The Cheapest Way to Handle Prunings Is Not a Bigger Truck: A Towable Branch Chipper That Follows the Trees — Weiwei Machinery
Orchard and plantation owners usually start by asking for a bigger trailer. The problem is not the trailer. Fresh prunings and branchwood bulk at something like 40 to 60 kg per cubic metre, so a load that looks full weighs very little, and every kilometre is paid on volume. The material is also lifted and loaded by hand twice before it reaches any chipper.
The fix is to move the machine instead of the wood. The WBC-1000 is built on a towable chassis with a drawbar, two road wheels and a stand, and it carries its own 192F diesel engine, so it does not need a tractor PTO and it does not need three-phase power at the row end. Weight is 210 kg in the towable version, which puts it behind a pickup, a small tractor or a three-wheeler. One person can unhook it, start it and work a block of trees before moving on.
The blade length sets the job. WBC-600 runs a 15 cm blade and takes 400 to 600 kg per hour. WBC-1000 runs a 30 cm blade at 800 to 1000 kg per hour, which is what allows orchard prunings, coffee and oil palm fronds and roadside cuttings to go in without being cut down to length first. Output is quoted on fresh material, not on dry wood, because that is what comes off the tree.
Discharge is aimed, not dropped. The curved outlet pipe throws the chips in one direction, so the machine can be positioned to blow into a trailer, into a row between trees, or onto a tarpaulin. Chips blown into a windrow break down into mulch where they fall; chips blown into a trailer leave the site as a product. The same machine serves both, and the operator chooses where to park it.
Three power options sit on the same frame. The electric version uses a 7.5 kW motor for a yard with power and a fixed work area. The gasoline version uses a 190F engine for buyers who want the lightest starting procedure. The diesel versions use a 192F engine, and the towable diesel adds the road chassis for work that moves every day. Same rotor, same blade, same 1300 x 740 x 1400 mm body; what changes is where the machine can go.
Where the chips end up decides whether the purchase pays. Mulch returned to the rows holds moisture and suppresses weeds. Chips sold to a nursery, a biomass buyer or a compost yard turn the pruning cost into a small income, but only if the chip size is consistent, which is why the blade and the screen behind it matter more than the engine size.
