Why do you need to keep swapping your topper on and off ? Do all your topping in one go ?
I have no experience of quick hitch systems (but years of experience with tractors), but suspect as muted above, all will have draw backs of some kind, mods needed to implements...changes to lengths of pto shafts, extra weight, extra leverage because things are set further back. Always one implement its not compatible with so you have to take it off from time to time.
To be honest even the most difficult of implements should take no more than 5 mins absolute tops to fit on a tractor that size with a traditional 3 point linkage, a topper is dead simple to fit....what are the difficulties you are having exactly which mean it has took you 50 mins ?
You mention in your posts you are new to tractors. You might find with more practice you will speed up. Are you following the correct procedure when attaching implements ? I will try give you some pointers if you can give some more specifics on the issues you are having, as I'm sure will,others.
