A 7.5 wide plow is way too much for your sized tractor.I had a 6.0ft.on a L3130 HST,sub-frame mounted and that was all that it wanted for sure.The Moose plow should serve you well and it will be a lot lighter.We have put them on several ATV's and had good luck with them.
I agree. The plan would be to cut it to 5 or 5.5 feet.
Maybe, maybe not. If your dump circuit only has regen or fast dump, it won't run a pair of single acting cylinders. Regen applies full pressure to both ends of a double acting cylinder. As the but end is bigger than the rod end (that rod takes up space) it overpowers the rod end & extends. The extra fluid from the rod end makes the cylinder extend faster. Useful when dumping & gravity is trying to extend the cylinder already. If the pump couldn't keep up you'd get air in the cylinders.Yes, you could use your curl / dump function to control a power angle plow. You can easily adapt a manual angle blade to a QA plate and just manually change the angle. Having power angle is not really important unless you don't want to get off the tractor to manually change the blade angle.
For your $200 about all you can do is adapt a manual blade to a QA plate.
I went with PA so I don't have to get out of the nice warm cab. My tractor has rear remotes so I ran a pair of hoses up to the front and use the remote to angle the blade. I have about $600-700 in my plow and that's just for the QA plate, extra steel bracing, hoses, hyd. fittings, relief valve, misc. welding materials and paint. I already had the used truck plow sitting in the yard.
With chains on all 4 I have no problem sliding sideways with the plow angled.While it sounds good to have an angle blade you will soon find out that the more snow you load up front the more you slide sideways.
That is mainly because with a tractor we plow slowly while a truck plows at speed thus flinging the snow.
I say this so that you consider seriously the need for power angling that you would not really use.
Angle plowing with a CUT is probably only valid in minor events like 2" or so (which in reality don't need plowing).
When U have 6-10" events a blower is your friend.
With chains on all 4 I can push snow running over top of the plow when angled without sliding sideways.
