I agree that if ain't broke, don't fix it but......

I have a Simplicity yard tractor, model 5216, that I purchased new in September, 1987. It has a 16 HP I/C Briggs engine and hydrostatic drive. I live in Central New York and use the tractor for lawnmowing and snowblowing. It gets a lot of use. I've not had any problems with this tractor but I have a couple of questions with regard to the hydrostatic drive.
1. Will this hydrostatic drive give any warnings when it is getting tired?
2. Should I pull it apart and replace any seals or other parts as a preventative maintenance measure.
I don't want it to go down unexpectedly but I don't want to mess with a good thing either.

Your thoughts are appreciated,

Hello Andy

About the only thing you should do is the preventative maintenance recommended in the owners manual. Changing fluids at least as often as required. More so during heavy work loads, hot weather and equipment age.

Attempting to do further preventative maintenance may prove to be counterproductive. You'll also have to verify if all the parts are available prior to making any repairs.

You'll also need the shop repair manual and any specialized tools prior to starting the task. Often times the unexpected happens during repairs and the machine becomes unuseable during part back orders. A few reasons why regular preventative maintenance is important.

There may not be any warning prior to a powerdrive failure. If you discover hard shifting or a lag going into gear or shifting, it may be one of the first signs of an impending drive failure.

If all is currently running fine since 1987, continue the regular maintenance work and don't don't fix it.

Bare in mind my company no longer services nor repairs lawn and garden powered equipment. Rest assured and fully confident, the help I offer you is based upon my prior years in this industry, with this type of equipment and is specific and accurate to the best of my knowledge...
