If you are an arb professional then tree stump removal will be a familiar request from your clients.


The stumps can often be in back gardens - with tough access, side alleys and other obstacles to negotiate. 


Without the right equipment you either subcontract the work, or hire a stump grinder - and the average hire rate for a basic stump grinder isn't cheap - up to £120 per day for a small machine. When you add your time and fuel just to collect the kit, then any profit can soon disappear!


It's no surprise so many arborists refuse to offer a stump removal service at all.


But the business is there - are you missing out?


If only you could utilize an existing tool you already take to site (i.e your chainsaw) and turn it into an access all areas stump grinder!


Well now you can.


The ST-661 & ST-880 are lightweight, high performance tree stump grinders that can quickly attach to the Stihl MS 661 or MS 880 chainsaw. 


Manufactured in the UK from tough lightweight materials - the attachments are the perfect solution for arb professionals who want to offer a simple, access all areas, professional stump removal service, but without excessive outlay.

The attachments are compact - The ST-661 be carried at under 25kg. Simply take to site with the rest of your tools and you're ready to offer a stump removal service in your own time, whenever you want!


No more lost profits on subcontracting or hire. You now have an additional service you'll WANT to offer.


Whether the stump is in a back garden, up a bank, down steps, through a house or up against a wall, you now have the kit to look professional and finish the job. 


With a light footprint, these stump grinder attachments are perfect for precision removal in delicate areas such as flowerbeds or prize lawns. 


The ST-661 or ST-880 are the perfect access all areas tree stump removal tool for both the smaller firm, and the stump grinding professional looking to compliment their fleet.




- I get that it's portable & compact, but does that mean it takes longer to remove a stump?


A. On average, the ST661 will handle a 12 inch diameter stump in under 15 mins. We aren't going to promise it'll be this quick everytime, it may take up to 30 mins depending on timber & root system, and how sharp you keep the teeth! But frankly, we don't think this is slow - not when some companies charge over £100 for completing that kind of stump removal in the UK. 


It will take a lot longer and be a lot less profitable if you have to leave site, hire a rental machine, then return to finish the job just to keep your client happy. Remember, you are not buying a 50 horsepower commercial stump grinder here - grinding time is almost irrelevant. You are buying an access all areas tool, and one so portable you can transport in nearly any vehicle. You can now efficiently remove those tough access stumps that your competition can't reach.


- Are the attachments expensive?


A. If you buy an attachment and don't use it, then yes it will be expensive. For many arborists the demand for stump removal is inevitable. You won't have any option but put the attachment to work. *Many companies will charge £100 minimum for the smallest stump, and when it takes under 30 mins to remove these with a simple tool attached to your chainsaw, you'll soon realise how many opportunities you've been missing.


- So is it affordable?


A. You could already be hiring a low spec, two wheeled stump grinder for up to £120 a day from a rental company. If you already have the chainsaw, then some finance options for the ST661 could be as little as £13+VAT per week** - When you do the math, that's only a few minutes of stump grinding!
