Like I said...about 98% of the full grapple jobs being done that get pictured here can be done with a thumb...
logs, root balls, rocks/boulders...
Not everyone that has use for a grapple/thumb has a quick attach system...changing from a pin on bucket to a grapple can be a PITA....thumb type grapples can generally be taken off a set of forks or a loader bucket with just a couple of lynch pins etc...
Not sure what your point is, so what, there are multiple choices in the market and that's the beauty of it.
For example you can go to work in a scooter, rollerblades, a car or a Battle Tank...You choose.
By the way, the majority of your comments haven't been any helpful and are quite annoying.
Not sure what is your contribution to the particular subject.
Whish you a happy Friday.
Hope you understand that there are multiple opinions and there is no need to insult, call names or make derogative comments to those that have a different mindset that yours.
