</font><font color="blue" class="small">( How much hp is the 2120?
It appears the TN may have a wider bucket, but the 2120's bucket appears almost as wide and taller? Is it just the picture?
The 2120 also appears to be just as big in some respects, especially the hood line. The TN does have much bigger tires, and also appears to have a much wider stance. )</font>

The 2120 is 43hp, but it built on a considerably larger chassis than the TC45. It is basically the same tractor as a TC55 with less hp. I have both a TN75D and a 2120. The TN is considerably larger even though I share most implements between the two. The TN will pick up way over 3000 # in the loader while the 2120 is maxed out a little above 2000#. My TN handles the 84" bucket with ease, while it is a little large for the 2120. The 2120 is better off when I run it with a 72" bucket. The 2120 actually has more hp than it is rated. Mine has served me well and done much hard work since 1987. My TN has 16.9 x 30 rears and the 2120 has 14.9x26 rears.
