Demo 2025 Ventrac MJ840 Contour Mower Attachment For Sale!

The Ventrac MJ840 Contour Mower (Stock Code 39.55160) exists for one purpose — delivering a pristine, professional-grade finish on terrain that would defeat any conventional mower deck. The three-deck system spans 83 inches of total cutting width, with the two outer wing decks floating independently of the center deck with up to 40 degrees of motion each. As the tractor moves across slopes, swales, mounds, and transitions, each deck reacts independently to the ground beneath it — maintaining consistent blade-to-turf contact at every point across the full cutting width simultaneously. The result is a perfectly even cut without scalping on terrain that challenges every other mower in the field.

Front-mounted per Ventrac's out-front design standard, the MJ840 keeps all three decks in full view of the operator at all times, allowing precise navigation around bunkers, cart paths, water features, and obstacles that define high-end course and resort management. Full-length rear rollers behind each deck deliver consistent cut height, firm turf contact, and clean striping across every pass — the finishing detail that separates a managed course from a merely mowed one. Rear discharge efficiently handles clippings without clumping or visible discharge trails, and the flip-up deck design provides fast, tool-free access to blades on all three decks for cleaning and maintenance. When paired with the Ventrac 4500 tractor on dual wheels, the combination is capable of mowing slopes up to 30 degrees in any direction — bringing contour mowing capability to terrain that would be unsafe or impossible with conventional equipment.

• Three Independently Floating Decks with 40-Degree Motion — each deck reacts to ground contour separately, maintaining consistent blade contact across all 83 inches of cutting width on slopes, swales, and transitions without scalping
• Full-Length Rear Rollers on All Three Decks — deliver consistent cut height, firm turf contact, and clean professional striping across every pass on every surface
• Out-Front Mount with Full Operator Visibility — all three decks remain in view at all times, enabling precise navigation around bunkers, cart paths, and course obstacles with confidence
