Comprehensive mechanical inspection checklist
- Engine compression and blowby: Start the engine from cold; remove the oil dipstick or breather cap to check for back-compression or exhaust smoke venting from the crankcase.
- Exhaust smoke diagnosis: Blue smoke indicates worn piston rings burning oil; dense black smoke points to faulty fuel injectors; white smoke suggests unburnt diesel or coolant leaking into combustion chambers.
- Hydraulic lift under load: Mount a heavy implement (like a cultivator or rotavator) and lift it to maximum height; turn off the tractor to ensure the hydraulic arms do not gradually drift downward.
- PTO and clutch operation: Test power take-off (PTO) engagement under load, and check clutch pedal free play and engagement bite point.
- Tyre tread depth: Inspect rear tyres carefully; replacing a pair of large tractor tyres represents a major expenditure.
Evaluating hour meters and operational history
Examine the analogue or digital hour meter reading. A tractor operating under 3,000 to 4,000 hours with routine oil change history generally retains significant service life. Verify the meter reading against physical wear indicators like worn brake pedal ridges, steering play, and footboard paint wear to identify tampered meters.
Legal verification and RC transfer on Vahan
- Verify chassis number and engine number stamped on the tractor frame against the original Registration Certificate (RC).
- Check vehicle history on the Ministry of Road Transport and Highways Parivahan Vahan portal (parivahan.gov.in) for pending challans, blacklisting, or active bank hypothecation.
- Obtain Form 29, Form 30, valid insurance, PUC certificate, and Form 35 bank loan clearance NOC from the seller prior to completing final payment.
