Features:

  • EFFORTLESS START-UP. The decompression valve makes it easier to start your tool. When starting, you can allow some of the compressed mixture to escape from the cylinder by opening the valve. This protects the start-up system and reduces the amount of force required on the starter cord.
  • STIHL ElastoStart™
  • Decompression valve
  • SIMPLIFIED OPERATION. Only one start position is required on the combi lever. Thanks to the stop function, once the machine is turned off the control lever immediately moves back into the operating position. This allows a warm machine to be restarted immediately.
  • STIHL Master Control Lever™ with Stop Function
  • RELIABLE WORK WITH THE BEST PERFORMANCE. With STIHL M-Tronic™, you’ll have the best performance from your work tool from the outset. Fully electronic engine management regulates the ignition timing and fuel metering in all work situations, taking into account external conditions such as temperature, altitude, and fuel quality.
  • STIHL M-Tronic™
  • The HD2 filter is made from polyethylene filter material with up to 70% finer pores than fleece and polyamide filters to trap even very fine dust. In addition, it is oil and water-repellent and thus very easy to clean. The PET-covered filter cartridge with quick-release lock enables the filter to be assembled and disassembled in next to no time, without using tools.
  • HD2 filter for the MS 261
  • HIGHLY POWER-EFFICIENT. With the STIHL 2-MIX™ engine, you can reduce exhaust emissions and fuel consumption, and therefore operating costs. This 2-stroke engine is low-maintenance and uses fuel efficiently even at high power levels. Use a mixture of petrol and engine oil as fuel. The STIHL 2-MIX™ engine complies with the strict EU Stage V emissions directive.
  • STIHL 2-MIX™ engine.

Great toy!
Size: Medium, Style: Ultra Tug
We have a 1 yr old rescue (German shepherd mix) and she didnt really know how to play with humans, she was scared of everything. We got this toy to help us teach her how to play fetch and tug of war and it really helped her come out of her shell. She loves this toy! It is very durable and fun to throw. Just enough rope to tug with her and doesn't come apart like other rope material. We got medium size and prob buy another one.

Durable and fun
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
This is a cool toy. My dog took to it right away. It tosses great. I like that you can play a little tugging along with fetch. We mainly use it outdoors. It feels very strong and durable. For size reference my dog is a mini golden doodle and weighs about 30lbs.

Durable
Size: Small, Style: Ultra Duo Tug
Well, our dogs didn't end up playing tug with each other, but they love the toy anyway and it still looks pretty good after a month. That doesn't sound like much, but they both love to chew and destroy rubber and they're ridiculously good at it. They also really like chewing the strap between the two balls, which is still in surprisingly good condition. Most "indestructible" toys are toast within the hour. Well worth the money. Plus, the unpredictable bounce when thrown keeps the dogs busy.

Good quality ball for large dog, easy to clean
Size: Large, Style: Ultra Tug
It’s challenging to review this because I bought it for my son’s dog, and it doesn’t interest him at all, even though he likes and plays with regular balls. The ball appears to be good quality, which is typical for this brand. He likes to play tug of war, so I thought the combination with a ball would be a hit. The strap looks durable, so time will tell if he develops an interest in playing with this at some point. The ball is hard rubber and fairly heavy, so it should hold up to an aggressive chewer. It doesn’t squeak or make any other noise. It bounces unpredictably and erratically because of the attached strap. Both the strap and ball are easy to clean with soap and water.

A must have if "ball is life"
Size: Large, Style: Ultra Tug, Size: Large, Style: Ultra Tug
If ball is life for your pup this is a great option! Our 70lb mutt is obsessed. We got her the large size for reference. She is not a chewer so we have zero issues with the attached leash/rope part. The ball is the same hard rubber of a typical Chuck-it ball. The rope makes tossing and grabbing the ball from your dog so much easier and cleaner. I also love this helps avoid any choking hazard with typical balls having the rope.
