When I bought my 7520, I chose a used one with a "pin style" quick attach over the new one with the skid loader type quick attach. I got forks and a bucket with the used one.
I decided to buy a grapple bucket but adapting to the Mahindra quick attach soon got complicated so I traded up to the new tractor.
With the new one, I got forks made of flatsteel like the normal forklift style. The Mahindra forks were made of ~2" boxed steel, useable but limited.
The skid loader type quick attach is "the nuts".
I happened to stop by the dealer yesterday and while there, he showed me a quick attach hydraulic auger attachment made by the same outfit that manufactured my grapple bucket. I hate it when he does that to me.
