Would it be possible for the warden to turn the tractor off whilst cleaning a service point to lessen the noise?  I've been twice in recent weeks and both Sunday mornings the tractor has been left running for 15-20 mins outside my motorhome whilst - a very good job is made - cleaning / emptying bins. Also it's not very 'green' to leave it running. I visit the site a few times each year and it is in a great position for London or nearer towns. I didn't use the shower block this time so things may have changed but, last time, an upgrade was way overdue. Thanks.
