Diesel Boosts Power, Fuel Efficiency In Deere 4020

Diesel Boosts Power Fuel Efficiency In Deere 4020 ENGINES Engines Jim Lumbrezer s Deere 4020 has more power and uses less fuel since he replaced the old gas engine with a diesel
     The fuel economy is just unbelievable I used to use 8 to 10 gallons an hour says the Swanton Ohio farmer Now I use 4 to 4 1/2 gallons an hour
    Lumbrezer says there were several challenges to install the 404 diesel engine from a Deere 4230 into his gas-powered 1967 Deere 4020 Because of the size difference of the engines he had to add a few inches to the frame which also meant lengthening hydraulic pump lines and steering lines
    One of the biggest challenges was the flywheel The ring gear on the flywheel was different Instead of buying another flywheel I took it to a machine shop and had it cut down Lumbrezer says
    Using the same flywheel also saved him from making changes to other parts For the clutch for example he just replaced the pilot clutch bearing and clutch disk to match it up to the diesel engine By changing a bearing he maintained the dry clutch system in the gas tractor He also used the alternator and ignition from his old tractor
    Both systems were 12 volt but Lumbrezer added another battery for more starting power for the 120 hp engine
     I had to add weight to the back otherwise it would just spin because of all the power he says
    He bought the engine used and spent about $2 000 for everything That was six years ago and Lumbrezer says he s put 2 000 hours on the tractor since then doing fieldwork
