Gear Oil for Leinbach post hole digger

[wuzup45]

What is the best gear oil to use in the L7200Jr? Does anybody have any suggestions about its use. I have heavy clay soil here in Georgia. Thanks, Barb

As the gear head is a slow speed application I would use a EP 90. It is the most common gear oil.

Any 90 weight gear oil including multiviscocity so long as it includes 90W
