That was me. The horse was called Hector.
There is a plastic extruded product called "strip-seal". It consists of a white core tube and a black channel. The sheets go between the two as the white tube clips into the black channel. It can be made to order by Stephens plastics of Corsham in Wiltshire. That is where I had mine from.
A trip down memory lane. This was Hector with a cart full of silage. Much better through snow than a tractor.
Neighbour was milking on a old db engine, single unit
It can be a milking machine pump or a slurry tanker. I have used both. The picture shows a pumped down clamp where I used a neighbour's slurry tanker. Other kit and a soil covered clamp are visible on this image.
Do you have more pictures or videos of the process?It can be a milking machine pump or a slurry tanker. I have used both. The picture shows a pumped down clamp where I used a neighbour's slurry tanker. Other kit and a soil covered clamp are visible on this image.
And the horse
Yes. The pictures I have been showing you are from a website but I am not allowed to direct you to a website. If one of you can work out the web address from these clues then one of you can tell the forum where to find the details. I call this process "Yalland Vacuum Compressed Silage". My son has created a website with that title, but no gaps, and it needs three W's, and a dot before it and a dot and "uk" after it. Sorry about the riddle. Good luck. The farm on Dartmoor is called Yalland and that is where I worked on developing the Jowsey Doutre method until I retired.

@DavidJLance What did it smell like on opening? Genuine question - the look of it intrigues me.The quality of a well made vacuum compressed clamp can be exceptional which is why I kept using the method until I retired in 2002. The photo shows a newly opened clamp in 1991 that had zero waste, zero effluent and the sheep ate the lot.
