ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades PTO generator source

I've been trying to find a source for a portable PTO (Power Take-Off) generator which can be coupled up to a tractor as and when needed: Single phase 240V, around 5kVA or so.

This is a little out of my usual field, and so far most of my searches have only turned up PTO generators of much larger sizes, typically 20kVA upward.

Any ideas for a source?
