I recently had a Predator 38 radio remote petrol stump grinder on loan while my Predator 28 radio remote was having the main cutter head bearings replaced. I used the Predator 38 for around 100 hours and it gave me no problems whatsoever, which is a little different to my Predator 28 machine that I purchased in October 2016. How do you find your stump grinder, is it problem free or does it need constant attention? I really like the cutting efficiency of the Predator and the ability to narrow down to 26 inches, which is a great feature. I have written and made a short video review of my experience with the Predator 38 and 28 stump grinders, I would be interested to hear your thoughts. Here is the link to the Predator 38 and 28 review.
