Ramlok from Lincoln security specialist Lincmaster is designed to fit any machine with hydraulic steering rams.
It takes less than a minute to fit, says the company, and costs £145.
Fitted over a fully extended ram (on full steering lock) it is held in place by a retaining pin which is secured with an armoured, anti-pick, anti-pull, heavy-duty block-lock with up to a million combinations. Lincmaster also makes very substantial locks for trailer hitches, ATVs and any other kit you don't want to go walkabout. Details from 01522 544 848.
