First off that would be about the cheapest riding mower one is going to find and you get what you pay for.
From what I can find online they used a Briggs and Stratton engine (figures a primitive would complain without knowing Deere didn`t build the engine.)
Craftsman is owned by MTD as are many others including Cub Cadet which I sell.
There are cheap department store machines and there are higher end ones but will run much more then 1500.00.
We also sell Kubota which are virtually bullet proof but will run as much as 10,000 for a larger diesel lawn tractor.
and some trailblazing for riding/walking the rest of our 40 acres.
5 years for 1500.00 is probably about right if he is mowing several acres of lawn along with this,it wasn`t made for that.
If he had come to us he would have been told that but still not everyone listens.
