Cut my yard for the 2nd time today with my 42 inch sport. Excellent cut in quick fashion. Decided to go ahead and change the oil (recommended for an initial change at 4 hours). Now I have my first beef with the unit. Mine has the 17.5 Hp B/S engine. Not sure that it makes any difference since the owners manual for the unit is universal although I have a separate engine manual.
Anyway the means provided to drain the oil is as described in the owners manual, slightly different than the B/S manual. What is provided is a flimsy 'quick open so called valve' and an eight inch piece of tubing. The tubing is necessary because the drain valve is located probably 4 inches from the edge of the steel engine deck. Unfortunately it takes virtually the whole eight inches to extend the drain off the edge since you have to bend the tube to get it behind the tire. After removing the dust cap, and fitting the tube to the nipple, you are to turn the plastic valve to the left and pull it straight out to initiate oil flow through the valve and nipple. Mine was so flimsy that it slid off the metal fitting, spurting oil everywhere. After shoving it back on and having to refit the tube while oil is coming out, since the tube being so bent to extend to a drain position was not happy about having the connection on the other end turned/moved and decided to come off. Eventually the unit drained, with a cup or so laying on the deck and in the 3/16 inch wide gap between the engine and the frame behind the seat. After mopping up the bulk of the oil and being amazed that anyone could engineer an oil drain system 1000X worse than the one I had on my Dixon that I often had unpleasant thoughts about, I proceeded to examine the 'valve'. I found it cracked. Not that I placed any unusual force on it. I seriously doubt that anyone actually could be expected to successfully use the drain system provided on a routine basis, (I'll allow that you might get lucky once). Perhaps I'm overlooking something major other than what was provided. Anyway, have any sport owners come up with a better valve/drain system? I thought I'd ask before heading back to the dealer.
The Honda engine has a quality brass value located directly over the drain opening in the frame. I expect the Kawasaki is set up the same way.
