As I said it doesn't owe me anything!

I have a good quality "Harry" with a diecast deck and huge grass box,
19" cut. Anything similar would cost me a fortune. When my engine
died (valve seats came loose in the head) I got a replacement Briggs
and Stratton and dropped it in. It has been going another 10 years
since. A lot cheaper than a new mower - at the time it was 45 quid
against 350. Briggsbits do the full retail price, but it is possible
to get them much cheaper than that. My local tool hire shop sold me
one recently for a mixer - official price 120, they sold it to me for
75.

That said, If you want a new mower I would recommend a Harry, although
only one model in the current catalogue has a rear roller rather than 4
wheels. www.fgm.uk.net appear to be the importer
