I have spotted my first under £100 petrol lawn mower of 2014. The Original Factory Shop are advertising a Q Garden Petrol Lawnmower for £99.
The Q Garden Petrol Lawnmower is a 40cm petrol rotary mower which comes with a 40 litre grass collector. They say it is fitted with a 99cc T475 engine. I have tried searching for the T475 petrol engine and it looks to be a Chinese made four stroke engine.
If I was looking to buy a low cost 40cm petrol lawnmower as well as this model I would seriously consider the slightly more expensive McCulloch M40-450C which has a steel deck and a Briggs & Stratton Engine.
