I would appreciate any wisdom offered. I have a 2020 Workmaster75, it has been in the dealership since 10-2024.
They have not found the problem as of yet. I have contacted corperate and they are trying to help. problem is the dealership lost every expierenced tech on staff.
the tractor has been taken apart several times, and several parts have been replaced to no availe.
Has any one on here had the same or like situation and how did you resolve it.
I dont think that my tractor will ever be solid with all the things that were tried with out success.
The engine bay and dashboard have been opened up by the dealership account over 5 times.
The only tech at the dealership was hired and sent thru a two week class that lasted the entire month of Novemeber.
I bought this tractor when i retired from my day job thinking this would be the one the kids would have to get rid of in the auction when i'm gone..
Like i said the rep from cooperate jumped on the situation, but i am still getting reports of the dealership of waiting on a part, getting new codes for yet another system on the
machine.
I’m not sure, it has been a long time and my memory may not be exact, but maybe this will help you.
When I was turning wrenches back in the ‘80’s many vehicles came in with hard and intermittent electronic issues. Some of the hard issues we confidently knew exactly what it was and the repair completion was easy (even though it could involve major disassembly) but it also depended if the dealership had the part in stock.
Some hard and intermittent electronic issues were not so easy to correct. Sometimes we had a bad electronic part that failed when it became hot, those parts were coveted and held on to by the technician, (if warranty/customer didn’t require the part returned) because that part could be used in future diagnostics.
Most if not all electronic parts had an isolated diagnostic procedure that indicated/pass fail parameter with a % allowance in resistance or voltage. When the book/procedure said the part was out of parameter (and bad) it was supposed to be replaced, BUT replacement did not guarantee the problems was solved because the ECU depended on all inputs and some of those inputs were dependent on other inputs that might be near the fail parameter.
This made for a difficult repair because the dealership usually did not stock the part, the part had to be purchased and could not be returned, the customer had to wait, the mechanic had to clear his bay, and the customer was not always assured the purchase of the part would correct the issue.
At that time, the same challenges existed with some diagnostic machines that failed to progress the diagnostic procedure until the suspected failed part is replaced (repeat scenario). Unless the failed electronic part was systemically repeated across the brand the repair typically required straight time and a lot of it.
Unless you have a shop with well paid technicians on salary, straight time (not flat rate) was not welcomed by the technician.
We had one vehicle that would accelerate without warning and the diagnostic machine was all over the place in terms of intermittent faults and when those parts were isolated and tested some parts passed and failed, but the replacement parts NEVER corrected the uncontrolled acceleration issue. Finally, the luxury car was shipped to headquarters and a team of engineers worked on it to diagnose the problem. Months later we found out the wiring harness was faulty and was creating make break and high resistance connections. The engineers replaced the wiring harness and the problem was solved. I don’t know if the customer got a new car, but warranty paid for all that work including the earlier time for the technician. But if a vehicle was out of warranty the customer was expected to pay for all the parts that were replaced that did not solve the problem.
This is one reason I steer clear of equipment and vehicles that rely heavily on electronics, but you really cannot get away with that now.
Thanks for your time, I hope this helps.
