No it won't hold on a hill as I found out to my chagrin soon after I bought my tractor. /forums/images/graemlins/blush.gif However, I often have three things holding my hydro tractor in place when stopped. I have the emergency brake on, the box blade lowered, and the FEL lowered as well. If it's on a really steep slope, I place the bucket with the sharp edge digging in as well. My tractor's going nowhere if I have anything to say about it. /forums/images/graemlins/smirk.gif
Also, I sure wouldn't want to have to clutch, shift, operate the throttle, and operate the loader joystick all at the same time when doing loader work. It's really nice to operate just a foot pedal and the joystick. Gear tractors do a lot of things well, but I can't see them equalling a hydro for FEL work.
