as with most chain drives due to wear they stretch. Therefore adjustment is made by a slide, like on a motorbike or an adjustable jockey wheel. Looking at your log loader as there is two chains on the one drive shaft I would suggest you use a jockey wheel type of adjustment, one for each chain. I use the term jockey wheel in this case lightly as you would not get another wheel in to take up the slack, but you may be able to use a half round cam on the back side. Once you have the correct size and position glue in place onto the back board. Having said all that my first port of call would be to check the drive cogs on the drive shaft of the chain. If these are worn that is what could be your problem and causing the chain to slip back under load. Hope this helps.
