TRACTOR HP

[Gary Fowler]

Lots of tractors in fact most have a series of 3 or more that will use the same frame, engine and transmission to produce differing amounts of HP. For instance my LS P7010 (70HP) uses the same engine as the P7020 (80 HP) & P7030 (90 HP) (2010 models). The difference in engines is 7010 has no turbo, 7020 adds an intercooler to get 10 more HP and then the 7030 adds a turbo with the intercooler to get another 10 HP. Gears, frame, radiator etc are all the same. Most tractors that use the same engine could be boosted to produce more HP without any problems as long as it was done correctly. You shouldn't just start turning up the injection pump to put more fuel to the engine as you could end up blowing up the engine which would be a very expensive mistake.

So, how would one generally do this? Increase fuel flow in very minor increments while monitoring EGT until nearing the max temps for said tractor? How is the max temp ascertained?

I would by willing to try this in my 21hp B7500, but I'm not sure if its worth the risk yet. I would sure love a few more PTO hp for a tiller and other implements....

Does the B7500 have a water pump or is it thermosiphon? My B7200 is thermosiphon, and I would be afraid of over heating with any more HP. Since it doesn't have a thermostat I'm already afraid of it over heating and I do a pretty good job of keeping the radiator clean.

It looks like a regular water pump. But, I imagine a higher performance fan/radiator would solve that part of heat issue should it arise. Ive toyed with the idea of adding a high performance electric primary fan or two fans on either side of the engine cowling to remove the ambient heat quickly.
