1991 has Cummins engine, 4500 engine hours, bottom of hopper needs some work otherwise its field ready with a little maintenance. I will charge the AC when its sells, it needs to be charged every year but then will blow cold all harvest. Its been a great trouble free combine for us we just upgraded to a flagship machine. Have a set of pea concaves I will throw in with it. I have a nice 30ft 1010 straight header for it with a finger reel I will sell for additional price. I also have a pickup head and a 8 row corn head I would like to sell. $8000 for the combine $15000 for all
