Well, I have to chime in again since I just spent a lot of time on my mower this weekend. I will admit that changing the oil absolutely sucked. I tried to use a piece of notched pvc pipe (only thing I had) to divert the oil to the hole and since it wasn't pitched in that direction, a lot of the oil got under the engine and all over my belts. Someone mentioned a tube in a previous post. Mine didn't come with a tube, just a plastic drain plug with an o-ring on it. Was it supposed to come with a tube? Does anyone know if a drain valve cab be put on these engines? I've seen them for cars so that all you have to do is turn a valve to get the oil flowing. A tube could then be attached to the valve and it could be routed to a drain pan out of the hole. Anybody know where to get one or what thread they take? I also removed the deck to install a mulch kit and put a new set of blades on. That was hard due to the weight of the deck, but I found no engineering flaws there. Very straightforward and not bad for my first time. The mulch kit didn't get installed because I was missing the hardware kit. Not sure if I lost it or it was never shipped. I failed to check it when I received it. Mowingman saying the Gravely rides better than the 1500Z is crazy but I would expect that from a gravely dealer. I rode the comparable Gravely (I think the 148Z) and it wasn't even close. The ferris rides much better. As far as non-greased moving parts, check the manual. Aside from the shocks (which don't require lubing), there aren't many moving parts that are not greaseable. I also looked at the black pads also mentioned previously and don't see the concern there. If they do wear, which mine show absolutely no sign of doing, they are screwed in and easily replaceable. We have been having a lot of rain for the past two weeks so I had to mow wet bahia that was easily 12" tall. It took a couple of passes to mulch it up really fine since I didn't have the mulch kit installed, but it really performed well. As a new 1500Z owner (and a new ztr owner), that is my personal unbiased experience on this mower.
