What are the pros and cons? I have a double axle 14+2 trailer now and looking to add a second .... Almost solely for mowing, pine straw, etc. With the axle rated for 3500 it should hold 2 ztrs but maybe not mulch. At the moment it would haul a push and 60" ztr. Closer to leaf season I would need to transition the walker into use so a few weeks both would be needed. In my area a 2 man crew would be the most efficient and I currently don't have any properties where 2 mowing guys would be needed. I assume the price isn't that different and I'm better off buying for future expansion.
