This is my first time to post a thread. I want to know if the 4540 tractors that have been talked about are the same as my LS 4540. I want to get my various filters and fluids from NAPA and I see some postings on filter numbers but I was not sure about models. I have 28 hrs. on my tractor. It is the only tractor I have ever owned so I have nothing to compare but I think it is great. I have 35 acres in Colorado and have been tractoring to my heart's content all summer. Smiling all day long.-----Bob O
