Default QA 42 speed
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
Tony

I get mine from McMaster.com. It's a pretty generic pulley I'm sure you could get one locally also. I tried three sizes before I settled on the current one. In light snow I actually slow the engine down a tad that's how good it works now. Of course I've got 16hp so I can fill the thrower better than you'll be able to. From what I've seen the fuller the thrower is the farther it will throw it.

All come furnished with a set screw.

Cast Iron

Pitch Diameter for Type A V-Belt 3.4"
Pitch Diameter for Type B V-Belt 3.8"

this is the pulley i run on my 1650 works great. i guess its actually 3.4" diameter for our application. get a good tough belt and run tight as you can get it and your in business!

i believe i had to go 1" shorter on the belt but i didn't write the number down sorry.

I didn't want to post this twice in the same thread but here ya go!

i did measure my pulley and it is the 4.5 outside dia assuming stock pulley
I looked on McMaster-Carr's sight ans found the number you suggested what confuses me is the number you gave shows a 4.15 outside dia is this right if i have a 4.5?
also i don't understand the pitch dia for type A and B belts how is this measured?
If you don't mind me asking what other sizes did you try? and do you think going a bit smaller with the lower HP is good or not?
Muzzy how often do you have to reapply the pb blaster? just once per use or mid way through?
Tony

Same here got this one late in the season last year didn't do a thing to it just put it on the tractor had some issues the little i did get to use it
took it all apart this summer sanded it painted with graphite paint augger and body replace bergs and chain hoping for the best and did get out of it what i thought i should.
not sure if the blower is just to big for the engine size or what.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
