Thanks all ! I down loaded that publication BarBender. Thank you. It looks pretty comprehensive.

 I'm always impressed by the Scandinavian small scale harvesting methods, Gman. Things like a radio remote control winch (or a cable controlled one like they feature in the publication) are fairly simple things that would really boost productivity. 

 A lot of old loaders used a hydraulic cylinder tied to a chain, that went around a sprocket that is affixed to the mast. Anything that is powering the crane swing has to be able to withstand pretty good shock loads.

A lot of good ideas here to think about. I like the chain or cable drive thru a motor (old Warn winch?) or cylinder. At my age production isn't important but making things easier so I can still enjoy working in the woods and having something interesting to try is.

Thats an interesting publication, i think there is a lot of info that many people could use

Latest Project
Converting my JD855 FEL to quick attach.
Critical requirements were to 1) limit the amount of added weight and 2) not increase the distance from the pivot points. My loader capacity is limited enough as it is. I found a few adapters available on the web, but every one failed badly at 2)

Started with a pair of quick attach plates from the web.
Created a pair of ears from 1/4" plate with some 3/4" S80 pipe.


After a number of careful measurements, welded the ears to the quick attack plates. Bolts for spacers. 





Added a stretcher bar.


 And paint.

Next I built mounts for the bucket



That's where I am now. I just need to cut the old ears off my bucket and weld the new brackets on. In the meantime, I'm enjoying the use of forks.

You'll want to add some ears at 45° to the back of the bucket to guide the QA in when you go to book up. I did on mine and went from multiple tries in 5 minutes to usually first try in a few seconds.

All done except for paint

Got a dozer blade in need of some welding repairs, all you fabricators out there, what is the best methodology to go about it? 

I've got lots of steel for replacement but not sure the proper way to do it. 

I'm honestly surprised at how thin the metal is. 1/16" of an inch at best

[doc henderson]

looks like a lot of material is worn away.  may need to build it up or add material.  My brother could fix it in a heartbeat.  I would have to think about it.

[NE Woodburner]

What make/model dozer? How much do you use it?

You probably already know this, but it's thin because it is worn. It was originally a lot thicker. You mention having lots of steel for the repair, but you should do some google searches for the proper steel to use. Also, if the blade is that worn you should check the bottom of the push arms as that is a common place for wear and not as easily noticed.

Not sure of your fabrication skills, but this may be a job for a professional. I work for a construction company with dozens of dozers, excavators, loaders, etc. and we have several buckets and dozer blades rebuilt each year by one of a few local professionals.

@NE Woodburner its a John Deere 750k lgp I think it's a 2019... I'm going back to work in the bush for the next several months, site prep, scarification and road work. 

Since it isn't my machine, the decision isn't mine to make unfortunately, I am a capable welder, and could probably patch something in to get through the season. But I'll have to take the information to the boss and let him decide which route he wants to go. Thanks for your advice! Greatly appreciated!

Blade probably needs a new liner welded in it. Pretty big job. Make a cardboard template of the curve in the blade and take it to a steel supplier and they should be able to bend it to fit plus they should know what kind of metal to use for that application. If not wanting to go that route just have to weld patches on worst places.

If not wanting to go that route just have to weld patches on worst places.

That is why I was asking about use. If this is an everyday, heavy use machine being counted on to make money I would have it done by someone with experience and use the correct materials. If it is a short term or farm type use you could probably buy some time by patching, even with the incorrect steel. Just be realistic with expectations of how long it will last.

if the blade looks like this after only 5 years it has been a machine as discribed!

Hardox is used for blades and buckets, one of the hardest steels out there. sit down when they give you the price
