This video shows a Grillo G107 walk-behind tractor, powered by 8hp diesel engine, operating a PTO-driven trailer. Of course, in this configuration, it is no longer a “walk-behind” machine, because the operator is sitting down and driving it! While the terrain in this video is not very challenging, rest assured that this beast will handle some very rough terrain. Load capacity 2000 lbs, trailer has manual dump to rear. Most of the video shows travel in 3rd gear, but right at the end I put it in 4th gear…which, with the larger-than standard wheels this unit is equipped with, tops out at a bit over 10mph.
