grease in a rotary cutter gear box?

[Soundguy]

SOME boxes on some equipment DO ship with a grease instead of an oil. My Howse 10' hd mower shipped with a thin spec grease. I have a magrix spreader that shipped with a sealed box and grease. Some mowers and lawn equipment use grease in their drives instead of oil. I buy my 00 grease from a lawn mower repair shop.

I do not understand why they don't come from the factory with cornhead grease. Would save a lot of gearboxes.

Oil flows better & ends up lubricating a touch better I expect. Easier to measure the level & change. Also, the lower the viscosity, the less HP loss.

HP loss based on a pint of thick liquid gear lube that is very very close to pourable 0/00 grease anyway? In a mower gearbox? What are you talking about? 1 micro hp loss? Something that has to be calculated because it's way to small to be measured?

I'd wager that crud buildup on and under the mower deck adding weight to the mower would be more 'hp loss' than a pint of very thick oil vs a pint of very thin grease!!!!


Wow....

What is this statement based on? Have you used thixotropic grease? Have you seen any videos of it when it is flowing in a gear box, just like oil?

Here is a video:

My Center gearbox on the 12ft. bush hog got cornhead grease last week. Saved the day and cut 115 acres of thistles before seed heads set. CRP ground and had to be done. It worked for me.

If Brown Manufacturing specifies cotton picker spindle grease, I figure it's OK. I think Brown knows a thing or two about gearboxes.

...even weeds that wind up and then get forced into the seal face.

Exactly what happened to mine.

OK, here's MY take...

The seal let go on my Rotary cutter many MANY years ago, I've been putting grease in it ever since. What kind of grease? ANYTHING I can get my hands on, I don't believe it makes any difference, as long as you put "something" in that gear box!

Some years ago, a guy gave me a large amount of grease from waaaaaaay back, all different brands/kinds and I'm still putting a half of tube of which ever brand/kind my hand hits when I need some. I put it in before a BIG job and don't worry about it one bit... Even heavy grease will flow some, once the box warms up and every time I look in the box, there is grease covering all the gears/shafts.

My gear box it still quiet and this rotary still cuts perfectly, well as perfectly as the used blades allow! And YES, my rotary cutter get's used HARD all without issues...

You guys argue everything to death, just put what ever grease you have, in and go, I bet you it won't make any difference in yours either!

My dad did the same thing...
He called it "hard grease"...
