Model: 04865
Toro

The Toro Greensmaster eFlex 1021 is the 53.3 cm (21″) Flex-suspension electric walk-behind. The cutting unit pivots around the front roller so it follows undulations without scrubbing the surface. That is the difference from the fixed-head e1021.

Same 51.4 V lithium-ion pack (1.35 kWh) as the rest of the Electric Series, good for about 3,250 m² (35,000 sq ft) on a charge. LCD for battery, hours and diagnostics. 11 or 14-blade EdgeSeries Flex reels, tool-free cutting unit change, telescoping handle. Standard backlapping.

Tapered traction drum for after-cut appearance. Off-board 650 W charger, about four hours empty to full.

Features

Built-in Clip Adjustments

Each eFlex walker includes six - easy to configure - clip rate options to accommodate specific cutting heights and playability requirements for every event or desired playing condition. Three color-coded pulleys can quickly be rearranged, with a single wrench, to match your reels and clip rates to achieve the desired result.

Proven Flex Suspension (Patented)

Superior contour following capability utilises an integrated "Flex" linkage system to allow cutting units to pivot around the center of the front roller to master undulations and prevent side-to-side scrubbing of the playing surface.

Advanced Lithium-Ion Battery Management

Lithium-ion battery power provides enough charge to mow up to 45,000 square feet on a single charge! One battery is designed to last five years and to deliver ample power to cut greens and acommodate key accessories such as groomers and light kits. No CO2 emissions, no toxic waste to dispose of, no liquid levels to monitor, no terminals to clean, no battery pack change outs during the work day and the worry-free list goes on.

Dual Precision Adjustment (DPA) Cutting Units

Precision machined cutting units maintain levelness and hold adjustments. Dual Precision Adjustment (DPA) cutting units – featuring Toro’s all new EdgeSeries™ reels combine to deliver a consistent, high quality cut and superior after cut appearance, while reducing maintenance with improved reel edge retention. DPA allows quick bedknife to reel adjustment. Harder reel and bedknife steel retain a sharp edge up to 3 times longer to minimise the need and frequency of adjustments, backlapping and grinding leading to healthier turf that stays green.

E-Z Turn™ Productivity

The patented EZ-Turn™ feature, if turned on, will automatically slow the unit down when turning at the end of a mowering path and automatically speed the mower up again after a controlled turn on the return pass. Improved control in turns reduces damage to turf, particularly in tight turns near a hazard, and produces better alignment on the return pass without sacrificing productivity.

Adjustable Telescoping Handle

The telescoping handle can be adjusted up or down for enhanced operator comfort and to accommodate tall or short operators.

Quiet Operation

Noiseless operation means that you can mow whenever you want without bothering nearby residents or other bystanders. Quiet operation enables operators to detect when reel malfunctions or potential reel damage occurs which could adversely affect the quality of cut and/or turf health.

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​.
