1) The three point hitch, when attempting to raise slowly, jerks the crap out of itself. It is jerky/bouncy and feels like garbage. With 7' sickle mower sticking out 7+feet out on the side it is going to break itself by jerking or I have to raise it full blast all at once.
2) Transmission has more slack than my 52 8N Ford. The higher the gear, the more noticeable the noise and slack. Drive on almost level ground in 4th/high range and go slightly uphill, to level, to down hill and you'll hear the gears go from tight on back of gear, to loose, to tight on front of gear. It's like it's worn out the day it was produced.
I have rebuilt 2 gear transmissions in older tractors and I know what it sounds like to have too much backlash in your gears. This transmission is a sloppily-made, non-precise, embarrassing gear box.
When I drive it down the road to the neighbors they can "hear Kevin coming down the road", and they are not talking about my engine. They can hear those gears just a growling and whining.
3) No hand rest on right side. Doesn't really bother me.
4) Very light/small final drives/light rear. It is very hard to keep the rear of this tractor on the ground with FEL. My neighbors Branson 3510 weighs 1000 pounds more according to Tractor Data.com, and can use FEL all day with nothing on back. And my back tires are both loaded full of washer-fluid.
5) Good motor it seems, good front axle, but without being able to expand wheels out far, the L-series (an economy tractor) is made to roll over. Must use the ROPS. I have been on 2 wheels more times than I can count. Removing FEL helps a lot.
6) Will climb up and down anything---period.
7) Gas cap in stupid location, inevitable that messes on the hood of your 20K machine will be common.
9) Power steering is sluggish and when it tight areas going too slow or stopped it sometimes doesn't have the power to steer. All fluids are proper in this unit, just a weaker steering system.
10) Price point is the strongest point of this tractor aside from that motor. Good motor, lots of power and quick starting.
11) Taking into account the jerky 3-point hitch, which dealer and Kubota rep told me is "normal and won't ever hurt anything", the crappy gear box (1/2 as good as a 60 year old Ford), the power steering weakness, and light butt-end, I will not recommend this tractor to someone who needs to do a lot of work. It'll be okay for a hobby farm of 5 acres but get up to 25+ and you'll be regretting and wishing for a NH, Mahindra, JD, or Branson.
12) Fuel consumption too. That thing can blow through 1.4-1.8 gallons per hour bush hogging.
13) Transmission gets hot to the touch when brush hogging (I have a 15 hour brush hog that I do every spring here with 5' Land Pride. You can't touch the trans, it's too hot. It's all hill hear, must be in 4x4 and going in 4th/low range.
I bent my rocker arm on my Superior 394 mower a little last year and then now I use it on my Kubota and that jerking 3 point hitch bent it more and more, so I had to get another rocker. That 7' bar looks like it's going to snap when trying to raise this things slowly. I threatened Kubota with lawsuit and they told me to go fly a kite. If enough people join up, I'll go for class action suit. All they have to do is remove top trans cover and adjust some valves. But they will NOT do it. My dealer won't either.
