Hi,
I have a Fordson Power Major with no tacho. My idea is to fit an electronic meter because of the problem we have here in Australia finding a second hand one. (Rare as hen's teeth). What my problem is is to find the gear ratio's in order to know what ground speed I am doing. ( I use the tractor for spraying). So if someone out there could help me I would greatly appreciate it.
Thanks in advance and Merry Christmas.
