Wayne,
It's not difficult at all.
The mowers aren't the problem.
It's the hours of operation and local ordinances that present the substantive problem..
Today, golf operations start at 6:00, 6:30 or 7:00.
Therefore, greens must be mowed prior to those times.
Many towns have noise ordinances which prohibit a meaningful window for the crew to mow those greens, hence SPEED becomes a critical factor.
Thus, crews don't have the luxury of taking their time, weaving in and around the unique footpad of the putting surface, near features such as bunkers, mounds and dropoffs.
I know of a golf course that doesn't open its doors until 8:30, hence tee off usually starts at around 9:00.
This allows the crew ample time to mow the greens and groom the golf course.
Clubs have changed culturally.
Years ago, young members came to the club at 8:00 to 9:00, had breakfast, played 18, had lunch, hit balls and played another 18, and had a drink or two.
Today, young members tee off as early as possible, at 6:00, 6:30 and 7:00 so that they can get home with their families by mid morning.
That pressure to begin operations earlier, also impacted maintainance schedules, which came into conflict with local ordinances, especially on the weekends.
So, instead of being meticulous, instead of taking the time necessary to maintain and groom the golf course, SPEED in the morning became the PRIMARY factor, and as such, unique configurations suffered.
That's my story and I'm sticking to it.
