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.

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

Kind regards,
Tony


Sometimes there's a pin securing a shaft to a gear/sheave that's
designed to shear in order to save other parts from suffering severe
damage... a shear pin acts in lieu of a much more expensive
slip-clutch assembly. A shear pin is typically tapered and costs
under a dollar... wise to keep a supply handy. They are usually
located in an easily accessible place, check your owner's manual. A
shear pin is of a softer steel than the parts in secures... in
mechanical assemblies it acts like a fuse in an electrical circuit.
