Hi, keloz.
What rock have you been hiding under - haven't heard from you for a while.
Guesstimate - around 24 Tonnes. Some people are gonna quote you for a D7E with bull blade, tilt cylinder and ripper with not much understanding of how much us DowNunda folks valued our heads when clearing timber - - - IF you get my drift. but it does pose a 'kwestyun' - is the canopy wunna rounded pipe frame scrub canopy types or a full length serious TIMBER canopy?
The D7F was close to two tonnes lighter with the six-banger donk - if my aging memory serves me rightly.
LOTZA people reckoned it was step backwards in the 7F with 2,000 RPM needed to produce the same power that the E produced with the four-banger at about 1,440 RPM but the F was a much nippier machine. But it did miss that weight in the front - - - - until we hung 2 X 4 foot square slabs of 1" thick steel plate on the front face of the blade for push-loading scrapers.
Just my 0.02.
