Belt adjustment on Rayco RG1625 super jr

[CT arborist]

Hi Everyone,
Can anybody guide me on how I adjust the belt on my Rayco stump grinder. It's starting to slip even on soft wood. Teeth are fine I did replace them about 10 months ago. Here are some pics. thanks all!

I doubt your teeth are still fine if you've been grinding with them for ten months..... That being said, there are four bolts holding the motor down, loosen those, then there's a square head adjustment bolt at the base of the motor on the side towards the cutting wheel, that will slide the motor away and tighten the belts.

½ deflection using 18 to 20LBS of force according the Rayco manual for the V belt. This can be measured with a plunger gauge. I’m with Ben84 on the teeth. Call Rayco and get a manual as you will find it very useful and throw some Greenteeth on it (just my biased opinion).
