Hi, . . my JD-3520-Cab,..has a cloth seat. It is sort of a multi colour "tan" which looks good, hides the general dust and dirt and with the seat being extremely well sprung, (adjustable spring to your weight and bounce),...I'm extremely happy with it winter and summer.
The JD mechanic has been in and out a few times and thus far, no signs of dirt and grease. Although they "know" this is my Rolls and are careful.
I vacuum out the cab at least once a year and the seat still looks good with over 950 hours but then again, "I" am the "only" operator. (same with my truck).
I think it's safe to say that I prefer the cloth seat.
CHEERS!

PS: ...I never thought of a "seat-cover",..but now that it has been mentioned, I will either make or buy one very soon,...great idea! I have a goodly skin of Elk-hyde left over from having custom cowboy boots made, that would fit, breath and look good! I would put the rough side out as there is nothing,..."nothing",... softer nor more luxurious than elk!! Thanks.
