Yes, my main reason was that this was the tractor I probably spent the most time on. Dad has a 1256 as well (got it after I'd married) and a 560 that we've had since we started farming in 76...In the discussions on the Red Power forum that happen from time to time about which IH was best, the 856 wins more than any other model, with the 1256 & 1456 coming in right behind it.
I really like it when they are kept up nice and shiny red! Like that one.
I've converted all my big tractors with LED's...and where, may I ask, did you get the lights. Looking to upgrade my 30 year old Ford tractor.
