After posting this up l found a pdf and figured out what we had bought.lt is a Series 14,12 hp hi-vac Snapper mower.
Got a good education yesterday from a older mower repair shop.Bought a plug,and a air filter.Fresh oil and spoke to the mechanic about what we needed to do.
Bought this for my son who has a decent sized yard at his new place.We did a lot of maintenance to it,including sharpening the blade.Runs good but waiting for the rain to stop now..
l’ll reach out to rosie BK,thanks
