Hi Chris,
While this site has been around for awhile, I think it is really starting to take off. I joined back in June of this year and I think I was the 267th member and I see today there are 319. If this growth continues, we should soon have the diversity in owners and their machines that very few questions will hopefully go un-answered.
Having said that, I think the most valuable tool you can own is the proper service manual for any machine. Even if you don't normally do your own repairs it will help better understand what's going on, and as an added bonus the first time you use it to fix something small it pays for itself around the second hour.
Hope to talk again, and if I can help I'll try and do what I can. I've got a 763, but am still kind of new to the skidsteer world.
Don
