Build ideas??

I was wondering if anyone ever installed the int154 final drives on a cub cadet hydro?? I know that the normal high speed is pretty fast on the stock hydro to begin with. But if the added final drives make it too slow is there an adjustable flow valve that will increase the ground speed on the hydro tranny??

My thoughts are to fabricate a frame inbetween the cub cadet and int154 size wise and build a middle sized tractor thats a hydro using the cadet hydro tranny along with the 154 parts.

Bill, the finals will slow the rotation, about 10 to 1, but also reverse the direction. You''ll have 1 speed forward, 3 revere. I don't know if the differential is the same, on the hydros. In the manual ones, flipping the differential, corrects the rotation. Ed

My first attempt at Brutus was to use a 127/hydro. I put regular cub finals on the hydro tranny. It slowed the cadet down way too much. It is adding a 6-1 reduction to it. I changed to the 582 cub cadet with three speed model and took out the front gear reduction on the three speed tranny to overcome this problem.

Don't know about being able to change the flow.

You can go to this page and see what I did to remove the gear reduction in the front of the tranny.

Maybe changing the flow isn't needed if forward and reverse gets the same exact oil flow and ground speed? But forward will become reverse and reverse will be forward on the shift lever right? Using the 8,3x24 tires on it should bring back the ground speed on the hydro?

It would be a bit of machining work, but hypothetically, you could use the Cub final drives, but pull the gears out and install 1:1 sprockets with chain drives. Like I said, a bit of work, but structurally, everything should hold up and you would maintain the correct ground speed. Just a thought.
