Hi, What is the best way or process to change the hydrostatic pump seal on a 743B, Ser# 5093xxxxx, can't remember rest of #. Drips and leaks quite a bit of fluid. Would Tractor Supply Co. Trans/hydralic fluid work to refill? Thanks in advance

Here's a link to where I uploaded the section of the repair manual for your pump.

The trans/hydraulic oil is fine for use in your machine.
Are you talking about the seal on the input shaft at the back of the pump? engine side?
If so, i did this two weekends ago. It took me about 3 hours to remove the engine, change the seal, mess with the U-joints and start installing the engine again. Its very simple.
