Frequently Asked Questions

How do I know whether a product will fit my tractor or equipment?

Review the product description, dimensions, hitch category, PTO requirements, shaft size, hydraulic specifications, mounting points, and compatible models before ordering. If you are unsure, contact us with your equipment’s make, model, year, and relevant measurements. Compatibility remains the customer’s responsibility unless expressly confirmed in writing by CropForge.

Does CropForge sell complete tractors or only equipment and parts?

CropForge focuses on farm machinery, tractor attachments, agricultural tools, livestock equipment, and replacement components. Please check each product listing carefully to confirm exactly what is included, as tractors, vehicles, batteries, hoses, mounting hardware, or accessories shown in photographs may be sold separately.

Are assembly and installation required?

Some products may arrive fully assembled, while others may require partial assembly, professional installation, adjustment, lubrication, or additional hardware. Assembly requirements vary by product. Always follow the manufacturer’s instructions and use a qualified technician when installation involves hydraulic, electrical, PTO, structural, or safety-critical components.

How can I check the status of my order?

When tracking information becomes available, it will be sent to the email address used at checkout. Tracking may take some time to update after the shipping carrier receives the package. If you have not received an update, contact us with your order number at fawoldwariop@gmail.com.

Can I change or cancel my order after placing it?

Contact us as soon as possible if you need to change or cancel an order. We will try to assist, but changes and cancellations are not guaranteed once processing or shipment has begun. Orders that have already shipped may need to follow the applicable return process.

Will every item in my order arrive together?

Products may be stored or shipped from different locations, so an order containing multiple items may arrive in separate packages and on different dates. Each available shipment may receive its own tracking information. Separate delivery does not necessarily mean that an item is missing.

What should I do if my item arrives damaged, defective, or incorrect?

Contact us promptly and provide your order number, a description of the issue, photographs of the item, packaging, shipping label, and any visible damage. Keep all original packaging until the matter is resolved. Do not install, operate, modify, or discard a damaged or incorrect product before receiving instructions from us.

Can I return a product if it does not fit my equipment?

Return eligibility depends on the condition of the product and the requirements stated in our Return & Refund Policy. Products that have been installed, used, fueled, altered, damaged, or assembled may not qualify for return. Customers should verify compatibility and specifications before purchasing.

Are warranties included with CropForge products?

Warranty coverage, when available, varies by product and manufacturer. Any applicable warranty terms will be stated in the product listing, packaging, or manufacturer documentation. CropForge does not provide additional warranties unless expressly stated in writing. Normal wear, misuse, improper installation, unauthorized modification, and incompatible use may not be covered.

What safety precautions should I follow when using farm equipment?

Read and follow all product manuals, warning labels, and manufacturer instructions before assembly or operation. Wear appropriate protective equipment, keep guards and shields installed, and never service machinery while it is powered or moving. Agricultural equipment should only be operated by trained individuals and within the product’s stated limits.
