450 models?

anybody have a quick and easy explanation on the different 450 models?

I am probably not the best source of information as I am still learning myself, but I will give my best explanation and anyone else that has better information can jump right in. I assume you are asking what the different letter designations for the 450 model represent (450B, 450C, etc.).

My understanding is that the the 450 crawler was the replacement for the 2010 crawler, after they ended production in 1965. The 450 (no letter following it) was the earliest series designation of that model starting in 1965, followed by the 450B, 450C, and so on (there was no "450A"- presumably this was the 450). The letters basically stand for the new improved version of the model at the time it came out.

I believe that the dozers and loaders have the same letter designations. I know that there are some advancements that were significant in the series; for instance the 450C was the first 450 model to have "wet" clutches. I am sure there are many other differences to note as well.

I think the 450 model series went up to the letter "G" in the late 80's but I am not sure. I think that was mainly for dozers; I am not sure how far the series went for the loaders, but I personally haven't seen one past the 450C. I believe the 450 model was superceded by the larger 455 model in the mid to late 80's.

I know that this was confusing to me when I first started trying to learn about them- it would be nice to find a FAQ that presents this type of information for each model of crawler. A big help was a specification web page provided by my local JD dealer; it has other construction equipment besides crawlers but has the original downloadable fact sheets/brochures complete with weights and specs. I will provide a link to it if the moderators are OK with that (please let me know).

Please fell free to correct me if anything I have presented is not entirely correct.

thanks for the help, the little bit i did know about the different models were that the 450 c had the wet clutches. i`ll take any info you have on the different models.

have been keeping an eye on machinery trader, seems my dad is looking for that PERFECT 450 the one you dont need to take out a second mortgage on, or needs work! cant blame him really, but i`d be the one wrenching on it! still not quite sure why he wants one. he does have some land he wants to clear, but not that much where hiring somebody to do it would break the bank. on the other hand i have lots of work i could use it for, so trying to help find that PERFECT machine!

Tomcat-

I found that there is a topic forum on this board specifically for links- I will post the JD brochure/fact sheet link there.

The 450C was also the first turbo built engine Yes we are into the second series in 450Js just last month small but signifigant upgrades in the computer system and a lot better fuel economy as the computer is field programable by any one that knows anything about computers.The largest improvements were in the G series with a full frame and componentized drive train that is also in the H and J series Most industrial manufacturers upgrade with a letter rather than number change A 355 or 455 is a crawler loader made after 1983 In late 74 than 75 & 76 with mixed serial numbers you could get a 450 B dry clutch or a 450B or C in wet clutch But 450C was turbo built and 3 more horse power 1974 to 1983 450Cs were built And Looks like C&D series were also mixed serial number in late 1983 as well but none of the others to date are mixed serial number [My dad had a wet clutch B in 1975 ].A lot of the northern units were wet clutch as dry clutch had too mutch condensation problem in the cold This shows up in the Construction blue book And it is acurate .

well, i`m learning! when did the 450`s come out with hydrostatic drive? did they go totally hydo then or did they continue making them with a regular transmission?
interesting that some b`s had the wet clutches.
have looked at a few 450`s for sale last summer, but beat to near death.
what about weight? did they gain much weight in later models? i seem to think i saw a weight somewhere that the 450`s are around 16,000 lbs.

Hey TomCat-

Digitup appears to be the better person to answer your question about the hydrostat drive.

As for weights, according to the sales brochures the 450s did increase in weight over the years, probably due to the addition of features like turbo. The brochures showed a weight for early 450 crawler loaders of 14,500 lbs and for later models such as 450c of 16,700. Of course, this is for the loaders. i'm not sure you ever mentioned if you were interested in dozers or loaders- there is a weight difference between the two. The bare early 450 crawlers (no blade or bucket) are shown at 11,700 lbs.

I posted the link for the sales brochures in the "links" forum if you want to check them out yourself.

Hey, thanks for the link. i`ll be spending some time on there. not only deere, but different brands i can compare with.

Tomcat the hydros are computer over hydro 5 miles per hour forword or reverse either track.And yes they will counter rotate like a skid steer and with the computer linked to the fuel rack as well the electronic fuel control monitors RPMs.So down shifting and up shifting is all a thing of the past Deere has finaly got on top again .But Cat and Deere are real close in machine specks .And realy battleing for top of the heap. After the earlyer model 550J Deere I was trying The Cat dealer sent in a new D4G and.The Deere sales man [not wanting to be out done]brought in this latest series. It out did the Cat and is a lot more fuel eficent .So two months ago I got a 550 J in the latest build Then in some wild negociations and dealings bought a second 550J tradeing three older machines in the deal and for the last week. I have been dealing on a 450J just to go with clean up behind the excavators on site prep.I will send a photo of the 450J to photo section taken several days ago.Cant pry my little brother out of these machines .And they are realy putting the hours on them around here 575 hours in the first 7 weeks on the first one alone. We have also tryed Newholland and Case these two are the same machine made under the same roof and hard on fuel.Come to think about it I havent ran my old dozers for months. Digitup.

i used a case 450 c to dig my pond, its pretty good sized pond too, about 350 feet in diameter and 9 feet deep at the deepest. well, i used an excavator too. anyway, the case was my old bosses machine and i sure didnt have a bit of trouble with it, except trying to get used to the foot steering. had a harder time getting used to the excavator with the joysticks, i`m used to the old 5 lever machines. guess most all machines i`ve used are mostly old machines. even used to use a dragline to load a dumptruck. wish i had that old dragline around yet to dreg out the pond now. heck i just need a D8 or a 850 Deere! pull the plug on the pond and start digging! would love to get around 20 feet deep and have my own fishin hole! hey digitup how close to international falls mn. are you? maybe you could be my new best friend with those new 550`s

i`ll take a look at the pic`s but my keyboard will get soggy from Drooling!

They are nice to run but wont last as long as the old Deeres I am afraid and as the Canadian and American dollar are worth near the same the list price is around $107000.00 with most toys this is a far cry from $14700.00 for dads first 450 new If you look on a map I work between centeral lake huron and east to centeral lake Ontario a good days drive from you but help your self I would find the neighbour dealer and get one delivered to your sand box my self.Digitup.
