i have a k combine, gas burner, 13 ft head with hume reel and love bar, 2-row 38 in head and 3-row 30 inch head, i love this combine, have run it for years, good grain sample, easy to work on, takes 5 rows of 30 in beans great, and 3 rows of corn real nice. just had a new sheave put on as it was eating drive belts, $3600.00 for the both upper and lower sheaves, other than that this machine hasn't cost me hardly anything to keep it going. it doesn't owe me anything! i bought a larger combine that takes 6-rows, but am keeping the k for a back-up machine if needed. i don't think you'll be sorry about this purchase.
