Re: oil light came on?
boomers_influence would know if the T260 ever came in a John Deere LGT, and he would be able to tell you what it was equipped with from the full engine model # and serial number. But take a set of photos of the area around the oil filter, with special attention to the oil filter mounting plate/bracket. That would show if there is a port/tap for a oil pressure switch. Then we can find out if it is easy to add just a switch or you need a plate, gasket, switch. Is the wire still there for the 420 oil dash light?
