Hydrostatic transaxle problems
Had to replace the (separate) hydrostatic trans axles on my rider - the type with 2 levers that control steering and propulsion.
Put the new ones in, checked to make sure proper fluid level, but one of them has a problem.
Loses some of it's power and much of it's ground speed after it's been driven a short distance i.e. 100 yards or so. Does seem to retain most of it's propulsion power at slow speeds but definitely loses most of it at over about 1/3rd travel speed. Just in forward, reverse seems to be OK.
I've read where heavier oil can help, will try that today.
Took the bottom off the old one to see if anything looked like an adjustment of some type, but nothing really obvious.
I have quite a bit of wrenching experience, just not much inside hydrostatic units.
Had bought the transaxles last year when I thought I had a bad one but didn't (low fluid - have to pull the entire drive subframe out of the mower to check it) and now I can't even get an answer from the vendor, the distribution center that shipped it, or the manufacturer, regarding any possible solutions other than replacement.
I'm going to take another look inside th old one just in case.
Any possible tips other than heavier oil (and replacing the new one with another new one) will be appreciated.
