Default 450 Blower issues

I purchased a 450 snowblower for my 1811. Sorry that it's hard to read the Lot/model number & MFG date in the photo, it reads as follows: 190-450-100H298D. I removed all of the SGT mounting hardware, moved the brackets to the correct holes, and drilled the lifting straps so that everything mounted to my 1811. Took it for a test drive in the yard and it would only blow 5" of light snow about 6 feet at full throttle. The augers look like they're moving pretty slow as well. I knew it came off of a 1782. After contacting the PO, what I didn't know about the 1782 was that it has a larger 6" PTO. My 1811 has a 4.5" PTO (outside dia.). The pulley on the 450 snowblower is about 7 1/8 outside dia.

Not sure if I did this correctly or not... To get one full rotation of the blower fan, I have to turn the gear box pulley a little over 2.5 rotations. Sam Mac just posted in a different thread that the 450 gearbox is 1.86:1 and the 451 gear box is 2.58:1. Did Cub Cadet make a 450 with a different gear box for later model cubs? Is the 450 meant to attach to a 1782? Or did the PO swap the gear box with one from a 451? Is the pulley on the gear box of a 450 just over 7", or did the PO swap that out?

Is there anyway to fix this without spending a bunch of money for a new PTO that I'll have to swap out when I put the 44C mower deck back on? ...Guessing a smaller pulley on the snowblower???

Depends on the 1782's serial number.
This is for the 1782.

This is for the 1811.

But, I don't know chit either way about snowthrowers...
For some of your questions, seems the PO could answer a few of them for you. As long as you can talk to him, he'd know what he switched, or didn't.

I think you answered your own question. Pretty obvious that if you have a input to output ratio of 2.5:1 that it has a gearbox off of a 451.

Options are, sell that blower or trade it for a true 450, or change the PTO on the tractor. Switching pulleys isn't a good idea as you would have to go smaller. You will lose belt surface area and won't hold the load well. The 2 stage blowers take a lot of power to run.

The augers on the two stage throwers don't turn real fast, by the way.

Zippy1- Thanks for the info on cubs website for looking up attachments, I hadn't seen that yet. The 450 gear box assembly part numbers are the same for both the 1811 and 1782, pretty obvious. J-mech is correct the gear box must have been swapped somewhere along the way. The PO inherited the whole set up from his grandfather's estate, so I don't have much to go on for what was modified and what wasn't.

J-mech- Thank you for the insight on not going to a smaller pulley, that makes sense. I'll probably put this one on craigslist. Just confirming, the only difference between the 450 and 451 is the gear box ratio. I want to advertise this snowblower correctly.

Thanks!!

Yes, the only difference between the two models is the gearbox ratios. Otherwise they are identical implements.

It's not my ideal scenario, but I may have stumbled into the larger PTO locally that could fix my gear box issue. Does anyone know if a PTO off an 1864 (command) will fit my 1811 (magnum)? On the expanded view I got off cubs website, they're almost the exact same, the 1811 has a Drum,Brake (#4 ) and the 1864 does not.

1811:

Thanks!!

There is a number "1" stamped on the gearbox to differentiate the model 451 from the 450.

Gabe, Both PTO's will fit on either tractor. Both have one wire to the PTO, +12v. The ground is attached to the mounting plate. I had both on my 1541 with a M18. Those are the older style units. The newer style will fit as well, but it has a ground wire instead of grounding to the plate. I have this on my tractor now, Extreme Clutch.
I had the same issue with the 450/451 thrower. I got lucky and found someone who needed the 450 gears and traded my their 451 set. See this link. http://www.cubcadetcollectors.com/fo...php?f=8&t=6684

Frank, thank you for posting that article and your response. This has been a learning experience, with out question. So, just to confirm, this newer style PTO bolt to my Mag18?

Darkminion, do you know if you can see the 1 stamped into the gear box when it's mounted on the blower? Either way, after counting the pulley revolutions, I'm certain it's a 451 great box.

Thank you!

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.
