I stopped by my local Exmark dealer and he said he had a good deal for me. He shows me a 2005 Exmark Viking 48" / 15 HP KAW. The mower had never cut grass but showed a little wear from the sun and bumps and scraps from moving it around. So I decide to demo the unit. I pull it off the trailer and fire it up. I make aprox. 4 passes and she lets put a small puff of white smoke. I pay no real attention to it until the next pass. She lets out a massive white mushroom cloud that would rival a nuclear blast. I shut it down and scratch my head. I look at the dip stick and the engine oil is white. Nice, its full of gas! So I take it back and they find a busted diaphragm on the fuel pump. Nothing against Exmark, but it left a bad taste in my mouth. I did buy a Toro Proline today. 44", 17 HP KAW, floating deck, bagger, electric start and 225 hours. I picked it up for $1800. I was not really looking for a new mower since it would sit over the winter and not pay for itself, but I felt like it was a good deal.
