Hello. I recently picked up a used 54" mmm for my bx24. Works great. It looks like the previous owner didn't grease it to often. I know with all the other grease points on the tractor I grease it until I see grease coming out. I tried greasing the pulleys where the belt are and I put a lot of grease in there but I do not see it anywhere. How much should I be putting in the pulleys on this deck? I do to have a manual for the deck. Thanks
