Kawasaki or Kohler

Hello ILENGINE,
The argument I have heard by many of the environmental purist is the drain plug was eliminated to keep the DIY types from simply draining the oil out on the ground.
The true reason for elimination of the drain plug has to do with type of equipment and more specifically self propelled mowers. Due to the design of the equipment decks you could no longer access the drain plug when the engines still had them. And that goes back to Toro self propel mowers from the 80's. Or even in some cases without were the only holes in the deck were the engine mounting holes and a hole for the crankshaft. No access hole for the drain plug that was there but unuseable.

Most of the equipment that vertical small push mower size engines are mounted on would require a side drain. And that was eliminated years before the bottom drain was. And later versions that still used the bottom drain had an extension pipe that ran from the bottom drain plug out the side of the housing with either another engine style drain plug or just a pipe cap.
 
There can not be any such thing as a residential engine - it would have to be big enough for a person to live in.

If you accept the use of residential you are buying in to meaningless marketing gobeledy gook! :devilish:
The term residential is not used exclusively to mean a building that you live in. Residential is anything that is considered to be normally used at a residence. So an engine designed to be used at a residence is considered residential. Just like a street that is designed to access a residence is described as a residential street.

Residential is the term for lower hour use versus commercial for everyday higher use when it comes to outdoor power equipment.

To change the oil in a push or self-propelled mower, simply tip mower on side (carburetor up), and drain. Most people are lucky if they change oil in these mowers every 3 years, in my experience.

People not changing the oil in their push mowers is not anything new. People have been not changing their engine oil since forever, and the bad thing about it is they most likely also don't maintain their vehicles either.
 
Residential mowers cost less and are rated in hundreds of hours before you replace them. Most residential users use their mower 1-3 hours a week, and the mower will last them 10 years.
Commercial mowers cost more because they use heavier-duty components and last thousands of hours. Most commercial operators use their mowers 20-40 hours a weeks and the mowers can last 10 years and longer.
 
Yes I tip the mowers over to change oil. Drain plug or not I will put new oil in any engine. It's just common sense. I was told by the dealer that you only add oil when low but never change it. I can't understand this?

It is an applicational description, not a literal one.

For the most part it is a marketing level concept to offer different levels of quality to target different income levels and needs of the consumers.

"Residential";

I know what the marketing department mean however a more accurate description would be "home", "domestic", "small area" or "light duty".

The constant drive, by marketing departments, to differentiate their product from other similar offerings, is what causes this miss use of language , that in the end just confuses the customer/technician :devilish:
