PO# [protected] - I purchased a John Deere 5075e tractor in December of 2020 with a 520m loader and I also purchased a rotary mower John Deere MX7 at the same time for my landscape business. I did not use it very much during the cold months. In the spring of 2021, I began using the tractor for garden tilling jobs as well as other landscaping projects. I noticed that it was leaking a significant amount of antifreeze on the floor in my shop. The local dealership where I bought it sent someone out several times to repair it. The leak continued and the dealership came and picked it up keeping it for two weeks and could not find the leak. I contacted a second dealership when I noticed that there was still a leak. They repaired the overflow hose clamp. This did not fix the leak. I used it for another job and it ran warmer than normal. It has now been in the shop again for two more weeks during my peak season. The delearship found that the radiator is defective and a replacement is not available until September 24. They tried to get a local radiator repair shop to make temporary repairs. It could not be repaired and now they are replacing the radiator with an aftermarket radiator. I still have not received my tractor back as of today August 13, 2021. This has been an escalated repair ticket. I have had to turn down work and lose customers because I did not have the equipment for my business.
