An analysis of walking greens mowers also reveals a similar pattern. A
22” Mower in 1991 was $2,500 and is over $4,000 today. The machine is
heavier, causing more compaction, and is more physically demanding to operate
and transport from green to green. Clearly, today’s superintendent is not
getting much help in lowering expenses from the equipment manufacturers.
There are also some other issues relating to chemical usage. In our part
of the country, snow mold protection has actually decreased in price, but the
new formulations without mercury appear to be less effective. Warm Season
courses are going to have a very interesting time addressing their insect issues
in light of the banning of a major insecticide base.
We have also
encountered some significant issues relating to USGA Specification Greens. While
the laudable attempt to equalize drainage, simplify watering programs and create
a uniform growing medium has been widely accepted; the costs associated with
USGA Greens maintenance are higher. That also does not address the “black
layer” problem that has appeared in many new greens. The USGA
Specifications have proven to eliminate some issues, but the vagaries of design,
sunlight exposure and air movement usually still present superintendents with 18
unique growing mediums.
Dr. Hurdzan also addressed the potential for
GPS to help minimize maintenance expenses. GPS may have a lot of potential, but
the days of turning over greens mowing and ticklish chemical application to a
remote control are still quite a ways off. When that day comes, get ready to
have an on-staff MIS professional at a salary comparable to your current
superintendent/agronomist. At present GPS based maintenance is an expensive
luxury with very little real potential for cost saving.
