https://www.ventrac.com/ When it comes to maintaining an elite property, a trusted and specialized mowing deck is essential to creating that polished look to a landscape.
Ventrac’s Contour Mower is built for precision mowing on golf courses and resorts that have challenging terrain but also require professional results.
It is unique in a way that three decks float independently and follow the contour of the terrain with up to 40 degrees of motion for each side deck. This ensures the best possible quality of cut while minimizing the scalping of the surface.
The combination of Contour Deck and Ventrac 4500 tractor with dual wheels allows mowing of up to 30 degrees in any direction without destroying turf and keeping operator safety in mind.
The total cut width of the Contour Deck is 83 inches with a rear discharge for clean results in an efficient manner. The deck also features full rear rollers for even cutting and striping to create a finished look that is expected from such an implement.
When it comes time to clean the deck or service the blades, it couldn’t be easier with the quick, flip-up deck design. Easy access to the deck for servicing can be done by one person in less than a minute.

The contour mower is a rear discharge and has a total cut width of 83-inches there are a total of six 15 inch blades - on each deck which are counter rotating to provide the best discharge possible. This is our mower deck with the widest cut width. It's not necessarily suited for rough applications or larger acreage where a tough cut or maybe a finish mower would be a better solution. This deck is built for precision mowing which means golf courses or other high-end properties only. The contour mower attaches to the tractor with the front hitch arms the belt driven PTO and the two standard hydraulics. The contour deck has a cut height range between three-quarters of an inch and three and a half inches and quarter inch increments. To change the cut height settings refer to this graphic and select your cut height. It'll show you where you need to locate the front caster wheels. The anti-scalp wheels and the rear roller brackets on each individual deck both the left and right side caster wheels can be located in an outer or an inner position to change the characteristics of the deck. If it's located in the outermost position, it provides the most stability and consistent quality of cut and on the inner position, it provides the best overhang. If you're doing bunkers or something else that can be changed loosening these two bolts in the front and the one bolt in the back moving this whole thing over and then retightening those three bolts. Flipping the contour deck up is an easy process that takes less than a minute. The first step is to use the SDLA lever to raise the attachment all the way and to raise the left and right side decks to their highest position. You can grab the front of the deck and then pull the release lever in the back and flip the entire thing up. The contour mower also has a mulch kit available for it. It would be bolted here and here on each individual deck to lower the deck simply put pressure on the front and pull the release mechanism then once it's down make sure you return the belt tension spring to its upper setting with the deck in this position. It's a good opportunity to show the movement of the side pods both up and down and front to back for a 40 degree total range of motion on each side. The rear SDLA lever controls this link which either allows the right and left decks to float all the way down or up or if it draws inward it pulls the decks up for transport position. It's important that when you're operating you have this gap here so that both of the decks can fall away from the center deck and actually contour down. This can be accomplished with an optional spool valve kit to allow you to place the secondary SDLA lever in float or you can set this position manually. It's recommended to have a weight transfer setting of 3 or 4 depending on your conditions but having it in 4 can sometimes cause the center deck to rise up over contours too much so pay attention and if you're missing grass lower the weight transfer setting to 2 or 3.
