I have a 383 SXG, so seed and fert onboard.
Placement and rate accuracy has been really good. I have had next to zero issues with the toolbar. The odd packer wheel bearing has come loose and a few hydraulic hoses between shanks getting cracked. Mostly at the fold.
Trash clearance can be an issue. I don't seed between the rows but I try to harrow cereal stubble and pea stubble gets disced in the fall.
