The Isuzu motor is a excellent cold weather starter, even without glow plugs, it is noiser then the kubota (and mine got a new muffler) operator needs ear covers for more then a few minutes use.
The steering on the 853 is not as nice as some of the smaller units I have run. I guess they are servo controled. When you move the lever it takes a second for the think to let you know how fast it will go for that posistion of the lever, which makes it harder to get both levers where you want at the same time. Drive it and you will see what I mean. Its not bad once you get used to it , but my wife does'nt like it.
My only other complaint is the boom cross member block you view of the top of the quick attach and makes it a little harder to pick up a attachment.
other then that I like it and it will lift right there with my 773 g
