Disc Harrow Alterations

[deere5105]

Here is a quick shot of my progress. Next step is to start on the blades and axles. Only issue so far is I am a little bothered by how easily the paint seems to chip. Used Loctite Rust Treatment, JD primer and two coats JD paint.

Looks good so far:thumbsup:

How cold was the metal when you painted it?

I would say the average temp would have been around 70 when both primer and paint applied. Paint seemed to go on better the warmer it was. One good thing is that the JD green spray seems to match perfect for touch ups.

While making plans for the next phase of my project, the blades, axles and bearings, I looked at how the Frontier disc units were painted. It looks like the hangers, spacers and all hardware below the frame is black. I am considering going with the Frontier paint scheme. I remembered reading somewhere about paint designed for pieces that contact the dirt. Question is, is anyone familiar with the JD Soft Black Coating paint? It sounds like it is best suited to just the parts that contact the dirt such as the blades themselves. I really do not plan to paint the blades after each use. Thought using the black below the frame may make things easier to touch up in the future since the blades would be black anyway. Seems it would hide any overspray better than the green. Any thought or suggestions?

The soft flat black paint you speak of was intended for the dash panel on older Deeres' such as the New Generation Twenty series. If you wan't a soft black paint with good rust preventive characteristics I would suggest a coal tar epoxy finish. Used on lots of marine applications, barges and drilling rigs. It is a two part paint which I think holds up really well, I have probably sprayed several hundred gallons of the stuff years ago.


Not familiar with your disc but It may well have been painted yellow below the frame. Might look on Machinefinder to find something similar to yours if it matters to you.

The paint description on the JD website stated it like it was almost a temporary paint. Stated it would come off when the blades began to work in the dirt. Not sure that sounds like something I want to try.

The paint scheme is not being matched to the original. It was originally red from what I can tell. I figured the black would better match the scheme that the Frontier units use since I was going back with the JD green.

Tonight I got into the bearings. Of the eight bearings only two didn't want to turn by hand and somehow a third was missing all together. The race was still there, but the bearing itself was missing?? Attached are a few pictures of the bearings removed. Have heard bearings called many different styles. What would you call this style? Anticipate any trouble finding the same style, type bearing. They appear to be very well sealed and it wouldn't suprise me if some of these weren't the original bearings.

That is a square bore bearing shouldn't be any trouble to find I hope.

Matched bearings up yesterday at local tractor dealer. Price actually better locally. Blade and axle prices much better on AgriSupply, if shipping isn't too bad. Got to look into that now. The bearing was a W208PPB12, w208ppb12 .

Blade question. On AgriSupply site there are two blades I am looking at. Both are 20", 5mm thick blades. The India blades are a 1070 Carbon for about $20 and the Brazil blades are a 1080 Carbon for about $25. Question is it worth the extra for 22 blades?

For the time,$ and effort your putting into this project,IMHO yes I would pay the $110 plus tax for better quality.
