Yes. Pins are included.
Will it fit my machine?
Tell us your machine, we confirm the fit before shipping. Pin-on attachments are sized from your machine's pin diameter, pin-to-pin distance and ear width. If your machine has a quick coupler, is a long-reach model or was modified, measure those three and send them to us before you order. If it doesn't fit and the mistake is ours (our salesman, our Compatibility Check or JMA), the JMA Fitment Promise makes it right: tell us which fix you prefer (a modification at a repair shop near you paid by JMA once we approve the shop's quote, a free exchange, or a full refund of the product and shipping when you contact us within 14 calendar days of delivery), and our management team reviews the claim and sends its approval decision within 1–2 business days.
How fast does it ship?
In-stock items ship from Doral, FL the same business day when ordered before 2 PM ET; orders after 2 PM ET, on weekends or on holidays ship the next business day. Carrier estimates for the lower 48, in business days from the ship date: parcels of 50 lb or less 5–7 standard or 2–4 expedited; LTL freight over 50 lb 7–10 standard or 4–6 expedited, usually with a delivery appointment and a signature. Outside the lower 48, shipping is quoted. Inspect it before you sign and note any damage on the delivery receipt.
What does the warranty cover?
Defects in materials and workmanship are covered for 2 years or 2,000 operating hours, whichever comes first: year 1 parts and pre-approved labor, year 2 parts only. Lifetime warranty on structural welds. Teeth, cutting edges, pins and bushings are wear items and are not covered. Get our written approval before any repair.
Can I return it?
Yes, for standard products: a refund within 14 calendar days of delivery, or store credit within 30, if it is unused, uninstalled, free of soil and grease, and in its original packaging with all hardware. Get a Return Authorization Number (RAN) from us first. The buyer pays return shipping unless the item was defective, damaged or wrong because of our error, or you can drop it off at our warehouse, 8024 NW 29th St, Doral, FL, Monday to Friday, 9 AM to 5 PM, with your RAN. A restocking fee applies to non-defective refunds; store credit has no restocking fee. Original outbound shipping is not refunded on change-of-mind returns. Installed or used attachments can't be returned, except under the JMA Fitment Promise: if it doesn't fit and the mistake is ours (our salesman, our Compatibility Check or JMA), a careful fit check is allowed and the Fitment Promise applies.
