We later bought this one https://meadowcreature.com/collections/broadforks that has tines similar to those in your link. It worked much better in our then rocky soil....but we moved to some land that was a black clay that was impossible except at a vary narrow moisture level window and then had to stand on it and wiggle it a long long time with every bite. The tines are not removable but I can't see them breaking or bending although I suppose someone with more strength than I could do it
Our son borrowed the second one and worked a lot of not so rocky new garden area with it.

I have the meadow creature fork. The times are not removable. It works great. It would be very, very hard to damage it. I would buy the fixed tine one you can get locally.
The one in the link you posted has wooden handles. I'm not sure how that would go with heavy duty stuff - it would work fine for going over existing beds, but for using on compacted heavy soil or around lots of rocks it may not go as well as a full metal one.
