Degelman Strawmaster 7000 Series: Specs & Reviews

The Degelman Strawmaster 7000 Series is the original, the machine that built the family’s reputation. It’s a tine-only heavy harrow focused on its core job — breaking up and spreading crop residue evenly — at meaningfully lower horsepower than the Pro, X or + . For operations whose priority is residue management and a clean seedbed rather than light tillage, the 7000 Series is the right-sized, cost-effective Strawmaster, and its lower power requirement opens it up to far more tractors than the big machines in the range.

Built in two tine configurations — a 5-bar and a 7-bar — across widths from 30 to 82 feet, it runs Degelman’s patented torsion spring-bar control and carbide Endura-Tip tines. The smallest 5-bar model needs only 100 horsepower minimum, putting it within reach of a mid-size tractor.

What the 7000 Series Is Built to Do

The primary purpose is straightforward: break up and spread most types of straw residue efficiently. High-frequency tine vibration shatters residue for clean, even distribution, and for most practices the machine runs at speeds up to 12 mph. Beyond residue spreading it rakes flax straw — it’s become one of the most popular machines for that job — controls weeds, levels lightly, and incorporates seed and chemical when paired with a granular applicator.

What it does not do, by design, is move significant soil. This is a residue and finishing harrow, not a light-tillage tool. That focus is exactly why it runs at lower horsepower than the rest of the family.

Choosing 5-Bar or 7-Bar

The bar count is the key decision and sets both finish quality and horsepower demand.

Configuration	Tine Size	Spacing	Character
5-bar	5/8 in x 26 in	18 in centers	Lighter, lower-horsepower, more economical — straightforward residue spreading
7-bar	1/2 in x 26 in	14 in centers	~68% more ground engagement, finer finish, better clod breakup — at higher horsepower

Choose the 5-bar for residue spreading on a tighter horsepower or budget. Choose the 7-bar when finish quality and thorough coverage justify the extra power.

Torsion Control, Contouring and Tines

Patented Torsion Spring-Bar Technology

The heart of every 7000 is the twin torsional spring-bar system, which lets the operator apply in-cab hydraulic down-pressure from zero up to 1,900 pounds per harrow section — or drop it into float when no pressure is needed. Rotating the 8-by-8 beam hydraulically lets the machine work the way conditions demand.

Ground Contouring

Under float or pressure, the sections flex independently. The torsion bars distribute pressure along the frame and let each section follow the contour — rising over hills, settling into hollows — so tine engagement stays even across rolling ground.

Carbide Endura-Tip Tines

Even on this lighter machine the standard carbide tips deliver roughly four times the life of standard harrow tines and help bust and move more straw as they hold their shape. Tine bars drop out with a few bolts for fast replacement.

Best Applications

The Strawmaster 7000 Series fits operations whose main need is residue shattered and spread evenly behind the combine, and especially those running mid-size tractors that can’t meet the horsepower demands of the Pro, X or + . The 5-bar SM30 in particular is the most attainable entry into Degelman heavy-harrow quality. It also suits flax growers, given its reputation for raking flax straw.

It’s not the right fit for operations wanting genuine light tillage or spring seedbed warm-up through soil movement — that’s the Strawmaster Pro’s and X’s territory.

How It Compares to Other Strawmaster Models

The 7000 is the residue specialist and the most accessible Strawmaster on horsepower and price. It doesn’t pretend to do light tillage — the Pro and X cover that. Against the Strawmaster + , the 7000 is the older, simpler, wider-transport platform; the + offers narrower transport and modern folding. For a residue and finishing job behind a tractor that isn’t a high-horsepower 4WD, the 7000 is very likely the correct Strawmaster, and the smaller widths are the only models in the family a mid-size tractor can run.

Frequently Asked Questions

How much horsepower does the Strawmaster 7000 need?

It spans a wide range: from 100 hp minimum on the smallest 5-bar SM30 up to 475 hp on the 7-bar SM82. The 5-bar models are the lower-horsepower options.

What’s the difference between 5-bar and 7-bar?

The 5-bar runs 5/8-inch tines on 18-inch spacing for lighter, lower-horsepower residue spreading; the 7-bar runs 1/2-inch tines on 14-inch spacing for about 68% more ground engagement and a finer finish at higher horsepower.

What sizes does the Strawmaster 7000 come in?

The 5-bar comes in 30, 50, 70 and 82 feet; the 7-bar in 50, 70 and 82 feet.

Can a mid-size tractor pull a Strawmaster 7000?

Yes — the 5-bar SM30 needs only 100 hp minimum, making it the one Strawmaster a mid-size tractor can realistically run. Larger and 7-bar models need substantially more.

Does the Strawmaster 7000 do light tillage?

No. It’s a tine-only residue and finishing harrow that spreads straw and lightly levels; it doesn’t move significant soil. For light tillage, the Strawmaster Pro or X is the tool.

How much down-pressure can it apply?

Up to 1,900 pounds per harrow section, applied hydraulically from the cab via the torsion spring-bar system, or set to float for no pressure.

Is the Strawmaster 7000 good for raking flax?

Yes. It’s become one of the most popular machines for raking flax straw, using spring-bar pressure to maximize holding capacity.

How fast can the Strawmaster 7000 run?

For most farming practices, speeds of up to 12 mph can be attained.

What’s the transport width?

14 feet 7 inches across both the 5-bar and 7-bar configurations.

Do the carbide tines really last longer?

Yes. The carbide Endura-Tip tines deliver roughly four times the life of standard harrow tines and hold their shape as they wear, helping move more straw over the life of the machine.
