John Deere BWA disk

[Pumpkin Steve]

I have a 14' BWA that needs new 18" disk blades. I checked with vendors this winter at a farm show with little luck, one guy said to avoid shoup because they wear out rapidly. What is a good source for blades and bearings? Or is it too expensive for an old disk? And, how do you get the axles disassembled??? I tried to get one gang apart but she be tight. Thanks

Agri supply has any size blade you want. How much you want to spend is up to you. As for the axles — BIG wrench with a looooong cheater handle on nut and BIG pipe wrench on an axle spool to hold. You may need to heat nut cherry red.

When it comes to old disk axles (aka arbor bolts), heat and a big impact wrench are your friends.

Thanks, I can get the nut off........but I can't slide the blades or spools off.

Use your BFH. Big @@@@@@@@@ hammer. Probably rusted in place.

Back when I sold new JD BWA disks I was thinking 20'' disks is what was on them. If disk harrow has been operated with a loose disk shaft nut then dirt can pack between shaft & square spacer interior causing disassembling problems of disk shaft assembly. Tapping outside of spacers helps loosen the compacted soil.

They can get packed full of dirt and get hard to gat apart. Be careful with a hammer as those spools are cast and break easy. I usually bang on the blades and haven't broken any spools that way.

Does Deere still sell the Earth Metal blades? They were the only ones I ever found that held up.

That was CIH

Have bought disc blades from Shoup and they wear as good as any.

Deere had something similar, close to the same name. I bought some back when there was a Deere dealer here.

If trying to loosen the hard packed dirt and rust i have found that water and time is your friend. If you have a pond or large water tank grease up the the bearings and submerge gang in water for a day. Otherwise if you can stand gang up and run a trickle from water hose on top so water can soak down shaft and spools slide off easily. Steve.

Always thought 20 inch blade was as small as I wanted. Figured they would pull easier by keeping the spools just above the ground in loose dirt.

 

[matthies]

I would take the nut and outside blade and spool off and disk some ground with it to loosen everything up.

 

[Roger in Iowa]

Chain wrapped several turns around spool and then frame will hold gang from turning.

I agree with what 2SteveWI said. Put in water over night and it fell apart.

It can be a job. Big hammer, put the nut on loose and pound on it to shock the axle through the blades. Be careful to not wreck the nut or threads, but need to shock down the whole shaft. Along with sharply tapping the blades, spools, etc. heat and so on as others mention.

Shoup has as good as any blades. At times they had stuff that came from Brazil, and stuff from Mexico or other countries. The Brazil stuff was better. I’m not sure if that is still a thing, that was some years ago.

CIH had better blades ‘earth metal’ that wore a lot longer but cost a lot more. Sounds like JD had similar. So yes, these would be better than what you get at the generic farm supply places.

Are you sure you want18 inch, I would sure 100%put 20 inch on if they fit? They wear down fast enough, get as big as you can if you are going through the expense and work of this.

I guess the only reason I said 18" is because that's the size that is on it. After reading your response and others, I'll go with 20's. I bought this disk a few years back, and it seems to be a bit discombobulated. I suspect parts were robbed off of other machines to fix this one.

And the very few acres that I use this on, blade wear isn't really going to be an issue.

Thanks for all the replies. I'm looking forward to getting it rebuilt. Sorry for the double posting thing above not sure how that happened.
