I won't be around my tractor for a few weeks, but when I get to it next I plan on checking the torque on the lugs for my 50 hr service. I know they are larger than 20 mm, the largest socket I had when I looked while doing the oil changes. I should have put a tape measure on it at the time, but I thought it would be easy to research. I cannot for the life of me find the nut sizes in the WSM or Manual or online. Anyone have any idea where to find, as I'd like to purchase before I get back to the property? Or anyone suggest a large socket size 1/2" drive kit, like 20 mm to 30 mm for the L47 wrenching work? And I assume they need to be deep sockets based on the attached pic. Thanks in advance.
