Wehave had a reasonable wet winter this year, far wetter that recent times. I became very unstuck trying to negiotiate waste away from the sawmill. We only have a Hyster 3.5T fork and it does not like muddy ground. This is my cheap and cheerfull solution. About $100 worth of steel and a day in the workshop.

These forks just hang over the top of the skidder blade and can be fitted/released just by lowering the blade and driving under the "hooks".
The fork section is hinged at the base and retained at the top of the blade with a short piece of chain. This means you can adjust the angle of the forks, and to release the load you flip the chain out of the slot and the lift the blade.
