Electric vs Diesel Tractor Testing: What Changes Without an Engine

Manufacturers coming to electric tractors from diesel often expect a completely different testing world. In practice most of it is familiar: the same institute, the same headline performance tests, and the same reports, subsidy rules and validity periods. What changes is what sits behind the drawbar: a battery and motor instead of an engine, and the standards that come with each.

The side-by-side

	Diesel tractor	Electric tractor
Test code	IS 5994, Agricultural tractors — Test code	IS 19262:2025, Electric Agricultural Tractors — Test Code (built on IS 5994:2022)
PTO, drawbar, belt and pulley	Yes	Yes, the same headline tests
Vibration measurement	Yes, with dedicated vibration standards in the FAD 11 family	Yes, named in the IS 19262 scope
Powertrain standards	Engine tests within the tractor code family	Automotive Industry Standards for electric vehicles, adapted for farm use
Exhaust emissions	TREM emission norms, tested on engine cycles	No tailpipe emissions at the farm
Benchmarks	Built on decades of tractor standards and test data	Electric-specific acceptance criteria expected to develop from IS 19262 test data
Institute	CFMTTI Budni	CFMTTI Budni, which has tested electric tractors since 2021
Testing time limit	75 working days (from 15 Aug 2022)	75 working days, the same tractor limit
Subsidy eligibility	Only tested equipment is eligible under SMAM	Same rule

What stays the same

The farm-performance tests. IS 19262:2025 covers PTO power, drawbar power, belt and pulley performance, vibration measurement, specification verification and inspection of components and assemblies.^[1] These are the tests that make a tractor a tractor, and they are why the electric code builds on IS 5994:2022 rather than starting from scratch. A buyer comparing an electric model with a diesel one gets measurements taken the same way.

The institute. CFMTTI Budni handles both. It tested the first-ever electric tractor at the institute in 2021,^[2] and it contributed to IS 19262:2025.^[1] Our first electric tractor test post covers that story.

The process and the rules around it. The tractor testing time limit of 75 working days, in force since 15 August 2022, doesn't distinguish by fuel.^[3] The SMAM rule that only tested equipment is eligible for subsidy applies to both.^[7] So do the tractor sample size (5 units) and report validity (3 years for the first commercial test, 5 years for each Batch Test after that).

What changes: the powertrain

A diesel tractor's power comes from an engine, and the tractor code family has standards built around measuring it. An electric tractor uses motors and a battery pack. The BIS release describes electric tractors as using "electric motor(s) powered by battery packs, instead of conventional diesel engines".^[1]

That is why IS 19262:2025 draws on "relevant Automotive Industry Standards developed for electric vehicles, suitably adapted for agricultural applications" as well as the tractor code.^[1] The release does not name which AIS documents are used, and we won't guess. Your copy of the standard lists its normative references.

What changes: emissions

This is where the two diverge most clearly.

Diesel tractors are subject to the TREM emission norms for agricultural tractor engines, and type-approval includes emission compliance on engine test cycles. The next stages are now arriving. MoRTH issued a notification on 6 March 2026 on implementing the TREM norms, phased by engine power band.^[4] The ICCT describes the TREM V stage as aligning Indian non-road norms for agricultural tractors with EU Stage V.^[5] Secondary summaries of the phasing disagree on exact dates, so take the dates for your power band from the gazette notification itself.

Electric tractors have no engine exhaust. The BIS release notes that an electric tractor "eliminates tailpipe emissions at the farm level", and also points to significantly lower noise and no operator exposure to exhaust fumes.^[1] Engine emission cycles simply have nothing to measure.

What changes: benchmarks

Diesel tractors have decades of standards and test data behind them. For electric tractors, the BIS release says the data generated under IS 19262:2025 "would also assist in the future development of acceptance criteria and conformity assessment schemes specific to electric tractors".^[1]

In practice, the measurement method is settled and the electric-specific benchmarks are still being built. Manufacturers testing now are contributing to that data. A thoroughly prepared first submission is good engineering and also helps set the reference point for the category.

A practical checklist for diesel makers going electric

1. Keep your tractor-testing playbook. Documents, sample size, the draft-report stage and validity planning all carry over. Our electric tractor testing guide covers the full route.
2. Add IS 19262:2025 to your standards library alongside IS 5994:2022, and read its EV-standard references. The IS 19262 explainer walks through it.
3. Rework your specification sheet for the electric powertrain. Specification verification is in the IS 19262 scope, so declare motor and battery details you can stand behind.
4. Settle the type-approval scope with CFMTTI Budni early. It is the one area where you should get the institute's answer rather than rely on diesel habits.
5. Price subsidy by PTO HP, as the SMAM bands do. See Electric tractor subsidy: the test report comes first.

Where we come in

Mapping a diesel testing playbook onto an electric tractor, and finding the few points where it doesn't carry over, is the work test process guidance covers. AgPro doesn't test tractors; CFMTTI Budni's engineers do. We help you arrive with the right code, the right documents and the right questions already answered.
