Was curious if I could get some input on this mower I'm looking at. Guy said its a 1991 (I don't think he knows what he's talking about) and has an 11HP "RED" engine, so he didn't know the exact engine type. 1120 hours 42" deck with GHS, said the engine smokes slightly on start up. He buys and sells equipment but hasn't dealt with Walkers too much, and even asked me what a good price is for the mower haha. He's asking $1500. Any thoughts on price and what year this mower actually is?
