Abstract: A tractor that can pull a wide variety of equipment such as that for tilling, seeding and fertilizing of field crops. The equipment can also include reservoirs for containing large quantities of seeds and fertilizers such as liquid manure. As tilling and fertilizing progresses these materials as dispensed changing the weight distribution on the tractor. The change can be compensated for during use by sensing weight and adjusting the position of the machine connecting structure in response thereto, such as a fifth wheel of the tractor, in real-time, to generally equalize weight distribution.
