TYM · COMPACT TRACTOR ATTACHMENTS
This guide covers the mechanical 12F/12R, ROPS T394 in TYM’s current North American brochure and January 2026 catalog. Its exact 30.2 PTO-hp value creates a useful boundary: it exceeds WC46’s published maximum of 30, while clearing FM-78’s minimum of 30 by only 0.2. HST marketing and the separate T394C cab column are outside this profile.

North America 2025/2026 specifications · mechanical 12F/12R · 4WD · ROPS
North American T394 mechanical F12xR12, 4WD and ROPS with Yanmar 3TNV88-CR, as specified in the current exact-model brochure (Aug 2025 library label) and January 2026 Series 3 catalog. Excludes T394C cab, T394NH/SH HST, successor models and unverified serial ranges. Current HST marketing is not used to assign this mechanical PTO output to HST tractors.
Current marketing describes HST; current brochure and January 2026 catalog specify Mechanical F12xR12 in the exact T394 column, with 30.2 PTO hp. Adjacent T394C column says 30.
Publish only the mechanical ROPS document scope. Do not merge HST or cab outputs; confirm the owner’s transmission and serial-applicable manual.
Current sources: 1,558 lb at 24 inches and 2,639 lb hitch lift. Older NA mechanical manual: 2,646 lb hitch and 1,764 lb in a behind-link-ends row with no distance.
Use the current table’s explicit 24-inch rating for this guide. Ask TYM to identify the missing measurement distance and the applicable tractor revision before relying on the older 1,764 lb figure.
Current sources: 6.1 implement / 4.4 steering / 10.5 total gpm and optional one or two remotes. Older manual: 6.3 / 4.6 / 10.9 and optional one.
Preserve both document scopes; do not choose the higher flow or infer fitted hardware. Rear delivery and system pressure remain unknown.

FROM YOUR TRACTOR TO THE JOB
The mechanical ROPS T394’s 30.2 PTO hp puts the fixed FM-62 and FM-78 into different practical comparisons. The 55-inch FM-62 is only 1.5 inches wider in total than the tractor’s published 53.5-inch width. FM-78 adds 15 inches of cut, but its 30-hp minimum is just 0.2 below the tractor rating—and its Y version does not have a lower minimum than hammers.
Read the guide →FIELD GUIDEThe mechanical ROPS T394 has 30.2 PTO hp in both the current exact-model brochure and the 2026 catalog. That is above WC46’s published 30-hp maximum, even though the difference is small. WC68, the current FH-BX62 manual range and MX-9900 offer different feed and load questions once the exact tractor configuration is confirmed.
