John Deere 2025r Problems
We’ve seen several user complaints about the tractor’s reliability and efficiency. So, below, we explain common John Deere 2025r problems and how to fix them.
Problem #1: John Deere 2025r’s Diesel Engine Issues
The powerful 25hp liquid-cooled diesel engine is one of John Deere 2025r’s major selling points. But users often report problems with the engine.
The following are the most commonly reported issues and how to fix them;
- The engine doesnt start: If the 2025r’s engine doesn’t start, there’s a fuel intake problem. Check the starter motor, air filter element, and fuel injection nozzles and repair or replace them appropriately.
- The engine stops suddenly during operation: If the tractor’s engine stops when you’re using it, the fuel injection pump timing is off, or the fuel filter requires cleaning.
- Engine stalls when the tractor is idle: A stalling engine in idle mode is often a sign of an incorrectly set idle speed or a fuel injection pump issue. You may need to repair or replace the fuel pump.
- Overheating: If the John Deere 2025r’s engine overheats, the radiator core is clogged and needs cleaning, or the radiator cap is leaky. Otherwise, diagnose the other cooling components.
Problem #2: John Deere 2025r’s Transmissions Issues
The John Deere 2025r’s hydrostatic transmission engine uses pressurized oil to move the pistons, thus the tractor’s high efficiency.
But you may run into a few issues, including the following;
- Excessive transmission system noise: Excessive noises from John Deere 2025r’s transmission system mainly results from high transmission load or low/bad transmission oil. So, change the transmission oil or top it up. More importantly, avoid excessive load.
- Overheating transmission oil: Overheating often results from overloading or low/bad transmission oil. So, check the oil filter and avoid overloading. Additionally, ensure the tractor’s cooling system works properly.
- Backed up or leaking fluid: Backed up or leaking transmission fluid mainly results from a clogged oil drain line. First, clean the drain line, then inspect and promptly replace the seals and gaskets.
Problem #3: John Deere 2025r’s Hydraulic System Issues
John Deere gets endless plaudits for the 2025r’s powerful and efficient hydraulic system. But that doesn’t mean the hydraulic system is fault-free.
Common issues here include;
- Old or contaminated hydraulic oil: Hydraulic oil always becomes old and contaminated if the tractor has been idle for a while. Fortunately, it is easy to fix this problem. First, replace the bad oil with fresh hydraulic oil. Then bleed the hydraulic pipes to remove trapped air.
- Low oil pressure: Low hydraulic pressure is often the first sign of a low fluid level. Do you have a leak? Is the hydraulic filter element blocked/clogged? Begin by cleaning the hydraulic filter element or replace it if it’s in a bad state. Then inspect the pipes for cracks or leaks and fix them appropriately. You may have a hydraulic spool valve block if that doesn’t fix the issue.
- Damaged hydraulic pump: Sometimes, endless problems in the hydraulic system signal a worn or broken hydraulic pump. Repair or replace it appropriately.

Problem #4: John Deere 2025r’s Hitch System Issues
Most hitch issues can be traced back to the hydraulic system. Therefore, fixing common hydraulic system issues should eliminate hitch issues.
Nevertheless, you want to watch out for the following;
- The hitch raises or lowers too slowly or doesn’t move altogether: This is often due to air trapped in the hydraulic system because of old, contaminated oil. Replace the hydraulic oil and bleed the hydraulic cylinder to fix the issue.
- Is the hydraulic cylinder broken? If you notice your John Deere 2025r doesn’t build enough pressure, the hydraulic cylinder might be broken. Only a professional can repair or replace hydraulic cylinder systems.
Problem #5: John Deere 2025r’s Steering System Issues
John Deere 2025r users commonly complain about unresponsive, stiff, and “rogue” steering systems.
Here’s what you need to know;
- Non-responsive steering system: If the steering system is non-responsive, the column couple or shaft is worn. Check the couple or shaft and replace worn parts. If that doesn’t fix the issue, you may need to diagnose the steering pump and power steering control valve and repair or replace them promptly.
- Unnaturally stiff steering: If the steering is unnaturally stiff, there’s air trapped inside the system. So, bleed the system. Additionally, check the steering fluid reservoir. Does it have sufficient fluid?
- The tractor pulls in one direction: The most common cause of “rogue” steering wheels that pull in one direction is uneven tire pressure. Ensure equal pressure on all the tires to avoid this problem.
Problem #6: John Deere 2025r’s Electrical System Issues
Electrical issues are universal. Therefore, solutions for other tractors also work on the John Deer 2025r.
The following are a few issues to keep an eye out for;
- The battery doesn’t charge or hold a charge for long: Check the electrical wiring connections and clean or replace them as appropriate. For instance, replace loose connections and broken wires. Additionally, check if the battery has outlived its useful life and replace it.
- The starter turns slowly: This problem commonly arises from battery issues. Check if the connections are tight and the charge produces a spark. If it doesn’t, replace it. Otherwise, the battery might be dead and due for replacement.
Problem #7: John Deere 2025r’s Build Quality Issues
Finally, several users complain about the 2025r’s poor mechanical performance. While you cannot change or fix these concerns, you should keep them in mind when shopping for a tractor.
- Weak body: The 2025r’s poor build quality is inconsistent with Series-2 tractors. Moreover, it offers the bare minimum engine power for 2-Series tractors.
- John Deere 2025r PTO problems: John Deere 2025’s power take-off (PTO) system poses several issues. For instance, the PTO switch is faulty. It takes substantial pressure to enable the PTO switch.
- Braking issues: The 2025r’s parking brake often goes out of adjustment. Moreover, the single brake pedal and absence of an emergency brake have disappointed many users.
- Four-wheel-drive issues: It’s nice that the John Deere 2025r is a 4WD tractor. However, we aren’t impressed by the 4-wheel drive lever’s poor placement. In addition, the 4WD lever is almost on the floor, offering a poor user experience.
