The R4 industrial rims can't be offset like the R1 Ags can unfortunately. They are already loaded with bio ballast.
I hear you on the plowing downhill. I can really feel the extra drag going uphill on the dirt road out front as opposed to downhill. I managed to clear a path downhill to another road, but plowing uphill to the main road is a no go.
I can probably pick up a blower before next winder for under $1k hunting Craigslist. From what I understand the blower is the great equalizer on drifts, slow going, but you can creep on through despite having half the tractor needed to plow what showed up last-night. Ironically I have a SSQA single stage blower I'm looking to sell to a neighbor. It use to be a 3pt before the previous owner converted it to hydraulic & SSQA. I got a stupid good deal on it when buying a fuel tank from a guy, so picked it up as a project or flip of some sort. I don't have enough flow to run it. Easier to sell & get a 3pt one it than build a PTO power pack to run it or convert it back to a 3pt PTO unit.
My inclination at the moment it to get some chains for the front & see if that is enough. I think spacers are going to be the same ballpark as chains for the front. If the chains up front aren't enough I can still use them & that way I don't have to mess with my track. Widening my track means my rear blade won't cover my tracks at an angle & several other implements won't fit the clear your tracks guideline.
Any recomendations on what style to get? I see no reason not to go with the V-Bar ones for the extra cleats, I don't have to wort about tearing much up.
