Final drive and differential lock
The 5E Series final drive is a heavy-duty planetary type. It has features that reduce the need for adjustments, prevent the entry of external contaminants, and ensure the best distribution of forces in the internal components, which gives more strength and durability to the tractor's rear axle.
Mounted final drives
Differential lock
The final drive can have the differential locked by a pedal positioned to the right of the operator's seat, allowing for simultaneous clutch engagement. The differential lock prevents relative movement between the two rear wheels and distributes equal power to both, preventing one of them from turning faster than the other. This option should only be used in extreme slippage conditions to increase operating efficiency. The differential lock has automatic engagement when traction in both wheels is equivalent.
NOTE: The differential lock must not be used on bends or at high speeds.
Front axle
5E Series models are equipped with front-wheel drive (known as 4x4). They have hydraulic steering with an exclusive pump for greater accuracy, comfort and operator safety.
The front axle improves front-wheel drive efficiency by reducing slippage. Tractors equipped with front-wheel drive have a greater working capacity in adverse conditions, such as low-grip land. The front-wheel drive axle of the 5E Series models has a mechanical transmission and a 55-degree angular pitch, allowing for excellent steering. In addition, the front-wheel drive axle has a central pivot system with 20 degrees of oscillation, which allows the tractor to better follow the land surface, resulting in greater traction capacity.

Engine
John Deere agricultural engines were designed to develop high torque with low rotation, providing quick response to common implement work variation and resulting in excellent performance for both low maintenance and long work life.
The 5E Series engines are factory-equipped with more power and efficiency and are certified for MAR-I emission regulations. The 5060E/5060EN/5070E/5080E/5080EN models are equipped with 3-cylinder engines. The 5078E and 5090E models are equipped with 4-cylinder engines, all meeting the emission regulations.
In addition to the changes to comply with the MAR-1 regulations, further changes were made to increase engine efficiency and economy, taking 3-cylinder engines to 375 hours of oil change interval and 4-cylinder engines to 500 hours.

PTO shaft and drawbar
PTO Shaft
All 5E models have PTO and Economy PTO (E-PTO), which have been improved to maintain a rotation speed of 540 rpm while allowing the engine to work more efficiently, resulting in reduced fuel consumption.
PTO speeds and respective engine speeds: Standard
- PTO: 540 to 2100 rpm
- E-PTO: 540 to 1600 rpm
With this improvement, the PTO application has become 5% more fuel efficient than previous tractor versions (rpm in previous versions: 2400 rpm for Standard PTO and 1700 rpm for E-PTO).
PTO output shaft
Understand the Economy PTO output shaft (E-PTO)
What is E-PTO?
E-PTO is a feature that allows the operator to operate the PTO at 540 rpm, but at an engine rpm lower than the standard PTO rated speed. Depending on the transmission, the 540 E-PTO setting could reach 1600 rpm. The E-PTO allows for reduced fuel consumption, as well as reduced vibration and noise levels during implement coupling.
How it works
On John Deere tractors, switching from 540 (standard PTO)/540E (E-PTO) mode is similar to shifting gears on the transmission. When engaging the 540E mode, the operator changes the gear reduction ratio, keeping the PTO spinning at 540 rpm, but reducing the engine rpm. When the operator shifts the PTO into standard mode, a different gear reduction ratio is used to operate the PTO at 540 rpm with increased engine rpm.
To operate in economy mode, the E-PTO must be engaged before the accelerator, until the engine reaches the proper rpm indicated on the instrument panel.
When to use E-PTO mode
The 540E mode is ideal for many applications including mowing, baling and tilling. This mode cannot be used with the maximum PTO power indicated in the product specifications. For operations that require full power, the tractor must be operated in standard PTO mode.
Detailed engine speed information for each of the standard and economy PTO options is available in the tractor operator's manual.
