Problems: 7410 John Deere with power quad transmission. I have had it work in reverse and it sometimes works. It could be clutched again and worked. I then let it idle and tried reverse 2 to 3 times to get it working. When it works, it doesn’t slip. All speeds forward are perfect. Today, i tried again. The only way I could get to work was to let the engine idle and then release the clutch halfway.

Reverse engagement could be affected by a number of factors. Most of these issues relate to the Forward/Reverse Shift Valves. Broken springs on the forward/reverse switch valve are the most common cause for reverse engagement loss. The forward/reverse changing valve is located in the housing at the bottom power quad. Below I have attached a detailed diagram of the valve housing which shows the #8 shuttle vale.
One of the springs can break, causing the engagement to be delayed. In this case the engagement can become very aggressive. This is the cheapest repair as the lower chamber can be removed.
The bottom of your power quad contains a shift valve. This control forward and reverse as well the four powershift gears. A spring can often break, causing floating pieces to stop normal modulation. You will lose the direction you are moving more often than not. Loader tractors are most likely to experience this problem because they have more forward reverse motion.
The valve housing is easily accessible. The driveshaft must be first removed. The three deferent bolts holding the valve housing down towards the bottom power quad are called the “deferent length bolts”. You’ll also see that the two bolts feature the copper sealing washers, #9 in the diagram. It is critical that the spool house is not damaged or otherwise compromised. Make sure that the #25 quad detent (power-quad detent) is in perfect condition.
The replacement gasket can be purchased as full plates, which include both gaskets.
This is where you should start. These three springs and center spools are identical, making it easy for you to see if there is any damage. The three valves used to control the powershift speeds are Reverse, Froward and Enable Pressure spool. The other spool holds four powershift speeds.
