Here is the homemade toolbar I have made for my Howard 200.
I have used the front and rear parts from a scrap rotary hoe gearbox and bolted them together. Then using some gash angle iron and a length of 25mm sq section bought on-line I bolted it all together. The attachment was picked up the COEPS spring sale in April, I think it might be David Brown in origin.
Have yet to try it out, which should be fun !
The other pictures show that like many members, my machines are practical and bought to be used.
