The deck is not thicker because it is built to hang off the side of your FEL while it is up in the air. Too much weight that high up in the air is not a good idea.
Duerwood, Do you have any pictures of the blades? And the fastening method, are they easily replaced/sharpened?
First off - glad to have your aboard and THANK YOU for the information. This is excellent and nice to see someone trying to start a business then taking the time to address questions and concerns!
I do like your idea a LOT and think you are off to a great start on the units. Have you given any thought to making one for a Mini Ex. Basically instead of the QD plate and assembly just have a "box" over the motor with the Mini ex bracket (Quick connect) mounts. Yours would make a great "home owner" or farmer type of mini ex unit for trimming brush along the road and such. Don't need a double extra heavy duty commercial machine for around the house/farm and this would really fit the build for a reasonable price.
Duerwood, thanks for the blade and carrier picture. One of the questions I asked you about in a phone conversation was will the hydraulic motor run in either direction, I don't remember the answer? lt190b
I can see a huge benefit in cutting tree branches on wood roads, atv/snowmobile trails, but to run this model, probably a 40 hp tractor should be used. For a tractor 25-35 hp, a smaller version somewhere around 2-300 lb. with 25-30" cutter would be better. For my tractor I'd be comfortable with 300 lb hanging off my loader. I do like the color tho, wonder what tractor that matches.
