Toro reel master
I am the maintenance tech for a small local golf course and I’m currently working on a toro reel master 3555-D model 03820
This machine is having issues with the front left hand cutting unit (#4) dropping significantly lower than the other 4
I have rebuilt the cylinder twice(preforming piston seal bypass tests each time) , swapped hoses to make sure it’s not internally bad, installed a new cartridge valve for S1, checked to see if have correct pressures coming from my pump(2000psi) confirmed all solenoids ohm out correctly( per book specifications), swapped the cylinders to make sure the problem is isolated on the left hand side(it is) checked that my relief valve pressure are correct with speciations from the book
I am at a complete loss any help that you can give will be much appreciated
EDIT:: found the problem a piece of the piston seal has lodged itself in the flow control in OR1 thank you for everyone’s input ✌️
