Based on a 4 speed gearbox with two or three ranges, the transmission is offered in 8+2 ,12+3, 8+8 or 12+12 speed configurations to cater for even the most demanding applications. All models of the 4E Keyline range have a top speed of 34 km/h, for safe, rapid transport by road.
With the addition of the optional creeper gear, 4E Keyline tractors are also ideal for very low speed applications, capable of ground speeds of just 500 metres per hour at maximum engine speed in the lowest gear.
The generously sized dry clutch with state of the art pedal linkage is comfortable and effortless to use, for setting off smoothly even when working with heavy, high draft force implements.
To extend the already impressive capabilities of these tractors in standard configuration, a special set of waterproof seals is available for working in particularly difficult conditions such as rice paddies.

The comprehensive PTO package equipping the DEUTZ-FAHR 4E Series Keyline is extraordinarily versatile, for outstanding productivity whether working with high or low power demand implements. In addition to the classic 540 rpm speed mode, the PTO is also available as optional variants with 1000 rpm, 540 ECO or 540 rpm reverse modes. The PTO is engaged and disengaged with a dual action dry plate clutch operated progressively with a practical hand lever, for starting even implements with high rotating masses smoothly and gradually.

The open centre hydraulic system is fed by a gear pump with a maximum output of 31 l/min (or 27 l/min on the 4045 E Keyline), and features 2-way (or, as an option, 4-way) rear distributors.
For superior comfort, all models are equipped with hydraulic power steering fed by a dedicated pump that is completely separate from the main pump, for impeccably smooth steering action even at low engine speeds and while the lift or hydraulic distributors are in use. The rear lift (with Cat. III three-point linkage) has an impressive maximum lift capacity of 1600 kg (or 1250 kg for the 4045 E Keyline), and is equipped as standard with the Easylift system.

The rear axle is available as “Light” and “Heavy Duty” variants. On 4-wheel drive versions, models up to 55 HP feature a Dana front axle; while 60 HP models are fitted with an original SDF front axle.
The possibility of fitting tyres up to 650 mm in diameter at the front and 675 mm at the rear offers impressive ground clearance, making 4E Keyline tractors even more versatile. The excellent agility of these tractors is the result of a compact a wheelbase - just 1950 mm for 4 wheel drive versions and 1920 mm for 2 wheel drive models - combined with an impressive steering angle (55° and 51° for two and four wheel drive versions respectively), allowing for very tight headland turns. A Girling brake system and a parking brake, both of which mechanically operated, ensure dependable stopping and holding power.

With every detail designs in accordance with the latest standards for ergonomics, the driver zone is comfortable and functional and offers excellent forward visibility. The all-flat platform facilitates access, while the adjustable driver seat, offered as standard, includes an effective mechanical suspension system adjustable to suit the weight of the operator. Intelligently organised controls and a modern analogue instrument cluster ensure that all the main operating parameters of the machine are clearly visible at all times, maximising productivity.
These tractors are available with a robust two-pillar rear ROPS structure and steel hand rails on the rear mudguards.
