Not sure how to adjust it properly, any and all help much appreciated.

If it's new it shouldn't need adjustment, bolt it up and go cut grass.

doesn't work like that. The 3 nuts need to be adjusted "air gap" but I'm unclear how to do this.

rather than my explaining, key in electric pto adjust in the search box and there is lots of info available. Clearance is 10-18 thou."

I think there should be three openings (ports) along the side where you insert a feeler gauge of the correct size. turn the three bolts/nuts until there is a uniform correct gap. Not sure what your gap should be.

I got it adjusted guys, thanks so much for your help!

Well done. Keep an eye on the amp gauge. Mine acts up if the battery gets a bit low. Not the fault of the pto but took me a while to figure that out.

Don't think there is an amp gauge on a JD 420 L&G tractor.
Factory/stock: battery\charging system warning light on the instrument panel.

FWIW:
A section in the TM 1590 describes in detail, with photos, the removal, disassembly, inspection, assembly & installation of front pto clutches on 316, 318 & 420 L&G tractors. Couldn't hurt to ask your dealer if they'd provide you with those pages. Only 5 or 6.

CD versions of the TM 1590 are cheaper than hard copies & often handier as you can look up what you want & print just the page(s) you want to. JD-D
