Regarding the cylinders on the outer wing wheel standards on the XH1500. These are part of the Hydraulic Phasing Level Parallel Lift System. They are tied into series with the center lift cylinder and are phased down in size from the center cylinder 3 ½” X 8” to right wheel standard cylinder 3 ¼” X 8” to left wheel standard cylinder 3” X 8” then back to the center cylinder. These 3 cylinders have a grooved port at the top of the cylinder that allows oil to bypass from one cylinder to the next so all 3 cylinders work as one. The FX1800 uses a loose link to tie the center section to the main deck and they are used for a parallel level lift.
