QA42A question

[smithm1979]

I've got a 1250 with the QA 42A snow blower attachment. The best it does is throw it about 4 feet but a lot of times it doesn't even clear the blower. I could even live with that but it gets clogged up a lot and that's with very little snow (less than 6"). Also, the snow has been generally on the dry side. I've sprayed the chute with both silicone lube and fluid film. I'm keeping the engine speed at max and going really slow on my ground speed. Could it be that the belt isn't tight enough and it's slipping a little? Getting pretty frustrated with it. My driveway's less than 100' long, slight-moderate hill and I have to unclog the chute at least 10 times per session.

Hello and welcome to OCC!
A person usually starts a new thread rather than reply to/ask a question of a 5 year old thread.
But you are new so it is ok.

Admin Note: Moved to proper location.


As far as your snow thrower not throwing snow far enough,and clogging that can be due to several things:
As mentioned, your belt has to be really tight.
You have to keep engine rpm's high-3600, check it with a tach, either borrow one or get a inexpensive mini one on evil bay.
Also, you have to adjust your forward speed to keep the thrower full of snow.
If you go too slow, it will just dribble out the chute.
it is best to keep the fwd motion so the engine has the governor wide open, and is producing max rpm's and fully loaded with snow, but slow your fwd speed, when you hear the engine begin loosing power.
Also I might add, wet snow is difficult to throw and will not throw as easily or as far as dry snow.
As an afterthought, is your thrower's driven pulley on the gear box the correct one or has it been changed by possibly a previous owner?
Oh and the guys here, like pictures.

Thanks for the quick response. I'll try those things and let you know. It seems counterintuitive to go faster but it does seem that the snow is more or less dribbling out.

Here's my 125 with a QA42 ( NF version of your thrower )

As stated, run it at WOT and keep the thrower loaded to get it to work best.

Ran the same thrower on a 127 for 20 seasons or more and never did put a new belt on it.
So I can't say for sure but if the belt were slipping I would think it would squeal, smell and then shred in one plow session. The rest of the drivetrain is all chains gears and shafts so those are all go or no go.

As stated above, engine speed full throttle and enough speed to give it enough snow to be able to throw good. Once you know it is throwing good you can always adjust throttle down to suit.

I do remember if trying to clear an inch or so it would just do what you describe.
The deep fluffy dry powder was the most fun to throw as long as you were throwing it down wind, LOL.

P.S. welcome to the forum!

Also make sure there is no rust on the chute, it needs to be bright and shiny. I was frustrated at first also years ago with the cw36 thrower on a 102 but got good advice on here how to make it work well. Cleaning up the chute and spraying silicone worked well. Have also cleaned up a few qa42s and got them to work nice. On your 1250 the exhaust dumps out in the front, it's helpful to get an elbow to divert it to prevent clogging in the chute
