I'm Aaron Graber with Ventrac. In this video we'll talk about our line of
finished mower decks for the 4000 series tractor. The Ventrac 4000 series tractor
is well-suited for various types of mowing. We have a contour deck and a reel
mower that we sell mostly to golf and sports turf. We also have a tough cut
deck which handles rough mowing and field mowing.
We capture most other general-purpose mowing with our straight finished decks. These decks come in
60-inch side discharge 72 inch side and rear discharge and a 72 inch offset
model for better trim ability we also have mulch kits available as well as a
hydraulic easy lift option.
In this specific video the single deck that you're looking at is the MS 720.
Which is our 72 inch side discharge non offset model.
It's important to note that this deck also shares the same
characteristics and design features as the rest of the range.
We've engineered this line of finished decks to provide our customers with the best mowing
experience possible. The most powerful advantage of this system is the access
that it provides you you're able to climb Hills that most other equipment can't.
You're also able to operate this tractor and mower deck in wet conditions
or soft ground conditions where other equipment would get stuck or leave ruts.
Because of the articulated and oscillating frame you won't leave ruts
when you make tight turns with this tractor.
You can add dual wheels to allow
this combination to mow on steep hills up to 30 degrees.
The main features of these decks are that they have a 5 inch deep deck shell it's also smooth on the
underside so that it collects less grass and it maintains a consistent cut.
They also have 5 inch steel rear rollers to provide the best stripe possible a
single lever height adjust system for ease of adjustment and an offset front
left caster wheel for better trim ability.
Lastly the entire deck is a fully welded steel structur e with select components
being high-strength steel for added long-term durability.
All of these features add up to produce a deck that is both easy to use and produces great results.
The way these finished decks interact with the tractor is also very
important. First of all with the deck out front the operator has better visibility
they can see the corners of the deck so they can maneuver around things easier.
The deck also floats independently of the tractor to follow the contours of
the ground better and ultimately provide a better finished product
the third key component is serviceability having the deck out front
of the tractor makes easy to flip up and service as well as have access to change
belts or adjust certain things on the deck.
Lastly with the deck in front of
the tractor it's a very simple process to change from the mower deck to a
number of different attachments to connect to these finished decks all you
have to do is connect the hitch arms and the PTO belt.
If it has the optional hydraulic lift kit then you would also connect those
hydraulic lines to the auxiliary circuit on the tractor. When connecting to the
deck you want to make sure the cut height is in position number 18 this
will have the hitch arms at the proper height to make it easier to drive the
tractor into the attachment.
On the left side of the deck, you'll see the cut height adjustment.
It's a single lever, and it's super easy to do. You simply pull out,
select the position, and once you've selected the position, you pull up and lay the lever back down.
The sticker here has numbers 1-18 and they each have a corresponding cut height.
On this chart here, it will tell you what those values actually mean.
The cut height is adjustable from 1-5 inches.
So setting number 1 is a 1 inch cut height, and setting number 18 is a 5 inch cut height.
Those are quarter inch adjustments accept for the first 3 which are eighth inch adjustments.
To attach and detach from the mower deck you want to you want to set the cut height to the number 18 position.
Now we'll take a look inside the deck to show the position of some components.
You simply lift the hood and that will give you access. With the hood up you'll have
access to check and inspect your main drive belt it also gives you access to
the lever that releases drive belt tension right here. You'll release this
lever to either flip the deck up manually or to use your hydraulic flip-up kit.
The process to flip the deck up is the same initially remove the pin
from the drive belt tension and release the lever.
Then you release the left and right lockout pins.
Next you'll start the tractor and raise the deck
with the SDLA to the highest position. After that if you have the hydraulic
flip up kit you simply use the auxiliary lever on the SDLA to flip up the deck.
If you're flipping the deck manually you'll go to the front and lift the deck
and after that place the safety pins back in
As you can see, once you're in this position you have access to the underside of the deck.
This allows you to change or sharpen blades, service your spindles, or clean the deck.
We talked earlier about how the bottom side of it is made smooth so it accumulates less grass.
You can see that here.
This is all once surface.
There isn't as much grass buildup and the consistency of cut stays similar.
You'll also see some mounting holes in the baffles
This is where the mulch kit mounts to, if you decide to use one.
To lower the deck back down simply reverse the steps.
Also make sure you replace the pin before you use the deck of the next time.
There's three anti scalp rollers across the front of the deck.
If the cut height is two inches or higher, you want the position of these rollers to be in the lower hole.
If it's 1 and 3/4 inches or lower, you want the position in the upper hole.
When operating these mower decks, you'll want to always have the SDLA lever in the float position.
This allows the mower deck to have constant contact with the ground,
help prevent scalping, and provide the best quality of cut possible.
With weight transfer on maximum, you'll have the most traction possible.
If you take weight transfer entirely off, you'll have the boldest stripe.
Anywhere in between, and you'll have some mix between the two.
