Swing-arm Stump Grinder

Robust and efficient hydraulic attachments

Swing-arm Stump Grinder
SG1SW

The SG1SW is a high-performance stump grinding attachment, specifically developed for use with loader-type carrier machines.

The cutting head is mounted on a swing-arm, mimicking the action of a conventional dedicated stump grinder, resulting in a unit that is both easy to use and extremely efficient, due to the smooth cutting action that the swing-arm provides. An offset arm offers unparalleled operator visibility, while the drive system has been optimised to put all available hydraulic power to good use, ensuring rapid removal of even the most stubborn stumps.

The build quality is second-to-none, with all components carefully designed to withstand the robust treatment that is often required to get the job done.

Product Features

Swing Arm Stump Grinder Key Feature 1

The swing-arm is controlled by a 12V electric valve, removing the need for an additional auxiliary circuit. The ram speed can also be finely adjusted, allowing the stump grinder to be optimised for many different carrier machines

Swing Arm Stump Grinder Key Feature 2

The practically unbreakable tempered steel shaft runs in two massive taper-roller bearings, offering all of the efficiency gains of a direct-drive system (no power lost to belts or gearboxes), while protecting the motor from high axial and radial loads

Swing Arm Stump Grinder Key Feature 3

The cutting wheel turns at a relatively low speed but with very high torque, which ensures that power goes into the stump rather being lost to aerodynamic drag

Swing Arm Stump Grinder Key Feature 4

The replaceable, self-sharpening tungsten carbide teeth have multiple cutting edges, reducing wearing part costs, and can easily be rotated or changed without the need to brace the cutting wheel

Swing Arm Stump Grinder Key Feature 5

The stump grinder has comprehensive rubber guarding, protecting the operator from flying debris

Swing Arm Stump Grinder Key Feature 6

The cutting wheel is designed to retain momentum, evening out load peaks, and permitting smooth, even cuts

Swing Arm Stump Grinder Key Feature 7

The cutting head is mounted on an offset swing-arm and is operated by a dedicated ram, ensuring a smooth, efficient cutting action and class-leading visibility

Review of the Klou Swing-arm Stump Grinder

"This stump grinder is a little beauty!

It has truly outperformed expectations when used with our mini skid-steer, all but removing the need for a pedestrian stump grinder. The smooth cutting action and impressive amount of torque allow it to remove stumps very quickly, while the offset mounting of the arm ensures good visibility, making it very easy to operate. It’s great from an H&S point of view as well – being hydraulically operated, there’s no risk of anyone straining their back while using it. Basically, I can now convert my skid-steer into a high-performance stump grinding unit at will!"

Testimonials

"The Klou stump grinder attachment is an excellent bit of kit, with its reach and ability to get to places another machine can’t. Don’t expect the performance of a dedicated stump grinder, but why pay for and then maintain an extra engine and transmission when you’ve already got your own excavator? Sitting comfortably in a quiet and safe digger cab, you can still get the job done very quickly, as long as you are gentle on the controls. Also, the Klou attachment is nice and small, and therefore very easy to transport – not like bringing an additional machine to site

The grinder is very well made, and the customer service that I have received from Klou is excellent."

“I have noted below some of the benefits we have noticed from owning a Klou Cone Splitter:

Faster, easier and safer firewood processing

The option to split down larger sections of timber for the chipper, saving on extra vehicle trips and space in our yard for low-value timber

The larger timber arisings from tree work can be an extra burden to remove. Customers are often happy to keep the smaller timber that won’t go through the chipper but the oversized timber is too large for them to manage. Having the ability to offer all of the timber to be left in a manageable size saves cost for us and replaces that with a valuable chargeable service to the customer.”

"This post driver really works!

Over the years we have used conventional hammer post pounders which are heavy on the hitch and don’t drive stakes into the ground a fraction as well as the Klou post driver. The KPD1 vibrates posts deep into the ground at any angle you want. Klou offers a full tailored service of different post cup sizes and hitch attachments so you can use it on any size digger. I won’t be using anything else."
