Had a
B7800 for 3 years and it was a great tractor. Looks like it's about the money difference because both should last for years if the
B7800 has been properly maintained. They both have near the same HP. The new B will cost you 0% interest for 42 months. There's a $4500 cash difference but if you have to finance either machine or have something else financed that you can pay off then the new may not be that much difference. There should also be some dollar value difference between the 300 hours needing repairs 300 hours sooner if all things are equal. The
B3200 I believe is the replacement for the
B7800. I now have a
B3200 and love it. Again, if your paying cash the difference in money is easy to see. If your financing do the math after determining monthly payments for both machines.
