Read articles →This four-minute video exists primarily to flag one specific pitfall: don't fill the RK37 to the spec listed in the owner's manual, fill it to match what drained out. The owner explains why the spec-volume approach overfilled a neighbor's tractor and caused engine problems. He notes the same logic applies to the front axle. No step-by-step walkthrough; this is a targeted tip, best for new RK37 owners doing their first 50-hour service.
An owner-operator sharing first-hand impressions from his own 50-hour service, noting he's a general mechanic but not a tractor specialist.
Only put back the amount that actually drained out, not the manual's six quart spec, then check the dipstick to confirm the level is right.
The shop filled it to the six quart manual spec, but only about four quarts had drained out, so the engine got overfilled with oil.
The owner says probably the same thing will happen with the front axle, since it was given two gallons but only about one gallon drained out.
