AutoTrac cuts tractor costs

JOHN DEERE claim 10 to 15% lower operating costs for their tractors when fitted with their AutoTrac automatic guidance system.

AutoTrac increases the accuracy of any straight or curved line operation in the field. The company’s 8030 Series tractors are now being delivered from the factory with AutoTrac fitted, at no additional charge.

This means they have all the internal hardware required to operate the system installed as standard during the assembly. Customers only have to add and activate a GreenStar Monitor and StarFire iTC GPS receiver.

“Easy operation and productivity boosts have significantly increased demand for the guidance system, according to John Deere.

A John Deere 8430 tractor recently set a record as the most fuel-efficient row crop tractor tested at the Nebraska Tractor Test Lab.

Results for the 305 horse power 8430, which was equipped with an Automatic PowerShift transmission, were achieved with the new Tier 3 compliant nine-litre PowerTech Plus engine tested at a 100% PTO load and at rated engine speed. The tractor consumed only 228g per kWh, 8.8% less than 8430’s comparable predecessor, the John Deere 8520. The 8030 Series of 225 to 330 horse power tractors were awarded the Agritechnica gold medal for improved fuel efficiency in 2005.

New Tier 3 engine technology is designed to produce higher torque at lower engine speeds, leading to better fuel economy and higher productivity in the field.

The Nebraska Tractor Test Lab advises that a 100 horse power tractor operating at a moderate load level will burn about five gallons of diesel fuel per hour. By throttling back 20% and shifting to a higher gear, you can expect to burn about four gallons of diesel fuel per hour, and still do the same work.
