Take the loader off and it is even more maneuverable.
Yep, my FEL usually stays off. It's like a different tractor!
I am quite the opposite. I usually leave mine on cause I am usually blading or doing dirtwork, or cutting firewood. All things that the loader comes in quite handy. I even leave it on when bushhogging. Partly due to the ~1100# cutter I use.
But I DO take it off when tilling. Cause when the tiller is in the ground, there aint much weight on the front end, and with the loader it cuts quite deep ruts and compacts the soil alot. Without the loader, the fronts dont cut in much at all.
