Hi Dave,
Congrats on the 8N!
However, in my experience, plowing with an 8N is far less than satisfactory.
I've tried...
Front mounted blade.
Worked OK in light snow, but the front end of the 8N is so light as soon as you build up a furrow it just pushes the front end over. Stomping on the steering brake helps a little but generally quite frusterating.
Back blade used forwards.
Reasonably effective, difficult to get the snow far enough off the road though as you're pulling. Still had a tendency to want to turn from the pressure from the furrow. Pushing backwards with the blade set forwards is often effective in light snow as the blade edge is angled in the direction of travel.
Back blade turned and used in reverse...
Useless, the geometry of a 3 point hitch with the tractor end of the lower links so high coupled with the general design of the 3 point hitch being very poor at resisting offset forces in reverse made it impossible to do much in this setup, at least on my steep, gravel drive. Perhaps on a paved drive...
If you're thinking of mounting your truck blade on the 3 point, I don't expect you'd have much more sucess.
My adice would be to get a good robust back blade and some REALLY good chains and plow forwards. Keep the Rover handy to pull you out when you try to plow too close to the ditch though.


Or other seriously stuck plow dudes...


Cheers
Peter
