I had to do a post on this one photo from the tractor show this weekend. I pulled my dad's hay wagon with 13 people on it Friday night and people were staring, taking photos and video. The 616 did slip a little once in a while when we got into powdery dirt, but it pulled this around the grounds for about 30 minutes. Not too bad...
I'll be honest, that certainly helps!! However, I believe it is the loaded AG tires that makes a huge difference. I tried pulling the water wagon over from my brothers house with my nephews B207 and it could not do it. Did not have the weight. Then I took over the 616 over and it did it. With the loaded tires, the rear weight, and me, I reckon there is almost 400 pounds on the rear wheels. And it needed every bit of it. Certainly not what the designers were probably planning on for this, but it sure is fun.
