These are not my pictures, recieved them in an email once. That sounds like a good idea. Even if you off set the draper you could have a nice swather, with the cab up high you would see everything. The only thing I could see a problem might be the hp in the engine, I am not to familiar with Gleaners. For a cart you might not have a fast enough gearing depending on how fast you like to cart :) We will want see pictures of your cart/swather, I have always thought that an sp cart would be kinda cool, never thought of putting a draper on the front but why not.
