ATRACYPART Tail Wheel Caster Fork for Bush Hog Rotary Cutter — OE#63740 Replacement, Powder-Coated Steel, Fits 4'/5'/6' Decks

ATRACYPART heavy-duty tail wheel caster fork replaces OE# 63740 to restore stable rear support and smooth tracking on Bush Hog and compatible rotary cutters.

Built to match the common mounting dimensions for 4', 5', and 6' decks, the fork is machined and welded to resist bending, slips, and corrosion so you can get back to productive field work without fabricating parts.
