Haven't checked mine in a while...should probably do that, as the ol girl's getting on in age -- now at 1140 hrs. (Hey Ray -- STILL with the original battery!)
Did finally drop the MMM off, put that away and got the blower out, but still have the FEL on -- much better for dealing with the --again-- 3" of heavy wet, slushy crap that we got overnight and early this AM. Hope it's done now!
I also bit the bullet and ordered two rear wheels --just the rubber tire/wheel, mind you-- for the MMM. Mine are worn down to being flat across the rolling surface and only about 4" in diameter now, but wow, they want $155 EACH for those suckers! Even the parts guy at the dealership said he couldn't figure out where MF gets their prices from....
Well, it was the spring of 2009 when I bought that MMM, used with only 6 hours on it, so it has been about 15 years. Not bad in the big picture, I guess -- I've only replaced the blades once, everything else still original, even the belt.
BTW, for those interested -- N4557A is now, finally, back in the air! (Apologies for crappy pic)
