That's the set up I purchased last December. With the BH on, traction is not a problem. I also have the back tires loaded. I think the BH weight is 700 to 800 pounds? Don't remember for sure.

I have this setup with R4's. The BH adds a lot of weight/traction to the back. It does take away from clearance though. I really feel the difference between using the BH, Boxblade, or nothing.
I have the TC24D without the BH, but the turfs are loaded with washer fluid and with the back blade on, I run out of power before I run out traction in FWD on a gravel road or dry lawn. You shouldn't have any problem with traction with the BH hanging off the back.
