The John Deere 1470 G
engine ( in European models ), the 1270G and 1470G harvesters deliver 10 % lower fuel consumption from previous models .
The increased output is particularly notable in the 1270G 6-wheel machine , which now has the same power as the 1270G 8-wheel machine ( 200 kW versus 17 kW ). The torque has also increased by as much as 17 % in the 6-wheel machine and 5 % in the 8-wheel machine . Equipped with a completely new control system , the Timbermatic H-16 , features userfriendly control modules and wiring harnesses .
“ The noise level in the G-Model is much lower and the engine runs much more stably even at lower RPMs ,” says Frank Mäder , a John Deere customer based in Germany .
“ The engine has more power and doesn ’ t stall , not even when processing , driving and boom movements are done at the same time . Also noteworthy is that the boom can be controlled even more accurately than with IT4 machines , thanks to the new CAN design and new controllers .”
The Processing Power Control ( PPC ) system in the 1270G and 1470G harvesters has three different power levels to choose
from based on tree size . The PPC system anticipates the engine load and responds with the right power increase , which in turn improves fuel economy .
The cabin of the G-series harvesters is designed to maximize operator comfort . The cabin adjusts automatically to boom movements while the automatic levelling functions absorb terrain changes . This offers significant improvement in machine productivity and reduces vibration by as much as 50 % during operation .
“ The cabin offers a superior operating comfort ,” says Janne Sipiläinen , a customer from Finland . “ The usability is in a class of its own . The cabin levels itself and rotates automatically towards the direction of the work and with the boom , so you are always in a good working position .”
1270G harvester The John Deere 1270G consumes significantly less fuel than its predecessor , but boasts even more power . The increased output is particularly large in the 6-wheel machine , which now has the same power as the 8-wheel machine – 200 kW instead of the previous 170 kW .
“ After the first tree went through , I didn ’ t miss my old 1270E harvester ,” says Roland Salo , also from Finland . “ With this machine it ’ s easier to produce the same cubic meters of wood in a shorter workday than before . This was a good investment .”
Additionally , the 1270G features

Roland Salo , John Deere customer new control modules and wiring harnesses . The high-quality connectors reduce disruptions and the new modules improve productivity on the jobsite . The combination of the 1270G with the H415 harvesting head has shown notable improvements in harvesting efficiency .
And the machine comes with PPC – a simple and easy-to-use solution to balance power and fuel economy in different logging conditions .
1470G harvester The 1470G is the biggest harvester model in the line-up . With many of the popular features found in the 1270G model , the 1470G is equipped with a bigger CH9 boom and a different front frame , tyres and bogie axles . Like the 1270G , operators of the 1470G have praised the machine ’ s power and torque improvements , citing consistent engine performance without drops in RPMs .
The geometric design on the 1470G CH9 boom provides increased stability and offers excellent accuracy and manoeuvrability . The operation of the CH9 boom has been made more efficient with the open loop Twin Pump Hydraulic System , enabling
