F Series Front-Mount Mower
The F series is Kubota's premium front-mount diesel mower line, designed for commercial landscapers, municipalities, and institutional groundskeepers. With Kubota diesel engines, shaft-driven PTO, 4WD, and front-mounted decks up to 72 inches, the F series delivers maximum visibility, maneuverability, and year-round versatility with snow equipment and other front attachments.
Front-Mount Deck Advantage
The front-mounted mower deck gives operators a clear view of exactly where they're cutting — no guessing about the deck edges behind you. This improves trimming accuracy around obstacles, reduces the need for string trimming follow-up, and allows mowing under low-hanging trees and overhanging fences that would block a rear-deck machine.
- •Full visibility of the cutting area for precise trimming
- •Mow under overhangs, fences, and low branches
- •Reduces string trimmer follow-up time significantly
- •Out-front articulation follows ground contours independently
Kubota Diesel with Shaft-Drive PTO
F series mowers use Kubota diesel engines paired with shaft-driven PTO — no belts between the engine and mower deck. This eliminates belt maintenance and delivers consistent blade speed regardless of load, resulting in a cleaner cut and less downtime.
- •Kubota 3-cylinder diesel: 26 HP (F2690) to 38.5 HP (F3990)
- •Shaft-drive PTO — no mower deck belts to replace
- •Consistent blade speed for uniform cut quality
