2 Great Dane Chariot 61 inch zero turn mowers -- what year are they?

[CJWJ]

I've got two Great Dane mowers and cannot figure out what year they were made. Model and serial numbers are below. From the parts catalogue, it seems like serial numbers for this model run from 455000-460999. Any help is much appreciated! Looking to list these for sale. Tires are flat, and one may not be running currently. The other takes a special touch to get going.

MODEL: GDRZ25KHE
S/N: 234135

MODEL: GDRZ25KHE
S/N: 133067

Do you figure the engines are original? You might be able to get a model year that way, or close?
