Hello All,
What type and weight of Hydraulic oil should we use in topping off a model 44 unit. It's mounted on D4/7U serial#15195. Thanks for your kind help and hope you all have a great and safe 4th of July.

If your topping off you should match whats in there.
Original spec is SAE10 engine oil.
ISO 32 would be an equivalent hydraulic oil.

If the pump is tuckered you can use SAE20 or ISO 42 but it may be a bit sluggish until it warms up.
