I've got a 1250 that I haven't done anything to since a brought it home. Just parked it in the shed, for someday.
Working on my 100 as I have, the extra room in a QL would be a welcome. As noted many times before. There all good if their taken care of. That's what makes this addiction what it is. When you begin, there will be times when you feel very intimidated by what your working on, but in time things will begin to go easier, as you begin to understand the tractor.
Pulling every nut and bolt from my 100 and getting it back together helps me understand what makes it tick. Long story longer, in time it will grow on you, and as soon as you have the bugs worked out, you'll be happy with your 1250.
(And you can always count on these guys on the site to be there for you in time of need) There isn't anything about cub cadet that this bunch can't help you through, and don't feel that your question might be a dumb one as I have in the past, felt like this would be a dumb question to ask, there is no such thing, but don't worry, they'll let you know
