'Herman' pulling 9 - 16s. Often referred to as an El Toro, this tractor is factory powered by a 4-53 Detroit Diesel. The tires are Goodyear Terra Tires, also a factory installed option. This was my first time trying out this plow, and didn't think it would go nearly this well. I think with some tweaking and a gauge wheel on the back plow, I can make it go even better.
