Re: Dad痴 Ford 3610 he couldn稚 tell me
The one in the front is for the transmission (check it with the dipstick shown in your picture). The plug on the rear housing is where you would fill your hydraulic fluid (the fluid is shared between the hydraulics and the rear axle housing). There is a check plug for the level of the rear housing, rather than a dip stick. I believe the plug is an internal hex (allen). It is just below the hydraulic pump, which near the back of your right foot when driving the tractor.
UTF with a 134 spec is recommended for both compartments. Do not use "regular" hydraulic fluid. 134 spec UTF is not hard to find. I just bought 20 gallons of it at TSC for around $25 per bucket on sale (Traviller brand).
