What does your front grapple winch set up look like? It's a hydro winch mounted on top?
I had something like this in mind for the rear on the PTO

Yes. It is a 12k hydraulic winch, much like what you might see mounted on a rollback wrecker. It is mounted on top of the backing plate for quick attachment to any skid steer. It's just about perfect for reeling in big wood and loading it into the grapple. I've even loaded 5' diameter logs into it, even though the grapple itself only holds a four footer. Then I can gently lower the log down into the truck with the winch, too.
I load the winch with 100' lengths of 3/8ths Amsteel. Although the steel cable is much more reliable, it's a lot harder to handle than the pliable Amsteel rope. We can roll out enough rope length, and then fling the steel hook a great distance to whatever log is being pulled in. That would never work with a wire rope (cable).
Unfortunately, I couldn't get Bobcat to sell me any of their "smart controllers" that I could hook up to my bobcat's proprietary electric controls for multiple hydraulic functions on one attachment, so we just connect a momentary contact switch and a 12volt hydraulic valve to select between grapple or winch functions. In case of a wiring problem, it defaults to the grapple function. Unfortunately, I didn't manage it to do both functions at once, which is probably just as well. With a little bit of simple wiring, the grapple/winch will attach to any machine with a skid steer attachment plate.
It is currently attached to my tractor, on account of the Bobcat having lost the engine.
I suppose I could have just installed a 12k electric winch, but my first need for it's use was cleaning all the trees out of a large drainage ditch for a billboard for about 900 feet. There were a LOT of trees, and all the cut material had to come 30'-50' up a 1:1 slope. I figured that an electric winch didn't have a 100% duty cycle like I needed, so I went hydraulic at a considerable increase in investment. It's been a great investment, and there isn't anything like it on the market, either. Somebody, somewhere might make one, but I haven't seen it.
