• Even a little weight will make a difference, but where it is, is very important.
• Adding 200# on the back wheels plus about 50# on the front wheels is great.
• Your "Foot print" is very important, how much rubber is on the ground, and less is better. Traction is PSI (pounds per square inch), bar-lug tires will give a lot more traction in mud, snow & ice than regular turf tires can. We use skis & snowshoes to glide gently on the snow, giving us a bigger footprint; but for traction, we want a lot of force in a very small spot. Also, new tires are so much better than old worm rounded tires.
Chains really can improve traction but can also damage pavement.
• Where the weight is counts: Avoid behind the rear axle, it actually lifts the front, reduces steering control. Very best place is IN the wheels, a liquid like "RimGuard" is the very best most safe liquid, at 11#/gal (16" front tire holds 2 gal, 22# -- and 23" rear tire holds 5+ gal), you don't see it and it's out-of-the-way. Second best is on the wheel, inside the rim, bolted to it (and on the inside side of the wheel is better). Worst place is to hang it out behind the rear end, plus it's often in the way. Also, always have 20PSI in the tires in the Winter (firm tire = traction), and only 10PSI in the Summer (soft tire = gentle on grass).
• When the snow thrower is up, it is a lot of weight on the front, but when it's down in use and working, it actually lightens the front of your GT, then we loose steering control and get side-sway. That's why we need to have weight on the front tires, out from the frame and very low, again, fluid is the best here, wheel weights second best.
• But, all this being said: it's what you have to work with, what you can get and how much $$$ you have. You don't need weight when cutting grass in the summer (and fluid has to stay in), new tires or new weights can cost, use what you have. But add weight in the Winter, and with all the weight, don't drive it like a 4-wheeler in the woods or you will damage things.
