Homebrew Jobby, made from a Stanhay push seeder grafted to a Merry Tiller. It’s the Blue and Red item in the middle of this picture taken at the West Country Game Fair 2014. it is owned by Roy Watts (left) of Somerset, also in the picture is Sue and John Philips..
Its not a merry tiller, is there another make that uses a similar chain case idea, the drive axle is hexagon going right through the chain case, also it has a PTO on the opposite side to the drive pulley that turns at half seed. I will post some pictures soon.
If it’s an aluminium chain case it could be Honda, they used a hexagon shaft and the F400 Tiller had a PTO. Be able to see better when you put those photos on.
After a bit of research I think it is a Landmaster, very similar to a L160 but not the same, the wheels and bottom half of the chaincase are the same. see this link to the old website
