It is a self-leveling grease.

The urban John Deere lawnmower dealer may not have it on hand but should be able to have some transferred from an agricultural location within a couple days.

"Steering gear lubricant" is the correct lubricant, but what is that? The main goal is to use a lubricant that is self leveling, not too thick and not too thin, but just right  . I mixed my own grease by using a combination of 120 weight gear lubricant and bearing grease. Mixed it together until I got the consistency I wanted. For me, that was easier than find Corn Head grease and I can replicate it at any time if top-off is ever needed. | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | Although John Deere Corn Head Grease may be a good choice,(I have not used it or taken a box apart that has) especially for a leaking box, there is nothing wrong with using 90w on a box with good seals.
I have rebuilt a lot of steering boxes and what ever you use make sure it flows. Using grease is not much better than having nothing at all in it.

Steering gear lube is a self leveling grease, as is cornhead grease. I'm sure any number of combinations will work so whatever give a peace of mind is the stuff to put in.

Kurt | | | | | Joined: Jan 2011 Posts: 152 'Bolter | | 'Bolter Joined: Jan 2011 Posts: 152 | According to info on corn head grease tube there are sealing properties which may help a leaky seal. | | | | | Joined: Mar 2005 Posts: 1,513 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,513 | I installed a new seal when I rebuilt my box and found that 90 wt would weep onto the spring/frame but switching to cornhead grease stopped it completly. If it's got gear oil in it removing the lowermost cover bolt will allow most of it to drain out but cleaning out grease may require disassembly.
