The Model F3500 is for the farmer that is running a 24 row (60’ based on 30” rows) planter. The F3500 is a front-fold style bar when in transport position is only 11’ 10” wide. This makes the F3500 the narrowest transport width 60’ sidedress applicator on the market. The F3500 can also do 16 rows when the outer wings are left folded up. The applicator uses the patented lift system that is used on the F3400 & F3450 sidedress appli-cators. Wing flex is no problem with the F3500.
