Rear and quarter defogger/defroster

[arsenix2001]

Well when I ordered my 3540 i got every option i wanted except a third function, a rear remote and the defrosters... Las minute i decided to get the the rear remote for a top link and ditch the idea of the defoggers... Mistake. I am so fed up with the fogging of the rear windows i ponied up and ordered the rear and quarter window kits from my dealer for around $500. I am going to install it myself. For those who have it, will this finally solve my woes? And is it hot enough to de ice the glass? Lastly it seems i have the pigtails by the windows already, and there is a couple empty relay plugs behind the dummy switch plate in the cab. So should this be as simple as swapping glass and plugging in the switch? Thx!

Have you tried cracking the quater windows a bit? That and pointing the heat ducts seemed to help on my L4240. Those defoggers were the only option I didn't spring for also. Interested to see what others have to say...

Last year I had the same problem ,cab windows fogging up . Just passing on some good advice from some good old boys .
When you use your heater ... put your AC on to. It really works good, (it takes the moisture out of the air) and turn down the heat so it's not all the way in the red. Hope it helps ,it did for me.:thumbsup: You might have to play with your vents alittle before you get the air to go were you need it.

Yup..Turning the AC on helps alot in my RTV1100...Aiming the vents helps too.

Yeah, ive been trying that, it definatly helps. I also set the recirculate to fresh air. Ill report back on how well the defroster glass works if it ever comes in... They are saying kubota wholegoods could take a couple weeks:thumbdown:

Sorry ,I forgot that switching the fresh air on instead of recirculating the cab air works good to.:thumbsup:

You guys without the side/rear defrost option, does making adjustments to the vents, cracking windows and a/c on make fogging a non issue or just better. My question, is the defrost kit a waste of money? If you had it to do over would you add it to the options list?

Thanks,

I have the rear window defroster in my B3030 (came that way when I bought it used). It works great, it actually gets the glass warm enough that I can feel some heat coming off of it on the back of my neck.

I definitely consider it worthwhile when snowblowing.

I am not sure if the rear window on the L cabs is similar to mine, but if I open the window I have to unplug the heater tab from its cable first or the window pulls it out on its own. I worry that could break the tab loose one of these days. I hardly ever open the rear window and keep forgetting about it, but one of these days I hope to remember to see if I can loosen up the cable to give it a bit more slack. May be something to think about when you install it.

Thanks for your post!
Great feed back!

My pigtail comes out at the top of the rear glass so im assuming opening the window wont be an issue. Worse comes to worse ill add an extension I guess. I wish yhe kit were here, were getting out first measurable snow of 6-10 tomorrow and I wanted to try them out!

From what i remember reading it uses a timed relay... I dont know that i would want it on all the time, rear window maybe, but rear and quarters i would imagine is quite the load on the charging system. Especially when you throw in front, rear, head and tail lights... Radio, wipers etc. Plus it is dummy proof in the sense you wont be summer heating your glass. Either way i would imagine if you found a diagram you could probably rewire it for a standard switch and relay setup.

I am not sure how your B3030 is wired but something doesn't seem right. I have a B3030 and can open the rear window without unpluging the rear defrost. I would think you should be able to do the same.

That's what I was getting at. I'm sure I shouldn't have to unplug it, but I do. The wire is on the top of the glass where it is hinged and looks like it belongs there, but it gets pulled tight by the amount the top of the glass moves. Hard to describe I guess. I am assuming it isn't supposed to be that way and somewhere in it's past life before I owned it the wire got pulled too tight somewhere between the switch and the glass. It is probably a simple fix but I only think of it when I open the window while using it and then forget about it before I have time to look into it. If it wasn't 10 degrees out I would go fix it right now while I was thinking about it. I only mentioned it as I figured it would be a good thing to check while he was installing the kit.

I didnt get the quarter and rear defrosters in mine and I dont have any issues at all with them fogging up, when I warm mine up I get the inside of the cab good and warm and then after a few mins I start to cut the heat back till I get to my comfort zone, mostly I run mine on level 1 (once its good and warm in the cab) with the temp range at about 1/2 way and I havent had any issues with them fogging. I do it that way because I operate a CAT D6R WX at work and they dont come with the defoggers so ive had alot of practice with this situation.:thumbsup:

I have the defrost on the rear window but not the rear sides yet, but I'm going to . The truth is the only time I use my rear defrost is if it's snowing out (melts it fast)or I want to clear up the window quick, or if there's ice on it. Most of the time it's just the vents/AC/ heat on low-mid. and that works good. I could maybe see if it was really cold outand you wanted to put some of the vents pointed at you ,then the defrost would help alot. I have to say most of the time you couldn't run your heater on high for long or it would drive you out, even if you had a t-shirt on.

 

[arsenix2001]

I can be out blowing snow for 5 to 7 hours at a time and even with the A/C running it can still fog up inside without the defrost running. This may in part be caused by snow blowing back on the glass. I am in the cab in shirt sleeves, but still have to keep the temperature control about half way between cold and hot or I would melt in there. At times I will open a side vent window but cannot always keep them open because of the blowing snow.

You nailed my problem completely. I get so darn hot inside trying to deal with windows. I just want to hit the switch and then let the heater worry about heating me lol.

I gather from someone's comment here that the B3030HSDC has a REAR defogger as an option, but does it have defoggers for the rear quarter windows, as well?

Are the defoggers the "grid style" of wire in/on the glass, or a force air type?

Can things like a rear wiper and defogger (and rear quarter defoggers, if they exist for the B3030HSDC be added by the dealer, or must the tractor be ordered that way, from Kubota?

Thanks,

My Hoe

The B3030HSDC just has a back glass and the side glass but not the rounded quarter windows as on the L series tractors. The rear wiper and rear defrost can be ordered as a dealer installed option. The rear defrost is a new rear glass with the "grid style" wire in the glass. It also comes with a heavier alternator.

Kubotafan,

Thanks for the education, and explanation--I didn't realize there were no rear quarter windows, either--much appreciated!
