<font color="red"> did find a magnetic heater on the Internet - I think it was 200 watts - I was going to order that - where do you guys think is the best place to put it on a 425? - to get the hydraulic oil tank -
should i put two on - one for the hydraulic fluid , one for the engine pan??
Do you think the heater will work??

Ed: As you can see, Hans had to go to some lengths to get his 425 going. Of course, he had to spend Thursday, Saturday and Sunday nights plowing and spreading salt.
To get the 425 going initially, if you can't get it inside a heated area, I'd recommend a heavy tarp (tent) and a 1200 watt heater (Home Depot - cheap) for a couple of hours to try to bring the whole thing up to temperature. Then, fresh spark plugs and good jumper cables to a running vehicle. If it doesn't light immediately, you'll know for sure that there is something else amiss.
I'd bet that a magnetic heater on the hydraulic oil and one on the engine oil would normally do the job if everything else is in good shape, but if you're talking temperatures near 0, 200 watts each might not be enough. Certainly a blanket or tarp to keep out the wind would also help if a heated garage isn't available.
(The Deutz is really impresive, isn't it? Only diesel I've ever had that starts in cold weather without a lot of cussing. It's hard to believe we're posting solutions for balky gas engines with the 1845 diesels starting without heat or ether.)
