I went to the local JD dealer for some quotes. First off the salesperson acted like I was bothering him, and second there was no wiggle room or discounts. I went in to price out an X750 with 60HC deck, and it was more than the Kioti CS2520 with 60 deck I bought. That JD dealer is now out of business, most likely due to their business practices and lack of good salespersons.
My Kioti dealer is 45-50 minutes away. Not happy about that, the Kubota dealer is about 10 minutes away. If Kubota would redesign their treadle pedal to a more friendly twin pedal arrangement, I would most likely own a Kubota, even though the quote was $3K above what the Kioti cost me.
I have several friends with hydrostatic Kubota tractors, and they say they aren't fond of the treadle pedal either. Going forward is fine, but when backing up, especially when blowing snow with a rear blower it gets cramping for them with twisting their body for rear viewing and having their heel in the reverse part of the pedal to back up.
You should maybe drive the 30 minutes to each of the dealers and test drive both.
There is no frame comparison to a lawn tractor frame, and a BX, CS, or 1025r compact tractor frame. All are designed for heavy usage and less likely to twist during regular operations. Over decades they with not fatigue with thousands of hours of use.
Some JD model 1025r have some front-end issues with the steering. You should research that.
My personal opinion is that Kubota is a better built tractor that the Kioti. But I bought a Kioti. I'll see how it goes. So far mostly happy with it.
The hydrostatic filter placement under the floor deck is a beast to get to and replace. Kioti used to have a bolted in removable frame strengthen plate on the lower frame rails. On my model that bolt on option is gone, the plate is now welded in place. Most likely as a cost cutting design maneuver. While it does make the frame stiffer by welding, it makes getting to the hydrostatic filter a real bear. If you do buy a Kioti, I'll instruct you as to removing the floor pan, and slipping a oil filter band wrench into a very limited space and loosening up the filter. I did not have to remove the mowing deck either.
TYM and other brands are available, you can get a TYM and have decades of good operational service. All brands sometime have lemons.
You should do a lot of homework before you buy. Test drive all of them.
