I can help on the first part. I have had all the TR's,(70,95,96,97,98,and now 99). The TR99 with 30' flex head in soybeans will do what the TR 97 I had with a 25' flex head would. Some of the drives are build better and stronger on the 99. The cab controls is nicer on the 99 also. lots of other little things that made a 99 a better combine than the 97 was but still all of the good things was the same on both of them. If you liked your 97 you would love a 99. People tell me that the CR's are a step above the TR's, have never seen someone go back to a TR after they had a CR.
