Battery combi systems

What is a cordless combi system?

A cordless combi system is a single motor unit with a shaft to which various working attachments are connected. Today it's a grass trimmer, tomorrow it's a pole saw or a hedge trimmer. A combi system eliminates the need to store multiple tools with separate motors, batteries, and chargers.

What is a cordless combi system used for?

A combi system is used to cut grass along fences, shape hedges, trim lawn edges, and cut branches above head height. For regular mowing of large areas, cordless trimmers with a separate housing may be more convenient. In a yard where each task is performed several times a season, interchangeable attachments are usually sufficient.

Cordless combi system specifications

Before choosing, check specific parameters:

• battery voltage — 18–20 V for grass and young shoots, 36–40 V for dense vegetation;
• battery capacity — 4–5 Ah provides more time between charges;
• clutch type — the attachment must be fixed without play;
• motor unit weight — with a long shaft, a heavy body quickly tires the hands;
• shaft length — affects the working radius and balance;
• speed adjustment — different speeds are required for line, blade, and saw attachments.

How a cordless combi system works

The electric motor transmits rotation through a shaft inside the pole. After installing the trimmer head, the combi system cuts grass; with a pole saw attachment, it moves the chain; and with a hedge trimmer attachment, it moves the blade. Before changing attachments, the battery is removed, and the clutch is cleaned of grass and dust.

Advantages of using a cordless combi system

A cordless combi system takes up less space in the garage and runs on a single battery series. There's no need to buy three motor units for seasonal tasks that take several hours. A single base is easier to transport to the dacha, maintain, and prepare for storage.

What attachments does a cordless combi system support?

The motor unit can connect a trimmer spool, grass blade, cultivator, path brush, pole saw, and cordless hedge trimmer. The set depends on the series and manufacturer. Attachments with the same shaft diameter are not always compatible: the shaft shape, lock, and permissible load on the drive differ.

Recommendations for choosing a cordless combi system

For lawns and low hedges, trimmer and hedge trimmer heads are needed. For old trees, the combi system must support an attachment similar in principle to cordless pole saws, and a telescopic extension. If the attachment has to be held overhead, the weight is calculated together with the battery and the working part.

Where to buy a cordless combi system?

Combi systems should be considered along with a list of compatible attachments, not just by the price of the motor unit. If the required head is not available for a specific series, it will not be possible to purchase it later. The motor unit, battery, charger, and attachments for grass, bushes, and branches can be assembled at Flash Army within a single system. In such a kit, each working part fits the drive, and the battery doesn't sit idle between seasonal tasks.
