Choosing the right new vineyard tractor is an important decision, given the major capital outlay.
The German news site Top Agrar says research by Fendt indicates that the energy density of currently available batteries would not suit high horsepower prime movers.
Fendt director of research, development and purchasing, Heribert Reiter, says tractors up to 68hp (50kW) can typically use batteries to run for one to four hours depending on the task.
Calculations show that a 250hp (180kW) tractor running for 10-12 hours a day at about 50% capacity would need a massive battery.
A capacity of 800kWh would be required, taking up about 2 cu.m of space and weighing about 6 tonnes. And a 395hp (290kW) unit would need a battery of at least 1700 kWh requiring 4 cu.m and could weigh up to 12 tonnes.
Fendt also reports its new 700 series -- its most popular range -- will probably appear at Agritechnica in November.
It will include a new multi-function joystick with added functions such as a revamped cross-gate lever with forward/reverse shuttle control, and extensive colour coding to ease operator use.
The tractors will also have three display options with a central computer. A 9-inch steering column mounted, tablet style display will offer machine features and road travel information. A 12-inch terminal is mounted to the right-hand armrest, while an optional 12-inch display is located just below the roof lining on the right-hand side of the cabin.
The tractors will eventually have the FendtOne system that will connect on-board information with, say, farm offices or mobile devices, all with consistent appearance and layout.
