Whats everyone’s thoughts on these compared to a direct drill? Would they be better for stitching in clover? Are they easy to take the roller off the back and use separately with the seeder or is it a pain so you wouldn’t bother? How many passes do you actually need to get enough tilth in grassland? Realistically what weight and hp tractor do you need in the hills to handle one with them being close on 2t? I see they do an alpine model with smaller lighter roller, would this be ‘enough’ on grass into grass or should you just stick with the heavy roller?
