Another possibly dumb question. I have the Liftmaster on my Gravely, which utilizes the mower's hydraulic system to raise the front of the mower for service, but it is somewhat cumbersome for shop use. For that reason, I'd like to buy a Jungle Jack, or similar device for blade changes, etc. I've never actually been up close and personal to one, but have seen pictures on here of them being used. From those pictures, it appears the jack is actually placed under the leading edge of the deck itself. My question is, does this cause a problem with floating decks such as that on my Gravely? Also, any of you that own one, what brand would you recomend? Thanks.
