I too was not so lucky. I've been cutting stud wood and logs and skidding them out. I usually cut around the big spruce and fall them last since they make the most brush. I don't like driving over the heavy brush. Anyway, the other day, I had fallen and limbed a couple big spruce that would give me enough for a load.
Since I was almost done, I started to rush. I drove over some heavy brush to get turned around. I got hooked onto the log and when I started up a small hill, the tractor was making a strange noise. From the seat, it sounded like the hydraulic pump. Almost like it was cavitating.
I got off the tractor and walked to front and saw coolant puring out of the bottom of the radiator /forums/images/graemlins/shocked.gif. I shut the thing off but couldn't really get a good look. I started back up and drove to my yard where I could get a good look.
Still couldn't see where it was leaking, so I pulled the radiator out and a stick must have pushed on the bottom of the radiator and cracked the bottom tank (its plastic) where the mounting post fits in the frame /forums/images/graemlins/frown.gif.
I called the dealer. $530 bucks /forums/images/graemlins/shocked.gif. So, I spent 3 days running around between radiator shops and plastic repair shops and no one could guaratee a fix. I did find a plastic welder who welded it and also did an epoxy patch but he wasn't sure it would hold. I got home and filled it with water and it was still leaking where the core meets the header. Back to the radiator shop, who were kind enough to tell me I was screwed.
I ordered the new one. While the tractor sat idle and I waited for it to come in, I noticed a large pool of hydraulic oil on the ground under the filter. Hmmmm. It seemed another stick had bent the tube that goes from the tank to the filter and broke the seal at the filter end. I ordered one of these as well. $35.
It took about 45 minutes to get the new radiator installed. Started it up and the hydraulic pump was still making that whining noise. I drained the hydraulic fluid, installed the new tube and seals filled up the fluid and started it up. No more leak, and no more noise from the pump. The pump must have been picking up air from the leaking seal. /forums/images/graemlins/grin.gif
Everything is back to normal except my bank account.
