Sorry, I don't use putty or plink (and actually since they aren't part of 
the Cygwin distribution, much discussion of them is off-topic for this 
list).  But I expect your problem isn't putty/plink specific but rather
operator-error.  I can reproduce the same "problem" you're reporting with
'ssh' (which is part of the Cygwin distribution).  I believe you want:

plink -batch -2 -i C:\path\to\my\key\mykey.PPK -l tims 159.87.127.66 'echo $PATH'

Does that clarify what's going on for you?
