I bought the MechMaxx SG24 and after a month or more, finally used it. Shipping was not an issue, came faster than quoted. Crate is metal and well protected. Checked all torque of bolts and used. Works like a dream. Did about a dozen stumps, ranging from 6" to 36", no issues. Well, one issue, and it was operator error. Left my drawbar on and when I was grinding below ground level, it cut open the plastic sheathing and got into the driveshaft. the driveshaft fared better than the 1 1/2" drawbar. I would recommend this based on my short term use so far. Not sure how many years it will take for me to verify it's a great product, but I'm sure I will get more than my moneys worth. I only wish the chainsaw holder was tall enough to use a bar protector. Maybe I'm overthinking the need for the protector, but I always use it.
