yes do a search here about plows and you will, find a ton of GOOD info, I know I posted a LOT of it LOL
and yes a 60 inch blade is the diea size for a ATV, as at full angle its ONLY about 53 inches wide, NOT a lot wider than your tires, and , when SNOW is deep, you NEED full angle to PUSH thru it, s it deflects it and takes load off the front end of things, making plowing easier on ALL things,
there are pro's and con's to ALL plow designs, again covered in other treads
I am partial to MOOSE plows, as I have seen the abuse I have giving mine over the past almost 20 yrs and its been super an still works as good as it did day one, and I use it ton MANY things I am NOT supposed to!
a LOT IMO comes down to HOW Much snow you tend to get and need to plow
MID mounts are strongest set ups and cheapest, by MOST all makers
I say a winch to lift is the WAY to go, hand lifts grow OLD fast and electric and hydraulic steps get sure costly fast and not really needed if your of able body, YES 110% NICE to have, but for the price?? have to say NO!
again, do a search here on plows and you will find all the info you will want and more!
including how, many times, HD springs are needed on the front end to support a plow!
