I’ve been selling a remote-control mower for some years now. Under the Ransomes Jacobsen label it’s called the Spider and is used for steep embankments where trip hazards are common. It will do the work of three men with brushcutters with the added advantage that the operator can sit in the Transit and keep mowing if conditions permit (a brilliant selling point!).
We are now on the Mk3 version, and each mark is a different size to cater for different customers’ needs. I’ll try to find a picture to add to the post.

That’s the one, Angus. Great fun when you first start to drive it, but after a couple of hours into an 8hr day you can get very bored. Still…. what else could you drive on a steep motorway embankment in the pouring rain whilst sitting in a nice warm Transit cab with a mug of tea to hand? Much better than standing up to your knees in wet grass getting covered in all sorts of unmentionable things that you find in long grass.

When the Maidstone by-pass(now part of the M20) first opened they had a dragline excavator with the bucket replaced by what looked like a fairly standard Hayter Orchard Mower. They would sling it up the embankment and let it back down under gravity. Don’t think that it was a great success!

interesting gizmo Geoff.lots of development I am sure. don’t want to pull it to bits,but with the addition of a quick mountable ring for each wheel with say 3 inch spikes protruding it would not get wheel spin on tyres going up hill in moist or high volumes of cut brash areas. very nice all the same.

…….and pick up litter at the same time! However with that crab-steer function it can easily work its way across the bank rather than the more spectacular straight up and down.
