FOR MORE THAN 50 YEARS, we’ve not only been building application equipment, we’ve been riding along with, and listening to, the professional applicators who use it. And it’s been their guidance that’s helped us engineer the best machines you can buy. The new TG7300B/TG8300B is no exception. It’s more than just a Tier 4 Final engine; it redefines the standards for how efficiently an applicator can work. Because we manufacture our own engine and transmission, they are designed to work perfectly together. For more power to the ground, more torque and better fuel efficiency. Our comfort-enhanced cab is the only one in the industry built specifically for application. And we offer more liquid and dry systems than anybody, because we understand that every farm, field, climate and growing trend is different. So if you’re truly serious about precision application, there’s no better machine with which to trust your business.
TG7300B & TG8300B ENGINE TECHNOLOGY AT-A-GLANCE
• Dual-stage turbocharging and inter-stage charge air cooler (iCAC) – Dual-stage turbocharging increases low engine speed torque, improves fuel consumption and decreases exhaust temperature.
The iCAC provides thermal reliability for a more efficient, cleaner fuel burn.
• Diesel Oxidation Catalyst (DOC) - The DOC reduces particulate matter in the exhaust stream by 20-50%, depending on operating conditions.
• Pump and injection system - This system reacts to the emissions output of the engine and continuously varies the amount of DEF added to the exhaust stream.
• Selective catalytic reduction (SCR) chamber - The DEF-treated exhaust enters the SCR catalyst chamber. There it reacts with the catalyst and NOx and is transformed into harmless nitrogen gas and water vapor.
• Cooled exhaust gas recirculation (cEGR) - A small amount of exhaust gas is cooled and recirculated as needed into the air intake to reduce the amount of raw NOx and limit the consumption of DEF to meet emissions standards.
• DEF tank – The 15-gallon DEF tank is conveniently located between the fuel tank and entry steps. It features a heating coil to circulate engine coolant to prevent freezing and to thaw frozen DEF during cold-starts.
Peak torque to the ground is quickly and smoothly produced, and consistently maintained, at engine speeds as low as 1500 RPM.
A PURPOSE-BUILT ENGINE
Our engine is engineered specifically for off-road, ag use. Others use on-road engines in their off-road machines.
Each engine rotating group is precision-balanced to within one gram for less vibration, less wear and tear and much longer engine life.
This powerful, smooth-running Tier 4F engine uses less fuel and less DEF than the engines in comparable machines in its class.
LONGER SERVICE INTERVALS
Maintenance intervals are longer, so you’ll spend more time in your customers’ fields.
WHY THE CVT IS BETTER
• Conventional-shifting transmissions are limited by the number of gears. The CVT fills in those gear gaps, so you choose your speed, not a gear. Up to 41 MPH at virtually any engine RPM. Field speed is smoothly maintained for the most precise application.
• The advanced TerraGator Management System (TMS) maintains an intelligent, electronic link between engine and transmission allowing you to choose an exact ground speed, engine speed or combination of both to fit conditions. The TMS ensures that firm, continuous traction is applied, minimizing wheel slip and reducing ground disturbance.
• Because the CVT and engine are always synchronized with terrain and load demand, our applicators are designed to deliver optimum fuel efficiency.
• There are no clutch packs in the CVT, so service intervals are longer than a powershift or automatic transmission. Plus, with the fewest moving parts of any mechanical transmission in the industry, you get better reliability, longer machine life and greater resale value.
• A separate hydraulic reservoir isolates it from other hydraulic systems and minimizes the chance for contamination.
BETTER AXLES. BETTER RIDE. BETTER YIELDS.
• Freewheeling front axle design has a rated capacity of 14,000 pounds (6,350 kg), while the three-piece drive line running from the transmission to the rear drive axles uses maintenance-free universal joints and hanger bearings, reducing maintenance and service time.
• Rear axle drive is equipped with air cam-actuated drum brakes with automatic slack adjustors and spring brakes that adjust to maintain proper brake setting and reduce maintenance.
• One-piece horizontal frame rails are a single length of high-grade, low-alloy steel. The rectangular, tubular 4 in. x 12 in. (10.16 cm x 30.48 cm) beams are cold-formed and internally pressurized, reducing metal stress to allow for flex during field operations. Some competitors cut and re-weld their rails, potentially creating weak spots.
