Is an electric tractor cheaper to run than diesel?

Usually, because electricity per hour of work costs less than diesel and there is no engine service. The exact saving depends on the job, your tariff and hours worked, so ask Farm Sathi to calculate it for your farm rather than relying on one number.

Can an electric tractor do a full day's work?

The WB 820 runs 3–8 hours and the WB 824 4–10 hours per charge depending on the implement and soil, and recharges in 2–6 hours. Many orchard days are covered on one charge; a lunchtime top-up covers the rest.

Does an electric tractor have enough torque for a rotavator?

Electric motors deliver full torque from standstill, which suits rotavators and cultivators in the small-farm class. Heavy tillage on large fields still belongs to bigger machines.

Electric vs diesel tractor for orchard work: what actually changes

In an orchard the tractor works slowly, stops and starts constantly, runs beside people and sprays under a canopy. Those are exactly the conditions where an electric drive is strongest and a diesel engine is weakest. On open fields with long days of heavy tillage, diesel keeps its advantage in range and refuelling speed. Here is the comparison job by job.

Side by side

	Electric (Farm Sathi WB class)	Diesel (same HP class)
Torque at low speed	Full torque from standstill; no clutch slipping in soft soil	Needs revs; clutch and gearbox wear in stop-start work
Noise and fumes	Near silent, no exhaust: work beside pickers, inside polyhouses, at night	Noise and exhaust in a closed canopy
Energy	Charged from mains or solar; cost set by the tariff	Diesel bought, stored and carried to the field
Maintenance	No engine oil, filters, injectors or clutch plate	Scheduled engine service; more parts to fail
Working hours per fill	3–10 hours per charge depending on model and job; recharge in 2–6 hours	A full day on one tank; refuel in minutes
Heavy primary tillage, large fields	Possible in the small-farm class; large fields need bigger machines	The established choice
Autonomy and remote control	Built in on the Autonomous Electric Mini Tractor	Retrofit only

Running cost: how to compare it for your farm

Prices change, so a fair comparison uses your own numbers. For diesel: hours worked per year × litres per hour for your tractor and job × the price you pay. For electric: hours per year × kilowatt-hours drawn per hour for the same job × your tariff (or near zero for solar). Add service costs for each. Ask Farm Sathi to run this calculation for your own farm during a demo; a sprayer in citrus and a rotavator in black soil give very different answers, so no single headline figure is honest.

Where diesel still wins

Fields far from any power supply, with no solar.
Long transport runs on roads with a loaded trailer.
Heavy primary tillage on large, open fields that calls for 45 HP and above.
Operations that cannot pause for charging and have no second machine.

Where electric wins clearly

Orchards, vineyards and plantations: spraying, mowing, light cultivation, hauling within the farm.
Horticulture and protected cultivation.
Farms with solar generation.
Any job where the next step is remote or autonomous operation.
