I am in the exact same boat. I am going to be looking hard this winter at upgrading to either a 760 or 780. I want the wide body machine for the larger cleaning area in canola, and I want the tracks because of stability and fewer chances for flat tires. Also, I am sick and tired of broken bolts on my duals. I know they have fixed the issue on the 700 series, but I am now gunshy. We have replaces 4 sets of wheel stud bolts in 3 years, and I have a broken bolt on the other side right now. That will be 5 times in 3 years that we have had to fight those tires on and off! Anyways, I think there are enough improvements recently (i.e. cruise pilot and cemos auto) to justify a new or one year old machine. The increased acres a person can cover compared to a 580R should be significant.

I traded 570 for 740tt this year. Went from singles to tracks. They are amazing. So smooth in field, no sinking, great ride header stays so even too. Did a lot of cutting poor peas at 8.2 mph. No way tires would let you cut that fast. 25 mph on road is nice too. Have done 2300 ac without cleaning rad or air filter. Great design change there. Bit more horses nice, but burning an extra litre per acre of diesel New sieves nice. Faster unload nice. Tracks are worth the cost!

Do you mind me asking where you are from rodd? What other crops are you harvesting? Is power the limiting factor on the 740?

I don't think power is limiting factor, it is usually how fast crop will feed or how much is going over. Cutting 60 bu Pasteur now. 4.2 avg speed 36', I have fan cranked to hopefully blow out fusarium so any faster and sieve monitor shows losses. Check ground and can't find any though. Very seldom have to slow down for engine warning. Even the 570 had enough power.

Thanks for the response. Talked to a guy the other day and he claims loss monitors are too sensitive. He goes balls-to-the-wall with a 780, it's quite the show.:D
