I've been looking into (eventuially) repowering my JD420. I assumed it was the same basic tractor as a JD430, but reading up I find that the 420 uses a Peerless transaxle, while the 430 uses a Sundstrand. Also the 430 is about 6 inches longer, and 200 lbs heavier (could be difference of diesel and radiator vs air-cooled Onan B48).
I found a Yanmar 3TN diesel for a 430 on eBay, but I would be into it about $1,500 just with purchase price, new starter (owner is keeping the starter) and freight. Then there still the need for a radiator, hoses, hook up misc. etc.
When considering that the 420 and 430 are not the same machines, I'm thinking of going for a different engine.
A friend has a Toro 223D Groundsmaster mower with a Mitsubishi L3 engine--I think. It's a 3 cyl water cooled diesel--the cooling fan is run by a belt driven shaft that runs over the top of the engine. I haven't been able to find any firm information on which engine is used in the 223D, nor much about the L3 engine.
I went on Toro's websiteto to look for manuals but they require the model number from the data tag, and not that from the decal... it's 40 miles away, so not readily available.
I'm thinking of using this to repower my JD420 when the Onan gives up the ghost--or sooner if fuel costs keep rising.
I've read through the threads about Mitsubishi engines here on GTT, but haven't found much information.
I seem to recall a post from over a year ago where the person said he had worked on lawn equipment and the Mitsubishis weren't that reliable, but couldn't find it again.
Does anyone have any information concerning this engine and it's suitability for Repower?
