Thought I'd post this one from last summer . Some of our verticutters seemed pretty tight and hard to spin while others the plates seemed loose . I get a chuckle out of this find . In the past I've worked on Jac a Toro verticutters . They both had solid shafts and after changing blades you tighten the nut till you got the play out of the plates .
Looks like its solid . I did snug up the loose ones .
Then one one set I noticed that the more I tried to snug up the loose plates the harder it was to spin ???
After closer inspection I found that the ends are separate pieces roll pined on .
Takes very little torque on the nut to cut the pins off .
Not a big deal but did learn something new to me .
And thought I'd pass it on .
