Which wire needs to run to the battery to charge
Being unfamiliar with mowers, the battery seems accessible. So there is no need for having a socket or appoint other ways.
Trickle chargers have both cables, one with small clamps for the terminals and one permanent pigtail cable. The cable with plug that can be installed is always bolted onto the terminals.
Ground wires should be a distinct green/yellow color and the main negative is a thick one that just bolts onto engine or frame. A test will then find 12 Volt wires of those that are life when the engine is switched off. I don't have high hopes of those being many and charge is performed at maximum of 1/10 the battery Amp at most, usually it is much less like hundreds of Milliamp?re. Especially when a full charge is being reached. Also for metering the Voltage a battery installed cable is the right choice. It determines charge on tenth of a Volt. 12 Volt batteries are close to being depleted and 12,8 up to 13,2 Volt are full. Charging with the engine running would show 14,2 Volt on a motorcycle.

My John Deere f725 starts up but the blade won't engage
Check fuses, see attached pic. If fuses are intact then further troubleshooting is required. Check the PTO switch connector is properly attached and not burnt or melted (common failure in older machines).Same for the electric clutch connector.You can make an audible test of the PTO clutch with key ON engine OFF. Turn ignition switch to run position but do not start the engine, then move the PTO switch ON. The clutch should make an audible pop sound.If no sound then use an automotive style test lamp or a DMM to check for power at the clutch.If power (batt +) and ground (batt-) at the clutch, then disconnect the connector at the clutch and measure resistance of the clutch winding. Typical resistance is 2-4 ohms. If it reads 0 ohms, reverse leads and re-measure. If it reads open (infinity) then likely clutch winding has failed or wire has broken.

John Deere GX85 won't restart after shutdown
I assume the starter is dead after it's sat a few minutes, that's what your talking about when you say it won't turn over. If this is the case use a test light or multimeter at the starter hot (red) lead, see if power is getting to it, if it is the starter has issues, if not ,start tracing back from the starter to the safety switches all the way back to the key to figure out where the issue is, this should be very easy to diagnose.

John Deere Backhoe loader Mod. 210C. Can I replace EATON- Vickers Van Pump instead to Double stage Gear pump SAUER or VICKERS?
Replacing hydraulic components in heavy equipment like the John Deere Backhoe Loader Model 210C requires careful consideration, as it can impact the machine's performance, safety, and warranty. Here are some important factors to keep in mind when considering a pump replacement:
1. **Compatibility:** Hydraulic pumps are designed for specific systems and applications. The replacement pump must have compatible specifications, flow rates, pressures, and connections to work effectively within your machine's hydraulic system.
2. **System Design:** The hydraulic system of your backhoe loader is designed with specific components that work together. Replacing a pump can potentially disrupt the balance and efficiency of the system.
3. **Flow and Pressure Requirements:** Ensure that the replacement pump can provide the required flow and pressure needed by both the main and steering hydraulic systems. Mismatched flow rates and pressures can lead to performance issues and damage.
4. **Relief Valve and Safety:** Hydraulic systems include relief valves to prevent overpressure. If you're considering a pump replacement, you must ensure that the relief valve settings are appropriate for the new pump's specifications.
5. **Mounting and Connections:** The new pump should have compatible mounting and connection points with your backhoe loader's existing hydraulic system. Modifications might be needed to ensure a proper fit.
6. **Manufacturer Recommendations:** Consult the manufacturer's documentation, technical manuals, and guidelines for pump replacements. They may provide insights into compatible replacements and installation procedures.
7. **Professional Assistance:** Given the complexity of hydraulic systems and the potential impact of pump replacements, it's advisable to consult with a qualified hydraulic engineer or technician. They can assess your specific situation, recommend suitable replacement options, and ensure proper installation.
8. **Warranty and Support:** Keep in mind that modifications or replacements not recommended by the manufacturer could void warranties and complicate maintenance and support in the future.
9. **Testing and Calibration:** After any pump replacement, thorough testing and calibration are essential to ensure the hydraulic system operates safely and efficiently.
Remember that modifying heavy equipment like a backhoe loader requires expertise and knowledge in hydraulic systems. Any modifications should be carried out by professionals who are experienced in working with such equipment. It's recommended to involve the manufacturer or authorized service providers to ensure that any modifications are done correctly and safely.

John Deere 755. After start up continue to hear a clicking/buzzing, new glow plugs, controller relay seems fine, sound is near the glow plugs 755 JD new glow plugs new battery
Some mechanics use a stethoscope with a simple metal tube probe instead of cup to narrow down where a sound comes from.
Without actually hearing it, my first guess would be valve tap (sound comes from the cylinder head or one side of the block near the head). This could indicate an oil pressure problem, worn or sticky valve lifter, or a rocker arm that needs adjustment. If the oil is low or dirty, try adding or changing as needed.
Another possibility is a noisy fuel injector. although I've literally never heard of that. Try a fuel injector cleaner made for diesel engines.
Glow plugs aren't supposed to have moving parts to make noise. I suppose a defective plug with a poorly sealed heater element could do it, but I would think you'd have rough running and maybe see the glow plug cable vibrating unusually.

I need a wiring scemaitc for a john deere 285
A wiring schematic, also known as a wiring diagram, is a visual representation of the connections and components in an electrical or electronic system. It uses symbols and lines to show how different components are connected and how electricity flows through the system. Creating a wiring schematic involves understanding the symbols used, the layout of components, and the connections between them.
Here's a basic guide to creating a simple wiring schematic:
- Gather Information: Understand the components and connections you want to depict in the schematic. This could include items like switches, lights, motors, sensors, power sources, and more.
- Choose a Software: You can use various software tools to create wiring schematics. Some popular options include AutoCAD Electrical, Eagle, KiCad, Fritzing, and even general-purpose tools like Adobe Illustrator or Microsoft Visio.
- Start with Symbols: Learn the symbols used for different components. Common symbols include:
- Lines: Represent wires or connections.
- Circles or Dots: Indicate junctions where wires meet.
- Squares or Rectangles: Represent components.
- Lines with Arrows: Show the direction of current flow.
- Zigzag Lines: Depict resistors.
- Diagonally Arranged Lines: Indicate capacitors.
- Various Shapes for Different Components: For example, a triangle could represent a transformer.
- Layout: Place the symbols on the schematic in a logical layout, following the actual physical arrangement of components as closely as possible.
- Connect Components: Use lines to connect the symbols representing components. The lines represent the wires carrying the electrical signals between the components.
- Labeling: Label components and wires as needed to provide clarity. Use text to indicate the function or specifications of each component, as well as wire labels for identification.
- Include Notes: Add notes or annotations where necessary to explain complex connections or to provide additional information that might not be obvious from the schematic alone.
- Review and Test: Carefully review the schematic to ensure accuracy. If possible, simulate or mentally trace the connections to ensure they match the intended functionality.
- Finalize and Share: Once you're satisfied with the schematic, save it in an appropriate format and share it with others who might need to understand or work with the system.
Remember, creating accurate and effective wiring schematics requires a good understanding of electrical principles and the specific components you're working with. If you're not confident in your abilities, it's a good idea to seek assistance from someone with experience in electrical engineering or electronics.
