I have a Castel Garden tractor with a 1 metre cut. They are sold under
a number of
different names like Westwood etc.

Anyway I was finishing the last cut of the year (hopefully). And a
warning beeper started to
sound. This only occurred when the cutters were engaged.

I could stop the cutters and then restart them and the beeper would
start again after about 30 seconds.

It still seems to cut ok. Just wonder what I should be looking for.
Belt need adjusting or something. Anybody had anything like this?
