I am not trying to argue. But I would encourage you to look at the test reports I posted. I do not know the exact transmission set up you have as there are multiple tests for most major types of transmissions. Below are some exerts from the reports listed in my prior post.
MX135X standard PTO 120.74hp, unladen weight 10,305 lbs
MT475B Standard PTO 122.2hp, unladen weight 11,795 lbs
MT535B Standard PTO 114.5- 138.2hp, unladen weight 14,780-14,835 lbs
The weights and overall dimensions of the MX135X and MT475B are similar and are also noted in the test reports.
Below are the two tests for the MT535B, I do not know your serial number so I am not sure which one applies to you.
I have no doubt that the MT535B is a much much better tractor for your needs. However it is a class above the old Kubota
M135X you replaced it with as shown in numbers that are from a certified test agency. It is interesting that the first test for the MT535B had some very poor numbers. I wonder if there was a problem with the tractor, hence the need for a second test.
