Blade bolt question - direction - on ZT

[Pablo]

Gravely ZT XL 52 Stupid question, new blades on the way - are the three blade bolts RH or LH? Just wanna easy life!!!

If the blades turn clockwise viewed from above, as is conventional, a right handed bolt tends to tighten itself if the blade tries to slip. So that is what they use. I've never seen a left handed one.

On my workplace Exmark they are regular thread direction. The only reverse thread I can think of is on our Stihl weed trimmers.

You will know when you take the old off.

Makes sense. I've on my toes since my last RPN calculator. Thanks.
