| Looking at a new S670 considering pro drive vs 3 speed transmission pro and cons on pro drive? We have an 8 row chopping head and when conditions allow like to run 7 - 7.5 mph. We have a 9770 now with 3 speed. My understanding is they have slowed down 2nd gear in that transmission, maybe to about 6.7 mph. Have also heard pro drive takes more Horse power that maybe a 670 can't afford to lose ? I guess anyone out there know for SURE how fast there 670 goes in 2nd gear ? | |
