The book says 8 zerks to grease. I greased the front spindles and wheels (4 zerks). Can't find the one on the steering ??? Where is it ??? I greased the mower deck mandrels (3 zerks). I pumped my full size hand held pistol grip grease gun 50 times and i don't see any grease squeezing out of the mandrel anywhere. One pump is about a 1 inch line of grease. When i grease the front spindle I pump till a little grease squeezes out the top or bottom. How much should I pump into the mandrels ???
