Read articles →This is a real owner performing the 100-hour service on their own JD 3025D, following the manual's break-in schedule step by step: draining and refilling the front axle fluid, swapping the hydraulic oil filter, changing engine oil and filter, and greasing fittings, with commentary on tools, oil color/metal debris, and quantities used. Useful for owners approaching this same service milestone who want a hands-on walkthrough rather than a spec overview.
Posted by an individual owner documenting maintenance on their own tractor, not a dealer or professional mechanic.
The engine oil and filter, the transmission hydraulic oil filter, and the front axle fluid, as listed in the owner's manual break-in schedule on page 35.
It takes one gallon of low viscosity high-guard fluid, drained from three plugs, two on the sides and one in the center of the axle.
The dealer could not say exactly, but the owner figured it out to be right around two quarts lost when changing the filter.
A salesman's tip was to keep the grease gun by the fuel can and grease the fittings every time you fuel up the tractor.
