Pneumatic bulb planter — garlic, onion, spring onion, potato microtubers (3–8 rows)
The PLNA (Bulb Air Planter) is a pneumatic bulb planter from Broch, designed for planting bulb crops: garlic, onion, spring onion and potato microtubers. The heart of the machine is the combination of two systems: a pneumatic disc precisely picks up (singulates) a single clove or bulb, and a mechanical separation system places it in the row; according to the manufacturer it is “the best combination for planting bulb crops”, especially large fractions. The design maintains precision at a working speed of 3–5 km/h, and planting depth is adjustable from a few millimetres up to 20 cm. The range includes models PLNA-3…PLNA-8 (3–8 rows); each planter is configured to the layout and planting conditions of the specific farm. Manufacturer based in Arganda del Rey, near Madrid.
Two systems in one
The pneumatic disc picks up a single gap (singulation), and the mechanical system separates it and places it in the row. Large fractions require exactly this combination — pneumatics alone or mechanics alone do not give this repeatability.
Precision at speed
The recommended working speed is 3–5 km/h; for higher speeds the manufacturer offers a dual-disc system. The radial speed of the separation elements is matched so that the spacing in the row does not “spread out” at higher speed.
Depth from mm to 20 cm
The furrow opener connected to the rear wheel via parallelogram linkage and adjustable drive wheels give smooth depth control — from a few millimetres up to 20 cm, depending on crop and conditions.
Gentle pick-up from the hopper
The moving, vibrating lower part of the hopper (floating motion) portions material for pneumatic pick-up and is adjusted to the clove/gap size — fewer damaged pieces, steady flow.

Garlic, onion, spring onion and potato microtubers. It is a pneumatic onion planter: one machine type for several crops, configured to the planting pattern.
The PLMA meters cloves with a disc fitted with spoon grippers (mechanically). The PLNA combines pneumatic singulation (disc) with mechanical separation. According to the manufacturer, it is the better solution for planting bulb crops, especially large fractions, and for working at speed.
The recommended working speed is 3–5 km/h; for higher speeds the manufacturer offers a twin-disc system and requires optimal soil and working conditions.
Adjustable from a few millimetres up to 20 cm, using a frame with a rear gauge wheel (parallelogram) and adjustable drive wheels.
The PLNA-3…PLNA-8 family covers 3–8 rows; power requirement rises from 70 hp (PLNA-3) to 120 hp (PLNA-8), and output ranges from 2.5 to 6.5 ha per 8 h of work.
