An Excellent Mower
Model Year: 2013
I bought this Kubota GR2120 in 2013 to replace a Kubota T2080, bought new in 2012 but that had proven ill-suited to mow the sloped areas that surround my house. The T2080 had a heavy front end, and a light rear end where the only braking capability was located. It would thus climb easily but just slide down when getting downhill---a chilling experience, at best. Otherwise, it was a fine piece of machinery that resold to a Kubota fan with some 28 hours on it and a valid transferable warranty. The GR2120, being 4WD, just goes up and down slopes with ease, mowing is impeccable, diesel fuel consumption is low, controls are easy to use, built is sturdy, seat and operator platform are comfortable, turns on a dime, "glide steer" prevent any turf damage caused by the 4WD, greasing and oiling points are easily accessible, mounting and dismounting of the mower is straightforward, and it will easily tow its own weight---800 pounds without the mower---on a 16 cu. feet Swisher all-terrain ATV cart full of dirt or firewood. I haven't as yet changed oil and filters, so have no comment to provide on this. This support the high ratings. I gave it a 4 on performance because it would not back up on slopes, it simply stops moving. This is probably due to a "weak hydro" as other reviewers have mentioned. So, the resulting advice being: if you need to back up steep slopes, or want using attachments needing lots of hydraulic power or expect to haul heavier cargo, you should consider the BX series. For my needs, the GR is just okay. But you will be carrying more weight on your lawn, from 960 pounds for the GR to more than 1,500 pounds for a BX. ---------------- After Thoughts: After posting this review, I read replies to my forum comments on Tractobynet that appeared to come from more mechanically savvy people---opinions I thus want to incorporate into this review---so as to provide a more comprehensive picture of the machine. It was brought to our attention that the “backward lack of power” we experience while using a GR2120 comes essentially from the speed pedal being factory limited in its backward course for safety purposes, thus limiting backward speed (and thus backward power). It can be modified if you want, at your own risk. Now, when you think about it, how can a hydro trans. be powerful enough when forwarding and then be “weak” while backing off? Yet, the machine should be, in my opinion, considered a high performance ride-on mower, with capabilities far exceeding those of most ride-on mowers, but not as a subcompact tractor. Consider the aluminum cast transmission and gear boxes vs. cast iron on subcompact tractors, difference in weight accounting for sturdiness (from 800 to 1,500 pounds without mower) ,etc. So, again, carefully assess your needs. That could mean wanting almost limitless possibilities on a machine (I used to do that) or, coldly considering what you really will be doing with the machine. If it suits your needs, the GR2120 is a really good piece of equipment that is proving very satisfactory to me. And : “Glide Steer” really does wonder on mowing in closed corners, I can tell you. If your needs are those of a robust subcompact tractor, then go BX, and don't be disappointed by "under buying". Raber ---------------- UPDATE, as of August 12, 2014 - 50 hours of use on the Kubota GR2120. The machine continues to offer outstanding performance, the more I get used to it and learn to make the best out of its capabilities. Mowing is clean and manicure like. Towing a cart with some 800 pounds of dirt, rocks or crushed rocks on difficult terrain poses no problem if I am careful with the limited ground clearance of the rear axle, and take off the mower in narrow spots. Never lost traction, but never ventured in swampy terrain either. I performed the recommended maintenance at 50 hours of use: changed transmission oil filter and top off the oil level in transmission with Kubota UDT transmission fluid. A simple and straightforward business. Changed the engine oil and oil filter. No problem, except that you have no room to maneuver a lever filter wrench. You have to find a socket that caps over the filter and rotate it with a remote ratchet. Adjustable socket is cheap and easy to find. Changing engine oil is a lot easier with the mower removed. Filling is easy, especially if you take the pain to measure exactly what amount is needed and damping the new filter with same engine oil. With the engine running a few minutes, you'll find the oil level exactly where it should be. Changing the oil of the mower gearbox can be simple and straightforward. You just unmount the mower, tie the driving shaft with a piece of thread so it won't swing around and prove a nuisance. You take off the big filling hole plug and raise the mower on its end, with the open hole facing downward. You need a helper to hold a small can to recover the fluid. Put the mower down. Remove the plastic extension chute, because you will need to raise the mower on the other end for filling up. Measure 150 ml of proper oil in a measuring cup, raise the mower on its end, with the filling hole upward, and ask your helper to pour down the oil. Have your helper screw back the plug, put the mower down and you're done. Other maintenance tasks to come, but only in a hundred more hours of use. So, it appears so far that the GR2120 is quite easy to service. Raber
Pros: Excellent mower on all aspects and more.
Cons: Limited hydro power for heavier work.
