I have a 3038E compact tractor, a 3 cylinder, 37.3 HP, 91 CID engine, 2,200 # weight and need a bigger tractor. Looking at a 4044R which is only 6 hp more - 43 Hp, but has 4 cylinders, and 133 CID, and weighs 3,770#. I am being told this will have more actual power than the 6 HP increase would indicate. Will be used mainly for hauling dirt & gravel in the bucket, some digging and leveling of ground. What do you think? I can go up another 8 hp with turbo for $3,000 more, but will I need that?
