Cyclone snow blowers?

How far does this onestage throw the snow? Two stage can have very impressive throw lengths if that is important.

I am unaware if Reist has done a tonnage per hour measurement with thier single stage units but all that amounts to is dumping a set tonnage of snow in front of the attachment and timing how long it takes for the snow blower or snow thrower to clear it per minute at 88 feet per minute (1 mile per hour); 176 feet per minute(2 miles per hour); 264 feet per minute(3 miles an hour).

Like any other snow blower or snow thrower the slower one travels the farther the snow and ice will be cast as the full torque delivered to the attachment will be transmitted to the snow blower rotor to spin the augers to deliver the smaller portion of snow and ice to the 4 paddles and then up and out of the chute and spout.

A snow blower or snow thrower on a tractor is a lot different than a walk behind snow blower in that it is being powered by a 540 RPM PTO gearbox or a 1000 RPM reducing gearbox from a larger farm tractor.

A large walk behind the the Yamaha 1028 or 1332 2 stage track drive units chop the snow in to the smallest proportion with the serrated cross augers before it is pushed in to the impeller housing by the forward motion of the snow blower when it advances into the snow pack where the snow ahead of it is pushing it into the cross auger housing and it is ejected by the 4 impeller paddles through the chute and spout.
The 1028 and the 1332 Yamahas have slick liner material that prevents the chute and spout from becoming clogged as all the material is thrown out at a very high velocity with the 4 blade impeller. The Yamaha folks have measured the tonnage moved per hour with their walk behind units and they move a lot of snow
The impeller of a 2 stage walk behind snow blower is powered directly by the engine through a linear drive shaft that connects with a spur and worm gear drive system that operates the cross augers which feed the snow into the impeller housing. The yamahas have the distinct advantage of heavy serrated cutting flights that break the ice and snow into smaller pieces allowing the snow to be conveyed to the impeller that much faster to be discharged.

Most snow engines are run at 3200 or 3500+- RPM and the 4 blade Impeller is V belt driven with one or two V belts in a reduction drive method through the drive pulleys and then the larger driven pulley which is the same size as the impeller diameter.
If the driven pulley was smaller it would force a stall and the belts would burn up.

One advantage of a pull behind is the fact that the surface area of the rear tires will compress the two bands of snow in front of the pull behind snow thrower and allow the snow blower rotor to pull the snow into the center of the rotor that much faster if it is a powder type snow.

The snow blower rotor on the single stage Reist snow throwers consists of a narrow flight ribbon that is 16 inches in outside diameter if I remember correctly and ribbon height is 3 inches in diameter allowing a total of 6 inches of ribbon flighting to convey the snow and ice to the center where the four paddles throw it up the chute and out of the spout to be discharged.

The center portion of the snow blower rotor has 4 paddles to eject the snow offset at 90 degree angles taking 4 bites per revolution so if the snow blower rotor was rotating a 600 RPM the 4 center paddles in the snow blower rotor would be rotating 2400 times per minute to discharge the snow that is being fed into the snow blower rotor as the tractor advances in to the snow pack.

With the open cross auger design the snow can be pushed forward creating a mountain of snwo that the snow blower still has to get through to clear an area where the single stage unit will not have that issue as any snow that is pulled in will be discharged in one revolution of the snow blower rotor without clogging.

Hi i have a 92" Normand inverted and this blower is my only experience. My question about single stage blowers is that the bearing get alot more abuse so how well do they hold up? I do not use a rear scraper with mine because I don't want to deal with it. I do however wish i could get closer to garage doors. I also think that the Normand i have mounts closer to the tractor so the blower has less leverage against the 3 point hitch. I have had a part break on the the 3 point so weight and distance away from tractor should be things to look at.

Hello and good morning graderguy.

The bearings for single stage bearings are the open flange mount type of single row ball bearings just like the single row ball bearings used for the flail mower rotor bearings. These single row ball bearings operate at one third the speed of the roller bearings used on flail mowers being 600 to 700 revolutions per minute.

These cast flange single row ball bearings are mounted on the outside of the side weldments of the single stage snow throwers and can easily be replaced on the carrier side as well as being greased.

The roller bearing on the driven side can be replaced by removing the roller chain, then remove the drive sprocket and the locking ring flange bushing and then remove the complete bearing flange and replace it with a new complete flange bearing.

Flange bearings last for years when operated under load. We replaced our first set of flail mower bearings probably 14 years ago on the flail mower I use and the flail mower I use is 37 years old.
