Sub-compact tractors (Kubota BX, John Deere 1 Series, Kioti CS, Mahindra eMax) need attachments sized for their lift capacity, PTO HP, and Limited Cat I hitch geometry. A standard 6-foot rotary cutter weighs more than most sub-compacts can safely lift, and standard Cat I implements may not seat correctly on Ltd Cat I lift arms.
Every attachment below has been flagged by the manufacturer as appropriate for sub-compact tractors, typically meaning it weighs under 500 pounds, requires under 25 PTO HP, and is sized 48 to 60 inches wide.
Always verify the hitch geometry against your specific tractor before purchase. Many sub-compacts use Limited Cat I, which has narrower lift-arm spacing than standard Cat I.
