Does it move any slower when it's cold?
Well back for 1-day then head back up around Fort-Riley. Anyway yes it moves slower when cold, as does any hydraulics. I just start it up and let it warm up.
Are the legs always extended that far?
Or can you set them up narrow for a tight access?
You can set up in as narrow as 7.5ft and wide is 13.5ft, you can use many combinations, narrow on 1 side, 1 leg narrow, ect ect. But when you set up narrow you loose full rotation, you can not rotate past the outriggers. So you want to be facing the area you need to work in. We always try and set up in the full width as much as possible. Here is the specs on outrigger placement.

Go to the top left of the picture and you can change it to the footprint diagram to see the outrigger placement.
One thing to remember on the 15GT and 18GT, is the outriggers are straight. So that means if the terrain is steep or say working in or next to a ditch you will have to use cribbing to get the machine level. The 23Gt outriggers are hooked you can have 1 outrigger as much as 3ft off the ground if need be, so they will level in some pretty extreme places. They have some pretty good pictures on there web site.

They have several pictures of my machine, they are numbers 2,3,4,5,6,7,87,88,151,152,153,154,155,156,157,158,159,160,161,162. They also put us in there add in Lift And Access magazine for Jan and Feb....
So thats just somthing else to think about, what the terrain is like in your area....
