The sulphur content will wipe out bronze bushings (Yellow metals) So where is the cornhead grease on this scale? Unless you've replaced the sector shaft bushings with needle bearings, I'd be very nervous about using cornhead grease in the steering box. For more info, check "Yesterday's Tractors" sub section Ford 8N.

The NLGI rating for John Deere Cornhead grease is “0”, or soft grease. Regular grease is rated “2”, or normal grease.

Because it is soft grease it is well suited to be used in places with moving parts because it settles back down after movement stops. Also it is thicker than 600w oil which helps it from leaking or dripping out. Cornhead grease will not effect bronze bushings.

My experience has been that this product works very well in Model A steering boxes and u-joints. No leaks, no problems after many years.

I would be very interested in anyone’s confirmed comments on steering box failures caused by Cornhead grease.
