What’s in an engine?
You can buy a Briggs or Yanmar engine or you can buy a Deere for instance, with a Briggs or Yanmar in it.
What’s the difference?
Tolerances. John Deere might very well tell an engine supplier, “We want tighter specs.” And they probably do.
Tighter specs give more consistent performance. Specs may be the difference between a seal leaking prematurely or not leaking at all.
I’ve pulled lots of engines apart from VW’s to Porsches and while the Porsche may have more gussets, external oil tanks and other fancy racing stuff you can still get piston manufacturers who sell pistons for both engines and can essentially have a very respectable four cylinder VW pancake engine in an old ‘Bug’. It’s not magic any racer will tell you that a blue printed engine is better . What’s a blue printed engine? One that is exactly that and that is to follow the blueprint. (usually the tighter tolerances of the blueprint especially in racing engines).
An engine supplier may run a carbide borer to its limit or beyond before changing it. The better manufacturers change cutters when they should. Toyotas made here are made by the same type of people that make other cars here but Toyotas hold up because they are tighter.
Here’s another tidbit. Buy a VCR from Wally world and the same one from a supplier who doesn’t have the buying clout of Wmart and you get two different machines. Wmart actually tells suppliers to cut corners on parts or do what ever they have to in order to meet prices Wmart sets. Think about that the next time you want a TV.
What kind of a tractor did I buy? I bought a John Deere. Cost a little more? I think that’s up for debate.
