Looking at a 5 bottom 546.  Trying to understand the differences with the models but hard to find info.  So, it looks like the 548 has spring auto reset.  Is the 546 auto rest too or do you have to back up?  What's the difference on the 588 vs the 548?  I've been told hydraulic reset isn't so hot.  How about the roll over models?  I'm going to use it occasionally to bury the trash when planting hay.  Will be pulling it with an 1850 with a Perkins.

Thanks!!!
