The Degelman 7900 Series Bulldozer blades was developed specifically for producers moving silage, haylage and tackling the toughest snow removal jobs out there. Fully compatible with high horsepower four-wheel drive tractors, the 7900 has 40” lift and 6-way angling capabilities with full strength at all angles.

That means whether you’re at any angle you get the same industrial-sized strength that Degelman’s known for.

Move More Silage, Faster.

When you're working with silage, under-frame clearance is important. That's why at Degelman, our mounting system allows for extra under frame clearance. So you can pack and push more silage faster without getting hung up. We also make sure our mounting hardware gives you a smooth, clean underbelly to minimize dragging silage back. Add a two foot perforated silage extension, and you'll move more silage than ever.


Best Snow Removal Angle Ever

From our field testing, a 30° angle runs snow off the blade the best. That's why we made sure the 7900 can hit and hold 30° with optimal strength. This means faster and more efficient snow removal for any job out there.

Pure Power. At Your Fingertips

The 7900's controls give you the power and agility of angling control at your fingertips. There's no need to ever get out of your cab-ever. You can angle the blade from 0° to up to 24° (depending on tractor), lift up and down and tilt how you like, quickly and easily: The control stays where it belongs-with you.


Six-Way Blade Agility

When your blade can do can do more. Tilt. Angle. Lift. You name it. That's why the Degelman 7900 hydraulic system is designed for optimal blade angles and usage. Because we know your blade needs to take on all the jobs you tackle every day, not just some of them.

Tilt Away.

The fingertip-controlled tilt capabilities of the 7900 give you the option to tilt the blade up to 10°. So you can groom roads, put a ridgeline in for name it. And, because of our industrial-strength cylinders and heavy-duty design, you can doze with confidence knowing that our blade system can do the job, and then some.


Durable AR400 Skid Shoes.

Meet wear and tear head on. Our adjustable skid shoes are made with AR400 plate to give them a longer life with eight times the abrasion resistance of regular steel. We also precision designed them so you can easily ratchet them down by infinite intervals whether you're levelling a gravel yard...or compensating for slight wear on the blade, a Degelman first. Because more precision equals more blade control. These skid shoes are spoon-shaped for effective operation, turning and to reduce the chance of digging in. They are also reversible so when wear appears, you can easily rotate them.



Quick-Connect Coupler Option.

For added convenience, this optional quick-connect hydraulic coupler helps attach-detach the blade with even greater ease.

300-700 HP 7900 Hi-Lift Series

Developed specifically for producers moving silage and haylage, the 7900 can also take on the toughest snow removal jobs. With a lifting capacity of 40" - 60", a blade height of 47" tall, and an increased angle of 22° - 24° depending on tractor) to eliminate spillover, the 7900 is backed with over 40 years of blade experience.

Easy Bolt-On Assembly

Simple, Bolt-on brackets are all that is attached to your tractor. The rest of the assembly quickly attaches and detaches from these simple brackets. The brackets can also be removed if needed!

Common Components

Many of the 7900 blade assemblies use common components in different configurations. Here are some basic descriptions of some common components.


 HQT-Hydraulic Quick Tach System*

In the spirit of safety and simplicity, Degelman has pushed the design process one more time by coming up with the all new HQT-Hydraulic Quick Tach System. This precision built feature utilizes a hydraulic pin engagement concept which allows the operator to secure the blade to the Dozer mounting framework from the tractor seat. It avoids the dangers, awkwardness and hassles of crawling around the tractor to secure the dozer engagement. Just one more example of how Degelman pushes design to make things a little safer, more convenient and last longer.

*Not available for 4600 or 6600 model.

Quick-Attach D-Lock® Mounting

The D-Lock® mounting system offers the convenience of quick attach/detach as well as long life. No tools are required. Fit-ups are 100% secure with zero movement. The blade can be removed in minutes by disengaging two points on the front axle brackets.
