I haven't seen an LS at a Lowes near me. Runnings has finally started carrying Summit tractors and I've walked by a couple out front, but not looked too closely at them. TS doesn't sell them nearby.
When I was tractor shopping I quickly ruled out LS as they are sold by the local dealer that went under, changed their name, and did a bunch of shady stuff a few years back. I actually bought my Cub Cadet from them and the relationship soured as they kept telling me the engine hunting and surging was normal, and when my mowing deck had an issue they returned it claiming it was "fixed" and told me to pay them. I told them I'd pay when they actually fixed the machine and not sooner so they threatened to sue me and I told them to go ahead. During this time, Cub cadet revoked their dealership likely due to many similar complaints.
Ended up taking my Cub to a different dealer who fixed it first time. I then left a negative review online about their incompetence and unwillingness to support the products they sold, only to have the owners wife reach out on Facebook and threaten me again, told me the owners changed so it was now her son's and they were "innocent" yet, walking in it was the exact same people selling, servicing, and driving the trucks. I told them to get lost and will never go back. I truly feel sorry for folks walking in there now! They have since rebranded and are back selling Cub cadet, LS and some other equipment.
