When my father bought his L2800 new in 2008 he was pretty proud of it. He'd owned dozens of tractors around that size in his lifetime yet this was one of the nicest he ever had, and his only HST. The first thing I noticed was a baseball sized bulge in the sidewall of one of the rears. He took it back and they replaced it, but with a different brand so the treads weren't the same. They achieved the goal though, of holding the tractor off the ground.
Maybe I'm too picky yet if I bought a brand new tractor I would want the tires to match. Either find another like this one, or buy two of another brand.
