Yea, so it is a bit dated (the model), but I had been using an 1135 Massey, so this was a big step up in price and features. I am the second owner and the first took good care of the tractor.
The features are great and relatively reliable: economy PTO, reliable FWA, awesome 3-point control, durable transmission, and operator amenities. I have been using it for tillage. Pulling a 19 ft. disc, it goes 20% faster and uses 10% less fuel than the 1135. I had to add the cast rear inner wheel weights and put duals on it to get it to "behave" while pulling.
Very satisfied with the tractor. Do NOT leave the emergency brake on! You will destroy it and it is a job to repair. :( The price range for all these tractors (6180, 6280, and 6480) is roughly similar, but the 6180 has fewer electronics, mechanical shift linkage, and far less plastic.
