| Picked up a used Woods 121 bush hog. We have used it on about 12 acres so far and I parked it in the shop over the weekend. One of the gear boxes is leaking a small amount around the output shaft seal. It has gear oil in it. Should I tear it down and replace the seal or drain the gear box and fill it with high temp grease? I thought I have seen new ones that switched to grease instead of gear oil? |

| I can't speak from personal experience but others will chime in about the use of corn head grease as either a temporary or permanent fix if you're trying to put off tearing into it at this time. Good luck. |

| I had an older 15' brush hog that had both outer gear boxes leaking and I drained and filled with high temp grease and I ran them that way several years until I sold it. Never had a problem with it. |

| We use moly grease in ours and no issues. Corn head grease is thinner and may work through the seals soon. I know our gear boxes ran hot with oil and are much cooler now especially doing corn stalks. |

| We run corn head grease in almost everything that has an old gearbox. It still may leak when it's hot from running but wont when its not being used. |

Well, fwiw, the manual on my old Woods 72-2 state that a small amount of gear oil WILL leak and it's perfectly normal, just refill as needed. I'll try to find the manual and post a pic of that page, but it literally states that it's "normal." ...maybe I misread, "abnormal."  ------------- I need more than 200 characters for my "signature." I'd love to see that changed to 250! |
