Second hand Golf buggy with 36V electric motor works a treat for our Arrow:
I did quite a bit of research and most of the US - made single wheel tugs are not guaranteed by their manufactureres to work on (wet) grass: they are mainly designed for tarmac/concrete surfaces:
Don't be tempted to fork out 4-figure sums of bucks only to find out the hard way they don't work.
If you've got elecy in your hangar (for charging) go for electric motors: if not you'll have to have a petrol powered bike thingy: but remember you get what you pay for: it'll be NBG if you can't start it.
Safe flying
Cusco
