I have recently acquired a couple of greenfields. One is a Tractor 8 with the cast alloy piece at the front and when looking at it from behind it is leaning to the left. The other is a Tractor 11 21st Anni Model. This ones has a good chassis but no cutting deck. Ideally I would like to retrofit the cutting deck off the 8 to the 11 as it�s chassis and steering is a better design. Problem is I can�t find any documents on how the idler pulley setup is on the Tractor 11. I have these parts pictured.
