A little bit of TLC will make that 125 look GREAT. That 48" deck will make short work of your mowing. (that's why I like my 38" deck on my Model 800....more seat time)
Again, welcome. This is THE PLACE for all things Cub Cadet, from the Original Model through the current MTD made machines.
So, put on the coffee, pull up a chair and stay awhile.
