The 160FWA will pay for itself in time and fuel saved in about 2 years. The l2 will pay for itself in about the same time because of the time and fuel saved as well. And down the road the l2 can carry an 8-30 head or a 6-30 head and trade to a 12 row planter. I moved from about what you had several years ago to an 8050FWA and an excellent N6 and think it was the best move I ever made. Sounds like you can cash flow it!
