QA42A Speed

[gmbadgley]

Does anyone know what the ratios are supposed to be?
I have a 1/1 between the Engine and angle box and 2/1 from the box to impeller. So if the engine is at 3000 RPM the impeller is at 1500. I am not happy with the performance of it at all. It is on a 1450 and a back up to my Toro 2 stage walk behind, but it only seems to throw a few feet. The pto & belt do not appear to be slipping so that leaves about one thing left - speed.

I seem to remember someone somewhere talking about changing pulley around for more speed. Any thoughts?

They were originally designed for an engine speed of 3600 rpm.

3000 rpm is only 83% of recommended engine speed.

Also, what type of snow? Slush/wet doesn't throw far.

I run a 3.8" pulley on mine works great. I think original pulley was 4.5". What size pulley is on your thrower?

Also paint ez slide on chute and inside thrower housing will help

I haven't measured the diameter, I just marked them to find the ratio.

The snow here so far has been slush (nothing throws that) and lake effect, the type of stuff that you can blow 30' with a leaf blower. I know it is only a single stage blower and by design the Toro should always out throw it, But I feel the unit should throw more than a few feet.

Mine throws wet heavy snow 10-20 ft and light snow about twice as far. With the 3.8" pulley. If you want to try one I can look up the part number for you. Also need 3600+ rpm or you won't throw well either

I'd be interested in a part # on this, too. And a belt size, too as the stock belt would be too big?

I don't want to beat a dead horse but also don't want to start a new thread.
I also have a QA42 on a 129 seems like all i have been getting since i got this was wet snow.
The past summer disassm cleaned and panted the auger shoot and insdie of body with a graphite paint.
First show of the year wet but shoot blocked up first and it actuly stoped the auger it's self.
Am i doing something wrong? I can not believe this thrower is this prone to stoppage as much as it has been.
Thinking of doing the pulley upgrade but just wanted you're guys thought that have been using them more then i have.
Please help with any help i'm thinking i made a big mistake buying the thrower now
Thanks
Tony

If your plugging up and you already painted the chute order the pulley i mentioned in a previous post and buy/borrow a tachometer to get your Rpms up to 3600-3800. Make sure your governor is set right. If that still doesn't do it try taking a smaller swat and drive faster! You need to work that 12 horse pretty hard to get wet snow to throw good! But it will do it if set up right!

I just used my qa36 for the first time today. It's on a 123 and I was impressed as to how well it threw the snow. The snow was wet and had sleet mixed in but, it threw it really good. I used pb blaster dry lube on the chute and that worked good too. I do have a problem with the belt tension screw though. Had to tighten the belt a few times.

Thank you John
I am a mechanic by trade and have a multimeter with the tach setting at work and plan on bringing it home and checking the RPM's out after seeing your prior post.
I just have a hard time believing that i am the only one that has ever tried to blow wet snow with this setup and as good as these tractors and other attachments work with the tractors can see the snowthrower being it's down fall.
Where do you get the pulley mentioned? Do one of the sponsors carry them?
Thanks Again
