I was able to look at the 5420 this weekend. It is a 2004 model with 9F/3R, 4WD, Canopy, brush guard, joystick, extendable draft links and rear work light. Unit has 430 hours. Tractor seemed tight and everything works. Very clean. Much larger than the 5105. I like this tractor. Dealer is taking a 521 FEL in on a trade and offered to include it in the deal since I want a loader. Price out the door including loader $26,200. He also is going to get a 1999 model 5510 in on a trade soon. This unit has the power reverser transmission, but is 5 years older and has 2300 hours. I know the reverser would be more handy, but from pictures I saw the 5510 looked like it had been worked pretty hard. It had a 541 self leveling loader and was $21,000. Strongly leaning toward the 5420. Supposed to get some pictures of the 521 loader early this week since it is not currently on the yard to view. Offered $14,500 in the trade for my 2004 5105 2WD with 512 loader. Any opinions or suggestions?
