SAT-R201 · 5 HP Diesel / Petrol

Differential Power Reaper for small, irregular fields.

The same 5 HP cutter bar as our best-selling reaper — now with a differential drive and lock. Spin through headland turns in seconds and keep grip in wet paddy, loose sand and sloping ground.

Overview

Built for fields where turning eats the day.

01/ OVERVIEW

Small plots make their own rules. When land is sliced into strips by bunds, canal lines or family partitions, a reaper spends a big share of every hour turning at the headland — and so does the operator's back. The SAT-R201 was designed for exactly that reality. It carries the proven cutter bar and 5 HP engine options of our self-propelled power reaper, and adds a differential axle that turns every headland into a quick pivot instead of a tug-of-war.

We recommend it for plots under two acres, paddy land that stays wet at harvest, sandy soils and any farm shaped more like a puzzle than a rectangle. If your fields are large, open and rectangular, the standard model may serve you at lower cost — our comparison guide, Differential vs Standard Reaper, walks through the honest math.

Prefer to ride instead of walk? Fit the SAT-S701 seating attachment and steer through the harvest from a seat. Every unit ships factory-direct from Ahmedabad and is serviced through dealers across 9+ states.

Differential gearbox of the SAT-R201 power reaper — allows the outer wheel to rotate faster in turns
The Mechanism

How the differential gearbox works

Power from the 5 HP engine reaches the axle through a differential — the same principle a car uses. Through a turn, the outside wheel has more ground to cover, so the gearbox lets it spin faster while the inside wheel slows down. The machine wheels itself around the headland on its own power instead of being dragged through by force.

Hit a wet patch or a loose bund and one wheel starts to spin? Pull the lock lever. The differential lock couples both wheels into a single driven axle, and they push together until you are back on firm ground.

True differential drive

The outer wheel speeds up through every turn, so the machine pivots cleanly at the headland instead of skidding and gouging the bund.

Lever-engaged diff lock

Couple both wheels on demand for wet paddy, loose sand or slopes — traction exactly when a single wheel would spin.

Two proven 5 HP engines

Greaves diesel with 3-belt drive for long custom-hire days, or Honda GX200 petrol with 2-belt drive for lighter own-farm duty.

4 cm low cutting

Cuts close to the ground so nearly the full stalk comes home — more straw for bhusa, kutti and mandi sale, less residue to burn.

Frugal on fuel

Runs on 700–1000 ml per hour depending on the engine — a full tank comfortably covers a long harvesting session.

Field-hardy build

Mild-steel body, TVS LM45 agricultural tyres and simple clutch-lever controls that any operator masters in a day.

Quick Answers

SAT-R201 questions, answered

What does the differential actually change in daily harvesting?
On a standard reaper, both wheels are driven at one fixed speed, so every headland turn needs muscle. The SAT-R201's differential lets the outer wheel rotate faster than the inner one through a turn, so the machine pivots on its own power. On small or bunded plots — where turns can eat a third of the working day — that difference shows up directly in acres finished and operator fatigue.
When should I engage the differential lock?
Use the lock whenever one wheel starts losing grip: wet paddy fields, loose or sandy soil, and slopes. Pulling the lever couples both wheels into a single driven axle so they push together. Release it again for normal cutting and turning, where the free differential gives you the smoothest steering.
Diesel or petrol — which SAT-R201 engine should I choose?
The 5 HP Greaves diesel (3-belt drive, 4.5 L tank, 260 kg) is built for continuous, heavy use and handles crop up to 10 ft tall — the choice for custom-hiring. The 5 HP Honda GX200 petrol (2-belt drive, 3.1 L tank, 240 kg) is lighter and easier to start, well suited to own-farm use with crop between 2 and 6 ft. Both cut at 4 cm and cover about an acre an hour.
Which crops can the differential reaper harvest?
Wheat, paddy, barley, oats, soybean, mustard, maize, bajra, jowar, ragi, sunflower and green fodder. The 4 cm minimum cutting height recovers nearly the full stalk, so straw becomes bhusa or kutti instead of field residue.
What is the price of the SAT-R201, and is a subsidy available?
Pricing is factory-direct and shared on request — it varies with the engine option and whether you add the SAT-S701 seating attachment. Reapers qualify for agriculture-department subsidy schemes in several states, and we guide your paperwork based on previous approvals. Call +91 87996 56981 or WhatsApp us for today's quote.
