Love it

Extremely easy to set up and use, lighter in weight than my previous mower. Maneuverable and compact. Very happy with this purchase

Very good product

I bought this mower last month and found it very good just needs different fittings for the grass box not screws and washers

Excellent mower

I change my lawn mower for a self propelled one, wow! What a difference. It cuts the grass to the desired height as you can adjust the height of the mower. Good capacity to hold all the grass, light weight as it pushes its self around, easy to manoeuvre. Easy to clean, the grass collector is easy to get on & off. Automatic throttle so you don’t have to worry about adjusting anything, easy to add oil & petrol. Over all a fabulous mower, I’m very happy with it

Good Product

I bought this product last month to replace the same model previously after 8 years of good use no problems. This replacement does not have the manual choke, it does not fire up as quick as previous mower. Still works well though.

Great

It’s a slightly bigger model than my last Mountfield, and it is so easy to use and leaves a great looking lawn

Bought a lawnmower.

I have had one of these lawnmowers for the past 6 years and I wanted to stay with the brand. As a woman this machine is effective, can deal with small gardens (the manoeuvrability is great due to the weight) and powerful enough to get through over grown grass. Has a mulching plug and folds down if you need to pack away in the shed or car. Only put 4 stars for price, as I always want to spend less money.

Mountfield mower

Bought this lawn mower as a replacement for our old mountfield, was disappointed with the handle set up, the two locking nuts , broke during the first use, preferred previous set up, lucky we could tighten and continue using but unable to fold the handles down, se be very careful using the butterfly type bolts made of plastic, other than that easy to start and operate

Super Mower

This mower is excellent. Motor driven so no effort when mowing the lawn. Highly recommend this make and model.

MAB1978 - 5 / 5 - 22/11/2023

No issues

I bought this in April 22 - I did have to watch a YouTube video to put it together and particularly the grass collector (I see another reviewer hasn’t managed to fit it properly yet. When it’s fitted properly it doesn’t fall off or drag along the ground. I have a 200 ft long garden which isn’t particularly even ground and it’s not a big garden but it takes 30 mins to mow from start to finish if I’ve kept on top of it. I find the mower easy to start and have never had anything randomly fly off it. I have it drained at the end of the grass cutting season and get it serviced and blades sharpened in spring. All good.

Disappointed Gardner.

The clutch mechanism is useless, There is no smooth engagement, stop to full speed ahead with the slightest movement of the control bar. Very disappointed and will be happy to replace it after six months. It is also a very heavy weight and difficult to manouvere for for an 81year old.
