Hydrostatic transmission hydro-gear
« on: May 01, 2022, 03:25:41 pm »
So iam doing a build which involves a standard hydro gear.
Let me firstly be clear that this is simply a fun project.

My snapper lt175 comes with a hydro gear which has an 8cc motor and a 10cc pump.
Firstly I want to swap the 10cc pump out with a 12 which should fit just fine.

Secondly I am swapping gears to get the reduction way down from 25:1 to about 21:1

Thirdly I am swapping the rear pulley from 5 to 4 inch.

Last but not least I will change the tire size from 18 to 22 inch.

So now I am wondering what is left to think about.
I know I am not going to make a speed demon but I want to be able to get the most out of this setup.
Anyone have tips to get the efficiency up? I also thought about perhaps adding an oil cooler to the transaxle for instance.

Any tips would be welcome.
