718ZDoug 0 #1 Posted July 31, 2018 Newbie here! Just found a 718,Z mower/ dinosaur? Haven't got it home yet but would appreciate any and all info and knowledge about this machine, has been stored prob. 10-15 yrs. They think it had a exhaust problem!!!! Hope that's all that's wrong!!! But, for the price I can sink more money into it. Again any and all input is greatly appreciated. Thank you Doug Share this post Link to post Share on other sites

Let us know what it ends up being. https://www.partstree.com/parts/search/models/?searchTerm=718-z Clicking on a line will bring up the parts lists.

Pullstart 67,093 #6 Posted January 11, 2019 @718ZDoug there is a 728-Z being parted out in the greater Grand Rapids area. I’m sure you’d be the only one throwing elbows to get to it, most likely! With some crafty searching, I’m sure you’ll find it if you need anything... Share this post Link to post Share on other sites
wh500special 2,277 #7 Posted January 12, 2019 (edited) The 700’s are good mowers. Very simple, kind of crude machines. They are pretty tough, but do have a common weakness. I had a 724z, a progeny of that 718. And I parted and salvaged parts from a few others to keep it running. That was a number of years ago so I don’t remember many details, but enough to suggest that once you get it operational and mowing that you will want to be gentle on the transmissions. Best not to abruptly slam from forward to reverse and vice versa. And keep everything clean to allow them to Cool and change the fluid regularly. The flywheel side of the engine feeds power into a dual-output right angle gearbox. The two outputs each separately feed into an integrated Eaton 7 hydrostatic transmission. One on each side of the tractor. One turns Clockwise, the other turns anti clockwise. They were commercial machines and meant to be driven hard, but it’s not at all unusual to have one of the transmissions pop. They are easily replaced, but I don’t think they are rebuildable and are pretty hard to find. I think the CW rotating one is the hard one to get. All of them I parted had blown the trans on the left side. I guess since that’s the non-discharge side of the deck used for trimming that the left wheel gets drug and reversed more than the right. When my user blew the left trans a second time and I was out of spares I parted it out on eBay and made some money. Anyway, they are a neat machine. Don’t be afraid to bring it home and tinker with it and use it. But be aware that you’ll want to take care of it to increase its chances of even longer survival. At 30+ years old they could need some nursing. Steve Edited January 12, 2019 by wh500special Share this post Link to post Share on other sites
