I must be missing something. I have 3 different grease guns, two manual and one battery and never had a problem with the tips on them. I snap them on and don’t have to hold them in place.
It turns out that there was a problem with two zerks on my loader, as discussed here https://www.tractorbynet.com/forums...079-difficult-mx5400-la1065-loader-zerks.html.
My loader has a pair of 90 degree zerks where they should be 45 degrees, making it nearly impossible with normal straight grease guns to get a tight clamp on it. It turns out other loaders of the exact same model have the 45 degree zerks. I'm picking up a pair from the dealer.
Neither the lock-n-lube nor my original grease fitting can get a good lock. After much fiddling and discussion I have a solution now. It also turns out that the original Kubota branded grease gun fitting _is_ adjustable, it was just screwed on so tight that this wasn't evident, and the dealer didn't know when I asked. I've since remedied that with a vice and pliers.
That said, the lock-n-lube is a _lot_ easier to use and a timesaving thing. But I've gained a lot of hindsight since my original post, and that pair of incorrectly angled zerks caused a lot of problems diagnosing things.
