Viking GB370 shredder and GB370S chipper

Two units or one? The choice is yours. Buy either the GB370 shredder or the GB370S chipper and you can get a conversion kit to swap between the two by changing the blade and feed chutes. It only takes about four minutes to swap and allows a wider range of material to be processed.

The GB370 shredder has a vertical chute with a wide funnel opening. It has a plastic or polymer material on the outside, which gives it the appearance of a domestic machine. But it is only an outer sleeve for soundproofing — the lining inside is metal. The soundproofing works. This machine has a more musical tone even if is a growling sort of noise.
Loading is simple and the GB370 quickly and easily eats its way through soft organic material. It will also tackle slender branches up to 35mm without difficulty. The shreddings are not particularly consistent on size but are fine and should compost down well.
The other machine, the GB370S chipper, has a sloping, soundproofed feed chute that is comfortable to load, while the blade disc’s self-feeding action gently pulls material through the cutters for minimum kick-back.
The toothed blade in the chipper unit has sharp, angled cutter blades and, according to the spec, will tackle branches up to 45mm. We find the machine cuts out with branches measuring 50mm but restarting the 6.5hp engine is effortless. The blades can be reversed, using the tool supplied, to reveal a second sharp set of cutters. After that, they can be re-sharpened with an angle grinder.
Built for mobility, the wide chassis on these well-balanced Viking machines provides good manoeuvrability. The units will pass through a standard-sized gateway. We don’t think you could find a much lighter machine capable of commercial garden duties. The shredder weighs 43kg and the chipper is 44kg, so loading and transporting these machines into the back of a van or pick-up should not be a problem.
