I HAVE (3) Deere, 425, 455A, 455C, 22 years, * Fuel, Dirty screen in the tank, Inline filter, Old Hard Bent Hose, Dirty Injector, Fuel pump Getting weak, Again screen Plugged in tank! I Clean Mine Every 5 to 6 years Gar & Diesel! FUEL IS REALLY DIRTY** Running on (1) Cyl ? #2, Bad Igniter, Amazon $95.00 Only one that works. I Have had a 425, 22 years, Now it doesn't charge, new Batt, waiting for a new reg to come in mail. GREAT MACHINES I LOVE MINE, ALL Wheel steer. Works fantastic around trees on a wooded lot. Good luck, You Tube has Millions of Deere owners & we been there & done That !!!!!!
fd620d manual state 170 psi. either side. 230pis maybe has carbon buildup/lazy sticky valve. bent push rods worn cam lobes ect valve lash is set at .010in.120pis is really common with slightly worn rings. check serial # for possibility of having a plastic cam gear.
Nice videos. The amount of compression you have seemed insane to me so I checked my service manual and it calls for 170 psi, which bis 60 psi than what you were getting, They mentioned that excessive compression can be due to carbon build-up. Thoughts? To me that engine sounds really sweet and when you consider the junk you get nowadays for 3k, won't even come remotely close to a 4x5 tractor! She's a real beauty!!
I recently bought a 425 and my oil smells very full of gas. I’ve checked valves, the needle, spark plugs and I’ve changed the oil. Do you know what possibly is my problem? I have some other questions on it as well. Great video! Hope we can talk
I have a 445 with less than 800 hours on it. It doesn't smoke but seems to use oil. Could this be the valves needing adjusting or would that be a ring issue?
The valves are always an easy thing to check and adjust (with or without oil usage). Oil useage doesn't always mean rings. It could be the type of oil (multi-weights will "burn" faster than single or heavy weights. Engine use plays a part. Along with a lot of other factors. Somewhere floating online is an oil use chart showing what is acceptable for different engines. Most engines I have seen are in the X oz per 50 or 100 hrs.

If you ever get the chance, I'd love to see a video on setting TDC and then adjusting the valves on one of the 4x5 machines.
Thanks for the video! The 4x5s are my favorites, so I own one or two of each.
did you do a part 4 of mowing with the 60" deck??
I don't think I did. I do have videos mowing with my 455 and the 60" deck under it. There is a video comparing the X748, 455, and the 400 as well.

Yes seems high. Just got my 1993 checked. Its 180 to 185.
@mmrbeef - do you have any machines available?

Hello, thanks for the great videos. I'm wondering if you or any subscribers might have a mower deck for a 425 for sale? Thanks

What platform do you use to sell your garden tractors and parts on? Craigslist, FB marketplace, etc?
I use eBay (same username), my website, Craigslist, or if you just want to send me an email and see if I have what you need.
@@mmrbeef Great, thanks for the reply
Time for some Seafoam in the fuel system. Might be a dirty fuel injector causing the stumble.
Nice video
Did u sell the 445?
Still sitting in the shed waiting for me to make a decision about it.
I tried to warn you about the plug wire lol. Doing the video and talking about it too,probably not as easy as it looks hehehe
Good morning
You need a head cam.
Why would someone choose a 445 over a 455? I imagine the 455 diesel has better fuel economy and torque. What am I missing?
I have 430 diesel and 455, and 430 is by far better machine as far as power and looks and capabilty.
try straight 30, only stuff that works on others my coworker mentioned
