That's interesting to know. I've not heard of the kits being in constant use like you've done, good to hear that it improves power with no ill effects on the engine. Might ought to check that out.

In the late sixties and early seventies propane injection was quite common on diesel tractors before turbochargers became the norm. It was quite common to see the Moline diesels with a propane injection kit on it. You heard individuals boosting HP on a typically 100 HP tractor to about 120 to 140 HP. I am not sure what the system effects would be on a turbocharged engine.

Well, if your storage tank has a "wet line" to feed liquid propane to the combine tank,and the vapor was somehow vented from the combine tank to lower its internal pressure, the higher pressure in the storage tank would fill the combine tank very quickly. Now that you mention it,I don't have a pump either.

Yeah, you shouldn't need a pump or anything. We used to have a 715 combine and a 416 cotton picker that ran on propane. We had a trailer with a 500 gallon propane tank that we used. Connect the line, open the valves, then you open the vent valve on the tank being filled and physics does the rest. Funny story: We used to have a combine driver that would carry a 6 1_2 oz Coke in the cab with him. He didn't have a cooler. Middle of the afternoon, when he would have to refuel with propane, he spray the bottle with the freezing liquid from the hose, it would get the Coke icy in just a few seconds. How he could drink that thing with the smell of lP on it I'll never know, but that was his daily routine for years.

Seems like our neighbors in the landleveling business ran 6030's that had the kits on them. I don't remember enough about John Deere's to say if they were turbocharged or not. But I'm pretty sure I've seen the kits used on 4840's in the later 70's as well.
