I hear tell of a second KT-7
Ok, please "tell" more. You did let the cat (snow) out of the bag per se

it was in a box
Well here are a lot of assumptions but.
Assuming the engine is at 2800 rpm
And the hydro motor is the same cubic as the pump then at wide open you would get the same as the engine input 2800 rpms now the next assumption comes from a picture only of the right angle drive looks to be of bevel gear design I'm guessing 5 to 1 ratio then the next reduction comes from the clam shells. Next assumption comes from a picture counting teeth best I can looks to be double reduction of about 2.3 to 1 then the pitch of the sprocket comes from when Al had a square next to his belts looks like 6" and six pitches on the sprocket so with all that here goes
2800 divided by 5 ( right angle )=560 divided by clam shell 2.3 =244 sprocket
Rpms per minute 36" ( 6 pitches per rev ) 244x 36"=8784" per minute divided by 12 to get ft per minute = 732 x 60 minutes per hour =43920 divided by 5280
Feet per mile = 8.31 miles per hour
That's is rough without absolute verification
So to get more speed you need more rpms
Looking at the hydro page it does say 4000 rpm on the pump/motor combo
So let's use that in the equation and see what that would do.
That would give you 11.7 mph and have more power because of the higher rpm
Area that I would recommend to check. Would be where the arms come out of the pump make sure you have full travel of these with the cable controls this will affect the speed normal travel is about 20-22.5 degrees off center
The next area you could get more rpm would be the hydro motor its self it would
Need to be the adjustable kind like the skid steers used I believe it would just bolt on. Not sure if you have enough torque if you tried to reduce at the swash plate to half the displacement but you could reduce some and maybe get It to 15mph
But I think even at the 11.7 is not terrible
Hope this all helps
I hear tell of a second KT-7
After the short spin in the driveway at Big Als seeing the full stick ahead I think your really spot on. I hope to know for sure next Wens.
One looks to be the drive live brake but where's the disk? Al had one made or both but I don't see them in the picture ?
The other is the bypass we've been talking about for towing . Al thought that was the high speed function
If you look at this picture I think what was originally engineered was not to pull up but to take the bar and flip it down to make it bypass but I'm thinking Al changed it because of access limitations
Any idea what type of fluid Al used ?
I succumed to the grease God's and went to Amazon.com to buy an electric Milwaukee grease gun. I figure I don't want to spend my time pumping that handle. Oh the joy of a vintage Tucker I had better not complain.
