The day before the rotavator was due to arrive I was telephoned to say they didn't have the heavy duty rotavator I had ordered but were going to deliver a medium duty rotavator and refund the difference. I needed the machine before the rains were due, so I had to accept this. The machine arrived on time and I managed to get the ground prepared, albeit, I believe, with more difficulty than if I had got the machine I wanted. Although the machine was delivered late in the day, it was collected early in the day so I did not have it for the full 7 days, although the job had been completed.
