I hate those things, makes service a nightmare . Got a couple with little windows, but they don't stay on, and like you fellers a couple have been cut on with a dull knife by an fat angry midddle aged farmer with grease all over everything .
How about that dang metal guard that sits over the PTO shaft on some of the newer tractors. I probably shouldn't say this but I take that thing off as soon as it gets to the shop. I mean its right in the way. You can't see to put the shaft on - especially if its got one of those plastic guards on it. Now I fear and respect the PTO so don't get me wrong but some of this stuff is ridiculus. I have a simple rule. If the PTO is running I better not catch anyone including myself past the rear tire. No ifs ands or buts. I've seen what it can do and its serious business but it ain't gonna reach out 4 feet and getcha. JMO
