This Old Toro mower is a perfect example of it take more than a reel grinder and height of cut gauge to get reels dialed in. I ground these reels, set reel to bed knife contact to .002 clearance. Paralleled the rollers to the bed knife and height of cut to .875 of an inch. The customer was bringing it down from another dull rental mower, so it took a few mows to get the grass down and scalp marks out to see the full effect. I came back to do a follow up and to repair a few other items on the mower and seen it wasn’t mowing correctly. I rechecked my setup and reset the contact, mowed a couple of passes. The mow was better, but still streaky. I back-lapped the machine with 80 grit which made it better but still not right. Using a prism gauge I was able to see the difference in each reel. By adjusting to down pressure springs and attitude of the bed knife I was able to get the reels cutting very consistent. There is still some play in the rollers but for a 20 plus year old mower it’s mowing pretty good. Sometimes you have to spend sometime making passes with the mower and making one adjustment at a time to resolve cut issues.
