I have a L3940 four wheel drive Kubota. I checked the toe-in of the front wheels yesterday and found that they needed adjusting. Toe was "0" to just a little bit "out". Operators manual calls for 1/16" to 5/16" toe-in and the Work Shop Manual calls for .08" to .300" which is approx. the same. The L3940 is adjusted by turning the tie rods on each side. I noticed that there was more thread showing on one side than the other but I accepted that the factory had the original setting correct and went ahead and adjusted both sides equally for a toe-in of 5/32". A question entered my mind later on. Since each wheel is adjusted by its own tie rod, how do you know that each wheel by itself was pointed straight forward with no toe when I first started? I know I got "0" toe-in on my gage when I started but how do you know the two tires were pointing straight forward? Is there a way you could tell if a tire and wheel is pointing straight forward with no toe in relation to the tractor? That way you could set both tires each by itself with "0" toe for a starting position and then adjust each equally to get the necessary toe-in. I know there is a possibility that I am not understanding this whole procedure in regards to the geomertry involved so if there is anybody that has some experience with it please set me straight.
