Degelman Strawmaster + : Specs, Row Options & Reviews

The Degelman Strawmaster + is the configurable member of the Strawmaster family. Rather than locking a buyer into one tine layout, it’s offered in 4, 5 or 7 rows, so the machine can be dialed toward aggressive light tillage or toward a finer finishing pass depending on how it’s specced. Built on a 10-by-10 wing-beam frame with a narrow 12-foot-6 transport width, it’s designed to be both a capable field conditioner and an easy machine to move between fields during the short prairie work windows.

Available in 70 and 90-foot working widths, the + carries the same maintenance-free bushings and carbide Endura-Tip tines as the rest of the range, with the row count as the defining choice.

Choosing the Row Configuration

The row choice is the defining decision on this machine, because it sets the machine’s whole character — more rows mean more ground engagement and a finer finish; fewer rows with longer tines mean more reach and a more tillage-oriented pass.

Configuration	Tine Size	Character
4-row	5/8 in x 30 in	Longest, most aggressive — near-Pro behaviour, best for moving soil and light tillage
5-row	5/8 in x 26 in	Balanced engagement and finish — the general-purpose middle choice
7-row	1/2 in x 26 in	Most ground engagement, finest finish — mid-duty conditioning on the heavy-duty frame

Transport, Adjustment and Build Detail

Narrow Transport and Easy Folding

The + carries a 12-foot-6 transport width — narrower than Degelman’s earlier Strawmaster series — and a redesigned inboard transport and wing-wheel assembly that makes folding in and out of transport quick and lets the machine follow the tractor more closely into narrow field approaches. On a wide harrow, transport practicality determines how many fields can realistically be hit in a day.

Three Setting Indicators

The + has visible indicators for cart height, beam torsion and tine angle, so the operator can set a repeatable configuration and return to it field after field. Re-phasing cylinders deliver increased power for tine-angle adjustment when conditions get tough.

Maintenance-Free Bushings

The + uses the same sealed, self-lubricating bushings on oversized 2-inch nickel-plated pins as the Pro — no grease gun required during the spring and fall crunch.

Horsepower and Field Fit

Horsepower demand is 400 hp minimum on the SM+70 and 500 hp on the SM+90. The heavier row configurations add weight and therefore draft, so a 7-row 90-foot machine pulls harder than a 4-row of the same width. Match the row choice and width to the tractor that will actually go in front of it.

Best Applications

The Strawmaster + fits a buyer who knows they want a Degelman heavy harrow but isn’t certain how aggressive a setup their operation needs. Specced as a 4-row it handles near-Pro light tillage; specced as a 7-row it becomes a fine finishing conditioner. It suits high-horsepower operations that value the narrow transport and modern folding for moving across many fields in a short window.

It’s not the right fit for operations under roughly 400 horsepower, or for those who specifically need a disc row for cutting heavy trash — the Strawmaster X is the better answer there.

How It Compares to Other Strawmaster Models

The + is the flexibility play. Specced as a 4-row, it overlaps heavily with the Strawmaster Pro’s aggressive 30-inch-tine behaviour; specced as a 7-row, it becomes a finishing conditioner closer to the classic Strawmaster 7000’s role but on a heavier frame. The Strawmaster X is the choice when discs are needed for cutting; the + stays tine-only. For a buyer undecided about how aggressive a harrow they need, the + settles it with the row spec rather than the model choice.

Frequently Asked Questions

What does the “+” mean on the Strawmaster + ?

It refers to the customizable design — the machine can be ordered in 4, 5 or 7 rows to tune aggressiveness and finish to the operation’s needs.

What’s the difference between the 4, 5 and 7-row setups?

The 4-row runs the longest 30-inch tines for the most aggressive, tillage-oriented pass; the 5-row balances engagement and finish; the 7-row offers the most ground engagement and finest finish at higher horsepower cost.

How much horsepower does the Strawmaster + need?

400 hp minimum on the 70-foot SM+70 and 500 hp on the 90-foot SM+90, with ideal horsepower of 450 and 550.

What sizes does the Strawmaster + come in?

Two working widths: 70 feet (SM+70) and 90 feet (SM+90).

How does the + differ from the Strawmaster Pro?

The Pro is fixed at 4 rows of 30-inch tines with Hydralink down-pressure for light tillage; the + offers a choice of 4, 5 or 7 rows, letting it range from near-Pro aggressiveness to a finer finishing conditioner.

Is the Strawmaster + easy to transport?

Yes. It folds to a narrow 12-foot-6 transport width with a redesigned wing-wheel assembly that follows the tractor closely into narrow approaches.

Does the row choice affect how hard it pulls?

Yes. More rows add weight and draft, so a 7-row machine pulls harder than a 4-row of the same width — factor that into the tractor match.

Does the Strawmaster + need daily greasing?

No. It uses sealed self-lubricating bushings on oversized 2-inch nickel-plated pins.

Which row configuration is most popular?

There’s no single answer — it depends on whether the operation leans toward light tillage (4-row) or fine residue finishing (7-row), with the 5-row as the balanced general-purpose choice.

Can the Strawmaster + do light tillage?

In the 4-row configuration with its 30-inch tines, yes — it approaches the Strawmaster Pro’s soil-moving capability.
