The John Deere 7930 is an easy tractor to operate. The controls are where you expect them to be, visibility is excellent, it’s quiet, the front suspension does a good job smoothing out the bumps, and you can just jump in and drive it.

Engine and power

The 7930 runs John Deere’s 6.8-litre power tech engine with common rail fuel injection, four valves per cylinder, 10 percent power bulge and a host of other high-tech features.


The 7930 has the 50km/h version IVT (Indefinitely Variable Transmission). Driving an IVT is similar to a hydrostatic transmission without needing full revs. A lever on the armrest sets the speed, a selector on the dash sets one of three modes: 1 for PTO work or anytime you need the engine revs matched to the throttle setting; 2 for heavy draft or towing work; and 3 for light work such as transport, drilling, etc.

The fuel savings must be considerable over the life of the tractor.

The 7000 series also have the option of the power quad or auto quad transmission for those that prefer a semi powershift type transmission.

Inside the cab

The cab is well laid out and quiet. A combination of no dash and a narrow bonnet gives excellent forward visibility, while the curved rear window allows the full width of the six-metre drill to be seen.
All the commonly used controls are easy to find with John Deere’s command arm. An A pillar display provides information found on a normal dash setup and a console to the right of the seat houses all other controls.

The cab has climate control air conditioning and is wired for John Deere’s Greenstar system.

Also fitted is the "active seat" option, which gives the driver an excellent ride.


These are a closed centre, pressure and flow compensated system meaning that there is still plenty of flow even when the IVT’s brain throttles the engine back.

Controls for the remotes are electric over hydraulic and are mounted on the command arm. Settings for the remotes such as flow are controlled on a digital display on the right-hand console. The system also has a headland management function.


The 7930 is equipped with front suspension and it does a good job.


Access to the engine is easy, with a rear-hinged lift-up bonnet allowing easy cleaning of the radiator area.

Engine oil changes can be extended to 500 hours using John Deere oil and filters.

The owner says…

Simon Broom has been very pleased with how his 7000 series tractors have preformed. For their horsepower the 7920s and the 7930 are quite manoeuvrable tractors and are ideally suited to his work. He says they perform well on the hill discing and on the silage stack (one of the 7920s has a JD loader fitted).

Simon admits that he ticked a lot of boxes when choosing options for his new tractor, such as electric mirrors, front links and PTO, and air brakes so he can use heavy trailers behind the tractor, and the leather seat.
