One thing that often causes trouble is trying to run a diesel in cold temps on fuel which had been purchased in warm weather. I see Hedley at -8C which could cause fuel gelling. Remove it and polish the cable end and the spot where if touches the frame. You can jump the starter following this...

After years of coping with a 2WD Nuffield 465 I learned the critical aspect of tensioning tire chains is not to go from one side of the wheel to the other but rather get a metal circle from places like TSC. I think they are used with horse harness stuff. By pulling each part of the chain towards...

I bought my M7040 in 2012 with cab and loader for less than $40,000 Canadian Now the same tractor has not depreciated but appreciated in value. Rather than trying to flog your existing machine check the economics on getting a bigger machine. I recently bought a 2018 KX040-4 excavator knowing...

I have info for the TG1860 which looks very similar but with dual disks. The coupling is made by Weasler in USA. Their web site may lead you to an alternative supplier other than your Kubota Dealer. Weasler My friend was experiencing a lot of vibration and as we dug into it we found the dual...

Further to my earlier post. Does the glow plug indicator on the dash come on for a brief time and then go out? Are there any error messages on your dash? Your tractor is a sophisticated one with electronic common rail fuel system. An electric pump provides pressure to a pipe serving all...

You also need to You also need to try jumping the trigger wire to the starter solenoid. This is bypassing every safety feature built into your machine and you can run yourself over or end up with a run-a-way tractor. Best to have someone in the seat with foot hard on brake. Dave

Everyone will tell you that using starting fluid will destroy your engine. I see you are in California but what temps are you coping with. Glow plugs not working would be my first guess if engine damage has not already happened with bent connecting rods lowering engine compression below what is...

Could you please clarify which model of M7950 you have. Please edit your profile so I can understand where you live. The initials Mi are not clear to me as a Canadian. A complete loss of fluid would make the system free wheeling as the control valve could have nothing to work with as a GEROTOR...

From memory the basics of this engine run-a-way recall involved first the crankcase vent system freezing up due to moisture accumulating and freezing in the vent tube which on modern engines is directing blow by back into the intake. Once ice has blocked the vent tube, leakage by the piston...

First remove the cable from the instrument and run the engine to see if the cable inside is rotating. If it is then connect the cable back to the tach and connect a drill to the far end of the cable to see if you can make the tach needle move. If all else fails look for an automotive...

Ontario Canada has been having very cold conditions in some places. Problems with cables freezing due to moisture inside has been a recurring issue with my M7040 rear remotes. I removed one piece of interior trim to allow cab heat to get to the remote cables. Tell us about where your tractor is...

The checking out AC output from all three dynamo wires need to be done with the dynamo disconnected. The pair feeding the headlights may or likely will be a lower AC value because it is output to simple light bulbs. The pair feeding the rectifier will be the higher value found in WSM. Testing to...

Perhaps your problem is not with the front axle shaft but rather the mid pto shaft going to a front mounted implement. The shaft looks small like a mid pto shaft. Without something connected to the front end of the shaft there may be a U joint banging against something. Dave

Please advise on type of transmission, Manual or HST. Is 4WD completely engaged. That shaft should only be turning when 4WD is engaged and tractor moving. If this rotation and noise is when the tractor is stationary, we need to know This forum has a number of members with B7100 who will get...

Are the labels on your tractor in English or Japanese? Where did you get the B7001. Please provide the full serial number likely on the side of the transmission. I ask these questions because you may have a tractor only made for the Japanese market and imported into North America outside normal...

By chance do you have a multimeter and know how to use it. When you jump from your truck to the starter where do you connect the ground connection? If you read the attached file you will quickly see that voltage drop throughout the system supplying the starter is almost always the problem. If...

What your photos show is that the battery ground connection is not one cable but two. Battery to frame and then frame to engine. Lots of places for a poor connection. They can be tight but rusty or painted thus inhibiting the electrical connection. I would still like to see the top of your...

Send us a photo of the top of your battery and also where the battery ground connects to the tractor frame/body. You have a high resistance connection somewhere. I would first remove the battery ground from the frame and really clean it. Here is an example from another members tractor. When...

Suggest you take a moment and read this earlier thread on tire hop. John Deere has done a lot of research on the topic. Tire hop It boils down to a resonant flexing of the tire sidewalls under certain conditions. Dave
