For someone considering a John Deere 624K, if the machine has been properly maintained, it’s a very strong player in the mid-size loader class. The engine pulls well, the hydraulics are quick, the cab is comfortable, and the resale market is active, so it’s a relatively low-risk investment. The risk side shows up when maintenance has been neglected: the first problem area is usually the transmission (especially weak pushing power in 1st gear and slipping when the oil is hot), followed by hydraulic leaks and Tier 4 emissions issues related to the DPF/EGR system; on units where the engine has been opened or replaced, electrical and solenoid faults tend to appear more often. That’s why, with this model, instead of chasing “cheap hours / cheap price,” you should focus on dealer-serviced machines with solid service history and thoroughly checked transmission, hydraulics, and emissions. In short: if you find a 624K with transparent history and regular maintenance, you’re buying a productive loader you can rely on for years; if you buy one with unclear maintenance and a tampered engine/transmission, there’s a high chance you’ll give back your savings in a short time through transmission, DPF, and hydraulic repairs.
