    For years I’ve been having my mower shop change and sharpen the blades on my mowers. I want to start having my workers change them. I tried using my ryobi impact driver to loosen the nuts but not too much luck. (Only 2000 impacts per minute). This impact wrench here says it produces up to 3200 impacts per minute. Should I expect this to be sufficient enough in removing the nuts?

    Just get out a breaker bar and get those spindle bolts loosened. Then use the ryobi from here on out and you shouldn't have any problems.

    Do you think 300 lbs of torque enough to tighten them though? The ones the guys use in the shop I believe are closer to around 1500 lbs of torque. I wanna be sure that they’re not going to constantly become loosened while cutting.

    I was originally looking at this one actually. I might go with this if I decide not to get the ryobi. I already have a bunch of ryobi tools though so I figured it would make more sense to stay with the same brand so the batteries and chargers were compatible.

    The ryobi may be rated fro 300 ft/lbs of tourge but most likely in this application is only going to deliver around 75 ft/lbs of torque give or take. I've seen spindle bolts require anywhere between 65 to 120 ft/lbs of torque so the ryobi should be just fine. I personally tighten spindle bolts by hand to maybe 65 ft/lbs and if I have to change a blade in the field I don't have any problems.

    How tight are you guys going? Sheesh, my 18v dewalt still puts them on and takes them off with very little issues. Occasionally if I hit something and they tighten up I’ll have to bust out the air impact but that’s like maybe twice a year.
