Tom,
Here is just how easy it is to add a drain hose to any engine. I used the Bobcat CRZ parts manual to get their parts numbers for you. However, it is much simpler and less expensive to just run out to an auto parts or farm store and grab this stuff off the shelf.
Bobcat Oil Drain Hose/valve makeup for the Kawasaki Engines
1. 4164251 VALVE-OIL DRAIN
2. 4164252-001 FITTING-3/8NP TO BARB Fitting
3. 12” x 3/8” Clear
4. 48412-01 Hose Clamp to hold the hose alongside the top of the engine.
5. #6 Hose Clamps (2)
The above numbers are from the Bobcat CRZ parts manual.
However, all you need is:
1) 3/8” NP brass fitting to 3/8” barbed hose connector (Advanced Auto Parts) $1.79
2) 12” 3/8” clear PVC or neoprene fuel and chemical resistant hose. Any farm store, $1.19
3) #6 Hose Clamps, (2) Any store with hose clamps, 55 cents each. $1.10
4) 3/8” Hose end valve (plug) Brass:

I'm going to do this to all three of my mowers.
I'm going with all brass and use a balloon over the hose valve end after draining and returning the hose to the home position next to the engine cover.
