So,

I pull the plugs on these two New Holland hay rakes (258 & 260) boxes to check the oil.

Appears that someone, at sometime had put in white lithum grease instead of 80w90.

Took my grease gun and gave each box a very healthy dose of gun grease. Is this gonna come back to haunt me?

Mix a little 90 weight oil with the grease and you'll be fine, seals may have been leaking is why it was done.

'Corn head grease' is now the approved stuff to use.

I've put gun grease in as well, but it won't melt quite as soon so not quite as good....

Dunno.... You're worried about the different bases causing the grease to harden? I would guess that it probably will harden... but a bit of oil might prevent that?

My Deere 662 bar rake appears to have had grease in the gearbox from the factory. Not even a drain plug in the gear box. The gearbox is nice and tight which is about the only thing on the rake that isn't just about worn out.

I wouldn't worry about it.

I rebuilt the drive line(from wheel to wheel) on a 256 back about 1994. Went to the local NH dealer and asked what oil went in the box. They pulled up a bulletin and showed me that NH had switched to regular tube grease. I added a grease fitting and just about filled it up. Added a couple of shots each spring. Sold that rake to a neighbor and it's still going today.

Wheel bearings on your car are greased, so why not.

Oh, I see.

That's what I needed to know. I'll quit frettin' over it. :>)

Thanks Guys, I really apprecitate the help.

Hey, this subject has got me thinking...
I have a Galfre drum mower that has a shaft drive, with two small gearboxes with 90 degree miter gears to get the power to the drums.

The oil seal at the bottom of the first gearbox is very leaky, like I have to re-fill it every time I cut (capacity isn't that much, maybe 1-2 quarts). Changing that bad boy is going to be a real bear, and I'm already into the hay season. Maybe I could put grease in it? With a little gear oil as suggested? What do you think???

That's actually what my dealer recommends.

Stupid question time:

What is "gun grease"?

Anonymous-0 · Jun 6, 2012

I've read on here that JD corn head grease works. Probably other brands are the same.

Had a lubrication specialist at a meeting. Mixing greases can be a VERY bad thing as some types of grease react and form acids that can corrode away the metals in the gearbox or bearings/ bushings being lubricated. Mixing Litium based and another type caused the reaction. Wish I could remember exactly now but the bottom line was to NOT MIX GREASE TYPES!

Bob Bancroft · Jun 6, 2012

Indeed. I worked at a dealer '72-'84. Even then NH had given up on oil and said to pump two tubes of grease in there.
Now the corn head grease I think is even a better idea.

I have a CCM 2 drum mower with the same bevel gear drive, I have run cotton picker spindle grease which is the same as corn head grease for many years, no problems.

"Gun grease" simply refers to tubes of grease that are dispensed with a grease "gun". NOthing special.

Dad bought an old NH 55 rake bake in the '80s. Seals were out, so he pumped it full of grease. Last year I had to replace the bearings. It worked for us for 25+ years....

Been using Cornhead grease for awhile now, havent had any problems.

Steve in VA · Jun 6, 2012

I believe you are referring to mixing lithium based and sulfer based. Sulfer was common years ago and when mixed with lithium gets really interesting. At the very least you can end up with a brick rather than a lubricant.

I have used grease in a bush hog. It worked until even the grease wouldn't stay in. That bush hog was beyond worn out to say the least.

For years Land Rover, International, and Toyota used an enclosed swivel in the forward end of their FWD. All used 90w. As the seals wore or the swivel ball pitted the 90w leaked out and everything failed soon after. A whole lot of us just pumped the swivel/burfields full of grease and forged on. Not the best solution but never sacrifice 'good enough' simply because its not 'the best'.
