Re: Looking for a new mower
The main worry with the LT is the T40/K46 trans. The motors are great. That was the most popular commercial zero turn motor back in it's day. If the unit hasn't been abused I would take it over any L100 / LA / D / E unit just for the Kawasaki motor. The LTs are a pain to work on because the fenderdeck is welded to the frame.
The E you buy at Lowes or a dealer are the same.
