Recently I got a N-503 lift arm tool and N-502-B gauge. The N-503 was advertised as something else and when I got it I found it was not what I needed.

These are for setting lift adjustments on a NAA series tractor only.

Before I list on eBay, I thought I would offer them up here, as this forum has been really good to me with info for my 861.

PM me if interested. I would also be interested in a swap/trade for a NCA-502 tool for the hundred series.
