Which should you choose?
We will not advise between these two machines, because the drive differs (Tracks; 4WD); they were not built in overlapping years (1997–1998; 2004–2008); the 8400 T is on tracks, not an alternative to an ordinary tractor. The figures below are side by side so you can judge them yourself; each says whether it was measured, claimed or declared by its source.
