Hydraulic Failure Cancel The title field is required!

   I've got an Toro 5610D Fairway unit that had catastrophic hydraulic failure. The distributor said the hydrostat was bad and for the cost to rebuild the original one our option was to purchase a new one. On the first try out of the box we have failure again, this time the distributor is saying that we had an wheel motor failure. They said that the wheel motors should be replaced in pairs due to the type of failure that occured. They said that the wheel motors are in an closed loop and that any debris from one motor would more than likely be delivered straight into the other. Ok, I can buy that statement. You feed oil to one then it is delivered to the other. Now their saying that the new hydrostat is in need of rebuilding due to the fact that it is included in this "closed loop". Really! Are they saying that the most important hydraulic circuit on this unit is not protected by the two hydraulic filters located on the unit? Are they saying that out of four hydraulic circuits, traction, steering, lift/lower and reel motor operation that they place more emphasis on the others than the traction circuit? This section is used more times than all others, and probably used the heaviest. Any feedback on this is welcomed.

   If you used a hydraulic filter on a closed loop system it would have to be built extra heavy duty to handle 3000 psi hydraulic pressure produced by the system. It would also take significantly more horsepower to push oil at 3000 psi through a filter that filters particles down to microns.

   I've seen this a lot. When I worked for a Toro distributor we took a hydraulic filter and temporary plumbed into the closed loop. We raised the mower up on stands and started the machine warmed up the oil and pressed the traction pedal in the FORWARD direction only for approximately 10 minutes. If you reverse the pedal then you just blew all the contaminants back into the closed loop pump and motor. This always worked fine because we never built up hydraulic pressure because the wheels never touched the ground to provide resistance. The other filters are designed to catch contaminants on the return side of the tank. In my Hydraulic repair days we would take oil samples and run them across the microscope to check what contamination if any was left.

   Did the dealer replace the motor? if so did they do it without flushing the entire system? seems like the #1 thing to do when installing a brand new very expensive pump motor!!!!
   
   I could understand the desire to replace both wheel motors as one would have wear but my Fairway mowers are 12-18 years old and I do not have the dollars to replace two of them so we have replaced just one with no issues even without flushing the system! Never had to replace a motor though! them things are tough as nails and I get 18 plus years out of my fairway mowers about 15 out of greens mowers which become tee mowers at 10 years.
   
   Maybe that just the dealer code but seems to me that your getting your bill run up for nothing. Maybe the motor was not even the problem, who knows!
