Duo range - combination wood chipper and green waste shredders
The Landforce Duo 235 combination wood chipper and green waste shredder in action, making short work of whatever is thrown at it!
Enough power for you?
The Hardmet Landforce Duo combination chipper shredders are priced to compete with dedicated single use machines.
If you're an arboriculturalist, tree surgeon, contractor or hire company, a Duo chipper/shredder is the machine for you, offering flexibility where it's needed.
These are very rugged dual-purpose machines that deal with everything from large branches to light brush. With the shredder, brash and waste materials are processed to form materials for mulch, compost or recycling for on-site use. Chippings from the chipper can be used as mulch or to reduce material volume for off-site disposal.
The Hardmet Landforce Duo 235 machine - British built and a bit of a brute, with a 61hp Deutz diesel.
It almost has too much power - not a bad fault!
This is a combined chipper and shredder designed to cope with everything you are likely to meet on site.
It's a solidly-built machine and will last for years.

You can feed the chipper and the shredder at the same time for maximum time efficiency. Push the sweepings and other detritus through the shredder to get your crews away as effectively as possible at the end of the day.
The shredder element of the Duo machines is a helical flight design, combining low power consumption with aggressive action. Designed for lower noise operation, both the chipper and shredder lacerate the incoming material to reduce volume and promote rapid decomposition. The flywheel chipper on all models is fed via hydraulic powered rollers that automatically cut the feed to the chipper when the engine speed drops below a preset limit, reducing the chance of blockages.
