Sonalika GT 20 vs Powertrac Steeltrac 18

Which one should you buy?

Both of these are sold into the same segment, so the choice comes down to a handful of real differences rather than one being better than the other outright.

Price

The Powertrac Steeltrac 18 is roughly ₹1.3 lakh cheaper ex-showroom — about 35% less than the Sonalika GT 20. On road that gap widens slightly, because RTO tax and insurance are calculated on the higher figure. Whether the Sonalika GT 20 earns that back depends entirely on the points below; if it does not, the cheaper machine is the better buy.

PTO power — the number that matters

Engine horsepower is the headline; PTO horsepower is what actually turns a rotavator or a thresher. Here the Powertrac Steeltrac 18 delivers 2.1 HP more at the PTO (Sonalika GT 20: 10.3 HP, Powertrac Steeltrac 18: 12.4 HP). That is roughly the difference between comfortably running a similarly sized rotavator and working the engine hard to do it.

Lifting capacity

The Sonalika GT 20 lifts 100 kg more (Sonalika GT 20: 650 Kg, Powertrac Steeltrac 18: 550 KG). This decides which mounted implements the tractor can actually carry, and it is where cheaper models usually cut corners. Check it against the heaviest implement you own — loaded weight, not the dry weight in the brochure.

2WD or 4WD

This is the biggest practical split between the two. The Sonalika GT 20 is four-wheel drive; the Powertrac Steeltrac 18 is two-wheel drive. If you puddle paddy every season or work on slopes, 4WD is close to essential and worth the extra cost and fuel. On level, dry land doing mostly haulage, it is money spent for little return — take the Powertrac Steeltrac 18.

Engine

The Sonalika GT 20 runs 3 cylinders against the Powertrac Steeltrac 18's 1. More cylinders generally means smoother running and less vibration over a long day, at the cost of a little more fuel and slightly dearer servicing. Fewer cylinders is simpler to maintain, which matters if your nearest workshop is far.

Gearbox

Sonalika GT 20: 6 Forward +2 Reverse. Powertrac Steeltrac 18: 8 Forward + 2 Reverse. Count the low-range speeds rather than the total — puddling and rotavating need slow ground speed at working engine revs, and a box with too few low gears forces a compromise between the two.

Weight

The Powertrac Steeltrac 18 is about 121 kg heavier. Weight is an advantage when braking a loaded trolley or pulling hard in draft work, and a disadvantage in wet fields and on soft ground where the Sonalika GT 20 will compact less and sink less.

The short answer

Taken together the Powertrac Steeltrac 18 leads on more of the dimensions that affect day-to-day work. It is the safer pick unless the Sonalika GT 20 is meaningfully cheaper for you after the dealer quote.

• Wet fields, puddling or slopes: the Sonalika GT 20, because it is four-wheel drive. On dry level land the Powertrac Steeltrac 18 does the same work for less.
• Wide rotavator, thresher or heavy PTO work: the Powertrac Steeltrac 18 — it has the PTO horsepower to hold speed under load.
• Heavy mounted implements: the Sonalika GT 20, which has the hydraulics to carry them.
• Loaded trolley and haulage: the Powertrac Steeltrac 18 — the extra weight helps it brake and hold a load on a gradient.
• Tightest budget, or if none of the above apply to you: the Powertrac Steeltrac 18. Paying for capability you never use is the most common and most expensive mistake at this size.

Before you decide

• Prices here are ex-showroom. Add roughly 7–10% for RTO registration and insurance, and get the on-road figure in writing from the dealer, itemised.
• Visit more than one dealer for each brand. Exchange value and finance terms vary between showrooms by more than the price gap between these two machines.
• Ask how far the nearest workshop is for each brand. A tractor that is down for a week in season costs more than the difference between these two.
• Drive both with an implement attached, not empty. An unloaded tractor tells you very little.
