Yanmar YM2000 serial number and more

[gdtractor]

I have a Yanmar YM2000 Diesel - LOVE IT!! but I can't figure out if it has a glow plug or not - it has the "glow plug" position on the switch! It runs AWESOME!!
Also, how would I find out how old it is - the number on the side says ym2000-04811

Here is a video of the tractor: http://youtu.be/2D5gmgyKoYI?list=UU7TY6oc3N-TD34WpzI3MzYg
My main concern is - WHAT YEAR IS IT? and DOES IT HAVE A GLOW PLUG?
If you can help .. I would appreciate it !

Thanks - Gary

I have one and if you take the breather cover off and look down inside while holding the key in the 'warm-up' position, you should see a tiny flame.

That's the way mine is anyway. It has an actual flame that warms the manifold.
