First load on a new truck - Red Winter Wheat - with 40' Hopper, 5th wheel is fixed, Gross 77,360 - Steer 10,260 - Drive Axle 33,360 - Trailer Axle 33,720. I've got 3 holes available to move the 5th wheel forward; distance from center of bolt to center of forward hole is 6". Wheel Base 198", Distance Front Axle to Kingpin 15' 2, Kingpin Rear Axle of Trailer 36' 4" current measurements. I'm thinking move it the full three holes. Opinions, suggestions welcome.

Just wondering have you considered how much fuel you have on 100 gallons of diesel weighs 720 lb so if you have 200 gallons on you got 1440 lb of weight but fun anyway how much fuel do you have on when you have this load

Kevin - Couldn't change the wieght on the front axle by more than a 100 lbs. adding/subtracting from hoppers. I moved it ahead the three holes; 15/16" Socket 1" Drive, with same size wrench, and about an hour of work. Hard part was under the middle of the 5th wheel had to use two wrenches, a pipe wrench as an extension works wonders for us old guys. Will be loading Canola Meal on Thursday, I shall let you know the results.

The center of the fifth wheel or head , should be just forward of the center of the tandem , end of story , 6 inches is good 8 inches is to far forward , this offers a better ride and prevents the rear rear axle tires from wearing much faster than the the forward rear axle , like the man said , load more on the nose of the trailer ,

Not good to use stretched bolts for something as critical as that. Good luck

Most will transfer 200-250 pounds from drives to steers per hole on the 5th wheel. Set back steers pick up weight better than forward set like those on long wheel base trucks.

I couldn't figure out why my rear axle tires wore nearly twice as fast as my front axle. My truck has a fixed plate way over 6 inches. Its nearly on top of my front axle. I have a slider Im gonna put on when the weather gets warmer. Just curious would a pusher fix this?
