Deutz-Fahr 07

Additional Notes

• Every model in the Deutz-Fahr 07 series listed here carries a steering box fluid capacity of 0.5 liter, a figure consistent with recirculating-ball or worm-and-sector steering box designs common to agricultural tractors of the era, where the enclosed gear housing holds a relatively small volume of fluid.
• The 0.5 liter figure represents a service fill capacity, meaning the volume required to bring the steering box to its correct operating level during routine maintenance, rather than a full overhaul or system flush quantity.
• The inspection interval is specified as 12 months or 1,000 hours under normal use conditions, whichever comes first. In tractor applications, the hour-based threshold is often reached before the calendar interval due to high annual operating hours in agricultural work.
• The dual-trigger interval structure, combining a fixed calendar period with an hour meter threshold, reflects the variable nature of tractor use, where seasonal or part-time operation could otherwise delay a time-sensitive fluid check.
• All eleven models share identical capacity and interval specifications, indicating a standardized steering box assembly was used across the 07 series range despite differences in engine displacement and model designation.
• The production windows across the 07 series vary considerably by model. The D 4507 spans the full 1981-1991 range, while models such as the D 4807 and D 6807 cover only 1982-1984 and 1981-1984 respectively, representing notably shorter production periods within the same series.
• The D 3607 is the only model with a production window beginning in 1985, making it a later addition to the 07 lineup compared to the majority of models, which entered production in 1981 or 1982.
• Several models, including the D 5207, D 6207, D 6507, D 7207, and D 7807, share the same 1981-1985 production window, suggesting a concurrent phase-out of multiple variants within that portion of the series.
