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 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!
