A few months ago I put up a thread about my walker running hot (Walker overheating). Some said they wanted an update when I got it. Well, here it is. I finally got my mower back today as it has been gone about 5 to 6wks in the shop. This last episode begane after the fan blade broke again, and it did a lot of damage to the radiator. I called my dealer about the cooling fan breaking for the 3rd time. They called the distributor who said they will cover the fan but will be the last time. After receiving the fan, I took the radiator out and found the blade breaking did a lot of damage to the radiator. The fan blades were warped too. After another call to the dealer, who in turn called the distributor, who in turn said they won't cover the radiator, I was fuming. Called my walker distributor who told me they were done with this mower and would not do anything else about it and said walker told them the same thing. I called walker and they said that wasn't true. Walker ended up requesting pictures of radiator which I already took, and wanted the fan blade back. About 1wk after they got the pics and fan blade, Walker called and said dealer had installed a fan blade that had been recalled and was going to replace radiator, fan, fan motor, and fan shroud. I was asked to take it to a different dealer "more qualified" to look at the overheating problem. After they replaced the parts, they test drove it and it ran hot on them too. The distributor called and the mower ended up at a kubota dealer which is 3hrs away from me. They went through the motor said nothing was wrong. My distributor finally stepped up to the plate and started fighting for me after more than a year of me dealing with this mower. He said he had to fight for it but got them to check the injector timing on the motor which ended up being 5 degrees off. I got the mower back and mowed with it and it runs even cooler than before and never got hot. Runs perfect. Don't know if I will stick with walker or not. I got an Exmark to replace it as I have been dealing with this for over a year. Wow, the Exmark is fast!
