What is the oil tank in front of the rad for in a john deere 3650 for?
It is a reservoir for hydraulic oil for the main hydraulic pump. Its purpose is to supply oil to the main hydraulic pump during start-up to prevent cavitation. Cavitation is caused by "vacuum" created by the main pump when it is not receiving any charge oil from the transmission pump. Without this, damage and wear will occur to the main pump due to lack of lubrication, and in time will give you weak hydraulics and then require either a complete replacement or complete overhaul of the main pump, to the tune of roughly $1000-$2000. Hope this helps!
Why won't parking brakes release on john deere 310d loader backhoe?
Your hydraulic fluid level is low, your hyd. pump is weak, your hyd. filter needs replacing, there is a spring release that is activated by hydraulic pressure under the machine, above the transaxle, if it does not receive enough hydrulic pressure, it will not release completely..

How do you replace a hydraulic pump in a john deere 4020?
Real pain. You must remove the fuel tank, radiator, and hydraulic oil cooler. There will be a plate that these items sit on that must be removed. Then disconnect the drive line coupler in front of the motor. You will need an 1 1/4" open end wrench to disconnect the oil lines on each side of the pump. There will be a small return oil line at the bottom of the pump to remove. There will be four 1/2" bolts about 4" long to remove from the front of the engine block that connects the pump frame to it. This unit is heavy! Suggest you wear leather gloves and use a lift or get help from a friend. Been there, done that!!
