Very hard to find the parts list for these, almost impossible to get parts.
When MTD bought Gardenway, they bought the Troybilt tiller line, bought both the Bolens and Troybilt names to use as they wish,
Let Murray have the chippers and whatever, and chitcanned the rest. So any Bolens stuff will be real old stock...
I have had my hands on Bolens microfiche a couple of times, sold almost instantly on e-bay, I sold way too cheap.
