I have a 3520 gear with R4s. The tires spin way before it runs out of power. It pulls a 2-14 plow in heavy blue clay with no problems, unless it runs out of traction. I got the 3520 because it has just over 30hp at the PTO, which might someday make a difference on the running a PTO implement that requires 30HP. I would have been wiser to get R1 tires with the 3520, or drop down to the 3320 with R4 tires. The 3520 might be a little more fuel efficient because it is a smaller block than the 3320. I like to see what it will do with chains on the tires.
