Sensor-1 at Princeton,Kansas built this Radar GPS system for me...I picked it up yesterday afternoon in Princeton and installed it this morning..My tractor hit 16.2 mph down the driveway in pulling gear..I will try and stay at 12-12.2 mph when pulling unless I'm the first hook....I get to try it out tomorrow evening at the Bates County Fair MSTPA pull at Butler,MO...They have a brand new longer track as their old one was only 300 ft long..I'll report back on here the day after the pull....If I can't stay under 12.5 mph with this then its time to retire or move to a no speed limit class..
