We pull a 324/327 with a D-17 on a hillside farm. We don't have too much problem pulling up the hills, but we use smaller barge boxes for wagons instead of larger gravity wagons. We have a little more trouble going down the hills because everything starts pushing. The biggest challenge is staying on rows going downhill. We run in low 1st and try to do the worst parts before the wagon has much corn in it. We don't have much trouble riding across sidehills. We know the D-17 will handle the slope, and the 324 is pretty wide compared to its height. The smaller wagons have a pretty low center of gravity, which helps. Your D-19 should work better going up and down you hills, but I imagine a 323 is narrower than our 324. I still don't think you will have a problem--just don't try to use too big of a wagon.
One of the old hillsiders up in the northern part of the county used to swear by putting triple-rib front tractor tires on his wagons, said it kept them from sliding as much when turning going downhill, and held the hill better when going across the slope. I don't know how much help it actually was, but I can see how the ribs might work better than the typical used 'slicks' most guys put on their wagons back then.
We run a 323 with a 60 hp tractor and a gravity wagon on hillside with no problems. The picker handles the hillside with ease; however, I only fill the wagon to about 75%--learned the hard way several years ago.
