John Deere 420: Part 3 - Deck Gear Box Reseal (1)

[@ronaldayers9449]

I’m going to ask the expert… what is the difference between that gearbox and the original ones that came on a JD 261 grooming mower? I’ve got a 2000 rpm rear pto gearbox for the 300 & 400 series and want a 261.. but all the 261’s I can find have been used with a 540 rpm pto tractor. And the have black 1/3 ratio gearboxes on them. Will these gearboxes on these 261’s work properly with the 2000 rpm rear pto that I have? Or will it spin way too fast? I fear of breaking stuff. Thank you sir.

Thank you for these videos! I just picked up a 420 today. My first JD and first compact tractor. I'm hoping to find manuals, get familiar with everything, and do any needed repairs over the winter.

Hi I gotta question concerning a 420. Everything works fairly well on it, except when I engage the mower deck. It will leak oil from somewhere in the front area. What seal do you think it would possibly be that would need to be replaced? Also, that was a nice video you did showing your grandpa mowing grass.

Would that be the back side of Mt Rushmore?

You are within 100 miles :)

Devils Tower?

Nope, Badlands National Park (West end of the park specifically) :D you hit all around it!

One of the advantages of a leaking seal is often the pulley is not rusted on the shaft.

This is very true!

What’s the part number for the gear puller
