I have a Swisher heavy plow and bucket. I blew up my 2500 warn twiceZ getting tired of tearing it apart and replacing the sun gear. Yes I undersrand the ATV is not built for heavy use but I do not own a tractor (yet) and need to use what I have. What is a snap block?
a heavier sized winch will help you IMO< but your electrical system might not be up to the task!'
maybe try using a very large marine grade deep cell battery to run the winch , over using ATv's battery/power system
and then hook battery up to tender after every use!
as you already know them buckets are killing your atv! its just not made for it
you's be WAY better off selling your ATV and buying a older used tractor, odds are if you shop right, you can get one with ZERO out of pocket money needed!
and will out work your atv several times over with a lot less wear and tear on it as well!
