Per Mike P's request, here's some pics and info on my cubs.
This is my 1650 with snow thrower. tractor was free as it would not run right intermittently and previous owner gave up. The only thing I found wrong was a bolt in the intake. I picked up the snow thrower and added dual hyd using a valve with float postion off a JD 317. Its not the prettiest, but runs the thrower and tiller well, and it was even delivered for free!
Next is my 782. It supposedly had a new KT17 series II in it with govenor issues. price was a little too good, but given the overall condition, I bought it. I believe the engine was new, but was left outside with no air cleaner and hood or something. cylinders were full of rust while everything else looked like new. steering, trunnion, etc all in great shape, so I picked up a low hours Magnum 20hp and dropped it in. I sold the hub caps and series II block for what I paid for the mag 20, so it all worked out ok. Like the 1650, I added dual hyd using a valve with float position. I really enjoy running this one. The magnum is so smooth.
And then there is the 125 with loader. It had been sitting for quite some time and needed work, but nothing too bad, and it was free also! Took me a few hours to finally get the motor to fire, but it had ran really well ever since. It did blow the head gasket the other day, but that's fixable. It will soon have lights, a wide frame front axle with spindle upgrade, and chain hooks on the bucket (doing that today which is why the bucket is off in some pics). I really haven't got to use it much, but it's been fun so far.
I guess I better throw in a pic of my old 122. she's the one that started it all for me. Old girl has never let me down. As a reward, I sent her to my fathers to haul fire wood out of the woods. He's known for being hard on equipment, but she'll take it. Based on what he has said so far, I may never get it back though. I think he likes it! Ok, I'm tired now.
