I looked at the Bobcat model and JD models of both 72". Bought the JD for $1650. Bobcat wanted $1900. Your price is good. The only real difference between the two, are the grapple tines. Bobcat had 4 individual pointed tines on the grapple and the JD more of a claw with better reinforcement of the 4 tines. I thought they would get bent less on the Jd. Bobcat does have a wider opening for the grapple which is a plus for the Bobcat. Jd does have one more bottom tine than the Bobcat but I don't think that makes any difference. It really came down to price for me.
I use mine to pick up brush and trees after we shear them with Dymax tree shear on my Bobcat 873 and put them in piles or load them on dump trailer. For a CUT, the grapple seems plenty heavy for my use. I didn't want a heavy brush grapple on the front of my JD 3720 bouncing across the pasture. I won't be using it to dig out trees or roots. For heavy duty use, I have a construction bucket and grapple for the Bobcat 873.
The bottom tines are pretty heavy. I can jump up and down on them and can't imagine bending one. If I just lifted up the FEL with one tine, it would probably bend. Due to the relatively close spacing of the teeth/tines, sometimes brush gets stuck on the tines and I have to manually remove them.
The bobcat brochure shows them picking up round bales. I have not tried that yet but should work great for hay/staw in bales or loose.
It should be about the right size/weight for your toolcat. Your toolcat has a little more lift than my JD 3720. If bobcat comes out with a 3pt toolcat, I will probably get one.
