Here's what I run with: Loaded R-4's on all wheels. Aquiline MPC chains, (on REAR wheels ONLY) and a HLA Series 2000 7' all angle snowplow, with crossover valve, to dampen shock to the loader arms. I usually have my backhoe on, which serves as 1000+#s of ballast.
A blower would be a waste of money, (IMO), and would render you loader-less, so 2 strikes against you in your area.
Mid-mount blowers for front end use are not only expensive, but unwieldy, difficult to install/uninstall, etc.
My plow is on and off in minutes with QA and two quick coupler connections on the loader torque tube, run off my loader joystick's trigger switch, through a diverter valve. I allows me two pairs of rear remotes, AND a pair of hoses, (mentioned), going to the loader's torque tube.
So I would NOT recommend using just front chains; that can cause drivetrain issues because the front wheels turn at a different speed than do the rears, and there is an allowance for slippage of the front wheels as they turn corners, etc. This is compounded when in 4WD. It is further compounded by the lack of additional traction on the rear wheels that don't have chains to even out traction issues.
Add ballast to rear, chains on rear, front all angle plow or manual angle one, and keep your loader usable with your bucket. All set for most winters.
