Unless price makes it totally prohibitive, get one of the GT 2500 or 3000 series. Don't worry that they will be, "Too big," as once you have it and use it you'll find that is not an issue at all, and will appreciate the finer features such as shaft drives and good horizontal V twin engines and heavy duty serviceable hydros, the things that make them what the LT's are not and capable of doing things LT's are not. If maintained right, I can easily see a 2500 or 3000 lasting 20+ years like the old CC GT's of the past easily did. With the LT series 1000's and 1500's, to be honest short of having cast iron front axles, they are not much different from your basic Murray or Craftsman design wise, and are your basic 10 year lawn tractors strictly for light work. IMHO the 2500 series are the value leaders as far as the CC tractor lineup goes, the 2544 being basically today's equal to the 1980 682 I use, and the size is a great fit for small acreage yards for those who want a machine that can do some heavier tasks and is built to last.
