It covers engine oil and filter change, front axle oil fill and bleeding process, air filter replacement with grease points, hydrostatic fluid fill and cycling, fuel filter swap, and bleeding air from fuel lines before restart. Useful for owners doing their own scheduled maintenance and wanting step-by-step visual confirmation, including mistakes and workarounds.
Posted by the RP SR channel, an owner performing DIY maintenance on their own tractor rather than a dealer or professional mechanic.
The tractor takes about 4 quarts of 5W-40 oil, and the owner used Bad Boy Tractors bulk 5W-40 for the change.
The oil filter nut takes a 17mm socket with a 3/8 drive to loosen and tighten it.
Open the bleed screws one at a time and let diesel run until bubbles stop, then repeat both again to make sure all air is out before starting.
The owner's tractor took about 3 and 1/4 gallons, checking the dipstick as he went since it can vary if hydraulics fully drained.
