Protect disk blades

[Jim Meade / Iowa City]

What do you use to protect a bare metal surface such as a disk blade or plowshare from one season to the next?  Specifically, I'm thinking of the disk openers and coulters on a planter.

For several years I painted disk blades, coulter, and field cultivator shovels with plow coat black paint.  A big job, messy and have since decided that anything stored inside isn't going to get this treatment, which now is everything.  Although inside I still have coated the plow bottoms but they haven't been used for the last ten years.  However I don't wax equipment and rarely wash anything.  Instead they get the leaf blower and air compressor treatment.

The absolute best product that I have found is from Rhomar Industries.  I use it on all my Iron that goes in the ground.  Yes, It is still applied by painting or pump-up sprayer but it is well worth the time for keeping off rust.  Only a few hundred feet thru the dirt and whatever you put it on is shiney again.  You can Google it, or if interested, I will see if I can find out some information on the 5 gal. jug.

I used to spray diesel fuel and maybe a little hydraulic oil on discs and blades that were going to be stored inside. If they don't get rained on..that is plenty to keep it from rusting over the winter. Then I got to wondering what that was doing to the rubber wheels on the planter...and quit. It also made a mess on the ground that I'm not sure I want to deal with later. I kind of wonder if something bio-degradeable would work...like Soybean Oil......

If it's going to sit in the shed, I just put a board under the planter openers so they don't sink in the dirt.  I don't paint the disks at all.

  WD-40 on the planter discs.  The rest of the machinery I don't worry about.
