Sure!. I fancy with 2 ideas.
First and most probable, straight conversion of the Ebro (fordson):
pros: 0 purchase cost, spare cyl head to "play"
cons: that position of the injectors, that engine suffered a piston seizure some years ago and was miserabily repaired. Just removing the pistons, careful sanding and… running until today. Probably not in her better days.
but… fordson major “clone” can be found from 1 to 2 grands and are plenty of them, so, switching the gasifier from one to another would be pretty simple and affordable.
Second: Purchasing a new tractor, same tranny but fitted with a 4 or 6 pots perkins engine, with external injectors,
pros: machining would be easy, some moder features as full closed cabin, a bit more juice…
cons: money. Purchasing cost just for tractor is about what probably would be needed for the whole gasifier setup
So, seems reasonable “fail” as cheap as possible, and go for the major…
I can do most of the conversion on my own. Probably only injector holes will be left to a (friend) machinist. I have also to do some math in order to decide if pistons needs to be shaved in order lower the compression ratio.
PS: Iv’ve followed Mike suggestion and have had a look on the adverts pages and I’ve seen in my nearby a gas tractor, a Renault e30, so 30 hp on gas.
pros: pretty damm cheap, 600 usd.
cons: total lack of power on woodgas for doing any work. Extreme rare unit here, no spare parts at all. Seems to be made in the early sixty’s and have not run in no less than 20 years… guess she is not my lady.
