MMM Front Link Disengaging

[George56]

Front link disengaging from the hooks on the MMM. It's happened 4-5 times already this year. If I back over a tree root or such it will push the deck forward and off the hooks - that's on me. This seems to happen randomly and I don't realize till I raise the deck. Going to remove and re-install the deck today. Any ideas? Thanks

Thanks! The book calls for a measurement of 47mm (1.85"), will check and may adjust .25" to see what happens.
