M59 Hydraulic Oil Filter Change problem/question

[Spencer C]

As a point of reference, the weakest link on the M59 is the HST. It's a great machine overall, and the transmission has many nice features. However, the Grand L transmisson that's in it is running at near max capacity in the M59. Every transmisson failure we've seen on that tractor was due to extended service intervals. This is not to make you doubt the abilities of your tractor, but vigiliance with maintenance is the best course of action with the M59 HST. FYI.
