When vineyard slopes become too steep for traditional specialized tractors, safety takes priority—and that’s where rubber tracks come into play. However, metal tracks typically mean sacrificing comfort and road usability. Enter the Bcs Sky Jump K90, a unique semi-tracked tractor that overcomes both limitations with its innovative design
The Sky Jump K90 combines the best of both worlds: front wheels offer maneuverability and comfort, while rear rubber tracks provide superior traction and stability. The result is a versatile machine that doesn’t compromise on-road performance or operator comfort.
This cutting-edge design is not only available in the signature colors of Bcs’s three brands but also in a distinctive pearl-white livery, emphasizing its unique technological features. While other semi-tracked tractors exist in the specialty sector, none feature a steering system like this: four hydraulic cylinders control both the front axle and the central articulation of the exclusive “OS-Frame” chassis, enabling an ultra-tight turning radius of just 220 cm. This allows the tractor to pivot almost on the spot—ideal for switching rows without complex maneuvers, saving time and reducing labor costs.
Low Center of Gravity, Maximum Stability
Based on Bcs’s isodiametric platform, the Sky Jump K90 features a low center of gravity for safe operation on steep and challenging terrain—areas previously accessible only to full-track tractors. Unlike those, however, the Sky Jump K90 can legally drive on roads at speeds up to 40 km/h, eliminating the need for a trailer or flatbed truck.
On the road, it offers stable, precise handling, and its switchable all-wheel drive helps optimize fuel consumption. Even on steep cross-slopes, the front tires reduce the risk of rubber track derailment, a common issue with fully tracked systems. Conventional track systems rely on rubber blocks for traction, which can wear down prematurely and result in sudden loss of drive. BCS’s approach enhances safety and durability.
Cabin Comfort and Operator Safety: Standard
Operator safety is a top priority. The Sky Jump K90 comes standard with a Category 4 pressurized cab, which protects against gases, liquids, and particulates while providing automatic climate control. Despite its low-profile 185 cm height—perfect for tight orchard canopies—the cabin doesn’t compromise on comfort: it’s mounted on silent blocks for vibration isolation and features a suspended, adjustable seat, a customizable driving position, and an automotive-style suspended pedal system, including the clutch.
That said, clutch use is minimal thanks to the EasyDrive™ transmission system, which allows smooth, progressive gear engagement and automatic direction changes via a responsive control lever. The operator doesn’t need to manually use the clutch, brakes, or shift gears, boosting both ease of use and operational safety.
Hydraulics That Work as Hard as You Do
Efficiency extends to the hydraulics: an electronic joystick (optional) manages the rear three-point hitch and hydraulic valves. The system delivers up to 49 L/min of dedicated hydraulic flow (with a separate 33 L/min circuit for onboard services), ensuring top performance during field operations.
The rear lift (position and draft control available) offers a capacity of 2,700 kg, with an optional front lift rated at 800 kg, and up to nine hydraulic outlets between front and rear.
The result is a hyper-specialized tractor that shatters the limits traditionally associated with narrow-track and isodiametric vineyard tractors.
Under the Hood: Reliable Kubota Power
Powering the Sky Jump K90 is a reliable Kubota V3800-CR-T-EW03, a 3.8-liter, four-cylinder engine. Though capable of over 115 hp in Stage IV configuration, it’s currently calibrated to 75 hp at 2,400 rpm under Stage V emissions regulations. This detuning boosts reliability and flexibility, supported by a maximum torque of 305 Nm at just 1,500 rpm, with 80% of that torque available from just 1,000 rpm.
Turbocharged and fueled by a direct-injection common rail system, the engine is electronically managed for optimal fuel efficiency, delivering smooth and powerful performance across varied terrain and conditions.
