well at last i have managed to finish this. the 6600 was the first deere we had on the farm after one of the deutz's had a fire in it. we kept it for 4 years before trading it in for one of the first new 6620's(the 6600 was about 2 years old when we got it but only had 1000 hours on it).
anyway always wanted a model of one but nobody ever made them so thought i would build one. there is only 2.5mm in hieght difference and about 10mm in 5 mm in lenght difference.well have taken a few pics any questions or comments welcome.
