When I worked with the John Deere 310G backhoe, I found the engine power to be adequate for everyday excavation and farm work, and it didn’t hold me back on digging or loading. The hydraulic system does the JD 310G’s job under normal use, but due to the machine’s age, I ran into typical wear issues like leaks from hoses and cylinders and play in the boom and bucket. On a well-maintained machine, the forward/reverse shuttle shifts smoothly, but when oil and filters were neglected, I did experience harsh shifting and occasional slipping out of gear. Units with a mechanical injection system were relatively trouble-free, while the versions with an electronic pump and ECU required chasing sensor faults, error codes, and air leaks on the fuel side, which drove costs up. On the electrical side, I occasionally had no-start issues even though the starter turned and random warning lights from typical contact/corrosion problems. Overall, a properly maintained 310G got the job done and didn’t leave me stranded, but based on my experience, it’s crucial to inspect hydraulic leaks, rear axle oil condition, injection/ECU health, and the electrical system carefully before buying.
