KIOTI CK3520 · FLAIL MOWERS
The base CK3520 manual has 30.9 PTO hp; CK3520H has 28.9. Both share a 34.9 gross-engine-hp rating. That makes the TMG-TFM60’s unlabeled 30–60 HP range a different question for each transmission: an engine-based minimum includes both, while a PTO-based minimum excludes HST. Keep the exact base-model configuration in the inquiry.

BEST MATCHES FOR THE CK3520
19 of 23 flail mowers we track pass the published power, hitch and speed screen on at least one configuration. Each still has a detail to confirm with the seller.

THE DECISION IN NUMBERS
TMG must confirm the horsepower basis. The separate manual limit is 50 PTO hp; it does not define the minimum. Neither column establishes complete fit.
Scroll the table sideways on smaller screens.
| Base CK3520 configuration | If the range means engine hp | If the range means PTO hp |
|---|---|---|
| Manual | 34.9: within 30–60 | 30.9: within 30–60 |
| HST (CK3520H) | 34.9: within 30–60 | 28.9: below the minimum |
For the HST tractor, 34.9 engine hp is above 30 but 28.9 PTO hp is below it. TMG must identify what its range means. The separate 50-PTO-hp maximum in its manual does not clarify the minimum. Do not use an invented lower operating speed, rounding or an SE specification to turn the unresolved result into a pass.
The manual tractor’s 34.9 engine hp and 30.9 PTO hp both fall within the generic 30–60 range, and its PTO output is below the manual’s 50 hp ceiling. TMG still publishes conflicting operating weights and cutting widths. Confirm the exact offered revision and complete fit rather than converting a numerical power check into a recommendation.
The LFS range is 15–35 HP with an unspecified basis. Both CK3520 engine and PTO outputs fall within that band, but the missing basis is still a specification question. Compare the required cutting swath and material limit only after Farmry confirms the model/revision. Base CK20 rear remotes are optional, while the researched LFS and TFM60 are fixed mowers; do not confuse those models with hydraulic side-shift versions.
Farmry rates the HFS87 at 30–85 hp without saying whether that is PTO or engine power, lists Category I and II, cuts 87 inches and weighs 1,299 lb with the shaft. Its 34.9 engine hp is inside, as is the 30.9 PTO hp, but the 28.9 PTO hp is 1.1 short of 30, so the answer depends on which figure Farmry means; ask before buying. Its published lift at 24 inches, 1,631 lb, is only 332 lb more than the mower’s weight, so weigh the complete mower and check ballast first. Its gearbox rating, 50 hp, is not below this tractor’s PTO power. The 87-inch cut is 3 inches wider than Land Pride’s FM2584. Farmry’s page listed it at $4,499 on November 14, 2026.
Farmer-Helper rates its standard-duty FH-EF mowers by PTO power, all to 45 PTO hp with a 45-hp gearbox: the EF95 (37-inch cut) from 15, the EF105 (41-inch) from 16 and the EF125 (48-inch) from 20. They carry Y-blades for grass and light brush. The KIOTI CK3520’s 30.9 / 28.9 PTO hp is inside all three. Its published lift at 24 inches, 1,631 lb, carries even the 390-lb EF125 with 1,241 lb to spare. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
