Should the Weight Be on the Wheels or the Scoop?

Ariens mounts there motors behind the axle, moving weight of the scoop. It definitely makes it easy to handle; so far, it is the only 30" that doesn't scare my wife. However, not scaring my wife isn't the main criteria. If the weight is on the nose it resists riding up. If the weight in on the rear wheels it aids traction. Going uphill, additional weight transfers to the wheels. Going downhill, it transfers to the scoop. Although that may or may not be significant. So which is better? The most bias to the wheels as possible? As a side bar, several snow blowers have optional weights to go on the scoop. These typically are on the top, a bit forward of the skid shoe. And rather small, 10#. More like an offset for a cab. Is higher overall weight better? Is it better to have 80# on the nose and 170# on the wheels or 150# on the nose and 170# on the wheels?

How much weight is enough.? I refuse to pay $70+ for a piece of steel they call a weight kit.
I can't comment on your finances (although I there is a discussion and inflation, relative prices and gold standard that I just left) however enough weight to keep it down before the tire spins. The the question becomes how much is that.
Let's assume there are 200 lbf on the wheels. That pretty much defines it. The ratio is 200:1, the radius 8". even a little motor could generate that. It would be 130-150 ft-lb lifting the nose. If the skid shoes are 2' in front of the axle, that is 65-75 lb it becomes weightless. So, a total weight of 100lb or so should keep it down and 125lb should give it some bite. Note that pushing down on the handlebars or a cab on the handlebars also takes weight off the nose.

Wheelie bars don't move the pivot. They act like sticking out an arm to brace yourself has you are falling. As shown, the force raising the nose should be in the 75 pound range at the skid shoes, limited by rear wheel traction. If the nose is heavier, it will stay down.
Go ahead add 75-150 lbs.onto the front end of YOUR snowblower that would make turning fun. The bucket might support the weight but you'd be shaving the bottoms off the shoes of people living in China.
All the guy needs to do is buy a 25 lb. weight plate at Dicks Sporting Goods or Sports Authority and use a bunch of wire ties to hold it on the front of the bucket if he actually needs even that much weight. Dicks charges .89 cents a lb. for grip plates and if you go to a place that sells bodybuilding equipment you can buy a rubber coated weight plate for about $2 per lb. 75 lbs.of extra weight on the bucket is looney!

If two snowblowers had the same weight on the rear wheels, say 185#, but one had 90# on the skid shoes centered 22" from the axle and the other had 50# centered on the skid shoes centered 20" from the axle, which would be preferable? What if the one with 90# up front had 16" tires and the other had 15" tires? Can you draw a free body diagram showing where the flux decapitator is in relation to center of rotation of the nut behind the handlebars? Are the skid shoes plastic or metal? What's the torque on the nut behind the handlebars? How many times was that nut overtorqued? Are those tires all season tires? mounted on alloy rims or steel rims?
