Here is a John Deere 6910 I have just finished for a customer I built one about 2 years ago and vowed never to do another Anyway this guy was quite persuasive and not in a hurry so when I was in the right frame of mind I started cutting up green tractors :o
The conversion involves cutting in half two ERTL jd 6410's, one right next to the cab and one 12mm from the cab then stick them back together and fit Siku 6920 wheels, front axle and rear linkage.
Very nice but very time consuming hence very expensive ;) And no I won't make another :( :(
