No I have just run a few foundries in a previous life and was responsible for QC at another plant, so I know how things work.
The biggest casting machine I ran had 140 moulds on it.
People have the warm & cosy vision in theri heads of a couple of blokes in leather aprons & spats with a ladle on a long rod.
The machine poured 3 tons of aluminium an hour and had two rotary melting furnaces feeding it.
So if you had a duff patern you just had to run with it and rely on your furnace man to pull the known bad ones out as they went past and toss them into the trimmings ling to go back into the pot.
The castins get some checks then are packed in stillages and sent to the factory.
Our gross profit was $ 800 / ton and these were the good times.
So if Kohler have 1 in 100 that might be a problem then they become a warrantee item.
Those well away from the coal face can take a high minded stance but in the cold cruel real world things are different.
Kohler probably make better than 1,000,000 of these motors each year so some will be faulty, that is the nature of manufacture.
In the 2 years I have been on this list yours is the first case that has come up.
If it had come up before then we would have alerted you to it and there are a lot of certified Kohler techs on this forum.
Hustler on the other hand would have known of this problem from the first time it occurred and they would be making warranttee claims on Kohler, just the same as they would do with kawakasi or briggs or any other engine maker.
naturally from a PR point of view the Hustler rep is not likley to tell you that knew there were problems with some of the engines but we sold them just the same, they are going to blame Kohler and I would not expect them to do any different.
At the price Hustler pays for these engine there is not much profit in making them so every decision is an economic one.
Hustler went with the Kohler because it was cheaper for them to buy than the Kawakasi and the kawakasi was previously used because it was cheaper than the Honda and Honda exited the market rather than downgrade their product to the level that Hustler was willing to pay.
Thus Hustler can offer a mower at a better price than whoever they see as their main competitor for this machine. An economic decision.
That is the reality of the world we live in.
Nothing condesending about it.
All the best mower makers have either downgraded their product , gone out of business or outsourced to China.
And the only reason for this is Joe public will not pay a reasonable price for their products.
Unfortunately you are the customer who got not only the bad engine but from a dealer with poor customer service so you got the double whammy .
Quite justifiably your are angry about your situation, but unfortunately it is the way of modern commerse.
