Yes I checked out the link u provided. The Mojack looks awesome! There is a big price diff tho - $199 to $450- between the sizes. I hope the EZ will be wide enough coz it sounds like it will hold the weight no problem from what u said about you Cub.
After buying an Exmark Lazer Z HP 46" and struggling with how to safely lift the machine for maintenance, I finally sprung for the Mojack Pro. The reason I went with the much more expensive Pro unit was because of it's ability to handle more weight. In the future, I will replace the 46" with a much larger mower that will weigh more. The Pro unit utilizes a wide nylon strap as the lifter and a ratcheting winch that has the built in safety anti-fall. I've been using this lift for ten years now and I can't imagine living without it. Not only is blade and belt maintenance is much easier, it's very handy and safe for bringing the mower higher for valve adjustments(I have arthritis in my lower verterbrae) used in addition with a floor jack, ramps, jack stands, and blocks of wood. Safety is critical here. Having a 900 lb. machine fall on you will kill or seriously injure you. Whatever an owner chooses to use to lift their machine, please make sure that it is safe and I would also recommend utilizing a secondary method to prevent the machine falling and crushing you. Always on level and firm ground.
