Knife or hammer wear
Flails never wear evenly. A few grams of difference at the rotor radius is enough to shake the whole machine.
Balanset-1A
Mulcher Vibrating? Balance the Rotor in the Field in 40 Minutes
Worn knives, a lost hammer, buildup or repair welding — whatever caused the imbalance, Balanset-1A finds it and fixes it right on the machine. No disassembly, no service callout.
No Disassembly
Balance the rotor right on the mulcher, at working RPM
Diagnose First
The built-in vibration analyzer tells imbalance from bearing wear

Any of these is enough
Why Mulchers Get Out of Balance
Knife replacement
Even a brand-new knife set is never perfectly matched in weight — balance after every change.
Lost or broken flails
A sheared bolt or a flail lost in the field throws the rotor out instantly.
Material buildup
Resin, soil and plant matter stick to the rotor unevenly and shift its mass.
Repair welding
Every weld seam adds uneven mass. A repaired rotor must be rebalanced.
Not sure it is imbalance?
Balanset-1A is also a vibration analyzer: the spectrum shows whether vibration comes from imbalance or a failing bearing — before you spend a cent on parts.
How It Works
How Field Balancing Works
Two-plane dynamic balancing directly on the machine, at PTO working speed. A typical mulcher takes about 40 minutes.
-
01
Mount the sensors
Two vibration sensors go on the rotor bearing housings with magnetic mounts. The laser tachometer points at a strip of reflective tape on the shaft.
-
02
Measure the initial vibration
Run the rotor at working RPM. The software records vibration level and phase in both planes — this is your baseline.
-
03
Trial weight run
Attach a known trial weight, measure again. The software computes the exact correction mass and angle for each plane.
-
04
Correct and verify
Fix the correction weights, run once more. Vibration drops to norm — the software shows the residual imbalance in numbers.

A Real Job: Mulcher Balancing in a Farm Workshop

Stop the damage: Balanset-1A
Eliminate imbalance yourself in an hour — without calling service and costly downtime. The device pays for itself after the first prevented accident.
The Economics
Why Owners Balance Mulchers Themselves
Pays for itself in 1–2 jobs
A service callout costs €500–1,500 every time. Balanset-1A is €1,975 once — and you keep it.
No downtime in season
No waiting days for a technician when the mulcher must be in the field tomorrow. Balance it the same day.
Bearings and welds last longer
Vibration destroys bearings, cracks welds and loosens bolts. Balancing removes the root cause, not the symptoms.
Engineer support at all stages
Consultation before purchase, guided first balancing, and help with your real measurement data afterwards. You are never alone with the device.
One device for all rotors
Mulcher today, chipper, mower, fan or cardan shaft tomorrow — any rotor from 100 to 100,000 rpm.
Learn in a day
The software guides you run by run. Most users complete their first real balancing on day one.
Service Callout vs Your Own Balanset-1A
| Service callout | Balanset-1A | |
|---|---|---|
| Cost | €500–1,500 per visit, every time | €1,975 once — pays off in 1–2 jobs |
| Waiting time | Days to weeks in high season | Balance the same day, yourself |
| Where | Often requires transport to a workshop | In the field, on the machine |
| After every knife change | A new invoice each time | Included — it is your device |
| Vibration diagnostics | Extra service, extra cost | Built-in vibration analyzer |

Mulcher Balancing — Common Questions
Balanset-1A shows the vibration spectrum before you balance. Imbalance produces a dominant peak at 1× rotation frequency; bearing defects look different. You diagnose first, then decide — no guessing and no parts bought on suspicion.
Yes — even a new knife set is never perfectly weight-matched. It takes about 40 minutes with your own device, so most owners simply make it part of the knife-change routine.
Yes. Balanset-1A balances any rigid rotor from 100 to 100,000 rpm — flail mulchers, forestry mulchers, flail mowers, chippers, fans. The mount is magnetic; no modifications to the machine.
No. The software guides you step by step: measure, add a trial weight, and it computes the exact correction mass and angle. Most users learn it in one day.
Yes. Balancing compensates the current mass distribution of the rotor, whatever its cause. If wear is extreme, replace the worst flails first, then balance the rest of the way.
You will not be left alone: our engineers assist before the purchase, during your first balancing session, and afterwards — with your actual measurement data. Send the readings and you get concrete instructions back.
The measurement unit, two vibration sensors, a laser tachometer with reflective tape, magnetic mounts, electronic scales, software, and a hard carrying case — everything needed to balance in the field. €1,975, one-time.
