Hi....I inherited an Atco Commodor B17 Mower with the house we bought.
It has run fine since last August.
This year, I have noticed it seems slightly noiser(and I mean slightly)
than last year and seems to struggle through grass when it gets
something like "long".
Yesterday, After up and down the lawn twice, it slowly got slower and
slower till it stalled.
I tried to restart it with the pull cord and it nearly broke my
wrist.
The engine seemed to have seized.
After about 15 mins, it "unseized" itself and I was able to start it.
Again, after 3 or 4 times up and down the lawn, it ground to a halt.
Seized again.
This now is the norm.
From "cold", it will cut for maybe four or five minutes and then
seize.
Someone told me to put 2 stroke oil in the petrol which I have but it
doesn't seem to have done much to help.
Whats wrong here???????
Why does it seize after a few minutes running and why does it unseize
itself.
Why hasnt it done it for the last 10 months?
Is it the engine itself at fault or perhaps a bearing seizing when it
gets hot?
How can I fix this problem please?
Many thanks in advance.
OK, the obvious question is...is it out of oil? It's acting like it's out
of oil. If the oil level isn't low, maybe it isn't getting circulated
somehow. I would think a mower would be splash type lube, but maybe it has
an oil pump bad? Oil line clogged? -Dave |
As Dave said check the oil and/or top it up or replace it with the correct grade.
And also check it is getting enough cooling air. "Heat seizure" is pretty common due to lack of cooling. May also pay to check the spark plug for the colour at the tip, as a too lean a fuel mixture can cause overheating in extreme cases.
Good luck
