The Baumalight 3P40 PTO Stump Grinder is built for serious performance. With a massive 34" rotor, 52 carbide-tipped teeth, and a powerful HPR gearbox, this unit is ideal for tractors with 60–120 HP and a 1,000 RPM PTO. It quickly devours large stumps with cutting depths of up to 14" below ground, making it the most aggressive and efficient PTO grinder in the lineup.

  • Designed for 60–120 HP tractors with 1,000 RPM PTO

  • 34" heavy-duty rotor with 52 replaceable carbide-tipped teeth
  • Cutting range: 25" above and 14" below ground
  • Direct drive from PTO to rotor for maximum torque transfer

Controlled Cutting Power with Smart Features


Engineered for fast, smooth, and consistent grinding, the 3P40 includes hydraulic swing and lift cylinders, flow control, and an optional external control arm for tractors with limited remotes. The massive rotor and HPR gearbox produce 803 ft-lbs of torque at 810 RPM for unmatched performance.

  • Optional S1050 External Control available for tractors with only one remote
  • Swing cylinder provides 65° grinding range without repositioning the tractor

  • ¾" thick rotor resists flex and provides momentum through tough material
  • Heavy-duty stabilizer base improves stability and reduces stress on tractor
  • Floating deflector manages debris and flips up when space is tight
  • Spring bushings made from hardened chrome-vanadium AISI 6150 steel

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.

If there is a manufacturing defect in the product, or if the product is not functioning as intended, please provide proof of the issues with either pictures or videos to this email: info@attachmentspros.com, or call our support team at (800) 331-2926.

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. Please allow 5-7 business days from the date we approved the return for your refund to be reflected in your bank or credit card statement. If over 7 business days have passed since we approved your return and you haven’t received your refund, please contact us.
