Rotary Cutter Hydraulically Driven Tree Cutting Saws

[Bill Hall]

Is anyone aware of a hydraulically driven tree saw for cutting cedar, shrub or other small trees that was made in 2003 or earlier? In particular, any such machines that used an overhung load adapter.

If so, I would appreciate any information on such a machine.


Thanks

Thanks - I'm looking for something that would use a circular blade with an overhung load adapter or bearing block between the blade and the hydraulic motor. I've seen similar machines after 2003, was trying to find an example prior to that date.

In Oklahoma, I've seen advertisements for a Myers Cedar Tree Cutting machine but can't tell from the picture if it uses this adaptor to manage blade vibrations.

Look at these.

Look at these.

Thanks - any chance you know the date for any of the photos? The date is key to me as I'm trying to demonstrate these devices were known at least as early as 2003 preferably 2002 or earlier.

Thanks - yep, I have that linked book marked. Problem is I need the original URL. Those I do have like Circle 3 Welding, only go back to 2005 or so.

Ok, can't resist. Are you working on behalf of a plaintiff, defendant or doing some sort of due diligence for an inventor?

If only I could get paid to spend time on TBN, well...life would be good!!

If there is more info you can share, the more the better...and I promise I won't charge for my research - unless you are willing to pay!!

Feller bunchers used similar setups prior to Williams' patent.

Nice observation. For obvious reasons I can't go into detail. I can say that we do not represent a plaintiff looking to sue anyone.

As the son of a farm boy, I recognized early on that farmers are the original engineers. They can fix anything with stuff laying around in the shop. If they need a tool for a particular job, they more often than not build it.

I also know that local machine shops in rural areas are great at designing practical tools that fill unique needs. So, I'm hoping to discover treesaws made and sold by such shops.

It sort of hints at patent infringement tights. Who is copying who"s products.

If the farmer did make it, and did not patent it, does he still have the right to make more of the same product.

I would like to go into details; however, there are so many potential issues involved that I just can't. (Client issues and the general advice of most bar associations against giving legal advice on forums.)

Additionally, the recently passed America Invents Act will be bringing about changes that may impact the answer to your question. If you're interested about the new patent act, more information can be found here:

America Invents Act of 2011

Forums such as this provide very valuable advice to practical users and valuable prior art to patent attorneys. I greatly appreciate all the input received and interest in the project. Perhaps once the project is wrapped up, I'll be able to post more information.
