You should use the closest thing to OEM that you can (if possible).
NLGI #2 Lithium grease for the gears and zerk fitting on the secondary reduction shaft (zerk is by the right wheel) , 90W AGMA 4/5 EP gear oil in the auger gear box, the same for any metal bushings. Auger and axle bushings require no lubrication, but low viscosity lithium spray grease will help the axle stave off rust.
For sure don't go overboard with lubrication. Belts and friction disks/drive plates can be severly compromised if they get contaminated. Remove the wheels from the axles and verify there is good coverage with the Teflon anti seize from the factory. If not, apply anti-sieze (Teflon preferred) or grease to prevent seizure and assist with future servicibility.
The auger shaft on this model no longer has zerks. The rake shaft is yellow zinc plated and there is PTFE/Teflon anti-seize applied between the auger shaft and tube. Technically you could easily install a zerk with a drill, but you'd have to fill the entire rake tube with grease. This model uses a stub auger shaft much like the Simplicity models. If you feel you need to lubricate this anyway, remove the shear bolts periodically to check for seizure and spray some penetrating oil while rotating the shaft.
