I've been considering this grease gun and grease for quite a while now. Seems every time I reload my old grease gun I remind myself that there has to be a better way. Then I would look into this system and balk at the price. Well, I recently wore out the ball joints on my JD x728 tractor, and they are welded to the ends of the tie rod. That makes them very expensive. The dealer parts guy suggested it was probably because I wasn't keeping them greased as much as I should. This in spite of me more than quadrupling the service cycle that is recommended in the manual. Be that as it may - I now intend to grease them even more frequently, and decided to "treat" myself to one of these Lube Shuttles, and add a LocknLube end to it (which required an adapter due to German standards vs US standards on the threaded ends). It was still expensive, but compared to my JD tie rod with welded on ball joints, I think I'll be better off in the long run. Thanks for bringing this back to front of mind. Nice to have an easy, quick, and reliable grease gun when laying upside down under the tractor on the cold winter concrete floor of my garage. Anyone interested in a very used OEM John Deere MIA 880702? With access to the right fab shop, I'm told one could easily cut the ball joints off, weld new ones on and have an entirely serviceable system for peanuts.
