Does the 10301 have the aluminum-cased clutch/gear pack with grease fitting at each rear wheel? Or, do you have to remove the wheel to get to the drive gear which has a ratchet built into it? If it has the grease fitting, lbpod is right - two pumps max. You need to use NLGI #2 or lighter, down to #0. If you read the cartridge you have in your grease gun, it probably is a 'lithium complex' grease anyway. I like to use white lithium grease on them, but I don't have any mowers of that type anymore. On mine I have to take the wheel off, which is not wasted because I clean and grease the wheel gear and axle at that time, to get to the ratchet gear. I use mineral sprits and a toothbrush to clean the gear, then shoot it full of spray white lithium grease using the center hole in the axle. You can also use a grease gun there if you have the rubber-tipped 'point' accessory. I just did the rear end on one of my mowers the other day, and I used some grease I've had around for awhile, 'Slick 50' #2 grease. This stuff is green in color but has a nice consistency for manual greasing of axles, gears, etc. I think basically any #2 or lighter grease you find at an auto supply will work. Manufacturers state the type they use because it is known that mixing grease types is not good in high-pressure applications like vehicle wheel bearings and ball joints. For a mower axle or clutch housing, it's probably not very important. Mainly you don't want to over-service that housing because it will make the wheels drag on pull-back.

Tomplum - "looked like it fell off" means when I removed the right side wheel, there was no washer or clip on that side. Since I never looked inside before, I had no basis for comparison. I now have replaced those with new ones from Toro. No dice. I followed Saxman's advice and cleaned up the ratchet on both sides and still no dice. I'm now thinking that the pawl my be gone too. I can see the spring clearly but it does not appear to be pushing anything. Also, what may be a dumb question about the gear...it should read R on the right side, correct? I.e., the R should be facing out and not in toward the mower. Thanks for your help. Guess I'll go back to the Toro site and study the diagram some more. Thanks again - MV

I lean towards worn gears. They can look super, but still be worn to the point of not meshing. As you stated, they mesh enough without any weight on them to turn the one wheel, but can't turn it under a load.

I will tell you what I go with, for my internal drives I go with Western Digital Black Caviar drives they are more expensive usually but extremely good drives. The last one I got was a 500Gig Black Caviar which I believe I got through amazon. For my external drives I like seagate free agent pro, I like their warranty and features. western digital black caviar
