Do new machines move/throw more snow than old?

I have a 1998 Yard Machine 10HP 28 in snowblower. The thing is running a little rough right now, but I'm trying to "tune it up". It runs great when under load. In fact, you can't hardly bog that engine down, it just keeps going. Seems like the limitation is how much snow it clears. The auger area seems to fill up fast and it can't throw the snow away fast enough and it either pushes it or falls out the sides. I was looking at new machines, such as a Toro Power Max 928 OAE 28 in with 265cc engine. The engine is actually a smaller cc engine than what I have, but I was wondering if these new machines are able to more efficiently throw snow and would this actually be an upgrade from what I have? It would be disappointing if I upgraded to find the newer machine wasn't much of an improvement. And the smaller cc engine worries me. Opinions?

New machines spin faster with higher torque engines. I think better pulley ratios help also. My Husqvarna throws water and slush 30ft. My old noma would just clog right away

To me the answer on whether new machines work better is yes and no. Some do, some don't, then again you have add in the condition and tune of the older units you're comparing it to.
I know I'm generalizing but most of the older machines have thicker metal in them. The have less plastic in them also. Most will have metal bushings also. One big one for me is the cast iron engines vs alloy/sleeved engines found on the newer units.
As far as moving snow, that's a function of the impeller and the augers feeding them in addition to the general condition of the blower. One additional thing is the newer one have concessions made to them for the epa, some say it kills or hurts performance in some cases.

This is one of those "it depends" questions. Pick what you want and go for it.

Most new machines are OHV instead of the older L-Head engines. OHVs have more torque at the same HP than an L-Head. So just because its the same cc doesn't mean it isn't more powerful (torque) which is what you want for snow.

HP = the rate at witch work is done. Torque = a twisting force that tends to cause rotation.
Cars are marketed in HP - top speed. Trucks are marketed for torque - ability to tow/haul.

Modern impeller and chute designs seem to increase throwing distance and handle slush better.

My '91 Ariens Pro seems to drastically outperform the newer machines in my neighborhood, but they are all entry and mid range units from various manufacturers. I'm curious to see how a new pro level machine would match up.

Depending on your machine you might be able to find a bigger upper pulley to increase the impeller and auger rpm.

That or an impeller kit may be worth looking into before spending money on a new machine

A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

My old 30 year Honda HS80 throws as well as new since we installed impeller kit.

The regular Ariens Platinum spins the impeller at 1010 rpm while the SHO spins it at 1083 rpm. The 14" impeller tip speed is 61.7 ft/sec on regular Platinum and 66.2 ft/sec on the SHO models.

My '91 Ariens ST1232 impeller spins at 1200rpm - 3" drive pully @ 3600rpm to a 9" impeller pulley - with an impeller kit at 14.5" diameter - giving it a tip speed of 75.9 ft/sec.

This is a 6 blade impeller though. New machines have 3 blades. Not sure if the higher speed is because each fan is moving less snow than the 3 blade impellers.

I'm not sure of the impeller and tip speed on older machines with 12" impellers, but the older machines with 14" impellers and 6 blades spin faster than the new machines.

My machine throws snow 70' in perfect conditions, but only advertised at 5'-35' in the manual. Had snow landing at the foot of tree 70' from edge of driveway once - wasn't windy that day.

New machines market 3'-60' for Pro models. I wonder how far it throws in perfect conditions, to the moon?

I had to adjust where I throw when I bought my new blower, almost took out the neighbors windows

I have a 1996 10/30 Yardman with the impeller mod. Do the impeller mod and get some heated gloves. You now have lots left over for beer.
