And then you have to push the second load thru the first pass? Ive done this for 40 plus years ..youd have that field a friggin mess your way...if you cant take it all in one full pass you dont shorten it you raise the blade and dont go so deep the first pass then go over it a second time..you can also over lap your passes as needed .
