What are the main features of the John Deere R43B Cordless Mower?

This mower has a long charge time of 120 mins and a run time of 20 minutes, long enough to mow a 320m² lawn on a single charge. It has seven heights of cut, ranging from 22-80mm and a large 55L fabric collection bag with a handy flap that indicates when the bag is full. The deck is aluminium and it has a three-in-one mowing system so you can choose to collect clippings, leave them as a mulch on the lawn to feed the grass or discharge them from the side of the mower, back on to the lawn. It comes with a safety plug but the battery power level is not visible as you mow.

What is John Deere R43B Cordless Mower like to use?

The John Deere R43B came fully assembled from the dealer, so there was no battling with handles or grass boxes with this mower. The handlebar height can be adjusted into three positions for different height users and the height of cut is adjusted by lifting the mower and pushing a button – this is heavier and more awkward than others with a similar design. It's quite a heavy mower but it handles well and gives a good clean cut, mowing to the edge but only on the left hand side as the discharge chute is on the right. The mower stops and beeps when the grass bag is full but for the price a battery indicator that was visible while mowing would be helpful.

Is the John Deere R43B Cordless Mower easy to store?

The handle folds in half and then flat over the body of the mower for easy storage. Carry handles on the front and back of the deck makes it easier to lift, but this is a heavy machine and most people will need help lifting and carrying it around.

Is the John Deere R43B Cordless Mower good value for money?

This mower is the most expensive mower in our test but is well built and robust, with many good features. It has a two-year warranty, apart from the aluminium deck which comes with a 15-year warranty and we think it's good value for money.

Who is the John Deere R43B Cordless Mower most useful for?

This R43B is most useful for gardeners with medium to large lawns in fairly flat gardens, as the weight may make it difficult to push it up and down slopes. Plus, it's a good option for gardens with limited storage space and for anyone who wants a high-quality product that's built to last.
