WildBuckwheat - 6/28/2014 16:43 A powershift does not just burn X amount of fuel. If 95% load is 15 gallons per hour it won't use that much in the 70% load areas of the field. If it tried to pump that much fuel into the engine with 75% behind it the engine would rev to 6000 and explode. Thats why tractors have governors instead of throttles. In the lighter areas of the field the powershift engined tractors engine will still be spinning at the same rpm. As long as the CVT tractor isn't doing PTO work the engine will drop back and the transmission will push on to maintain forward speed at lower engine revs. Most of the time the powershift tractor will be in a gear a little higher or a little lower than ideal. The CVT is always going at the right speed, any parasitic losses will be made up for because of this. | 
CVT and IVT the same?
