Greensmaster Flex 2120 Petrol

Walking your greens has never been easier. The Greensmaster® Flex™ walk mowers improve upon the industry leading cutting performance you’ve come to expect from Toro. Add improved productivity and simplified serviceability to the list and you’ll quickly understand why the all-new Greensmaster® Flex™ 2120 promises to make the best greensmowers on the planet even better!

The Greensmaster Flex 2120 Petrol is also commonly known as: GM2120, GM 2120, Greenmaster, Green Master 2120, GM Petrol, Flex greensmaster, Toro Greensmaster



The Greensmaster® Flex™ 1820 / 2120 Series mowers deliver pristine results time and time again. Greensmaster Flex mowers cut closely to follow severe undulations at extremely low heights, and provide an excellent solution for greens that require precision mowing. The unique and patented Flex suspension system utilises an integrated linkage system to allow cutting units to pivot around the centre of the front roller, which prevents side-to-side scrubbing of the putting surface. All functions are easily controlled from the operator station, including both traction and reel engagement.

The Flex 1820 / 2120 features a heavy-duty industrial 4.3 hp (3.2 kW) Subaru® gasoline engine and reaches transport speeds of up to 5.7 mph (9.2 km/h). With a cutting width of 18” / 21”, operators will appreciate the precision handling and pristine after cut appearance that the Flex 1820 / 2120 delivers. Both units feature an all-aluminium die-cast precision frame and a belt drive transmission and can achieve cutting heights as low as 1/16 inch (1.59mm). All Toro Greensmaster mowers feature patented dual precision adjustment (DPA) cutting units and require no regular greasing as part of a preventative maintenance plan.

Configuration Options:

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