Features of The Greensmaster® Flex™ 1820 / 2120 Series

Greensmaster® Flex™ 1820 / 2120 Series brings you the most reliable walk Toro golf course mowers available in the industry. If you are looking for a mower capable of delivering pristine results for years, you must consider The Greensmaster® Flex™ 1820 / 2120 series. These mowers can follow undulations even when the heights are extremely low. Their ability to cut closely provides you with the best solution for greens demanding precision mowing. This series comes with Toro’s patented flex suspension system. 
This unique system uses an integrated linkage system allowing the cutting units to pivot around the front roller’s center. So, there is no problem of side-by-side scrubbing of the putting surface. The operator can control traction and reel engagement and other functions from the operator station. This series is powered by heavy-duty industrial 4.3 hp (3.2 kW) Subaru gasoline engine. This engine provides you with a transport speed of up to 9.2 km/h (5.7 mph). With 18”/21” cutting width, Flex 1820/2120 offers the best handling and delivers exceptional aftercut appearance.          
Both mowers in this series have belt drive transmission and all-aluminum die-cast precision frame. The lowest cutting height you can achieve is 1.59 mm (1/17 inch). Like other Greenmaster mowers, these two units also have DPA (dual precision adjustment) cutting units. There is no need for regular greasing. 
This series provides you with the following two configuration options: 

  • Greensmaster Flex 2120 – 21″ Cutting Width
  • Greensmaster Flex 1820 – 18″ Cutting Width
