Just bought a 1994 model year. It has the Kawasaki single cylinder air cooled engine. It also has a 48" deck and cuts very, very nice. The old Wheel Horse was getting pretty tired and decided it was time to upgrade. Cut the grass at my church this afternoon with it and was real pleased with how it performed. Took 3.5 hours and it sure has a lot more power than the old K181 in the Horse. I'm using Shell Rotella T-5 10/30 oil in it. I use this oil in the truck in my signature. The Shell is dual rated and carries the API SM classification for gas burners. Just started using it. I thought it would be nice to use a single oil in all my OPE, and the Dodge.
