Another day of learning about mmm decks.
1. Guess how many grease zerks there are on an MF mmm deck.
If you guessed 6 or 8 . . you'd be wrong. The answer is 12 if you include the following:
Rear deck wheels 1 each times 2
Front deck wheels 2 each x 2
Spindle 1 each x 3
Tension pulley 1 each x 1
Gear box shaft 1
Shaft to mid pto 1
Plus there are 2 spots to apply grease that don't have zirks (gear box race and shaft to pto snap ring)
2. I always use a high temp RED grease so it shows up. Last year I greased my deck 3 times . . Always till grease showed . . Or 3 pumps where I couldn't see (covers on etc.) Well today I had all the covers off and cleaned everything up. Then I greased everything. I was a little surprised how the spindle zirks I pumped 5 times each and still didn't show grease coming out . . So 3 more pumps each and dark grease came out (not my red color). So obviously 3 times last year x 3 pumps each on each spindle had not driven old grease out and now 8 pumps each is finally pushing out the old grease. My point is . . The spindles sure seem to take considerable grease.
Woah, I was surprised today too when I greased my MMM. The spindles took a ton. I need to order another couple tubes from amsoil.....
