Shivas,
One of the big selling points to triplex or riding green mowers was the labor savings.
Remember, you're asking minimum wage workers to repeat a process on a daily basis, with the same diligence you expect in the performance of the lawyers in your firm.
Labor costs and costs affiliated with labor can mount up.
One only has to look at Lehigh to see the costs associated with maintaining all of the flower beds and decorative areas around tees, greens, etc., etc..
Maintainance costs are a real concern, and they aren't heading lower.
Just look at green budgets today, in comparison to 10-20 and 30 years ago. It's the same golf course, but costs have skyrocketed.
