I agree there's more than one way to plant a field/plot and with a conventional drill you can turn on a dime. But making a sharp turn while planting with a no-till drill isn't something I would do.
Here's the owners manual for a Kasco no-till drill, it also advises to raise drill before turning. Zophy had mentioned he had a Kasco no-till, not sure which model though.
