I'm trying to find a magnetic tach for my pto I'm using adapters going from my 1000rpm pto on my 4840 to 540 rpm adapters but all I can find on the net are tach for race cars. Please if anybody can help with some info I would appreciate it a lot.

LOST IN TEXAS!!!!!

I can't say that I've seen anything like what you're describing, but if you want to make sure you're not exceeding 540 PTO rpm when using the adapter, just use the tach in the dash. Your 4840 will produce 1000 PTO rpm at 2200 engine rpm.
Since 540 is 54% of 1000, you need to run your engine at 54% of 2200, or 1188 rpm. I know the tachs in the 10/20/30/40 series tractors aren't that accurate, but as long as you don't go over 1200 rpm, you should be fine. Maybe that will at least get you buy until you can find what you're looking for. My two cents.

p.s. - I have seen photo-tachs that read with a strobe light and reflective strips, but they have all been diagnostic tools, and not really for permanent installation.
