With the unprecedented warm weather we been having here in south west Ohio, I put the tree puller to the test plucking honeysuckle, roots and all, and a few trees up to 5 inches in diameter. Comparatively speaking between Skid Pro tree puller and competitor tree puller that I also looked at, the Skid Pro model wins hands down. The boxed jaws and covered hydraulic cylinder are just two major benefits. I did not see the need of the optional brush guard that the other model offered. The Skid Pro model is a very stout piece of equipment that I will use in the years to come. Thanks again for a great piece of equipment and fast delivery.
