Powerful and Simple Skid Steer Stump Grinding


The Baumalight S18 Skid Steer Stump Grinder is built for rugged, no-nonsense performance. With no electrical connection required, it uses a direct hydraulic drive to deliver maximum torque and RPM to the cutting head. Designed for simplicity and durability, this grinder gives you excellent visibility, minimal maintenance, and unmatched grinding efficiency.

  • No electric hookup required — plug-and-play simplicity
  • Direct flow hydraulic drive — no power loss to swing cylinders
  • Available with multiple motor options to match your skid steer’s GPM
  • ¾" thick steel rotor anchors the cutting system for tough jobs
  • Excellent operator visibility of the grinding action

Durable Cutting System with Carbide Teeth


Equipped with carbide-tipped high-speed teeth, the S18 is built to cut through even the toughest stumps. With more teeth doing less work, the grinder operates smoother, lasts longer, and requires fewer tooth replacements. The extended tooth clearance ensures better chip flow and less heat buildup during operation.

  • High-speed carbide teeth with 3 cutting edges per tooth
  • Teeth extend 1¼" from rotor for better chip clearance
  • Includes 6 FREE replacement teeth stored in an onboard container
  • Bolt-on tooth design makes replacements fast and easy
  • ¾" thick rotor provides extra cutting momentum and eliminates flex

Built to Match Your Skid Steer Flow


The S18 is offered with three hydraulic motor options to match your equipment’s flow. Whether you're operating at 12 GPM or 15 GPM, this grinder delivers dependable results. And with zinc-plated greaseable pins and optional mini skid steer mount, it’s ready for years of reliable service.

  • Choose from S450 motor options to match your flow and PSI
  • Grinds 24” stumps in 50–60 minutes depending on PSI and GPM
  • Double-pin system allows quick install of mini skid steer mount
  • Zinc-coated greaseable pins resist corrosion and ensure smooth joint movement

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 you receive a damaged shipment, please document this on the freight delivery record and take pictures of the damages. Keep all packaging and notify us within 24 hours of receiving the merchandise at info@attachmentspros.com or call our support team at (800) 331-2926. We will process an insurance claim on your behalf.

Refunds

You will be notified once your return is received and inspected, typically within 4-7 business days. Approved refunds will be issued to the original payment method used when placing your order.

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.

  • 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.
