    I too have spent considerable time on-line to first identify and then troubleshoot the hydros and the problems. My machine appears to have the Murray hydros with the external gear cog. I have not found a number on either case, but have not removed these drives yet. My findings, based on my...

    Whew! Nice talk. Just to clarify, “..making holes everywhere” was actually one hole each in the bottom of the drives, to create a 1/8 NPT drain. The holes were drilled carefully with the cases full of oil still (as the only way to change the oil is to remove the drives and invert to drain...

    I have been performing DIY small equipment repair and maintenance for many years, but have no experience with hydro-static drive transaxels until now. I recently picked up a Craftsman ZT7000 with a Kohler 20HP drive. The engine runs great, but I’m experiencing serious and uncontrollable lurching...

    Water in the fuel

    I can't be alone when I complain of a constant problem with water accumulating in my gas engine tanks. I'm aware of the problem caused by the alcohol content in our gasoline absorbing humidity and condensing water, but I have been searching for some time for a small engine version of the water...
