Hi and welcome to TBN. More importantly, thank you for your service to your country! God bless you and all who have served, do serve and will serve.

Intermittent issues can be difficult to diagnose, but the good news is that 9 times out of 10, it's a simple fix.

Start with the obvious (Loose wires, poor connections), then test the safety switches. Also check the ignition switch. I seem to remember reading that some models had issues with their ignition switch and water (?).

Good luck and let us know how you solved your problem.

You need a helper. One person on the seat, making an attempt to crank the engine, the other person reading the volt meter. start by placing the leads directly on the battery terminals. Have the helper attempt to crank the engine, read the battery voltage with this load on the battery. If this appears correct, move the leads out to the battery terminal clamps and read it there. This will determine if the clamps have a high resistance connection to the terminals. Move on out to the starter bolt and frame of the tractor and repeat attempt to crank. This will show if there is a high resistance (corrosion) in the battery cables. Lets end there for now, and report back.

At73 years of age I wanted to see if it felt any better to refer to myself as a newbie. It doesn't. Anyhow, I am 73, I would have been 74 but I was sick a year. I have a 2014 Mahindra 4025 4WD and I have a love hate relationship with it. When it starts, which is rarely, I can get my work done in no time. But, many times I go out to get some work done here on the farm and it just won't start. Doesn't click or anything. So, I call myself Mahindraweary (My name is JC Cooper). I had a Ford 3000 for 40+ years and I didn't have as much trouble with it as I've had with this New Mahindra in just 18 months.

Glad to be here and looking forward to learning something. But hurry, I don't have long left.

JC, you are funny with words. When you get your tractor fixed, you need to stick around here. You will chase this down and fix it. The 4025 is a simple and reliable machine. You must either have a bad connection or a bad safety switch. If neither, then maybe a ignition switch or a problem at the starter, but that is unlikely. Seems you are getting good advice. Best of luck.

The tough electrical problems are the occasional intermittent type. Seems yours has passed that point and that actually makes it easier to chase down.

Dave is there any way you can post the electrical schematic for his tractor? I don't have one.

I don't have a handy way to do that. it's a pretty simple system.

Well, is there the typical start relay and is it wired from the key thru the various safety switches that controls the current for the starter solenoid?

Others have pointed to a battery and starter or cable problem but I'll bet dollars to doughnut holes it's one of the so called safety switches. If you have a shuttle drive, give the shuttle shifter a jiggle because that switch is often out of kilter, mine was. Also check the switch under the seat and the PTO switch. If you ask me there are too many of those damned lawyer switches on tractors today. If you're too stupid to operate a tractor you're gonna kill or maim yourself and no switch is gonna prevent that. It may put it off a while but it ain't gonna prevent it.

pull the pto lever back.. remove the brass cover over the pto switch.. then push the lever back forward first to be sure its hitting the switch. if so then press it in manually and see if it clicks...

 

[Navasot]

the one on the high/low just screws into the side of the shifter housing its very easy to get out..

One simple way to help determine if it is likely safety switch or start relay problems is turn on the tractors headlights. Now observe these lights carefully as the assistant attempts to start the tractor. If the lights dim a bunch or even go out, then the corroded cable, corroded connections or just defective battery are likely culprits. If the lights stay near full brightness as the tractor is attempted to crank, then it is not likely a battery/cable/connector problem and much more likely is the key switch or one of the many safety switches in series with the coil of the start relay or the start relay itself being defective.
