The new Cobra Fortis 17B is a tough, self-propelled petrol powered cylinder lawn mower. Offering all the power you need to keep your grass looking its best this model offers a first-rate finish and has been designed especially for medium to large lawns. Part of Cobra’s excellent cylinder range it is ideal for the impassioned gardener who yearns for the perfect lawn.
The Cobra Fortis 17B is powered by a hard working and robust 4hp Briggs & Stratton XR550 Series™ engine and thanks to its recoil start it is quick and easy to get going, even on damper mornings. Briggs & Stratton engines are known for thier reliability, durability, and efficiency, making it an ideal choice for powering lawn mowers. You can fill this model with the latest E10 fuel and being self-propelled you won’t need to push, saving you effort and preventing you from straining yourself. The handles can be folded down for when it's in storage or being transported, which is another great user-friendly feature.
If you want an efficient lawn mower that can achieve those classic British stripes then look no further - this outstanding Cobra Fortis 17b offers a winning combination of a cast, ribbed, split-differential rear roller together with a steel front roller to ensure your lawn is given the Stately home makeover you’ve been dreaming of. Get the croquet set at the ready and send out the invites, as once this lawn mower is let loose on your grass you’re going to have the best lawn in the neighbourhood!
You’ll soon appreciate all the great features on this Cobra Fortis 17b such as the excellent BBC (blade brake clutch) system which means you can leave the engine running while you need to step away from the lawnmower or for when you need to manoeuvre over a patio or gravelled areas. The blades stop, but the engine doesn’t, meaning that you don’t have to keep stopping and restarting the engine.
With a scissor-like cutting action the six-bladed cutting cylinder offers a remarkably neat and precise finish and the generous 43cm (17") cutting width allows you to achieve this in record time. The rollers allow for a bit of overhang which means you can get up close and personal with your flower beds, leaving a neat finish even on edges. The blades won’t scalp the lawn and the front mounted 65 litre grass box is filled efficiently meaning you only need to make the minimal numbers of trips to the compost heap to empty it.
The Cobra Fortis 17B has been built to be versatile and this is thanks to several features such as the cutting height that can be easily adjusted with a small screw from a super low 4mm right up to 30mm which means you can cut the lawn any way you want, but you are always guaranteed of a prize-winning finish.
Another excellent feature is the interchangeable cassette system which can be swapped for a wide variety of optional lawn care accessories, such as a lawn brush, turf rake, scarifier, aerator, verticut, a 10-bladed cutting cylinder and a dethatcher, making this one of most versatile lawn mowers on the market today. You can even replace the smooth roller for a grooved one, in case the striped look isn’t what you want.
Say goodbye to uneven lawns and time-consuming maintenance - the Cobra Fortis 17B cylinder lawn mower is the only tool you'll need to achieve a perfectly-manicured lawn.
Benefits of using a cylinder lawn mower
Precision cutting: Cylinder lawn mowers are designed to cut grass using a scissor-like action that creates a clean, precise cut. This results in a neatly-manicured lawn with a consistent, even finish.
Healthier lawn: Because cylinder mowers cut the grass cleanly and evenly, they help promote healthier lawn growth. By reducing the risk of damage to the grass, cylinder mowers can help prevent diseases and other issues that can weaken the lawn.
Striping effect: Cylinder mowers often come with rear rollers that leave a striped effect on the lawn, adding a professional and elegant finish to your lawn.
Low noise levels: Cylinder mowers tend to be quieter than other types of lawn mowers, making them a good option for those who want to mow their lawns without disturbing their neighbours.
Low maintenance: Cylinder mowers have fewer moving parts compared to other types of lawn mowers, which means they require less maintenance over time. This can save you time and money in the long run.
Overall, a cylinder lawn mower is an excellent choice for those who want a precise, healthy, and professional-looking lawn, while also enjoying a quieter and low-maintenance mowing experience.
