I have an L130 (w/ the Kohler). I used it prior to relaizing I needed a real tractor. I was essentially using it as a brush hog, mowing over small trees, 7 foot tall blackberry patches, 1" diameter scotch broom, and taller than me grass and weeds. I figuratively beat the crap out of that thing. I even popped both front tires, ran over a few metal fence posts and random fencing with the mower, and hit more rocks than you can imagine. Heavy duty stuff!
...and that was the fisrt 12 hours of it's life.
I changed the oil and filters (the air filter twice; it was comically jammed with biomass), installed a new belt, and put new blades on it.
Mows like new.
My only complaints have been the smoky starts and wiggly steering mechanism.
I don't think I did too bad for going to **** Depot to get remodeling supplies and coming home with a riding lawn mower on a total impulse buy /forums/images/graemlins/tongue.gif
