When should a combine or planter be replaced? Technically, the answer is “never,” if the owner is willing to replace parts as they wear out, but there are considerations.
Modern planters with high-speed seed meters, hydraulic downforce systems and other high-tech options sometimes require a little TLC to get them ready for the field.
Folding planters often use a big, hydraulic mono-block outfitted with lots of solenoids to control hydraulic functions. Oil dripping or spurting from the vicinity of that block looks disastrous, and may be.
