Good day.
Welcome.
IMO it’s only a fail if nothing learned.
if not sure why it was difficult I would suggest:
1. Reread the manual. Be very aware of how much it will hurt if your toes are under an implement and the fall in some way (ie partial connection and loving the implement into place…if it comes off the pins it will crush what it lands on, be it you or someone else. - be aware of the stored energy and your hands / feet / etc). This applies to the SSQA when release an implement on the front too IMO.
2. Take manual in hand and stand back, and look at just the three point links and look at how they adjust (turnbuckles and their range of extension/contraction, as well as spreading the width), reconsider if need to change how or where drop the implement (ie. Store on dollys on concrete, or maybe find flatter area, or plan to shim them better align)
3. Do you have pallet forks? Move the pallet to more suitable location. If no pallet forks, I’d remedy that ASAP they are very versatile…or don’t, JMHO.
4. If still gapping, do you have a jack and some blocks of wood?
IMO there will steep learning curve each time you attach and disconnect.
Dust yourself off, it’s happened before.
