Can't wait to try these things out with a bull this year. We have been testing them with 100 lb loads of dog food and they have performed flawlessly. We will be cranking the weight up to 200 lbs in the next week and see how they hold up. The way Tyson's cart hooks up is a one off design that may be the best idea for a cart hookup to a bike that I have seen. We are going to test it out this year and report back. Mine just connects to the seat post.

We have hauled out 10+ elk (whole elk with bone in quarters) on a lot heavier cart and we dont have problems going down most hills with the disk brakes. There are a few hills where I will just get off and walk down though. Nice thing about the trailer is it helps hold you up (like training wheels) and you can go up hills slower than you normally could.

We opted for the rectangular aluminum section rather than square. The same weight but 3 times stronger in bending and 2 times stronger in shear. We also added gussets to strengthen the connections and add some redundancy.
Never really looked at the Hawkeye built carts to closely, but they do look well built.

Materials:
$50 in aluminum (1.5" x .75" tubing 1/8" wall)
$80 in aluminum welding
$15 studded spherical ball end
$10 in 2" polypro strapping (www.strapworks.com (http://www.strapworks.com))
We cut all the pieces, chamfered all the edges, fit everything up, etc... We just had to have someone weld it.
As far as the open tires, we looked into welding cages around them but we wanted to keep the weight down and elected to try and use strapping to secure the load from shifting (We will see how that works).

Well, when it came to the design of the cart there are some things that just have to be the way they are. In order to use old bike wheels the dual beam sysem is required.

You don't need brakes on the trailer since you have disk brakes on your bike. Trust me. =) They would be nice, but they are an expensive hassle that we ended up sh$& canning in the end. When in doubt, throw 50 lbs. of meat on your back for the wet and steep downhill rides.
Nice cart. Hawkeye makes one just like that. I have an "older" Hawkeye that's a little bigger... It's hauled a lot of elk out for my buddy and I. We have used the Slime triple thick tires for years, and never a single flat.
Here's a pic of mine with an entire 5x5 and the pack frames. 14 miles back in your neck of the woods. =)

Slim9300 nice cart... If Hawkeye has a patent on the cart design you will be looking for trouble if you start selling them. There is just tooo many simularities between his and yours. The webbing is another he uses gill net for it and you use straps. Something to think about is if you picked up say 13 people from Seattle and they looked at these two carts in court would they say they look the same? I am just trying to help you out before you pull the trigger and start selling them.
I doubt there is a patent, but who knows. Should be very easy to look up. Wayne (the owner and retired logger) is a good guy that just did it out of his garage. I don't even think he builds them anymore.

As for a patent... So here is what I know from working in the High Tech industry. If you put an idea with an inferred design on the internet you can challenge someone who then patents it. The patent challenger has the right to prove they had the intellectual property prior to the patent requester or holder for that matter. If they have made any money associated within when it is challenged that money can be challenged as well in court.

Good lookin cart though! :tup:

I thought their names were Kent Hawkins and his son was Mike. But it was a long time ago when I met them at the Blacktail Country meeting some years ago so I might be wrong. I remember it because they gave one of their carts away in a raffle. And I did not win it. :dunno:

Lol. Maybe his name was Kent.
It was long time ago when I drove down to northern OR to his house and bought the cart.

As far as patent infringement, I didn't think you could have a patent on welding aluminum together in squares and triangles. Now I could see patents on the connection type or other things special about the cart. A patent is put on something "new", "non obvious", and "useful".
I called the guys up at Hawkeye Carts today. I believe I talked to Mike. We BS'd about the cart designs and the differences. We talked about the strength of the frames, different wheel sizes, connection types, etc... He said that they did have a patent on their connection type and a poor man's patent on something to do with the frame. I just use a studded spherical ball joint for 360* of rotation. It was a good conversation and I enjoy talking hunting with anyone and everyone. Afterall that's why we are all here, right? I hope he gets on here and comments on the carts, I am all ears.
My intention is not to steal anyones ideas. I am a stand-up guy and if the Hawkins guys' have the right to any part of the design I will do the right thing and talk to them before I ever pursue manufacturing these things.
Now time to go see how this thing does with 200 lbs.

Did you consider building with the same rims and tubes as your bikes? Easier to repair with less parts to carry...
