Apparently have a transaxle/transmission problem ( the mower just stopped while mowing, and promptly the belt started binding/smoking...it's as if the transaxle just froze up).....have replaced the belt and adjusted brake/clutch.....mechanically everything looks solid and adjusted properly....have taken the transaxle apart.....immediately noticed that the lever that slides along the collared shaft looked to be jammed....also noticed a combination of 2 distinct colors of grease within the casing: orangish and the other blackish/brownish.....have cleaned out most of the old grease, but did NOT soak/clean the gears (the grease on them seemed clean enough not to disturb)....then filled the resevoirs with a 80-90 gear oil (right or wrong?)..and reassembled....everything seems to be rotating and working now, but seems to require excessive force to rotate the external top pulley and the corresponding internal gears.

My questions: should everthing rotate freely without alot of resistance, or is it normal for a fair amount of force be required....... is it possible that the excessive resistance is due to the old grease on the internal gears, and that cleaning them would be the solution.......does it need to be in any particular gear (or neutral) while checking......and finally, should I be using the 80-90 gear oil, or something else....it most definitely is more liquid than wha t I found inside, which was more like chocolate pudding.

THe transaxle is a Peerless, on an old Murray 30" riding lawnmower..model #309029x92B .

Thanks for any comments or other suggestions !

You should be able to turn the pulley on top of the tranny fairly easily will going through all the gear. Now the higher gears will turn harder, but should be fairly easy to do while the tranny is laying on the bench. Some of the Peerless units used gear oil and some use bentinite grease, which sounds like is what was in your tranny. with the tranny in neutral you should be able to spin the gears with almost no resistance.

If the gears are turning hard, that is what is causing your problems. find what is causing it and then you can repair it from their.

Thanks for your thoughts and advice....really appreciate the time...thanks!

Fact is, the gears are turning hard..do you think it's because of the old grease (which still looks good), or any other suggestions what to check for....PS....nothing looks broken.

Thanks! robrob
