Re: Hay storage

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Love it Harold,

As an involuntary volunteer (my wife trains and raises horses), I have had
to stack my share of hay bales.  Alfalfa and Timothy Hay are the two I am
familiar with, the Alfalfa comes in short bales (90 lbs) and long bales (125
lbs) while the Timothy tends to be right around a 100 lb.  There is definite
variance depending on whether it is first cut, second cut and the moisture
content.  I agree I would lean to the conservative side, as we tend to stack
it to the rafters as tight as we can get it.

You forgot to mention Alfalfa has the stiffest stems and will scratch up
your arms more than the others :-)
