WOW....what a long, drawn out debate over lifting a ZTR for service!!! I don't have any way to use an "engine lift" mechanism, so I opted for getting the MoJack since my automotive hydraulic floor jack wasn't a viable option. I will say, however, that no matter what you use......be SURE to put decent jack stands to support it after getting the machine lifted. I say that because I had a 3 1/2 ton Craftsman hydraulic jack for about 10 years and used it to jack up my vehicles for oil changes. I never gave any thought to it....I just jacked it up and changed the oil & filter. A few months ago I was changing the oil in my wife's car, jacked it up and went in the house for something. When I came back out the car was sitting on the ground. I said to myself...."self, didn't you jack that car up"???? So I jacked it up again and noticed that every two times or so it lifted the vehicle it went back down a little....and after finally getting the car fully lifted I stood there and watched it drop back to the floor in about two minutes. Right then I realized why I had the jack stands that I never used and that "ALL" hydraulic(or otherwise) lifting devices CAN and WILL eventually fail. I went to Harbor Freight and got a good deal on a replacement floor jack(Sears no longer sold the one I had and I read some pretty bad user reviews of the current jacks)......but I must give the best advice given so far in this long thread(actually one user mentioned it earlier). When you lift "anything", especially a ZTR that weighs several hundred pounds or more....PLEASE secure it with some decent jack stands before getting underneath the machine. I can just picture me lifting that car with the old Craftsman hydraulic jack....crawling underneath it....and two minutes later needing to be rushed to the Emergency Room. Don't let that happen to any of you!!!!!!
