Just dragged this out of my yard at home. It’s 3.5 ton on the hook. I tried the HDC as I reversed it down a steep gravelly slope. It works pretty well, the front wheels were locking up a bit so I was losing a bit of steering but if I had locked the centre diff I don’t think that would have happened. It controlled the speed way better than the ranger does with the same load on the same hill. It also pulled it back up that hill way better than the ranger ever could. I often need several goes in the ranger. The grenadier did it no problem although it wouldn’t have done it with the centre diff open.
