As others have said, it was not an official recall and NO notice was sent out by Deere to machine owners. In fact, many dealers learned of the issue from members here on GTT when the members were requesting the bracket be replaced. Such was the case with my dealer. When I requested the bracket assembly be ordered, it was the first one ordered by any of the 18 locations in the dealer I work with.
I paid for the bracket myself and changed it immediately upon learning of the issue. Many people made the decision to not change the bracket and indicated they would "deal with it if something happened", which is the owners choice.
If the engine is being replaced and the top cover cracked under the air cleaner housing, Deere should be paying for the new engine and the labor to replace it. Other than you paying for the engine oil and maybe a few other small charges, Deere should be covering the cost. The dealer orders a new Yanmar crate engine, returning your old engine as the core. The fluids are not covered under the Deere manufacturers warranty, which is why I mentioned it. Many dealers simply absorb the cost of the motor oil, where others charged their customers for the 3 quarts of motor oil as indicated in the Residential Warranty Statement for this equipment.
Realistically, the problem existed for models from 2013 to 2018 (early year models) before the bracket and air cleaner assembly was changed at the factory. All 1025r models from 2013 to 2018 early models used a similar style mounting bracket, however, there were some differences in the thickness and shape of the saddle brackets and securing rubber straps.
Some styles of the bracket fractured and created worse vibration, some did not. The brackets which tended to fracture were thinner metal than those which did not fracture. The rubber straps which secure the air cleaner filter canister to the metal saddle bracket failed in many cases, by actually wearing through and splitting.
The 1026r NEVER had the troublesome bracket and used a bracket and system very similar to what Deere ultimately is using now and used to replace the air cleaner assembly bolted to the engine. The 1026r air cleaner canister was mounted to the radiator core support, instead of the top of the engine. Why the change in 2013 to the saddle style bracket with the rubber strap was made when the model changed from the 1026r to the 1025r has never really been revealed that I have seen.
The 1023e uses the same air cleaner as the 1026r and never had the saddle bracket involved on that model. The 1025r with the old style "trouble" bracket is shown in the bottom screen shot. The replacement air cleaner now used is very similar to the air cleaner used in the 1026r and the 1023e originally.....
