I am an attorney and I represent a farmer in Nebraska who had a combine fire 2 years ago using the 9500. The combine didn't burn up but his field did as well as several others. Now, he is getting sued.

Does anybody have any information on whether the 9500 JD Combine is one that likely starts on fire or starts the field on fire. Or, any other information would be appreciated.

I'm trying to defend my client-farmer and need some help.

Thanks.

Of the 50 or so 9000, 9010 and 50 series combines our dealership has sold since 1989, we have not had 1 burn up. However there are 3 areas where the chaff has been charred where a fire could have easily progressed. One is the reel drive pump bearings as Chris said. Second, we have had a few bearings in the upper variable speed feeder house drive sheave go out causing the chaff and straw that collects behind the sheave to smolder. and last, a few park brake cables have stuck causing the chaff that collects on top of the transmission to smolder. I have heard of the chaff collecting up around the exhuast manifold and catching fire as G-MAN talked about but haven't experienced that in our area.

I am an insurance agent in nc and a small-time wheat farmer. I have a client with a 9500 JD that has caught on fire two years in a row. Turns out it was a defective cylinder that flexed enough to hit the rasp bars or whatever they run close to aand set the straw and chaff on fire as it was leaving the cylinder. Damage to the combine was minoras the fire dept. spent the night with the combine two or three times. The cylinder has been totally replaced,and I haven't heard of any more fires with this machine.

Karl, sounds like nobody has ever checked the cylinder stop on this machine. There are tools and a procedure from Deere that set the clearance between the cylinder and the concave. Then once this is done you set the stop so that there are no or should be no problems like this. Also if they were hitting/rubbing your client should have heard this in the cab. I recommend your client has his combine in for an annual inspection, so that little things like this don't turn into big ones. One thing to tell your client is to run his concave open and shut at the end of everyday to clear trash off of the cylinder and this keeps the concave movable since if it sits in the same setting they get stuck. Also emptying the stone trap everyday helps alot too. Trust me, seen this many times. chris in Nebraska

the owner has run jd combines for 30-40 yrs in wheat, corn and soybeans, so i'm sure he knows how to set the clearances correctly. the problem was a flexing of the cylinder that allowed it to contact the concave. the cylinder was not welded together strong enough. the cylinder has been replaced with no further problems.

Where did the fire start on the combine? Read your post yesterday and thought of a neighbor with new 95 series- two fires within a few days. Problem was a plastic sleeve over a rotating shaft, probably below, or to the rear of the cab. Crawled inside to ID it (ran into him today and asked him about it). JD has a correction- involves some other material and some stainless clamps or u-bolts? Contact me if you'd like to contact him. Now, lawyer jokes aside, our youngest daughter is headed to Stanford next month and wants to be a lawyer and work for the FBI. Don't know where we went wrong!!!Darn proud of her tho-.

I worked for a John Deere dealership in Humphrey Ne. during 1995-99, and we had a few fires around the exhaust manifold like G-MAN said, also the new machines in 1998 had a problem with the bearings on the reel drive hyd. pump behind the wheel on the ladder side of the cab. The factory forgot to put grease in the cavity or used the wrong style bearing in that application, but there was a update/recall and on the seven or so combines half of the bearings got hot enough to melt the plastic plug that kept the dirt out and 1 or 2 started the chaff on fire, but luckily just smoldered and went out. Most of the fires I think are just neglegence on the operator for not keeping their machines cleaned off. The salvage yard in Madison Ne. has a 9510 Maximizer that an engine fire and it didn't take them long to get rid of the cab so was their a cab fire someplace else in the country that someone needed a cab that soon? Who knows. But if his 9500 started the fire, doesn't his insurance cover this, and if he didn't have insurance good luck trying to win his trial. And if you do win this you'd better advertise more cause you'll find alot more clients out here. p.s. His combine didn't burn up but was there anything found that could have caused it, other than a hot ember from the muffler? please email back any comments thanks chris in Stanton Nebraska

Excellent comment on the reel drive pump. A lot of our customers don't even know there's a grease fitting back there, so we end up replacing a lot of those bearings. By the way, I work at the JD dealer in York.

I'm a tech at a JD dealership that has a lot of 9000 combines out, so maybe I can help. Is the 9500 an inherent fire starter? No. Can they start on fire if improperly maintained or cleaned? Yes, Chaff and dirt can build up on top of the exhaust manifold and start fires, but those are usually contained in the engine compartment. Bearings running dry and getting hot can also start fires very easily in any color combine, baler etc. Occasionally, rodents will chew up the wiring and this can lead to shorts and fires, also. I'm not a lawyer, but I would think that they would have to prove that it was negligence on your client's part to be able to collect. Is that correct? We usually have a couple good combine fires on JDs per year out of several dozen machines that we work on, but they normally don't result in the entire machine burning up. Talk to a dealer of any other color of combine, and I'm sure you will hear much the same story. By the way, where are you located in Nebraska? I live in Nebraska myself.
