Just got your RFQ in, and I can tell you we've moved a lot of these over the years, so I can walk you through what matters. The 31cc 4-stroke engine is basically what sets it apart from the 2-stroke noise makers—it's a G139F-1 model, so 0.8kw at 6500rpm, and yes, it runs on straight unleaded gasoline, no mixing oil. One thing buyers don't always ask about is diaphragm carburetor; it keeps the fuel feed steady even when you're tilting the thing sideways to get under a bush.

You'll want to know about the vibration level because that's a real pain point for operators—it's under 2.5 meters per second squared, which is better than most in this class. The shaft comes in either 26mm or 28mm diameter, 1650mm long, and honestly, the 28mm feels more solid for heavy brush, but the 26mm is fine for regular grass. Also, the width goes up to 500mm, so you can clear a decent swath without making multiple passes.

Fuel consumption is about 0.5 liters per hour at full load, and the tank holds 0.8L, so you're looking at around an hour and a half of heavy work before refueling. Oil tank is 0.08L, and it uses splash lubrication—nothing fancy, but it works fine as long as you check the level. 4-strokes are generally quieter than 2-strokes, so noise is under 95 decibels, which makes a difference if you're working near houses.

One thing it's not great for is thick woody shrubs over about a centimeter in diameter—it'll struggle on stuff like that, and you're better off with a blade upgrade or a heavier unit. We usually have stock on these, but lead times can shift during peak season, so factor in about 20 working days or so for a standard order. Packaing is straightforward: a single box at 35 by 31 by 23.5 centimeters, weight about 6.8 kilos without the head.

A common question is about the recoil starter—it's a standerd pull-start, nothing fancy, but we've had very few complaints on that end. The CDI ignition is pretty reliabel, and the whole thing carries a 12-month warranty, though most issues come form people forgetting to put oil in the crankcase. 2-stroke users tend to skip that step, so it's worth mentioning.

You'll want to specify attachments seprately—the unit ships without one, so just let us know if you need a blade or a head. 10mg or 10mm? Actually, width is 500mm max, and the shaft diameter is your choice between the two options we stock. Anyway, if you're good with those specs, our company can get a quote together with MOQ details and lead time.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for the G139F-1 brush cutter?

Our standard MOQ is 50 units per model, but we can discuss smaller trial orders if you're just getting started.

What certifications or quality documents do you provide with this 31cc brush cutter?

We supply CE, EPA, and EU emission certificates, along with a detailed test report for each batch. The 12-month warranty covers manufacturing defects.

Can the cutting width be adjusted from the standard 500mm?

No, the 500mm cutting width is fixed for this model, as it's based on the blade or head design. It's optimized for clearing grass, weeds, and shrubs up to 1cm thick.

How is the brush cutter packaged for export, and what's the lead time?

Each unit comes in a carton box sized 35×31×23.5cm, with foam inserts for protection. Lead time is typically 20–30 days after order confirmation, depending on quantity.

What type of oil should I use for the 4-stroke engine and how often do I need to change it?

Use a high-quality SAE 10W-30 or 20W-50 4-stroke oil. The oil tank holds 0.08L, and we recommend changing it every 25–30 hours of use for best performance.
