I used to collect vacuums when I was younger but sold them all when I wanted to buy a car. Still have a little interest in them whenever I come across them. I have 11 NIB, unused, unassembled green Bison Mark I machines for sale. Some of the boxes show some minor wear, but everything inside the box is undamaged.

I'm asking $500 for each machine, plus whatever it costs to send it to you. Professional packing by UPS costs $60 ($30 for a box, $30 for the packing.) These are big & heavy and will be expensive to ship depending where you live. I have shipped one of these to MI and ground shipping was $90, so you can use that to get an idea of how much it will cost to ship to where you live. For any interested buyers, I will have to have the machine packed first so we can figure out how much the shipping cost will be. After I message you with the total cost and receive a cleared payment, it will be shipped out. I will only accept Paypal, and I will only ship to the US or Canada.

Did they actually clean well? One has to wonder seeing how many are left NIB. I understand the company tanked, but this seems to be a ridiculous amount of unused cleaners left.

I've got a Centurion and it really does clean well. Although bulky and unwieldy it does have a lot of power.

That sounds tempting as hell & I still remember how to fix those too! I know the plastic can be very brittle & will snap fairly easy.

You are most welcome! Marks_here, you are correct, the plastic does get brittle much like the neck and handle assembly on a Hoover Innovation but if you are gentle with it breakage shouldn't ever happen. I suppose the reason so many of these broke easily was because the average consumer would just bang it around and manhandle it. From what I hear the assembly that connects the brush roll drive to the fan shaft would strip out often. Luckily, if anyone would like a spare drive assembly I came across a few NOS ones at the old vacuum shop along with an NOS brushroll.

I am with Bvac6-A NIB Bison would be interesting-but too expensive for me,too.The Sew&Vac man here has only seen one-needed a belt.I would be concerned about shipping these-the fragile plastic motor case-would have to be REALLY well packed to withstand the shippers baggage smasher gorilla!

The motor housing plastic became brittle when it reacted with the petroleum from the grease that leaked out of the power take off gear case. I had a NIB Bison that was given to me many years ago, it sat in the box in a cool dry place when I opened it the entire green case was cracked, when I investigated it, I found some grease liquefied and dripped out of the gear case onto the plastic and when you touched it, it just crumbled, what a shame. It is amazing what petroleum based lubricants can do to plastic.

Was at my favorite vacuum shop in town today grabbing some belts. Been years since I was last in there. The guy is a big time collector and has hundreds and hundreds of old machines.

He told me today of the two new in box bisons he has. One green and one hammer tone. When he bought the hammer tone one his friend was demonstrating it in his shop. He plugged the machine in not knowing it was on and the knob turned all the way up. The machine took off across the floor and slammed into the wall knocking off the nozzle and breaking the housing apart. Pretty insane

Would be nice to add to my collection.

I've been in contact with the seller. However, between UPS packing and shipping costs its another $150.00 in additional costs for one of these Bison's. I just can't justify $650.00 for a vacuum that's just going to be on display. I believe this 1975 model Bison was being marketed at the same time the Kirby Omega model was introduced. The new Omega was selling between $475.00 and $525.00 depending on how much the salesmen could get you to actually spend. I'm still happy with my NIB Bison Centurion I bought from Taranchula Arms a few years ago for $300.00

I'm sure I'll eventually find a green Bison at a reasonable price to add to my collection.

Bison 's cleaning ability..

They really were powerful and probably would out clean anything on the market at the time, the problem was they often broke down on the demo!!!! This info comes from Clay Floyd who was a dealer, he said he went to a Bison meeting and the owner of the company locked them in a room and proceeded to preach a sermon to them, then told them he better never hear of HIS Bison being sold to black people or in a trailer park!!Its no wonder the company didn't last!!

On those machines being sold-If you were to buy one-hoped it is packed WELL so the delicate plastic motor housing isn't broken during shipment.If I were a salesman-Wouldn't care WHO I sold the machine too-if they have the money or credit,really WANT the machine-CLOSE THE SALE!!!that manager is an IDIOT-If he worked under me I would FIRE him!

Hans, I've heard that story before. I think remember Clay telling that story at the St. Louis VCCC convention in 06. That's terrible lol

What do you think one of these Bisons are worth.

kirbyguy's profile picture
I'm just curious as to what you think would be a reasonable offer to make on one of these NIB Bison's. The seller is stating these are NIB however, the machines have not been tested and are being sold as is. I'' hesitant in spending several hundred dollars on a vacuum that may arrive DOA or in pieces. Especially since parts are very difficult to find, if they can even be found any longer. I can do repairs and rebuilds on my Kirby's. But I'm not sure how difficult a Bison is to work on in so far as any major repairs.

Would appreciate any feedback.

No wonder why Bison went down-an owner that stupid.Sounds like they could have had a nice machine-but the owner made some dumb mistakes.Kinda sad.

I bit the bullet and contacted this seller and bought one of these beauties!!!! Holy cow where is the positive feedback button lol I'm VERY pleased. Everything was new and in PERFECT condition and the shipping was fast and packing was superb! If I had the money I'd buy all 11 of them. I just thought I'd share how pleased I was with my purchase

My new vacuum room is still underway, as soon as it's finished I will get all of my collection out of boxes and display. I'm going to leave this in the box as well until then. When room is finished I will display it assembled but only to play with for mini meets.

I wish i have a bison. I saw yours on eBay that is now up to $895. Yikes!

Post# 381530 , Reply# 23   11/18/2017 at 06:47 by tolivac (Greenville,NC)        

No wonder they are still around-thought they were trying to sell these awhile ago-yes,I would like one,too but don't want to pay that kind of price-I don't want a Bison THAT badly.And would its fragile plastic motor housing survive shipping-it will have to endure the shipping service baggage smasher gorillas!

zero bidders

The NIB Bison on Ebay was listed at $895, but had no bidders. Perhaps a weeee bit high.

My Bison Mark II and Thread Number 25205

phaeton's profile picture
Hello All,
I have the Mark II Bison and while it has a massive amount of power it is a deafening experience to use. I had to replace the belt which was beyond a ridiculous experience. If I ever wanted to buy one again, I do still have my Mark II, I would only buy the Mark III as it has a front opening which allows for easy replacement of the belt and access to the pulley to hook the belt on.
There is a Thread No. 25205 The Bison which is good reading and the last Post shows my replacing the belt on My Mark II. I still have a number of unanswered questions on that Post regarding the Mark I, Mark II and Mark III.
I paid very little for my Bison Mark II and I did a minor repair to it which can be seen on the aforementioned, I just always liked that word, Thread. It was not used much and is still shinny but the bag is a bit faded. As a novelty to own I think it is okay, but to use it is a massive monster. My Omega is easy to use as is my D50 which might be even easier.
As far as novelty goes, my vintage Montgomery Ward with the push down handle release beats out the Bison any day.
I donít mean to offend anyone owning a Bison or selling a Bison and these are only my opinions.
Thank you for looking,

Are any these new machines still available?

Post# 382735 , Reply# 27   12/16/2017 at 10:44 by Power-Thrifter (WA)        

Yes, I still have a few available. Best way to contact me is by email as this is the first time I've logged on here in over a year.

For the people leaving negative comments regarding my price on eBay, notice how the machine sold for what I was asking.

That is a sad tidbit and indicative of people who think they can control race/gender/sexual orientation issues. I can only hope he goes out screaming.

If you had any other models other than mark II I'd think about biting the bullet again.

I just love mine that I bought from you! It's one of the top contenders for vacuuming my vintage new old stock wool deep shag carpeting. I only use it to play with as I want to keep it in new condition but using it in there in no problem as the shag in in the mini meet room and sees no traffic or pets.
