I have stepped back from croquet this year but I looked after the
Jamberoo lawns for many years and we laser-leveled one of the
lawns about every 2 years commencing with our 3rd lawn in 2010.
Laser leveling is carried out with a special tractor which has
balloon tyres (to not leave tyre tracks) and a grader blade which
is automatically raised or lowered hydraulically by a photo sensor
which detects a rotating laser beam from a fixed beacon. The
laser beacon is set off the lawn to provide a rotating beam at
whatever angle is required. Although it is called laser leveling,
the beam does not have to be set level. If, for example you
wanted to have, say, a 0.5% fall from south to north then the
laser beacon can be set to provide such a fall.
The sensor on the laser leveling machine detects the laser beam
and raises or lowers the grader blade independently of any hills
or hollows the wheels may run over.
The guy we have used says that he needs about 10 tonnes of good
quality top dressing soil per croquet lawn (eg for about 1000
square metres). The contractor we used recommends that the
maximum soil thickness after leveling should be no greater than 18
mm in any area and the level accuracy is better than 10 mm.
I am not right up-to-date with the latest costs but 10 tonnes of
high quality top dressing soil runs at about $70 per tonne (eg
$700 worth) and the laser guy charges about another $800 so all up
about $1500 on top of a normal renovation. (ie the lawn should be
scarified, aerated and fertilised before leveling)
I am away from home at present but I could send you a video of
the laser leveling being carried out on one of the Jamberoo lawns
if you are interested.

Has anyone had any experience with laser
levelling of croquet or other courts.
Has it worked okay, What about over time?
What equipment was used, tractor, grader or other?
possibilities in the future on our courts at Maitland.
