A grin came to my face when I read the comments about the MF300. My dad used to own one, traded in the old JD55 on it. As a youngster, it was the first combine I ever operated. It had a three row corn head and 13ft. grain head, a cab but no a_c. In 170+ corn at 20% moisture it came to a crawl. Dad used to joke that you had to get off of it and drive a stake beside it to make sure it was moving....lol. He later traded it on a JD4420 which he ran until he retired
