Hey guys we run a 8360 Agcostar which is based on the same machine as the older massesy's McConall or something like that. Only one thing I can say about this rig, What we were looking for was a brute horsepower machine, without all the toys like powershift tranny and such. The transmission is great as is the engine. We have 2000 hrs on it mostly pulling a landoll 7-30 weatherproofer II in the fall and a soil finisher in the spring. I absolutely love the tractor except for the air filteration for the cab. Its amazing the power this brute has and how comfortable it is to ride in. We have had alot of brands of 4wd's in the past (including deere's and 7580, 8550, 4w220, 4w305) The Agcostar is just a great tractor if you dont need all the toys and like a brute power source, if the masseys were anything comparable to this one I wish we would have started with the masseys instead of the other colors. Granted the allis machines are good but they really dont compare to the Agcostar in terms of comfortable ride and brutual power, but they are older machines too, so I cant knock them.
