Slider element not responsive tablet / mobile

Hi there,

Hope all's well.

Hope you can help. I've added a slider element to my site (here for example: http://hortumlandscapes.co.uk/lawn-turfing-service-west-london/).

Looks great, but when I view on tablet or mobile it is cut off / not responsive.

Is this normal? Any way, other than remove and replace with a static image? Hope so!

Screenshot example attached.

Thanks
Kevin
