- Installation of heater in my newly renovated and fitted Curtis tractor cab. Also, a simple modification to restrict the air being drawn into the radiator and engine compartment and keep warm air inside the cab of my JD 425.
The heater in my 425 with Curtis cab will keep ya warm in below zero weather, love your engine block heater, that will be my next install
That plate was genius!
Well done! I like the neat plumbing job and the radiator air restriction plate is genius, Semi truck use restrictors when it’s cold, but since the engines are turned 180 in the 4x5s, I didn’t even think about it. Thanks for doing these videos,
Thank you. By restricting airflow from the cab to the radiator, it not only retains heat in the cab but means the engine warms quicker and stays warm in very cold temperatures. Glad you like it!
nicely done video. thank you for sharing! i enjoy all your videos. i love seeing people overcome all the troubles the tractors cause us. i never dared mess with the cooling system i use a couple little propane heaters in mine. i also block off my airway as well in the winter with that silver bubble stuff from the inside. what a huge difference it makes to not suck all the air out.
I put electric fan on mine and blew the radiator heat back into the cab works pretty good.
Lots of good info there sir I will surely save this in case I ever get a curtis cab for mine
I’ve said it before I know but I am very envious of your situation haha
Right now my 455 is in parts as I am doing a complete renovation. Mechanically I’m done and the center section has been glass beaded and painted so by spring I should be ready to go shiny and new with new decals and all. I love this diesel in the 455
That 455 Yanmar is a very nice engine. You'll have a great tractor when you're done restoring it. Good luck with it.
For those who needs to tap into the John Deere temperature sending unit to add a cab heater, the threads are M16 x 1.50mm (confirmed on JD 322, 332). You can get what's needed from McMaster Carr www.mcmaster.com
Parts needed:
1 - P/N 4936K156 Adapter, 3/8 NPT Female, M16 x 1.50 mm Male Thread ($8.77 Each)
1 - P/N 4936K864 Adapter, M16 x 1.50 mm Female Thread, 3/8 NPT Male ($25.82 Each)
1 - P/N 50785K223 Right-Angle Tee Adapter, 3/8 NPT Female x Male ($7.21 Each)
1 - P/N 53525K22 90 Degree Elbow for 5/8" Hose ID x 3/8 NPTF Male ($7.58 per pack of 2)
Also needed for the radiator return line is a 1" x 1/2" x 1" copper pipe TEE for a 5/8 Heater hose.
Hope this will help those who are looking for solutions in their cab heater project.
Cheers

Good information. Thanks!
what my friend did for the lower hose coupling was , Use a double ended barbed steel coupling,which would go into the hose, and then he welded a circular bung in the center of the coupling so he could drill and tap it to take another barbed connection into it to take the return hose.
I considered various methods of hooking up to the coolant system and decided simple Pex brass barbed fittings, connectors and tees, was the easiest and most cost-efficient way to go.
nice cab heater. I think if you turn the cooling fan around for winter the radiator will help to heat cab.
Nice idea, but unfortunately, in a closed cab, I think that would be very risky. The fan could pull fumes through from the engine, etc.
Is it possible to just flip the fan and have it blow towards the cab? I have a Original tractor cab so it doesn't seal as nice so not too worried about fumes and whatnot since there is still plenty of fresh air comming in from all of the gaps.
Nice video! I have been watching your videos for a while now and you have sold me on the Little Buck Loader. I am buying one for my 425 very soon. Would you be able to make a removal and installation video for the 4-5 series. Thanks
I am glad you find the videos helpful. It will be awhile before I can do more videos like that (had hip replacement 2 days ago!). However, if I remember correctly, the LBL website has a short video on fitting and removing the loader. I think they show an X7xx, but rhe process is identical for a 4x5.
Thank you for the info, I hope you have a fast recovery!
Great video! If I may ask, what was the total time taken to install everything?
Recently found you video regarding the Curtis cab heater, and I was inspired to instal one, I just finished the installations and after running it for a quite a while I'm not getting enough flow to the heater, I was wandering if you have any idea what it can be??
what is the sheet of diamond plate over your radiator? where the debris screen is usually located? is it to keep the cab warmer in winter? any drawbacks?
Great job nice and neat, I have the same tractor what are your thoughts on reversing the fan so the radiator hot air blows in to the cab.
I'm trying to figure out if this is possible because I would like to blow the radiator heat into my cab.
When I'm out blading or blowing on a cabless X585, I've always wondered if someone could come up with an alternate fan blade that would simply reverse the cooling airflow, thus heating the operator's station. It may help keep me a little warmer if the wind isn't too bad. Just wondering if you have heard of that being tried.
I think that is very possible, as follows: Replace the mechanical fan and shroud with a thermostatically controlled electric fan unit, which are easily available and much more efficient Then have a switch that can change polarity when required, and override the thermostat when necessary, to blow hot air towards the driver. I actually thought of this for heating the cab, but the liklihood of blowing exhaust fumes into the cab would be too much of a health risk!
Great videos. I just purchased a curtis cab for my 425. Would you be willing to send me the pdf for installation you got from John at curtis?
Hi Tesser you might be able to connect a electric fan which hooks to the radiator with a sensor for on and off control. There made for cars or on sites like jegs.
Thanks. Yes, I think I mention in the video that at sometime I want to do away with the mechanical fan and fit a thermostatically controlled electric fan. It would save engine power and be much more efficient.
Have a few questions about the bottom tab on the sides of the floor pan if you have to drill holes on the foot pan
The side windows that attach to the front supports, do have bottom tabs. The outer edge of the tractor foot wells do need to be drilled (single hole either side) to bolt and secure those tabs.
I want to buy a lower radiator hose heater for my 425. Do you recall the inside diameter of the lower hose so I know what size heater to get?
I fitted the Kat's 1.0" diameter 400 watt heater to my 425 and 445. I show the installation in one of my other videos. The ID of the lower hose is slightly larger (probably 1.25") but I find the 1.0" heater works fine.
@@tesser5250 Thanks
Were did find it
I think the video explains everything...
@@tesser5250 IT SAY WERE BOUGHT IT
Hey could anyone give me a few points on getting the cab on my 425
Have you checked out my other videos on restoring and installing the Curtis cab? You may find that helpful.
@@tesser5250 ya I watched them but you didn't go over the foot well the flangeon the outside of the foot well
You should have front mounting brackets that bolt to existing holes on the tractor frame below the foot wells. Do you have the Curtis instructions? You may find them helpful. If you don't mind providing an email address, I can send you a PDF.
