04835): 53.3 cm (21″) fixed-head. About 3,250 m? (35,000 sq ft) per charge. 8, 11 or 14-blade DPA reels.
  • Greensmaster eFlex 1021 (04865): 53.3 cm (21″) Flex suspension, so the cutting unit follows undulations. About 3,250 m? per charge. 11 or 14-blade Flex reels, tool-free cutting unit change.
  • Greensmaster e1026 (04845): 66 cm (26″) fixed-head. About 4,087 m? (44,000 sq ft) per charge. 8 or 11-blade DPA reels.

How can mulching improve my lawn’s soil and reduce water usage?

Mulched grass clippings improve soil structure by adding organic matter, which enhances the soil’s water absorption by up to 12%. This means less water is needed to keep your lawn healthy, making mulching a great choice in areas with water restrictions. Toro mowers with Vortex Technology increase airflow to the deck, ensuring clippings decompose quickly and effectively.

How does mulching help control weeds?

Mulching with Toro’s Recycler® Technology creates a natural barrier that helps prevent weed seeds from reaching the soil, reducing the chances of weed growth. Regular mulching also promotes thicker, healthier grass, which can outcompete weeds, further minimizing their spread​.

NOTE: If your lawn already has large sections of weeds, mulching could inadvertently spread weed seeds. In such cases, it’s better to bag the clippings to avoid spreading those weeds to other areas. Once the weeds are under control, you can return to mulching to promote a healthier lawn​.

What are the benefits of using a mulching mower, and how does it improve lawn health?

Mulching mowers, like those from Toro, help recycle grass clippings back into your lawn, providing nutrients and reducing the need for fertilizer. Studies show that mulched clippings can reduce nitrogen fertilizer usage by up to 50% since the nitrogen from the clippings is slowly released back into the soil. Toro’s Recycler® Technology finely chops the grass, creating “Lawn Vitamins” that naturally enrich your lawn’s soil​.
