JD 4700 Curtis Cab rehab

[radios1]

How can you tell if it is powder coat? I just purchased a 4310 with a curtis cab, same issue.

paint is very glossy, powder has more texture to it. and is much thicker. How to Determine if Coating is Powder or Liquid |


Products FinishingBTW, because of poor prep work, the paint peels off after a few years.. it should not be doing that, and also, I've never seen that with a powder coating..

I'm thinking that after a certain date, you can figure your misfortune, that it's powder coated.

I made a deposit on a 2000 John Deere 4700, Power Reverser, 4x4, 400X loader, Curtis hard-sided cab. The tractor is about 7 hours away and I will be traveling to do a final inspection and if OK, purchase and bring it home next Saturday. The tractor has 608 hours on it and appears to be in very good condition. The only known issue is the peeling paint/rust on the cab. The dealer sent some close-up photos of this. The dealer stated that there are no holes, the metal is solid. I am wondering what the best approach is for repairing this. I'm thinking it would be best to remove the rubber gaskets and glass, but I'm not sure how feasible that is (in terms of being able to reuse the gaskets or availability or cost of replacements). In terms of equipment, I have an angle grinder with wire wheel, various electric sanders, and pneumatic needle scaler. What are the best products to use? Should I use a product like POR15 or should I wire wheel the rust off and just use a regular primer then paint? Should I use OEM JD paint or would another brand of matching color be as or more desirable? Thank you.

I just went through this with my Kubota Curtis Cab. I would check with your dealer to see if they can get you a parts breakdown and pricing from Curtis.

I wound up making new doors for mine after finding that Curtis wanted about $900 ea per door plus tax and shipping and a 8 week delivery time. I think I paid about $200 for 4x8 sheet of 16 ga at my metal place and you can get 2 doors out of it. The windows will definitely have to come out, you can do this by prying out the rubber gasket surround.

I had no issue reusing the gaskets, they are thick and fairly pliable.

McMaster Carr has some of the weather stripping you will probably need.

Good to know re: removing and reusing the gaskets. I don’t think I’ll have to replace any steel parts, based on dealer description and photos it’s all just surface rust. I will post progress on the work in this thread when the time comes.

Does anyone have any feedback of primers, paints, etc.?

I just touched up the cab on my 4400 with a curtis cab. Best way to attack this to go after it with a putty knife. you will probably pull off some flakes that had lost adhesion to the metal. Then I just hit it with a wire wheel and brushed on rustoleum implement paint. The color match was perfect. I also went and painted the roof green because that yellow just annoyed me. Did that with the same paint and a roller. It's not show quality finish doesn't but good enough for a piece of equipment that is supposed to be worked.

you'll sell it one day, and wish you didn't have to take a hit on the price because the paint got messed up..

Most likely not. The reason I bought this older 4400 is because the loader and other attachments worked with the 4310 I already had. I have absolutely no intention to upgrade. Personally I have not seen any innovation from the tractors I have to current models that would make me want to sell/trade. For me, my tractor is tool just the same as a wrench or a shovel. I take care of it so it will perform when needed and keep it in good working order.

I merely offered a suggestion. If someone wants auto quality paint repair for a tractor cab it is definitely feasible but be it is also more time consuming and costly. Filler, spot potty, urethane primer, and then acrylic enamel or BC/CC if so desires. Then wheeling the overspray etc. Honestly time wise it might be easier to just repair the whole cab. The thing is with these cabs is they rust where gasket wraps the metal edge where they trap water. So even going with a full restoration I am not sure how long it will last.

Given that the 4400 is a 20 year old, 35 hp tractor, I would say that anything that's painted and not rusted is a positive on resale value. Actually, if you brush on Rustoleum with a quality brush and add a bit of Penetrol to smooth it out, you can get a surprisingly good quality result.

I've had good results with "rust converter" and then spraying on JD touch up paint. I think changing the JD colors to something else would be a negative, though..

The lower gaskets are Trimlok one piece gaskets. They are very easy to remove. The line in the middle of the gasket is the seam. You will need to open it up. A flat blade screwdriver will let you get under it. Once your under the seam you can just push the blade along undoing the gasket. The rubber will be very loose then and easy to remove. I have attached a link to the Trimlok site showing the gasket construction. Getting the seam to seal back up can be a pain. Use lots of dish soap to let your screwdriver glide along when reinstalling.
