If you need a "backup" machine of a smaller capacity, go find yourself a reasonable 4400_4420! Parts are plentiful and reasonably priced, plus the "bone yards" are full of these machines. My neighbor traded his 4400 on a demo 4435, only to trade his 4435 on an "immaculate" 4420; - with NO regrets. Deere North America continues to build replacement parts for these machines!
