as mentioned by others a rear pull combined with your existing v plow could be a great combination. . As far as speed with my 74" prononvost i would imagine that i could go 3-4 mph with 6-10 inches of dry snow (jd 3720 35 pto hp claimed)- I know that at 4 inches of dry i can just go full speed B range-7 mph.
The downsides to a rear pull are pretty well known- deep drifts could be a problem though that size tractor should be able to get through several feet of snow. Too, any blower requires care on a gravel road. Pronovost has a kit that replaces the hydraulic
rear blade with a set of wheels - might be great for early or late season- i tried to link to it but all Pronovost sites give me a 403 error today
I wonder why you are breaking shearpins and having so many chain issues, typically dual auger machines are intended for and built for severe service. They also tend to use a good bit more power than a single auger thus slowing things down a bit. I think its very possible/likely that some blowers are a good bit more efficient than others. I know when i replaced my kubota with frt blower (about 4.6 hp per ft of blower) with my current set up (about 5.8 hp per ft) that instead of being able to go 25 or 30% faster on a given snowfall i was able to go at least double. Too, the control given by the commercial chutes is great especially in constricted areas or near buildings. I have a couple of dangerous sections along my drive and previously i would build berms with a blade to help keep vehicles on in case of sliding, now i use the blower to build higher and thicker berm than i could with a blade.
How wide is your road? that might change the best clearing strategy. Maybe as suggested you should plow to the center then blow from there or blow every few storms depending on the shoulder available and type of snow.
