Overview

About this machine

The FSI B21 stump cutter is the popular choice when it comes to walk-behind stump grinders in the UK.

With a pivoting cutter arm, individual wheel brakes, vibration-damped operator handle, and the patented hill-hold system, this stump cutter makes working easy and efficient for operators of all skill levels.

With the FSI B21 stump cutter, operators have a reliable, sturdy, and easy-to-use solution to remove any stump.

No daily maintenance

The closed bearing for the cutter wheel is pre-greased from factory for more than 1000 hours of normal operation, eliminating the risk of under- or overgreasing and making daily maintenance a thing of the past.

Hill-hold system

This patented brake system blocks any forward motion of the wheels, allowing the operator to pull the stump cutter backward on ramps, up steps, or in uneven terrain with little effort and increased safety.

Operator-friendly

The vibration-damped and height-adjustable handle combined with the pivot-point design makes it less strenuous for the operator to sweep the cutter arm from side to side.

Simple tensioning

The single-sided mounting of the cutting disc makes tensioning the banded V-belt simple, as no parallelism is to be maintained.

Safe transport

With multiple, easy-accessible lashing and lifting points you can quickly fasten this stump cutter for transport and arrive safely to the next jobsite.

Financing the FSI B21 with Buckingham Leasing

The FSI B21 is a engine stump grinder from FSI, the Danish manufacturer whose machines are widely used by UK tree and grounds professionals. It suits arborists, tree surgeons, landscapers, grounds maintenance contractors and local authority teams who need a self-contained machine that can be driven or walked straight to the stump.

Headline figures from the manufacturer: engine size 10.5 kW / 14 hp / 8.2 kW / 11.1 hp, 8.2 kW/11.1 hp, sweep 90 cm, below ground level 25 cm, weight 130 kg / 135 kg. Always check the latest data sheet with your dealer before ordering.

Ways to fund it

  • Hire purchase: spread the cost over a fixed term and own the FSI B21 at the end.
  • Finance lease: keep capital free and pay for the machine while it earns, with options at the end of the term.
  • Seasonal or stepped payments: shape repayments around busier winter and spring felling periods where lenders allow.
  • Refinance: release cash tied up in machinery you already own to help fund a new grinder.

Things to think about before you buy

  • Access widths and ground conditions on your typical jobs, as they decide between wheeled, tracked, pedestrian or attachment models.
  • Tooth and wear part costs, servicing intervals and dealer support near you.
  • How the grinder will be transported, including trailer weight limits and towing entitlement.
  • Whether new or used stock gives better value for your workload.

We arrange finance for new and used FSI stump grinders from £5,000 upwards, for sole traders, partnerships and limited companies across the UK. Send us the dealer quote and we will come back with clear options in plain English.
