Reel mowers. My first real job was on a golf course. We used walk behind selfpropelled reel mowers for cutting greens. They were Toros, specialized for the job. The diameter of the reel was perhaps 4 inches and 2 feel long. They cut by having the reel rotate against a flat metal piece called a bed knife. The course had 3 greens mowers so each one would mow 6 greens every morning starting right before sunrise. These mowers were fast enough to jog behind going from green to green and we did jog because you had to get the job done before the golfers got out. The job would take 2 1/2 to 3 hours to do. I figure we put around 11 or 12 miles of walking every morning before we started doing our other work on the course.
Each week the reels and the bed knife were pulled off and put on a lathe then worked with some kind of sloppy grinding compound. After grinding they were tested using paper. They cut that paper like the best kind of scissors..sharp as sharp can be. Then adjusted for cutting height.
The pay was good though. I made 60 cents an hour.
In the mid 60s golf courses were a chemical dump. I suspect that this many years later if soil testing was done on older courses they would be declared chemical wastelands. We used so many hazardous chemicals for fungicides, pesticides etc. Mercury was sprayed on greens as a fungicide to name one kind.
Which leads me to this then I'll stop. One of my neighbors has his lawn treated by a lawn service company. I'm sure the company says its all natural, good for the environment type of treatment. He does have the best looking lawn if you think best looking is greener, thicker and no weeds. If thats the standard then he wins the gold metal. But theres one thing I have noticed while vaping on the front porch of my home. No bird, and I mean no bird has land in his yard all season long. Well OK, I have seen two birds land on his lawn and immediately left. However the yards surrounding his property always has plenty of robins, grackles, sparrows etc happily hopping around doing their thing. I wonder what those birds know that my .... retentive neighbor doesn't know or if he does know just doesn't care enough to do anything about it.
Now I gotta go make some coffee and wake up.
