This is a how-to about greasing the hard to reach drive shaft zerk on the Ventrac 4520P. This is the procedure I figured out and wanted to share with everyone since I didn't see any other videos that showed this level of detail or that work with the Kawasaki engine. This isn't an official procedure, it's just one that I worked out that seems to work. There are probably some things I left out, so use your best judgement when performing this maintenance. E.g. some things like wiping off the zerk before greasing, or re-assembling the tractor afterwards are omitted.
The 4520P has the water cooled, DFI Kawasaki engine.
This job is still difficult even with the procedure. Good luck and I hope this helps.
