Max 25 - multiple questions

BlackOps · Feb 27, 2025

Ok - i am still screwed trying to get my tractor to start. dealer is 50 miles away and has been useless after many attempts to get help.

so - and please no lectures and be patient - i do not now that much - i have no serious metric tools and i am trying to attempt to get this woking myself. other than that i may have to try to get the local john deere dealer to fix this if they want to or can...

first - is the starter the unit that the solenoid screws into or is connected to? how easy is it to replace? do you need any extra gaskets, screws/bolts etc besides the atual starter unit to replace. what metric tool sizes are needed?

how easy is it to replace the 3 glowplugs? again what size sockets or wrenches are required?

i knew there was maybe another couple of questions i was going to post last night before i went to sleep but just needed to sleep and post this sruff this morning... so i may ask more later. need to go out and cultivate and get some stuff planted.

oh any diagrams of parts locations and instruuctions would be greatly appreciated. and again, be patient with an old sick man with a knows enough to be dangerous amount of knowledge re: tractors and engines etc.

thank you all!

you would be much better off telling people "how" it doesn't start. changing a million parts is just a waste of time for everyone

First - what are the symptoms, and when did you last start or run the tractor? First is to start with the battery and power aspects.

With the key on do you have dash lights or any indication of power? If you have power, take a meter and check the voltage - should be 12.6V or so. Does the glow plug light work? If all these things work, and still no start, it could be a safety switch - seat, clutch, PTO etc.

As far as tools, you can go to any harbor freight, tractor supply and get a 10$ volt meter, and a set of metric and sae wrenches for under 20$.

One of the most common no starts with this series (Mahindra MAX) is the electrical connection to the glow plugs. Removed the connector, stripped the wire back as needed, replaced and crimped a new terminal connector on 3 of this series.
Next is making sure the PTO levers are in the proper position for the safety circuitry to allow current to the rest of the starting system.
As @Carl_NH mentions, check those items.

Note, that the glow plug light works properly when the electrical connector is bad to the glow plugs.
