If you're looking for more horsepower, check out John Deere's four new 7030 series large-frame tractors ranging from 140- to 180-PTO hp. The 7630 offers 140 hp, the 7730 152 hp, the 7830 165 hp and the 7930 180 hp.
The 7030 series feature a cleaner-burning 6.8 liter PowerTech Plus engine with a rated speed of 2,100 rpm, which delivers a 40% torque rise.
The new engine also includes a Variable Geometry Turbocharger (VGT), cooled Exhaust Gas Recirculation (EGR), and four valves per cylinder head. “This technology allows us to meet cleaner emissions standards,” says Ron Schwertner, division manager, marketing, at John Deere Waterloo Works.
In addition, the new optional Intelligent Power Management provides up to 30 additional engine horsepower for use in transport or non-stationary rear PTO operations.
Three transmission options are available on the new 7030 series. The 16-speed, 19-mph PowrQuad Plus transmission is the base model. It features clutchless, push-button gear shifting in each range.
If you want more automatic ease or faster transport speeds, go with the AutoQuad Plus or Infinitely Variable Transmission (IVT) at a 25 or 31 mph transport speed.
The AutoQuad Plus allows you to manually shift gears or program the tractor to automatically shift speeds within each range using the CommandCenter. With the auto mode activated, whenever the engine load increases and rpm's decrease, the transmission automatically downshifts to maintain optimal engine rpm and ground speed.
The IVT transmission can be adjusted infinitely from a creeper speed as slow as 165 ft./hour (0.03 mph) up to maximum transport speed without clutching.
An optional FieldVision HID lighting package is available, which includes extra roof lights and high-low road lights. The new models also come with a standard Category 3/3N three-point-hitch which provides a 10,050-lb. lift capacity.
John Deere also introduces three new 6030 premium series utility tractors. The model 6230 has 75 PTO hp, the 6330 has 85 hp and the 6430 has 95 hp.
The new models offer two John Deere PowerTech engines, depending on operational needs. The PowerTechE two-valve engine is designed for low hour use and/or light-duty applications such as medium PTO work and light cultivation and spraying. The PowerTech Plus four-valve engine delivers a faster torque rise, increased lugging power and better fuel economy than the engines they replace.
“This new technology, tested and used in larger horsepower tractors, will perform for long hours in heavy-duty applications,” says Al Mennenga, product manager at John Deere Waterloo Works.
And like the 7030 series, three transmission options are available with the 6030 series: the PowrQuad Plus, AutoQuad Plus and the Infinitely Variable Transmission (IVT). The PowrQuad Plus features 16 forward and 16 reverse speeds with a transport speed of 19 mph. The AutoQuad Plus features 24 forward and 24 reverse speeds with a 25 mph transport speed. The deluxe IVT offers up to a 25 mph transport speed.
To top it off, a new premium cab has been added to the 6030 series. “Visibility has been improved and we've even added space for a field office computer or refrigerator,” says Mennenga.
