Kubota GR2120
The Kubota GR2120 garden tractor lawn mower is the larger of the 2 models in the Kubota GR series. If you would like to know more about the Kubota GR2020 lawnmower, then just click here. The GR 2120 has a choice of mower decks that it can be used with. These are the either a mowing deck with a 48 inch cutting width or a deck with a cutting width of 54 inches. These mower decks are both connected to the garden tractor via a parallel linkage system. The mower deck has a cutting range of 3 inches. It’s lowest operating height is 1 inch above the ground and it’s highest operating height is 4 inches above the ground. Raising and lowering of the deck is done in small 0.25 inch increments. Both mower decks house 3 blades.
The Kubota GR2120 garden tractor lawnmower is fairly heavy, tipping the scales at 440 kg (970 lbs). It gets it’s power from a D782 diesel engine. This engine has a displacement of 0.778 liters and is a 3 cylinder. The engine doesn’t overheat thanks to a liquid cooling system. The fuel tank supplying the GR2120 with diesel can hold up to 18 liters (4.8 US gallons). This engine powers the mower deck by passing power through a hydraulic wet multi disc PTO clutch. It drives the wheels by passing it’s power through a hydrostatic transmission which makes the lawnmower an automatic with no gear changing required.
The speed of the Kubota GR2120 is controlled by a foot pedal. It has a top speed of 10 kph (6.2 mph) when traveling forwards and 5 kph (3.1 mph) when reversing. This GR 2120 comes with cruise control as standard. You’ll be glad to know that it’s a very versatile machine thanks to the fact that it can be used with a 46 snow blower during the winter or a 48 inch front blade for clearing snow/debris. There is also a rear bagger attachment to collect the grass clippings.

It cuts okay, no way as nicely as the old Wheel Horse which had a deck that ran on the ground. Hanging deck can never cut that well.
The huge expense and number of parts that break on this tractor make it one of the worst purchases of my entire 72 year life.
No “stars” appeared for me to click, on this site, btw.
I’m a 5th gen farmer operating a sizable tree farm started by my parents in 1973; we have owned 6 Kubota mowers since 1986 and the GR2120 is not on par with previous machines. Dad’s first Kubota was an ’86 B8200 that we got more than 7000 hrs use out of it during the 22 yrs it was in operation before trading it in on a larger B7800 4wd. At the same time dad bought a T1670, which the 2019 GR2120 was supposed to replace, but we’ve decided to repair the 14 yr old 1670 rather than rely upon the 2120 which is problematic and too rough riding for my elderly mom who still enjoys mowing her lawn. At first, the 2120 would continue travelling forward for 3-4 seconds after taking your foot off of the hyd pedal, and during that time, THE BRAKE WOULD NOT WORK! Several adjustments later, the dealer can not eliminate that issue completely. We are still negotiating with Kubota corp @ a solution. The 2 smaller T1400 mowers we wore out were also better than this 2120 in regards to the hyd trans, and def better than the numerous cheaper mowers that barely lasted 2 seasons between 1973-’86.
Bottom line with this lawn tractor is that its too heavy. Basic tractor with deck weighs almost 1000 lbs. Add a grass catcher loaded with grass and a 250 pound operator and you at about 3/4 ton. This tractor ruts up my yard. Had an old MDT from Lowes that was better.
I personally like the mower, my wife, not so much.
