I would mount the blower on MUCH thicker angle irons! --- just for safety reasons! otherwise you did a great job on it!
Can anyone identify this blower?

I wasn't thinking about impeller speeds but I looked closer at the TK machine and it has a 15" polly impeller, and it spins at 3,000 RPM per there specs. My snow blower has a 24" fabricated impeller and it spins at 540 RPM/ direct thru a gear box. You may want to review your impeller speed with the approx. 30" impeller. Looks like you are going direct no reduction with the engine connection.
Well, it worked great for awhile, then I noticed that the fan blade welds were cracking at the hub. Not good, and new fans of the correct size are pretty expensive. So, back to Craigslist and found this gem. No information on it can be found for this model anywhere. Speculating it was built in the late '80's to early '90's by Atwater-Strong Co. As you can see, it's PTO driven but that won't work for me. Here's the question: Would you self-power it and make it towable with an ATV or lawn tractor, or just rob one of the fans for my little DIY blower?

Double speed increase pulleys. How fast do the fans turn at full PTO speed? Would it be close enough you can run it with the engine from your other unit?
To replace the coupler you could flip the pulleys on the jack shaft to decrease engine RPM, then flip the pulleys at the fan end to bring it back up to engine speed. Would give double isolation between the fans and the engine, albeit at some sacrifice of horsepower. Just a thought...

In the video, I guesstimated the tractor PTO was turning about 175 r/m. I did all the pulley math and it came out as: 540 r/m input speed = 2,200 r/m impeller speed, but the HP requirement is unknown. The model is a PTO 25, so I'm assuming it means 25 HP? It weighs at least 400 lbs. Like you, I thought about the pulley swap. The PTO shaft is 1-1/2", and the idler and blower shafts are 1-1/4". The swap would be easy to do on paper because all the pulleys are Woods brand with interchangeable hubs, but would require dismantling half of the rusted solid machine. If I were to leave the pulleys alone and just put a 14" pulley on the PTO, belted to a small engine. it would look like the pic.
Right now I'm attempting to remove the rear impeller. It's aluminum frozen to a steel Woods hub. It may fit well in my other blower.
