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 we confirmed the fit from your accurate machine and coupler details and our recommendation is wrong, report it within 14 calendar days of delivery: the JMA Fitment Money-Back Promise gives a full product refund, outbound and return freight covered, no restocking fee.
