Replacement for an obsolete gearbox
We needed this gearbox as a replacement for an obsolete model made by Grove Gear back in the 90's. Needed to call the company to find out the equivalent and they directed me towards MRO. If this one will last as long as its predecessor I'll be retired by the time it will need to be replaced again.
