Excellent point.
Thinking it through, it would only happen involuntarily if they fly over 10,000' at present, and that's unlikely.
Or if ADS-B is mandated for CTAF R and they operate there - and such mandate will occur with or without the subsidy in time anyway, although at present it is the deferred stage 2 JCP2.
Let's also look at the weight.
Transponder swap for existing - nil nett.
TSO145 GPS engine, coax, aerial - say 3 kg?
3 kg equals what percentage of the average Ag payload?
Now, I have noted some hefty farm lads flying Ag aircraft. I guess if payload is critical the operators either need to convince their pilots to get off the Australian obesity wagon, or hire jockeys as pilots.
Either way, I think the ADS-B equipment effect on MAUW is comparable to a gnats gnob
Thoughts?
