5740C with about 50 hours. I have only had two problems with it so far. The cast metal piece that bolts onto the A/C compressor that has broken twice. It has been fixed both times under warranty. I hear that it has been a problem with many owners, so hopefully they will develop a stronger part. The other thing was some bolts on the front axle loosened up and nearly fell out. Luckily we caught it in time.
Other than that it hass been good. I use it in my vineyard for mowing, spraying and carrying big stuff around. I also use it in construction for box-blading, grappling brush, etc. I'm definately glad I got the 4WD. I need it frequently doing the construction type work on irregular terrain, but not so much in the vineyard.
It has a FEL. It works good and will lift just about 2000# like the manual says. I also bought the Montana box blade. It works good, but I did bend the plate that the shanks mount to by digging out roots in 4-LO-1. I recently bought the 7' HD rotary cutter. It is basically the heavy duty King Cutter, except it was cheaper through Montana that if I had gone out and bought a King Cutter branded unit. It works good. So far I have only torn one of the wheels off the back - perhaps I am a little hard on my equipment.
So far I am pleased. I am curious what is in the works for that A/C part.
