With limited labor (yes, that blue, "limited labor" link is worth the click) this time of year, we are often forced to use our riding "triplex" mowers on the greens daily. Additionally, our mowing commences while it's still dark out. In preparing for the Member-Member event, we double-mowed and rolled for several days, many times having multiple pieces of equipment on a green at the same time.
If you've ever watched the team prepare the putting surfaces, and it looks like a well-choreographed performance, their precision and execution doesn't occur by accident.
Like learning to dance with a partner, there is a good deal of non-verbal communication which takes place from the time the mowers and roller arrive at one green, and eventually exit, heading towards the next. Whether you call it the triplex trot, tango, or two-step, operating in concert with another mower takes time and practice.
