I was lucky in the fact that after it locked up at 8:30 AM Sat morning, I had an identical 445 in my yard by noon. Just 10 miles away I found a 1999 with 312 hours that looked brand new. I bought it for 4800.00 I'm heavily invested in the 445. I have a 3 point hitch, mulching deck and a hyd tilt dump material collection system, along with many extra parts. I wanted to continue to use the collections system and the 4X5 series is all mine will work on. I found it interesting that I bought my blown one in 2002 with 280 hrs (it's a 2000 model) for 5200.00 and 12 years later I paid 4800.00 for one with 312 hrs. Since the bagger is so clumbersome to install and remove, I had often pondered the idea of a second 445 to leave the bagger on, and use one with the mulching deck for summer mowing and spraying using the 3 point hitch. When I added up all I need to repair the blown one, I got a total close to 4000.00 dollars using a Deere short block, muffler, water pump, thermostats and other misc. stuff. I found another 2001 about 30 miles away that is a cream puff. It has 450 hrs on it. No extra functional stuff, but nice shiny hub caps, and clean as a pin. They want 5000.00 for that one. So it seems my choices are, switch the rear hyds, over to my just purchased one and continue to switch the bagger off and on, repair the one I have spending about 4 grand, or buy another one for 5 grand and dedicate the bagger to it. I'm not really crazy about doing a repower with a different engine. I can see problems in the future with that. The smart thing is to probably forget about repairing my old one, forget about buying another one, and just one the one I bought. If I could find one with no deck and a few lumps and bumps, but a good engine, that would be an option, and just use the engine and save the rest for parts.
