I don't think the B-80 came with stock Wheel Horse headlights, but the regular C-series headlights will fit and work OK. Can often find the buckets and lens for about $20 each on eBay, plus wiring and switch, (and TSC lights are a lot less, adding side lights is easy, remember to add tail lights too).
As 'bairleaFarm' said, Weight, Weight, Weight is the secret to good traction when plowing. That tractor/axle can take a lot of weight. even 150# per wheel is fine, but then with a plow, you must add a little weight to the front wheels too for steering control (10-20# @). Lug tires are better than turf in the Winter, or use chains on the turfs. Inflate all Winter tires to 20#. I'm sure you'll enjoy the B-80 much more than using a Craftsman.
The tube is for Rear implements (bottom-plow, tiller, tines), cable goes from the "Bellcrank", thru the tube, to the implement.
