    I don't think it'll work...Oil in the soil is not the best way to till...Fix it or buy another gearbox...

    Well who'd of thought...

    AMSOIL Semi-Fluid 00 Synthetic EP Grease is recommended in the following agricultural applications:

    Rotary mower gear boxes

    AMSOIL - Semi-Fluid 00 Synthetic EP Grease (GSF)


    I'm sure most all lube mfgs. have the same thing.

It is called Millenium 2200. I actually had thought about getting some and replacing all my gear oil with it.
    I talked to Patty at Texas Refinery Corp and she recommended using the 880 Crown and Chassis Grease (NGLI #00). They only sell to end users so the product must be ordered directly from them. A 5 gallon pail cost $100 plus shipping.
    After learning that I oversee offshore drilling rigs she offered to send me a free quart to try out. I will keep the group informed of the results.

    Use a 0 or 00 grease.. like JD cornhead grease ( made for corn head gear boxes )..

    I guess mighty dodge and amp sucker have never seen a flowable grease.

    Just curious here, is this semi fluid grease better than using gear oil? What's the benefit? No leaks? cooler operation? I'm interested. I aint gonna by 5 gallons but I'm interested.

    Some applications spec a nlgi 00 grease. JD makes their own brand of 'cornhead grease' for instance.

    I have a large rotary mower that states you can use 85/140 or 200/300w or 00# grease in it.

    Flowable grease generally doesn't leak out of a weapy/leaky seal like a gear oil would.

    Regular grease will form a cavity around a moving part.. and unless it melts or is vibrated enough to slump and be picked back up.. it can starve the gear of lube running in that hollow cavity. 00 grease will slump and slowly flow and thus fill voids and be picked back up by gears and bearings... etc.

    For a system needing gear oil.. go with oil... Grease in an oil system is a bandaid. ( depending ont he application.. it works not very well, or pretty good.. all things considered ).

    That looks to be an excellent option as well. I didn't know that the 880 C&C Grease was available as NGLI #00. Usually TRC lubricants have to be ordered through distributors. Actually one of the members here, DieselPower, is a distributor. I have been meaning to get some grease from him for a long time now. Actually I was going to buy Moly 880 C&C grease as a general purpose grease including for my loader and get the Millenium 2200 to fill my gearboxes with. The Millenium 2200 has a Timken OK load rating of 65! Now I'm no lubricant expert but that just seems crazy insane for a flowable grease!!

    It seems that it works long term on farm machinery for everybody that does it. Nobody recommends it tho.

    I have a gearbox that still leaks after a new seal and careful inspection. I think the shaft is a little wiggly. Not really reparable. I'd need a new gearbox. So I put a few shots of grease in with the gear oil. That did the trick. Not a single drop since.
