Anyone know anything about this? How does it mount onto the planter? Straight up and down like the regular hopper? Or at a 45 degree angle like the 33? Is the veg. hop. for the 71 essentially the same thing as the one for the 33? I understand that it takes the same plates, is that true? Are there any pictures of a 71 with a veg. hop. attached? Any help is appreciated.
