Deere 435 Baler Woes

Hi all,
This doesn't really qualify to be on an "antique" equipment board, but someone here could maybe help/advise me.

We have a Deere 435 baler we bought new in 1996. It's seen very little use over the years, probably averaging about 100 bales a year. It's always baled really loose, raggy bales since we got it. It's gets really frustrating to move around loose, misshapen lumps of hay. We've tried cranking down the relieve valve at the front of the baler to tighten the bales, throwing on more twine, changing how we bale, all with only limited success.

One thing I've noticed is that the bale density/weight gauge on the front-right of the baler has never moved, it's always stayed well below the green level, even when both needles on the monitor are buried in the green and it's heavy hay. This makes me think there's air in the hydraulic system of the baler somewhere.

If anyone has thoughts/opinions/advice I'm happy to hear them. Our hay is generally thinner and grassy, but when I bale the same hay with our neighbour's old New Holland chain baler it makes better bales.
 
It could be the bale tension cylinders bypassing, a man I used to bale with had it happen to his 435 with the same symptoms you describe regarding the density guage and chamber adjustment. The good news is that it was an easy fix and fairly cheap considering John Deere parts. There is a relief valve also but I think it is easy to check and should be mentioned in your manual. TX JIM will know whats wrong if he reads your post.
 
When you close gate you charge the tension system, you should see the needle on gauge move..there is a check valve in tension block the holds pressure on it and a relief the you adjust with knob..as pressure would rise and reach the set pressure then it would relieve some pressure..there are two compression springs on each side, they will break and cause problems, just reach up and turn them, if they don't turn all the way to the top, they are broke...the tension system looses pressure when you go to open gate...the block has a piston with a plunger on it to release the pressure...if you tractor valve is leaking on that side it would not build pressure...the best thing to do is crowd those balers...they say more time the baler turns tighter the bale, might be true, but more times the baler turns the quicker you wear it out and bet there won't be very little weight difference..

There's no way a NH chain baler can make a prettier,tighter rd bale than a ""correct operating"" JD 435. Each extreme side 0f pickup attachment must be crowded to fill each side of bale. Are bales flat on top or whiskey barrel shaped????? Can you post a photo of some of the 435's bales??? If the 435 has been operated correctly & baled soft bales since it was new then I suspect that the tractors remote hyd valves are leaking internally allowing insufficent hyd pressure to be applied to tension rollers.Has baler always been pulled by the same tractor? I suggest to close gate then disconnect hoses from tractor and bale a test bale. As previously mentioned a tension cylinder can be bypassing internally or tension valve could be a fault.
 
I have 435,it makes good bales. Only my 3 year baling with it. My gauge has fluid in it. Does it just need new gauge?
