The 605 was the joystick control machine. My first time in a real joystick track loader other than our Cat 257 MTL. The 939 was a powershift model, no hydrostat so that obviously made it feel weird for me. The 605 would definately run circles around the 939, but thats to be expected. The 605 is in a market all its own, and in our area they are selling pretty well. I have seen 5 or so of them kickin around and the guys are loving em. They are great for workin around between houses.
I have now sat in all the major players as far as track loaders go, 605,655,755,943,953,963,973 and a 977L. By far my favourite is a 973C still. I would still like to play with all of them in a single day though. Get a real comparison going for them and get a feel for all the models. As I'm sure you guys can tell, I am a bit of an iron slut.... I make my way around the fleet.
