Fits Skid Steers and Small Excavators

The S18 Stump Grinder is designed to work on both skid steers and small excavators. With a quick pull of two pins, it easily switches between mounting systems. Its compact size makes it ideal for tight spaces, and the fixed heavy-duty deflector keeps debris under control. The rotor is uniquely positioned to give the operator an excellent view of the grinding action, improving accuracy and safety.

  • Dual mount: fits skid steers and excavators
  • Quick-swap mount with 2-pin release system
  • Compact build for tight-area stump grinding
  • Fixed deflector for safe, clean debris control
  • Clear line of sight to rotor for better operation

High-Speed Teeth with Easy Replacement

The S18 uses a high number of concave-shaped carbide-tipped High Speed Teeth—each with 3 usable edges that can be rotated for longer life. This means less work per tooth, smoother cutting, and fewer replacements needed. All teeth are bolt-on and field-serviceable. A free 6-pack of replacement teeth is included with every unit.

  • Carbide tips with aggressive cutting action
  • Teeth rotate 3 times before needing replacement
  • 1¼" tooth extension prevents clogging
  • 6 free replacement teeth included
  • Bolt-on design for easy field changes

Powerful Rotor and Custom Hydraulic Motor Options

The S18 comes with three hydraulic motor options to match your flow rate. The ¾" thick steel rotor anchors the cutting system and adds momentum to push through tough stumps. For example, using an S450 motor at 12 GPM and 2500 PSI can grind a 24" stump in 60 minutes—reduced to 50 minutes at 3000 PSI, and even faster with 15 GPM. Zinc-plated greaseable pins prevent corrosion for long-term durability.

  • ¾" solid steel rotor adds strength and momentum
  • 3 hydraulic motor options to match your machine
  • Efficient grinding with no swing cylinder
  • Zinc-coated greaseable pins for smooth joint action
  • 10" below-ground cutting depth

Returns

Please note that not all orders are eligible for return once they have been dispatched. Because we source products directly from manufacturers, we must adhere to their return policies. Additionally, built-to-order items are custom-made for your order and are therefore not eligible for cancellation or refund.

For eligible items, you have 30 days to return the product in new, unused condition for a refund. All returns must be authorized in advance. To start the return process, please contact us at info@attachmentspros.com or call (800) 331-2926 with your name, order number, and the reason for your return. Unauthorized returns will not be accepted.

Note: Once a product has been installed, used with equipment, connected to hydraulics, or shows any signs of wear or operation, it is no longer eligible for return—unless it is being evaluated for a warranty issue.

Return Shipping Costs

Return shipping and insurance costs are the responsibility of the customer, unless the return is due to an error on our part. We recommend using a trackable shipping method and considering insurance for your package, as we are not responsible for items that are lost, stolen, or damaged during return shipping.

Restocking Fees

Some manufacturers charge a restocking fee for returned items, typically between 5% and 20%. These fees will be the responsibility of the customer. However, we evaluate each return individually and will do our best to have the fee reduced or waived whenever possible.

If a return is initiated due to any of the following reasons, restocking fees will be completely waived: the items are defective or not working, the items do not match their description or photo, the wrong items were shipped, parts or pieces are missing, or the product arrived damaged.

Exchanges

If you've ordered an item that doesn’t fit your machine, we’re here to help coordinate an exchange.

To begin, simply return the original item. Once we’ve received and approved the return, you can place a new order for the correct product.

Please note that exchanges follow our standard return process, including any applicable restocking fees and return shipping costs.

Cancellations

Please note that built-to-order products are made specifically for each customer and cannot be canceled or refunded once production has started.

If you need to cancel an order that has already been shipped, please be aware that return shipping costs will be your responsibility. If you made a mistake and wish to cancel your order, please contact us as soon as possible via email at info@attachmentspros.com, through the chat in the bottom right corner, or by calling us at (800) 331-2926.

Damages and Defects

If over 7 business days have passed since we approved your return and you haven’t received your refund, please contact us.

Warranty

All products are covered by the manufacturer’s warranty unless otherwise stated. Warranty terms vary by brand and product, so we encourage you to review the warranty information listed on each product page. Attachments Pros does not offer additional warranties beyond those provided by the manufacturer.

At Attachments Pros, we stand by our commitment to provide you with both outstanding quality and unbeatable prices. If you find a lower price on the same product from another authorized online retailer, we guarantee a price match and will strive to beat it if we can.

To initiate your price match, just present proof of the lower price through a link or a screenshot.

Price Match Guidelines

  • The product must be identical, sold by an authorized online retailer.
  • We do not match prices from physical stores or auction sites such as eBay or Amazon.
