You will have a lot of fabrication work ahead of you as the Defender bumper is nowhere near strong enough for anything bar nudging sheep or cattle round the field, far easier and probably more aesthetically pleasing to save a few more pennies and buy a decent winch bumper, I know that it all comes down to cash but for safeties sake, deffo worth it as winching puts a lot of very high stresses and forces into play.
