I spent 2 weeks researching lawn mowers and opted to get Spectrum TG4OSE at a great price
I did have 1 issue putting the battery and key bracket on with the 4 screws. 3 pulled out first time of using it. Not an issue fixed in 10 mins with drill and long bolts.
Used it to cut my grass and my garden is up hill. The self drive is amazing for me.
Very happy with this mower.
Gets 10-10. Recommended.

Realy easy to start and a great price. my only quibble is that the handle height is not adjustable.
Its perfect height for me, but for my shorter wife its high, pair this with the speedy self propelled drive and she struggles to keep the front wheels on the ground.

This lawnmower is really out of this world, and the best one I ever had. The electric start is just like starting your car, even the pull cord recoil start is effortless. Took half an hour to fully assemble with clear instructions. Nicely made all round. I give it 6 stars out of 5! Before it was hard work for my 140ft garden, now I look forward to mowing the lawn and wish the grass grow faster! And for the price you’re just about able to buy another manufacturer’s recoil start mower only. Highly recommended mower.
