7.5 HP Petrol Wood Chipper for Garden Waste – 150A Chipper Specs and Buying Guide
Turn prunings and small branches into mulch and firewood kindling – what to check before buying a 6 cm garden chipper
A petrol wood chipper is a self-powered machine that pulls branches into a cutting disc and discharges wood chips. The 150A is a mobile, towable unit rated for branches up to 6 cm in diameter — the practical limit for most garden, orchard and small-farm material.
The 150A wood chipper uses a 150 mm double-edged blade pair with a stationary counter knife, powered by a 7.5 HP Rato petrol engine as standard. It processes roughly 0.8–1 ton of material per hour and is light enough (90 kg net) for two people to move and one vehicle to tow between sites.
The 6 cm diameter limit covers the majority of everyday woody waste:
Tree prunings and hedge trimmings – the main winter and spring workload for most buyers
Orchard and vineyard canes – thin, dense material that clogs weak machines, handled by the twin-blade disc
Storm and windfall branches – up to the 6 cm rated maximum
Small construction offcuts – clean timber and pallet offcuts below the diameter limit
Output chips suit mulch, compost acceleration, and kindling for fireplaces and outdoor boilers. The 2800 r/min disc speed keeps throughput steady without the need for a second feed roller on a machine in this class.
Homeowners with large gardens – clearing annual pruning waste instead of paying green-waste collection
Small farms and orchards – converting prunings into mulch on site
Property and landscape contractors – a budget-class chipper for light daily duty
Firewood households – producing kindling and clean mulch from offcuts
Buyers who regularly chip material above 6 cm should compare the 300B model in the same line, which handles 12 cm branches at 1–2 tons per hour.
The specification, summarized against what each figure means for the buyer:
The standard fit is the 7.5 HP Rato petrol engine with recoil start. Three alternatives are commonly offered:
Yahu / Loncin petrol 7.5 HP – interchangeable equivalents where buyers prefer a second brand for their local spares network
Yanmar-series diesel 8 HP with electric start – for operators who prefer diesel economy and push-button starting; diesel models add weight (120 kg gross) and are offered from five units per order
4.8 kW electric motor version – for indoor or covered use where exhaust is not acceptable; check single-phase supply compatibility
Choosing between them is a question of local fuel preference and spare-parts access more than performance — all options run the same 2800 r/min disc. Confirm the starting type (recoil vs electric) and the fuel standard for your market before ordering.
Rated up to 6 cm diameter. Feed material at a steady angle and trim side branches for the cleanest cut.
Yes, but wet material produces wet chips that compact more slowly in compost. Dry material chips faster and is easier on the blades.
One person can feed most material, but a helper is useful for long or heavy branches. The machine itself is towable and light enough for two people to position.
Check blade sharpness regularly, keep the counter knife gapped correctly, and change engine oil per the manual. The double-edged blade can be rotated before sharpening.
For most gardens and small farms, yes. If you regularly clear storm damage or wood above 6 cm, compare the 12 cm 300B model before deciding.
A 6 cm wood chipper is a practical way to turn pruning waste into mulch, compost and kindling without paying for green-waste collection. The 150A pairs a 7.5 HP Rato petrol engine, a 150 mm twin-blade disc and a 0.8–1 t/h output in a 90 kg, towable frame sized for garden work. Confirm the engine option, start type and market certification with your supplier — and ask for the full specification sheet and pricing from our companybefore you order.
