FAQ: DR Stump Grinders
Q: How much assembly is required and how long does it take?
A: You will need to attach the brake and the handlebars, connect the throttle cable and wire harness, then add gas and oil. It should take no more than 30-40 minutes.
Q: How does the DR Stump Grinder operate?
A: Operation is quite simple: Position the DR Stump Grinder over a stump, lock one wheel in place with the wheel brake (left hand), engage the cutting head (right hand), and pivot easily from side to side, shaving off an inch or so with each pass. Reposition the machine and repeat until the entire stump is reduced to a pile of wood chips.
Q: What is the maximum stump height I can grind?
A: First, always cut the stump down as low as possible before starting. Removing 6" of stump with a chainsaw will go a lot faster than with a grinder. We recommend getting the stump down to a height of 8” or less.
Q: How far below the surface will it grind?
A: Approximately 6”.
Q: How fast is the self-propulsion (on the PRO XLSP model)?
A: The PRO XLSP model has variable speed drive up to 3.4 mph.
Q: How easy is it to maneuver the push models?
A: The DR push model Stump Grinders (PREMIER, PRO and PRO XL) require a firm push to set them in motion but then they roll quite easily on flat terrain.
Q: If I am trailering to the jobsite, why would I need self-propulsion?
A: The self-propelled model is designed for traveling on hilly or uneven terrain. It gives you the ability to travel from stump to stump without trailering. If you have stumps on slopes, you can get by without self-propulsion by starting high (uphill) and working your way down.
Q: Can I use the optional tow bar with the self-propelled model?
A: No. If you choose the self-propelled model you will need to put it on a trailer or in the bed of a truck or UTV to transport longer distances.
Q: How long will the grinding teeth last before needing replacement?
A: There are just too many variables for a simple answer but, in most cases, you should get 20-25 hours of use before needing to replace the teeth. Remember that the teeth have three positions, so if the pace of work slows down it may be time to rotate each tooth to a fresh cutting edge.
