JDcrawlers Messageboard

Hi, I buy my oil from Deere. So, Turf-Gard 10w30. Before that it was their Torq-Gard which was also 10w30 IIRC. Mine is a 58 and was sold by my Uncle out of the family JD dealership new to a dairy farmer. Dad grabbed it when it was traded in 1966 for, I think, a Mannheim 820 with a loader. I wound ...
