3TG-4A 4×4 Agriculture Tiller 6.3kW Shaft Drive Double Shaft
The 3TG-4A is a 6.3kW walk behind agriculture tiller for farms and contractors working ground that stalls a belt driven machine. Power reaches the working shafts through shaft transmission rather than a belt, so torque holds in heavy or stony soil where a belt would slip and glaze. The double shaft wheel type chassis runs a rotary knife to 800mm, a slotting knife to 300mm and a tilling width of 350mm, covering primary cultivation, furrow cutting and inter-row work with one power unit. The armrest adjusts both up and down and left and right, letting the operator stand out of the worked strip on a long run. SONJUN produces it to order with OEM branding and ships from Ningbo or Shanghai.
- Shaft transmission instead of a belt keeps torque up in heavy soil where a belt slips and burns
- 6.3kW rated power gives headroom when the rotary knife loads up in wet or root bound ground
- 800mm rotary knife width finishes a bed in one pass on open ground
- 300mm slotting knife cuts drainage and irrigation furrows without a separate machine
- Armrest swings left and right as well as up and down so the operator walks clear of freshly turned soil
- No drive belt to replace each season, which removes the most common field consumable

Application Scenarios
- Primary cultivation of vegetable and field crop beds before planting
- Heavy, stony or root bound ground that stalls a belt driven cultivator
- Cutting drainage and irrigation furrows with the 300mm slotting knife
- Inter-row tilling at 350mm working width in planted crops
- Contract cultivation crews running long days across multiple smallholdings
Who It Is For
- Importers and distributors stocking mid power walk behind cultivation equipment
- Agricultural machinery dealers serving arable and horticultural customers
- Farms and cooperatives cultivating heavier soils
- Contract cultivation and land preparation crews
- Machinery rental fleets needing a machine that survives untrained operators
Problems It Solves
- Belt drives slip and glaze when a cultivator loads up; shaft transmission passes the torque through
- A 4.0kW machine bogs down in heavy soil and forces shallow repeat passes
- Replacing drive belts every season is a running cost and a spare part the buyer has to stock
- Separate ditching equipment ties up capital that a smallholding cannot justify
- Fixed handlebars force the operator to walk in the tilled strip and lose their footing over a long run
Technical Features
- Double shaft, wheel type structural form
- Shaft transmission engine output rather than belt drive
- Rated power 6.3kW at 3600r/min
- Main clutch normally open
- Rotary knife working width 800mm
- Slotting knife working width 300mm
- Tiller working width 350mm

- Rotary knife, slotting knife or tiller working device supplied to suit the market
- Manual and packaging artwork in the destination market language
How It Compares
Against Belt drive garden tiller
A belt drive is cheap to service but slips under sustained load. This machine uses shaft transmission, which holds torque in heavy ground and removes the seasonal belt replacement.
Against 4.0kW mini tiller
The smaller machine suits tunnels and narrow rows. At 6.3kW with an 800mm rotary knife, this one is sized for open field primary cultivation.
Against Mini farm tractor
A ride on tractor covers more ground but needs headland room and a larger budget. This walk behind unit works confined plots and orchard rows at a fraction of the capital cost.
Use Guide
- Check engine oil and transmission oil level before the first start of the working day
- Fit the working device that matches the job: rotary knife for cultivation, slotting knife for furrows
- Set armrest height and side swing so the operator walks beside the worked strip
- Start shallow on dry or compacted ground and deepen over a second pass rather than forcing the knives
- Stop the engine before changing a working device or clearing wrapped residue from the shaft
- Wash soil off the shafts and knives after use and store the machine dry
4WD Agriculture tiller Buyer Questions
What is the minimum order quantity?
One 20ft container. Sample orders are accepted and a single piece sample order is acceptable.
How long is the lead time?
25 to 35 days for one 40HQ container. A sample order ships in 1 to 7 days.
Why choose shaft transmission over a belt drive?
Shaft transmission passes torque through without slipping when the knives load up in heavy soil, and there is no drive belt for the end user to replace each season.
Can we sell it under our own brand?
Yes. OEM and ODM production is available, including buyer branding, colour scheme, manual and packaging artwork.
Is the machine CE certified?
No CE certificate is claimed for this model. Tell us your destination market and we will confirm what can be arranged before you place the order.
How do we buy spare parts later?
Within warranty, parts needed because of a quality problem are replaced free of charge. Outside warranty, spare parts are sold at cost price.
What payment terms and port of shipment do you use?
Western Union, PayPal or T/T depending on order quantity, shipping from Ningbo or Shanghai.
