My 60D auto-connect MMM has always been a bear to connect, but this time I've spent almost two days working on it without success. I started with the above sticky on the mower setup. I did everything posted there, made all the recommended adjustments, put the left rear wheel back on, and still no-go.
I drive over the mower on a flat concrete surface with rubber horse mats, and when I reach a certain point the mower slides with the tractor. I've tried blocking the mower on the barn fence. The following two pictures are what happens every time.
This picture shows how close it comes to the locking point.
And this picture shows the mower gearbox shaft and the 1025R mid-PTO connection. It looks like the connector won't move any further forward, and then just keeps pushing the mower away.
