Hello everyone, I'm happy to be here with you guys. I currently have a 1250 Quietline that needs a motor. I joined so I could post any questions I have along the way of replacing the motor.

Welcome to the forum Ben!
Welcome Ben. You have found a place that will give you answers.
FYI
You will need an AQS engine, 12-14HP to repower that Q/L
Good luck!

Welcome Ben - your 1250 Quiet Line can be a very nice tractor when running and operating. Pics would be nice so we can see what you have, along with your rough location since you only show U.S.
I think what David S was getting at is that your 1250 would have originally had a Kohler K-series engine model "K301AQS".
The K301 designation makes it a 12hp. The letter "A" suffix means it has a special oil pan (in this case so it fits an IH Cub Cadet frame). The letter "Q" means it's a Quiet series engine, and the letter "S" means it's electric start.
If you're looking for a complete replacement engine then you'll need a K301AQS, or you could also use a K321AQS which is a 14hp version or a K341AQS which is a 16hp version. There is also a K241AQS which is the 10hp version which will work in your 1250 but I would assume you really don't want less hp.
I also think David was also implying the AQS engines are somewhat harder to find. They don't seem to be as readily available as the earlier Kohler engines for Cub Cadets. Can you use an earlier one??? Well, maybe but it depends. It depends on whether it's 12hp, and depends on whether the casting has the holes for your electric PTO clutch, and depends on some other things.
Can you use a different Kohler K-series block? That depends to. I don't like going that route. Many of the non-A suffix Kohlers really won't work. I wouldn't recommend getting into efforts to cut off the casting on the base or other things like that. It can get into a lot of work that in the end doesn't work well.
So, feel free to post and ask away in the regular Forum thread.
