Quick and dirty video on how 2 take a part this gearbox and repair.
I got all my part numbers at first from the old bearings and seals then found out almost all brush mowers / slashers / rotatory cutters have the same bearings and seals. Even if the outsides look very different. This was a on a very old pull type 5ft gear box, but same as most 3pt brush mowers. Measure your bearings and seals to make sure they fit the internet will give you the dimensions. But my part #s should give you a good start
3x 6208 bearing
1x 6207 bearing

Thanks for sharing. Be aware that adding or removing gaskets of varying thickness will affect the mesh between the gears resulting in a change in the root gap and backlash, which may take it out of spec.

Greetings, I accidentally came across you video and I want to thank you for taking your time to post it. I have a question for you. My uncle is a farmer and he has almost identical New Idea No. 452 brush hog. His problem: two gears inside the gearbox are all torn up, pretty much destroyed. Everything else seems to be in great condition. Do you happen to know or have an idea where we could procure the replacement gears? I spent 3 days searching the internet and practically zero leads. It seems that New Idea Farm Equipment has shutdown in 1999, and many of its products are now collector's items. Thanks for any info you may have.

Oh man..there are random Farm sites that still had parts. It might be easier to find a used gear box on eBay or something
