Guess what this Attex Prototype is for!

Ummm, looking at the pictures, I just noticed that there are no shifters in the T-20. It almost looks like the holes aren't completely bored out. What's up with that?

Didnt need reverse because you could reverse the electric motor.

I'm going to take a guess here Stonewall.......It looks like this machine is set up with split shifters, like you are doing on your Hustler. Every T-20 case is the same with those holes on both the top and bottom sides of the case, regardless of left or right side so they didn't have to have two different molds. They just bore out either the upper shifter holes or the lower shifter holes to for the T-20 case to be either the right or left side. They probably mounted the diamond shifters in this machine on the bottom side of the T-20 because of clearance issues.

~EDIT~ Never mind, Mr. Gerber beat me to it, haha.

Ah, thanks for the clarification... Now I feel like a dumbass...

It was an excellent guess, but I could see alot of leakage problems from doing that...

Very true......I didn't even think of that. Especially with just a single O-ring, and a not so tight fit of the diamond shifter and lots of back and forth motion on it from shifting.

It was probably reversed electrically so that T-20 may be a little different. The motor is an explosion proof type also due to gases in the mines. It also does not have a CVT set of clutches. Since electrical motors do not depend on RPM for torque they are not needed. Again these are my thoughts on the design.

Very cool pictures and i wounder if any of them have survived the years?

I will have to ask my father Howard on that one, I will get back to you!

Howard said they were built for mine rescues. There were originally plans to introduce a large number, but only one was ever built.
