Thanks for everyone's advice I believe you've solved my problem. The torque spec is 38-50 lbs, I will try with a ratchet socket to test failing that I will organise the 15 gardeners with a torque wrench
Thanks again 👍
I work for a gardening company and I maintain the Bushranger mowers, I have been using Victa centre bolts to hold the blade plate on and the teams I have replace their own blade by removing the centre plate to access the blades, we have been using battery tech screw guns to loosen and tighten...
