I borrowed a 4650 once. Put my 4x16 rollover plow on it.Wound up it had more power than my 1256.At low rpm it was a dog. Fell flat on it's face. Had to leave the throttle wide open at all times,use the powershift to turn and slow down.It had no low end torque. The 1256 on the other hand,you could back the off the throttle down to an idle to slow down and make your turn.. Then push it open and it would go.All kinds of low end torque.BTW,the 4650 used about twice the fuel of the 1256.Even the 4040 I bought new in '80 used more fuel than my 1256 does now.And my buddies 4010 would out pull it.I think I'll stay with my red ones.LOL

Today's Featured Article - Restoring a John Deere 2010 Diesel Tractor - by Jim Nielsen. Following seven years working in California's Silicon Valley, my wife, baby son and I moved back to Australia to retire. We bought a small 'farm' of about 50 acres near Bendigo, in the state of Victoria. I soon found that it would be very useful to have a tractor around the place for things such as grading our long drive and brush-hogging the fields. I was also embarking on planting 1000 eucalyptus trees, and hence I would need a ripper, small disk plow, sprayer etc. to get these things accompli ... [Read Article]
