So many model numbers, it all gets confusing. But, from looking at the sears website, it appears that 287xx are 2007 models while the '08 model numbers are 288xx.
Differences I saw when shopping are noted in my "intro" thread:
I have an 07 DGS 6500 #28746 with a Kohler and a Hydro-Gear 3000. My tractor was made in Oct 07. So go figure. Red 07 DGS 6500's have B&S, Black one's like mine have Kohlers, I do believe the 28750 is the red one.I'm not sure, what the model number is for the '07. I'm assuming its 28750? I found it referenced in a couple of threads from last year, and doesn't come up on Sear's website. According to the website, the new number is 28746.
So, if above is correct...I think the engines are different. The 07' has a B&S ELS in it, and the 08' has a Kohler Courage Twin
Both should have a Tuff Torq K66, however some of the 08' models come with a Hydro-Gear 3000. Only the 28746(2) 08' model comes with a K66. All the other 28746 models appear to have a HG 3000. More info on the K66 vs 3000 here.
Other than that.. here's the manuals for both the 07' and 08'
On a side note, with the manuals. I noticed the 28750 manual was written in Jan '07, and the 28746 manual was written in Oct '06. Odd, but the Product Specifications on page 6 match the engines for each model.
Hope that helps.
Maybe the frames are the same, but looking at the diagrams side by side the back of the frame does look different. The part where the fender bracket appears to fit on.Sorry for spreading lies. I was looking at the 287460 not 288460 when I made the statement they had different frames.
