I am thinking of updating my 92 1680, how does a 2377 and 2388 compare in hp and capacity? Have heard that a 2377 is closer to the old 1680 and the 2388. I realy dont need a bigger combine just a newer model.
The main difference between 2377 and 2388 is hp and grain bin size. Both have more power,sieve size, and concave area than your 1680. The hydraulics and cab are way better too.
Get the afx rotor and you will love either one. I have a 2388 with a bin extension and like the extra power. Either one will be a big step up from the 1680.
