Default Suffolk Punch Lawn Mower Problems

Hi,

Recently bought a Suffolk punch petrol cylinder mower and all was great
for 6-8 weeks.

However, I started using the mower last week and within a few minutes of
use, the cylinder and self propel roller suddenly stopped working.

The engine continues to run fine, starting at the first time of asking
and running as smoothly as I could hope, but nothing in terms of cutting
action.

I’ve taken the side panel off and checked the tension of the belts, but
they seem okay when compared to what they were previously (that’s not to
say they are correct). But i’ve also tried pulling the cables manually,
thus increasing the tension, but still nothing. Also think it’s quite a
coincidence that both the cylinder and the self propel stopped working
at the same time. Any ideas?

Kind regards,
Tony

I've never seen that mower (that style seems to have virtually disappeared
in the US many decades back) but, looking at a diagram online, it seems
simple enough. The big question would be whether that rotation of the
engine is actually getting into the side compartment where the belts and
suchlike reside. Have you tried (carefully!) running the engine with the
side panel removed to see if the top shaft rotates? There is a coupling to
the side of the engine that transfers rotation from the engine shaft to the
drive pulleys in the side compartment. If the coupling was somehow
compromised that would give the symptoms you describe.

Watch out for the heat!
