This 306 horse mt765 pulls the disc 1.5 - 2 mph hour slower than a 450 hors stx QT.

Averages 5.0 mph with 1 g/acre deisel consumption.  Quad takes more.    The guidance is set up for 25' and seems to work just right.  

Its a nice setup, went from a 9390 to quadtrack and started to blow bearings every 350 acres.........We think its because 7 mph is too fast.   Didn't blow a bearing this year at 5 mph.

Good Luck
