I have TruTrak air clutchs on a White 6100 planter pulled by an Oliver 1855 tractor. I've run the air clutches for two years and had no problems at all.
In my case, the electric clutches would not fit on the planter because it had right hand drive where as most planters are now driving form the left side or have an adaptor to handle newer right hand drives. TruTrak was the only thing that would fit. I put them on myself and had zero trouble.
I'd imagine the electric is newer and maybe better - I don't iknow - but the air works for me.
