I suspect those of us who don't wax, vs those of you that do, may use our machines in significantly different ways. Thus the difference.
I bought mine to
work. And in my discussions with my dealer (who sells mainly to farmers) told me in no uncertain terms "don't wash this like your car. There are too many places for water to infiltrate components where it shouldn't be. And, if you do wash it, make sure it's running at the time. The best thing you can do is take a leaf blower and remove the dust and dirt, clean your air filter daily, and perform scheduled maintenance". (It's in quotes, because he got in my face when he said it

)
I have pressure washed the undercarriage after working in mud, but try very hard not to pressure wash the engine. And I leave the excess grease around the fittings and FEL pins to seal out more dirt infiltrating the pins. I've had to remove them a couple of times, to clean out the grease channel and it's no fun.
I keep it garaged whenever it's not in use.
So if you're 5' away, it's not a show piece. It's a workhorse. But from 50' it looks fine. ( just like me! )
I envy all of you guys who wash and wax yours at will. I do my vehicles regularly, but I don't go 4-wheeling with them, or pull trailers thru the fields, or work them at all really. My tractor isn't a vehicle to me. It's a tool.
To each his own. :drink:
