Briggs & Stratton review: Appauling service

I purchased a Toro Time Cutter zero turn mower with a Briggs and Stratton 8240 Exi 724cc engine in late July 2025.
After the first operation of around an hour and a half, I noticed a pool of oil on the plate under the drain plug and with further inspection I found that it was dripping from a crankcase bolt behind the drain plug, but this bolt was tight and not the problem.
I then took the machine to the nearest approved dealer for repair which incidently is a one hundred and eighty mile round trip and not covered by the warranty, only to find that the dealer required a £68.00 deposit before starting to fix the problem, as I had not purchased the machine from this dealer.
So now we find that there is in effect no warranty at all and no provision to contact Briggs & Stratton for customer service or complaints.
