well this is more about my really great son ,who i would do anything for and am so proud of. had to say that boys ,daddys will know what i mean. loaned him my lazer to cut his grass ,its a new place and they just let it go in the drought. all three spindles w doubles are meshed togather in a way that will take some serious air to ever get them off. i hit a tire carcus once and a dog chain . the only time i ever did that to a set of doubles. how he did it to all three spindles ,i cant guess. just hope he didnt mess a spindle up. moral ,do not loan your primary mower to ANYBODY. even my son as great as he is.
