Drive Shafts: Two Types of Grease?

It depends on the mower and type.

2 of our mower have spindles that can be greased. 3 of them have wheel bearing that are greasable.

The JD Lawn tractor is hydraulic power steering and has greasable steering joints. It also has a driveshaft that is greasable. It doesn’t use a belt to turn the HydroTrans. It’s shaft driven. And the foot control pivot points are also greasable.

 

I agree, used to buy mobil 1 red exclusively, but got sick of cleaning up the drips out of the grease gun from separation. Seems to drip a lot more than any other grease ive tried. That said, i cant contribute any failure due to the mobil 1. As others have said, use what you have, but USE IT
I now use gray valvoline syn with moly in just about everything. no separation yet ive seen over a couple years.

 

yeah my 3 blade Husq mower has a zerk on each spindle, important to keep those topped.

 

If you ever pull the spindle apart. Don’t be surprised if the bearings are sealed/shielded. To be honest, My experience is that the life span on greasable and non-greasable are the same. I’ve even try balancing the blades really really good. It didn’t make a difference.

 

Grease is Grease!

 

Do you mean are you doing something wrong....because it won't spin with the tires on the ground? No, that's a good thing. If it does, something's broke.

ETA - I did see the "in neutral" part too....but still. Just because the transmission would (in theory) let the shaft spin, don't mean the tires will. There is no "neutral" in the differential.

 

K ty thought I was going nuts

 

Is there any reason not to use Moly lube on all the U-joints?

 

Walmart Supertech Moly. Cheap and it works fine.

 

Just replaced my Output Shaft Seal since I noticed it had a small leak of ATF and took advantage that the Slip Yoke had to come out.

I saw several people use Ford Motorcraft PTFE Grease but my 2006 Toyota Manual states to use “Lithium base chassis grease, NLGI No.2 or Molybdenum-disulfide lithium base chassis grease, NLGI No.2” for the Slide Yoke

based on this I used Mobil’s Synthetic Moly NLGI #2

Has anyone else used a NGLI #2 grease for the Slip Yoke?

 

Scouterjan, did you ever find out if your 2wd had zerk fittings to be greased? I have a 2010 2wd access cab and I'm wondering the same thing.

 

It’s 15 years old. No one knows if it has had the ujoints replaced, and if they’ve been replaced with greasable or sealed u joints. Get under there and look

 

As others have said, all mowers are different.

My Kubota has 4 zerk points, the front wheels and the spindle the wheel assembly rotates on. My Grasshopper, the deck wheels, the rear wheels [front deck design] the three deck spindles, the driveshaft for the deck slip joint, the U joint for that driveshaft and the 2 bearings that the deck driveshaft rotates in plus the deck wheel spindles.

I prefer greasing simply because if done right, the life of the bearing can be measured in decades. Sealed bearings, not so much in that environment.

 

Thanks 545, that's the plan once it's light out. Was hoping to jump the gun on an Amazon order to get the grease and gun delivered today if need be. But you're right, no better way to find out!
