Great reading Kraig! Now you really have my gears grinding... I initially noticed the leak after I changed the fluids and ran it for a while. It initially seemed to be coming from the filter. I tightened the filter thinking this was the source of my problem. Obviously it wasn't. I am now thinking it may be the cork gasket??? It seems that I am going to have to trace it back to the source. I may just keep an eye on my fluid and add fluid throughout this mowing season. I already have a list of other projects scheduled for next winter. Why not add 1 more... I will just have to use the shovel again next winter. I guess it's good for the back.
