Farm Life Plow Attachment bug

Whenever I play Farm Life, I always have the same glitch.  It happens whenever I try to use the plow attachment for the small tractor....  I go to hook up to the plow, but whenever I do it just duplicates the plow attachment, and then it won't actually plow anything when I push the jump button.  And if I disconnect the plow from the tractor, then I can't get back on the small tractor and the plow gets duplicated again.  Please help, I really want to enjoy this thing, but sadly it appears broken.  I am sad.  Rockatoa, Brickticks out!
