Hi all, I just purchased a what I believe to be later model 28" rear rider. This is to replace the Snapper 21 walk behind that has served me for decades. When doing a once over and changing the oil I noticed that the rear wheel hub cap on the left side was clean as can be and the right side was full of grease. I believe this is the side with the transfer case and was wondering if this is normal as part of the lubrication process. It does look to be heavy grease and not the 00 stuff. Or is this a typical seal failure. Found two grease fittings on the front wheels, any other ones hidden that I should know about. Thanks, and I look forward to reading here as much as possible.
