I've cleared about an acre with my L4060 and stump bucket. I stay in M-low, I could see getting into trouble in L-low. No issues so far.I was really eager to buy the stump digger for my Mx-5400, to basically remove large brush—-until yesterday, when a previous user told me how they dig in with the slightest forward movement and severely bend the front end loader. This would cause major expensive repair. I’d like to hear from other users.
