Snapper Z1804K with a Koehler 18 15hp engine left rear tire drives only put new unit on right rear. Still won't work

Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!

What part did you replace? The hydrostat or the gear box? Hydrostat has to drive the gearbox, if it does, gear box may have broken gear.??

Gear box on right rear by the tire

Still won't drive that tire

Is the hydrostat driving the gearbox?

Customer: replied 1 month ago.
I guess left works right dosnt.

Is the connection between hydrostat and gearbox good?

Customer: replied 1 month ago.
What do you mean there is no leaks

How did it connect? Keyway or spline?

Customer: replied 1 month ago.
Not sure a nother guy put it together now they want me to figure out why its not working

Got to love it! Looks to me you need to slip the gear box off ans check the hydrostat.
