My guess with that many hours on it that the VGT turbo or actuator should have been replaced. EGR valve should have been changed or deleted. Injectors may have been replaced.

 

I would want to see some maintience records first so you can see what all has been replaced. How many hours a year are you going to be using it? You might be better off with a smaller but newer sprayer with less hours.

 

Drive it till it is running warm. Make sure the hydro stat keeps full power to the wheels and is not worn out. Takes a few miles in a field to usually do this on a summer day. Having to rebuild a drive system from a blown drive motor gets a bit expensive and time consuming.
I love oil samples. Do oil samples on each compartment, engine, hydraulics, what ever, then send in for testing.

 

Hi guys. I'm going to go have a look at it tomorrow, it's at a dealership so driving it about will be pretty limited but hopefully they should have some maintenance history on it as well. I'm not sure what the situation is yet but there should be some sort of warranty period with it, it's always a lucky dip buying second hand machines lol. Obviously the hydro and engine are pretty hard to inspect visually ill do my best. I guess what I'm really trying to find out is what I can visually inspect to get an idea on maintenance and how hard of a life it has had, form some sort of condition report for myself. There must be things that wear out or break etc that I can look for? It will be the first one I've looked at so I'm not familiar with these at all.

Crtoney, I haven't seen it yet but I didn't think these would have had egr etc on them, it might have though. My 8310rt is only tier2 (Aus) so I'm not sure, hopefully not lol.

Duchek, not sure how many hours we usually do but we crop 5000ac which can add up to about 20000ac of spraying each year. I don't want to go any smaller than one of these, I'd rather something with a 15000l tank lol. I'd like something newer but it would have to be a pull type and that brings other issues, working on 3m ctf. I don't have the coin for a new tractor to go with it and I dont really wanna spray that much in a 7080 allis lol.

 

Neily I have 4930 with 3800hrs which a bought with 2000hrs. Is the machine at Dubbo?

 

One thing to check is how many acres it has done. That will let you know how many of those hours were spraying and how many were idling/roading. 7000 hours is peanuts for a diesel engine so I wouldn't be concerned there. Getting service records would be a big plus. The only REAL concern would be the hydro pump. While they seem to have a good reputation (haven't heard of any failing) if it DOES fail, you have a MAJOR problem as it will contaminate the entire hydraulic system (which is pretty much everything on the machine) and the machine would likely be a write off. Wheel motors also have a good reputation but if one fails, any filings would go directly to the hydraulic tank via the return line and there are 3 filter screens screening out all oil as it leaves the tank so the risk of total contamination is less. Otherwise, if the price is right any failures would be just fix when fail and go. Being from a dealer, you may try to negotiate a price that includes a new hydro pump installed and some warranty that includes the right to return it if it turns out to have hydraulic gremlins indicating that is has had a hydro failure and the system is contaminated. It's unlikely but that it is but........PYA. Those machine are also famous for hydraulic hose failures due to rubbing but is easily mitigated. Look the hoses over carefully for rub locations.

 

Another thing. If you find problems, ask for them to be repaired. Dealers ask higher prices because they usually sell a machine with repairs done unless stated. At least any good dealer. Selling junk haunts a dealer for ever, they don't want that. Mention that to the dealer and do as licensed to kill mentioned. Good advice.

 

Hydraulics will be the area that is most likely to cause you concern. Try and find out if the wheel motors have been worked on. They are approx $16500au each out of Deere. Can be reco-ed at Toowoomba though. Oil needs to be changed in wheel motors at the same interval as engine oil. As already mentioned, check hoses for rubbing. At those hours hopefully the previous owner has sorted those sort of problems.

Would also find out how long solution pump has been on it. If it's like our 4940 it will only have a cast housing and they don't last too long. Deere don't offer a stainless pump although Sprayerbarn can set one up as an aftermarket option. Our 4730s do have stainless pumps out of JD, so don't know why they didn't put them on the 4940.

Booms are pretty good. Won't be hard to tell whether it needs any attention or not.

Shouldn't need to worry about the engine at those hrs. With regular maintainence should have plenty of life in it. We work on between 0.8 - 1L/ha of fuel to give you a rough guide of fuel consumption.

I assume you are referring to the planetaries as the wheel motors run on the same hydraulic oil as the rest of the hydro system (which should be changed at 500 hour intervals). The planetaries are an independent unit that run 85-140 synthetic and should be changed every 250 hours with the engine oil.

 

Hi all,
Ausmac yeah it's the one at Dubbo, pretty sure it came from warren. Do you know anything about it?

I had a look at it today, doesn't look tooo.... bad. Certainly plenty of things that need doin to tidy it up but nothing major I guess, a lot of little things but they all add up.
I can see what everyone says about rubbing hoses! I haven't had a look at any others so I don't really have anything to compare it to either, Condition or prise wise.
The booms would be the worst part of it visually that I can see, had a lot of repairs and one has a twist in it. Loose,broken brackets for the hoses,kinked hoses. The more I think about it the more it sounds like a project. More time than expense though I'd hope. I suppose the big $$$ items are the Hyd system and that's going to be unknown.
Can't believe how expensive auto steer is, I already have rtk but really 20k for a receiver and a few activations!

 

It Is from Warren. I think chesterfield should have all the repair records. It's a farmer machine and pretty sure they everything that had to be done was done. I did a similar thing what your doing a few years ago and went from a trailing boom to SP and looked at few 4930s and got 2000hr machine but I paid over 200 for it. I think I have put 50000ha and 1800 engine hours. The top half of a 4930 is a 30 series tractor. So not much has gone wrong. A few codes, the seat ****ting itself , the turbo actuator had to be done but that's stuff that happens to the life of a tractor. Hoses rub and blow but the all the hoses that went on me were original JD hoses not a common problem. I put pig tail spiral wrap on all the wheel motor hoses and haven't had any dramas. Never had any solution pump dramas. Had an airbag blow from mud working a hole in it. Don't buy a new one form JD you can get them a third of the price. I don't think you going to have any problem with the hydraulic side of that machine. If the tyres a good and its paddock ready and you knock a bit off the price then I would probably buy it. They can drive you insane but they are awesome to drive and you will never go back to a tractor!

 

Speaking of JD airbags....has anybody found another source for them. The ones on the sprayer are over $1000 and the small ones on a 615 pickup are $500 to $600.

 

I bought an air bag for my 4830 from the local truck shop. It was still more money than a truck one but way cheaper than Deere. All they needed was the measurements to match it up. I haven't changed mine yet, will do it in the spring. Mine hasn't failed yet but is chaffing around the bottom where it rides when deflated. Will use a belt sander to soften the edge of the pedestal when I get the old one off. Maybe something for guys to check.

 

On the bigger Deere’s the mud collects on the bottom of the bag where it rolls over itself and it rubs a hole through eventually.

 

That's exactly what happens. If any mud gets around that airbag it needs to be cleaned off as soon as possible. If it sets hard you get a hole real quick. On our 4730s the airbags are up higher and we never have trouble with them.

 

Ausmac, 3/4 tyres are good one is odd and looks a bit rough. I'm still interested in it but it's a ways of being paddock ready to me. There gonna have to knock the price down for me to buy it. I'm gonna go have a look at another one on Saturday with 5000hrs on it, its dearer but will give me a bit better idea of what I'm looking at. I'll compare the two and go from there.

 

Hey there.
So I had a look at another 4930 yesterday, overall it looks pretty tidy apart from oil leaks. A couple of the wheel motors are leaking a little from behind the black plastic cover and one appears to be leaking/weaping from the hub seal. Ok so I realise these are the big cost areas here but how serious a problem do you guys think this is, I guess it's hard to know but could we just be talking seals and hose leaks or rebuilding finals what's the general rule on these?
Generally this machine is tidy otherwise, boom has only one or two repairs that I saw vs probably 50 on the other machine which was its weak point. The boom on the other is a wreck in comparison.
Has a new turbo, new egr valve, new starter motor and a ss hypro as well. Apart from the oil leaks it seems to have had most trouble areas covered. At this point it's looking like the one I would buy, can I buy parts for wheel motors and planetarys and rebuild myself? What sort of hours can one expect to get out of the wheel drives, are they a worn out at 5000hr deal or should last a long time assuming proper maintenance?

 

I would take the plastic covers off and have a look. Could be a hose at the connection or something and, if you buy the machine, throw those covers in the shed and leave them there. The planetary leaking at the outer seal may, or may not be a problem. There is an O-ring for that outer cover but the only time I had one leak there it was because the inner seal had failed and the planetary was filling with oil from the hydraulics (wheel motor). That inner seal is pretty much fool proof and can only fail if the planetary is failing. If that planetary is over full, it is likely done. Bear in mind, everything I have stated is from my experience with a 4830. There may be some inconsistencies with the 4930.

 

Not sure on cost for the hubs for the 4930. They aren't cheap for the 4730. I wouldn't plan on rebuilding. You need some special tools and even then they are very easy to screw up. Best is to just swap out for a rebuilt one. It's not a big job, at least on a 4730, to change the hub out. I swapped mine because it was seeping at the end of the season last year.

 

Well I took the punt, should turn up in a few days. Wish me luck ��

 

You bought the one from Dubbo?

 

No the one from Narrabri. Better value I thought, Still needs a few things fixed but hopefully will be a good machine.

 

Hi ausmac, that 4930 at Dubbo sold for 75k at Ritchie brothers today. Funny how the dealer couldn't possibly go any lower than 100 when I looked at it lol.

So got my spray home now, haven't put any water through it yet though. Can't see any real issues with it yet, few oil leaks but guessing that's going to be a continued problem with so many hoses.
What's the story with the 2630, seems as though it's a bit limited with operating info. How does one get a decent "dash" or is it a bit basic? How come these machines don't have a decent readout on the corner post like my 8310, doesn't even have a decent fuel gauge or anything, rpm speed etc. maybe I'm not doing something properly?
Also does anyone have any ideas on good online supplies for nozzles and caps or are the local dealers as good as any place to buy em?

you probably wouldn't be first to complain about that - 4940s went back to having that data on cab post. there are lots of ways to custom configure a 2630 and once you catch on its pretty easy but id definitely get the dealer to set it up first time.....


Unless it was set up with some aftermarket stuff "JD" nozzles are just Hypro, but the nozzle body is TeeJet compatible so lots of options to go with nozzle of choice. personally I was happy with the hypro though after having Air bubble jets on last spryer, these plugged way less. Not sure about in Aus, but here they can be found a little cheaper from some other suppliers but really only would make a big difference if doing a whole set. Hypro makes a little plastic wrench that is well worth the investment they use a way thicker O ring and twist on much tighter than most nozzles. if sprayer has the HiFlo option the nozzle bodies from the dealer are atrocious.

 

I think it was traded in at 60k its still a very cheap. I have a few 2630s and have run them for years. You can set up the layout however you want. There not basic, you can customise the layout of the home page add cameras etc. Before my JD I ran one in my Hayes tag along, its a good controller once you get used to it. My advice other than the usual wheel motor horror stories is to put spiral pig tail wrap around wheel motor hoses and return lines to stop rubbing. I would check and replace hydraulic hoses to the boom tilt as I had an original one bust at 3200hrs and one side of the boom hit the ground it was on a headland going slow but it could of been a total boom write off at speed, I put taps to slow the fold speed of the boom to stop everything from smashing to bits, the other thing I is blowing o rings in hydraulic blocks near the spray pump. I just replaced many a I could and don't have any dramas.

They are a complicated animal but if you go hard on the maintenance they can smash the acres and be awesome to drive. Next week my tank and mates 4940 tank is going to Horsham hydraulics to be extended to 6000litres which is going to be awesome.

 

Ausmac
yeah I'd say it was good value at that price as well, shame the dealer was so greedy. I'm pretty happy with the one I bought though in comparison. I've got the screen sorted now still think I would prefer the corner post deal like my tractor though. It's got quite a bit of pig tail on it already I'll have a good look and see if I need anymore in spots, there is a few oil leaks around the hypro motor needs a good wash so I can find them. I like the tap idea on the wing tips, it's fairly violent when it folds in and out.
I checked the oil in the planetarys the other day and they were spotless so that was a relief!
How do you think it will handle the extra weight in the long run? How do you fill your spray? I'm thinking about setting up a trailer with everything on it and just pumping it all in. The hopper on mine is that small it's useless I think, too small to wash out a 20l drum and I won't need the machine running either.
How important is the hi/low rate tap on the back, mine has been removed I think. Usually use 50lha up to 100, does it matter?

Brad, yeah mine has the 5 nozzle holders, thinking about buying 3 new sets of nozzles and caps so it runs into a fair bit of coin. Have managed to get onto a pretty good deal on some teejet Ai stuff so I'll be right for a while.

 

I ended up with a 4930 that has 3120 hours on it for 64,000 USD this winter at auction. Farmer owned machine doesn't have any frame rust so that is nice. Going to set a new leader box on it and hope for the best. I figure if I replace all 4 planetaries thats 40k or puts my price up to 104k. Should have a lot of life left in it at 3100 hours. Probably wont put much more than 60 hours a year on it as you can get so much done with those things and a box.

 

Vailcat its sounds like a great buy. If you do 60hrs a year nothing will go wrong. I'm back on acres to 30 thousand a year but before our farm split up it 60 thousand. Neily took the tank off today I'm taking two tanks to Horsham which is 950 kms. As far as weight is concerned if its very wet it will turn a pig into a very fat pig. The rig wil handle it as liquid fert is very heavy. The reason for going all the way to Horsham is the cut and weld hundreds a tank and are authorised to do Case JD Rogator from new with factory warranty. The yanks don't are happy with a 1200 gallon tank or 4500l which is Australia is useless.
