I've never had an issue with mine dropping anything. One thing you need to consider is how you will use it. There is a range from the shortest position to longest that you specify when you buy one. One of the things I use mine for a large mower and a seed drill both of which are 3-pt implements. I put a short length of chain between the implement and the top link. This allows me to shorten the top-link to pick up the implement rear higher off the ground for transport. When using the implement, I lengthen it until there is slack in the chain. This allows the implement to "float" on the ground. A 3-pt drill typically leaves gaps when going over uneven ground where a tow behind "floats" and follows the contour of the ground better. With my setup, the 3-pt drill works like a tow-behind for operation and a 3-point for transport.
If you are going to use it like this, you need to figure out the right length for both the shortest position of the toplink, the longest position, and the length of chain you will use.
Thanks,
