Willie (MBWW) sent a PM asking if I could take some pics of the two side by side. He has someone who can't 'see' the differences between the two. After the wonderful writeup he gave me here, I thought I might oblige. But I wanted to share this info with all of you. So here goes!
Both these tractors are 1981-1983 models & at first glance they look alike. But, studying them a bit, you can see major differences.
Full Frontal Pic:
The frame is much heavier on the FF! I guesstimate the GTV at about 400 lbs. The FF20 is 875 lbs from the factory.
One thing to consider here is that the GTV does have 26 X12 -12's on it and the fender pan has been raised 1" to give clearance for these tires.
The wheelbase for them:
GTV = 45"
FF20 = 48"
GTV = 29"
FF20 = 34.5"
Also, at the top of the grille (bottom of hood), the FF20 is 2" wider.
Here's a couple dash shots:
Willie, if more pics are needed, just let me know!
