West Tennessee | With some experience you can look at the rolls and tell how good they are. Borrow a new one and compare them. You will see the wear on the front part of the rolls. Replacing them is generally NO fun but well worth the effort. Get/borrow a puller and use a good air hammer. We run a WORN OUT 644 and get along great with it but keep our rolls in good shape. More good advice is to be sure your deck plates have a straight edge to them. If it's rounded (worn) inward time to replace those also. We run our deck plates quite a bit tighter than the operators manual says. IMO the manual recommendation is for really good big stalk corn and here in dryland country ours is a lot smaller. Maybe your plates are also too wide causing a lot of butt shelling. If you do put new deck plates on, borrow a suggestion from here and weld a piece of square key stock to the edge. Gives you more adjutment (closer) and doesn't hardly wear at all. I can't even remember how long ours have been on there now. Still very good. You CAN make this head work fine and give you very little trouble. | |
