Narrow Frame PTO

I have a 104 and a qa42 thrower attachment, im sure many of you have come across this problem but when im using it there seems to be a fine line between the rpms and speed of plowing, i was curious if anyone has put a smaller pulley on the pto to make the blower spin faster but keep the tractor going slow enough, thanks

I am assuming this is a typo, and you meant "blowing" instead of plowing.

A gear drive tractor is better suited with a "creeper gear" attachment for using a Snowthrower.

However, people have sped up the snowthrower mechanism by installing a smaller pulley. As a word to the wise, make sure that all the snowthrower bearings are all good and in top notch shape before adding more RPM's.

I gotta agree with Roland, if you go speeding things up, everything better be in excellent condition, including all the parts in the gearbox and everything associated with the chain tensioner. It's a lot cheaper to rebuild these parts first rather than replace them after they explode.

Using a smaller pulley is also going to cost you some power, your 10 hp engine may not be able to handle the extra load.

If you don't have a creeper, I believe you're going to have a hard time throwing snow, your ground speed needs to be fast enough to keep the housing full of snow but not so fast that you end up pushing the snow.

As Sam said, and I agree 200%
A good 10 hp has a lot of work to do operating a 42" thrower.
You might speed it up a little but not accomplish anything as the engine will not be able to power it in the deeper stuff or wet slop.

I'll just throw this out here:
a thrower auger can be speeded up with a drive sprocket change of 1 tooth larger.
Again I don't recommend it because of the engine hp.
But in a different situation if a fellow has to replace a worn drive sprocket, that would be a good time to do it.
I'll not go into detail as to derail the thread, as I tend to do that too much.

Here is some more good readin about snow thrower modifications.

Thank you everyone maybe a 42" plow would better suit me? I have made a 80lb weight box and have chains on the rear tires

To each is own, they both have their advantages.
With a front mounted blade, sometimes ppl run out of places to push the frozen sunshine, with a thrower it gives you an added option, of throwing it into your neighbor's yard

Keep the forward speed so as the the governor is WFO as much as possible, but not so the engine is down on RPM's
After a bit a new operator learns the "tricks"
If it is windy with the snow in your face, a blade is more user friendly.
Don't blow snow facing the wind (or pee into the wind for that matter)

I gotta agree with George on all counts.

Throwin snow with your Cub is a little like playing a video game, it takes a little practice and every snow is a little different.

A gear drive Cub really does need a creeper gear. If you don't have a creeper, you can try taking less than a full width with each pass or throwing before it gets too deep. Some of the gear drive guys can help out here, but one can throw 4 inches or so of dry powder without a creeper (can't you?). Most important is to keep the thrower housing full but not overloaded.

Better yet, would be to find a 12, 14 or more hp tractor to put your thrower on and keep your 104 to use with a blade. Then you have all your bases covered, you can throw the dry snow or push the wet sloppy stuff.

Good Luck

Very very helpful guys i really appreciate it, thanks for the welcome and i agree with using a blade. Theres a nice one near
Me for $125 i could prob get for $100 and i can sell my thrower for $200, i love the 104 and it treats me great and i dont want to overload the 10hp or put too much strain on the bearings/u-joints of the thrower.

Gator I have a 102 with a creeper gear which is much like your 104. I used that tractor and a 36 inch snow blower for many years. I believe my 36 and your 42 inch are both single stage throwers. That little 10 horse engine is a real worker but in my experience without a creeper in any snow 4 inches deep or more my ground speed even in 1st gear was too much and the engine would bog down. When I used the creeper I could blow snow till it actually pushed over the top of the blower without bogging down. My 36 inch auger already spins and a really good speed and I would not consider making it any faster. The creeper comes with its own unique operating characteristics. When using the creeper you should not change tranny gears so if you are in a forward gear and want to back up you must first shift the creeper to high and then switch the tranny from forward to reverse. If your tractor does not have a creeper in it now you will also need to replace the driveshaft with the proper shorter one.
