Pawnee and Ludwig,

It appears you both have bad seals on the output shaft of your gearboxes. I just purchased the seal and washer-retaining cup for my Woods MD172 cutter. The items were only available from a Woods dealer, but were in stock and only cost $8.00 with tax. I have an older Ford 901 cutter and have replaced them in the past for about the same price. Go to Bush hog’s website and either email them or call their 800 number. They can fax or e-mail you a breakdown diagram with part #s. Sometimes you can match up the seal at your local NAPA or bearing supply store. If you don’t have a part number is better to contact the manufacture. The grease issue is hit in this forum on a regular basis and the opinions are like belly buttons there are innies and outies. I have put grease in older slow speed gearboxes on other types of equipment when it was not possible to obtain a seal, but would not do it for the long-term on a bush hog. The problem is the grease may not make it into the bearing down below the bevel gear and it will not help even out the temperature of the components the same way the oil will. If you put new seals in it would be a good idea to turn the shaft by hand every now and then during the off season to keep the seal from sticking. My Woods is designed where it is virtually impossible for wire to get to the seal (the usual cause of failure), but the unit sat in the shed for about a year and the seal stuck. Last comment, it does not take long to pay for a $4 to $8 seal when you are constantly adding 90wt oil and a tube of grease the gearbox every time you use it.
