I have an embankment 60 metres long. The slope is approx 45deg. The
height varies from zero to 4.5metres, but is mostly 4 metres. The slope
is grassed, the grass having been planted the year before last. I now
have the problem of mowing. I've done it once with a strimmer and a
ladder, but never again! I've heard that it can be done with a hover on
a rope. Has anyone any good idea about this, other than mountain goats?

Yup, perfect for a groundcover or three. Don't know what the
soils and rainfall patterns are like where you are, but using a variety
of species tends to protect slopes that might otherwise slide off in a
heap during heavy rainy seasons. The varying root structures appear
to be key to avoiding

Is this a cut slope or a fill slope or natural? Has anyone looked at the
angle of repose for this soil?
