Matt, the l had a few rough edges, the l2s and 3s were great machines. Simple and easy to work on. There are several things that should be checked every season: Jack up the front wheels so they just clear the ground and get a crow-bar under the tire to check for play in the bearing. If you run the bearings loose, the big gear can either wear a hole in the case or explode the final case. The bearings on the main clutch shaft should be replaced every 5 or 6 years. If you ever let them spin on the shaft, it won't be cheap to fix. When the bearings have been replaced, tighten, and I mean tighten the nut that holds them and the shaft together. 600 lbs_ft isn't too much. The drive rubbers for the walker pan and sieve should be replaced every 2 or 3 years. Do not use a lubricant when you press them on. Even though they may look OK, if they're worn, you will shake your pan or sieve apart.
