Degelman Strawmaster Pro: Specs, Reviews & Buyer’s Guide

The Degelman Strawmaster Pro is the heaviest and most aggressive harrow in the Strawmaster family, and the one model that genuinely blurs the line between residue management and light tillage. Where a conventional drag harrow only combs and spreads straw across the surface, the Strawmaster Pro is built to push its 30-inch carbide tines into the soil profile, move dirt, blacken the field and warm the seedbed in spring. For prairie operations chasing earlier germination on heavy, cold, high-residue ground, that capability is the whole reason the machine exists.

Built in three working widths from 80 to 120 feet, the Pro sits at the top of the tine-only Strawmaster range. It runs on Degelman’s Hydralink contouring frame, carries hydraulic down-pressure adjustable from the cab, and uses sealed maintenance-free bushings so there’s no daily greasing during the short spring and fall work windows.

Residue Harrow or Light Tillage?

The Strawmaster Pro is positioned as a dual-purpose tool: heavy residue harrowing on one end of the dial, light tillage on the other. The mechanism that makes that possible is the Hydralink frame, which transfers machine weight onto each individual tine and sinks them into the ground rather than floating them across the top.

In float position, the Pro behaves like a high-capacity residue harrow — shattering and spreading straw, raking flax, controlling early weeds and leveling light ruts. Under hydraulic down-pressure, it starts working soil, sizing and incorporating residue and turning over enough black dirt to speed spring warm-up. That spring warm-up is the practical headline for the prairie: cold, residue-covered soil delays germination, and a short growing season punishes every lost day. A pass under pressure exposes darker soil, dries the surface and brings seedbeds to temperature sooner — without the disturbance, moisture loss or erosion exposure of full inversion tillage.

Key Specifications

The Pro is offered in three working widths. All three share the same frame architecture, tine specification and hydraulic package — the differences are width, weight, section count and the horsepower needed to run them at field speed.

Tines, Frame and Build Detail

30-Inch Carbide Endura-Tip Tines

The Pro runs 5/8-inch by 30-inch tines tipped with tungsten carbide. The carbide tip is the single most important wear component on any heavy harrow, because a tine that wears short loses both reach and aggressiveness. Degelman’s square carbide tips hold their length and shape far longer than standard round steel tips, with tines reported still measuring near full length after 100,000-plus acres. For a high-acre operation that translates into consistent field finish over the life of the machine and fewer tine changes.

Hydralink Contouring Frame

The four-row sections flex independently. Spring bars positioned along the frame sides distribute pressure evenly and let each section rise over knolls and drop into hollows, so tine engagement stays consistent across rolling ground rather than digging on high spots and skipping low ones. This contouring is what allows the Pro to run light-tillage down-pressure without gouging on uneven terrain.

Maintenance-Free Bushings

The pivot points use self-lubricating sealed bushings on oversized 2-inch nickel-plated pins. The practical payoff is no daily greasing during the short, unforgiving spring and fall work windows — drop the pin and go.

Horsepower and Field Fit

The Pro is a high-horsepower machine. The SMP80 wants 400 hp minimum and runs best around 440 hp; the SMP120 needs 560 hp minimum and ideally 620-plus. These are numbers for a high-horsepower 4WD or articulated tractor of the kind a large grain operation already runs for seeding and primary tillage. If available horsepower sits below the minimum for a given width, stepping down to the next narrower model is the better choice, because the Pro only delivers its light-tillage benefit when it can carry tines at depth at working speed.

Best Applications

The Strawmaster Pro fits best on large prairie grain operations dealing with heavy fall residue and cold, slow-warming seedbeds, where the goal is to spread straw and warm the soil for earlier spring germination across big acres. It suits operations already running high-horsepower tractors and looking for a single tool to handle residue and light tillage in one pass.

It is not the right fit for smaller acreages, operations with mid-size tractors that can’t meet the horsepower minimums, or buyers who only need residue spreading without soil movement — in those cases the lighter, lower-horsepower Strawmaster 7000 Series is the more sensible match.

How It Compares to Other Strawmaster Models

The Pro is the aggressive end of the tine-only range. The classic Strawmaster 7000 Series is a lighter, lower-horsepower residue harrow built for combing and spreading rather than moving soil. The Strawmaster X adds a row of discs ahead of Pro-style tines for more cutting and blackening than the Pro alone. The Strawmaster + is the customizable middle ground, offered in 4, 5 or 7 rows. If the priority is genuine light tillage and spring soil warm-up across big acres, the Pro is the pick; for residue spreading at lower horsepower, the 7000 Series is the smarter spend.

Frequently Asked Questions

Is the Strawmaster Pro a harrow or a tillage tool?

Both, by design. In float it works as a heavy residue harrow; under hydraulic down-pressure its 30-inch tines sink into the soil to perform light tillage, moving dirt and warming the seedbed.

How much horsepower does the Strawmaster Pro need?

From 400 hp minimum on the 80-foot SMP80 up to 560 hp minimum on the 120-foot SMP120, with ideal horsepower ranging from 440 to 620-plus depending on width.

What sizes does the Strawmaster Pro come in?

Three working widths: 80 feet (SMP80), 100 feet (SMP100) and 120 feet (SMP120).

What makes the carbide Endura-Tip tines different?

The tungsten carbide tips hold their length and shape far longer than standard steel tips, maintaining consistent field finish and reach over the life of the machine — Degelman reports tines near full length after 100,000-plus acres.

Does the Strawmaster Pro require daily greasing?

No. It uses self-lubricating sealed bushings on oversized 2-inch nickel-plated pins, so there’s no daily grease routine during the spring and fall work windows.

How does the Pro warm up the seedbed?

Under down-pressure the tines move soil and expose darker dirt, which absorbs more heat and dries faster, bringing the seedbed to germination temperature sooner in a short prairie spring.

Can the Strawmaster Pro incorporate seed and chemical?

Yes. Paired with a granular applicator it spreads and incorporates surface-applied seed and granular chemical while it works residue.

How does the Pro differ from the Strawmaster X?

The Pro relies on tine down-pressure alone; the X adds a front row of adjustable discs for actual cutting and more soil blackening, sitting between a harrow and a high-speed disc.

Is the Strawmaster Pro good for rolling ground?

Yes. The Hydralink contouring frame lets each section flex independently, following hills and hollows so tine engagement stays even across uneven terrain.

What’s the transport width of the Strawmaster Pro?

18 feet across all three models, with transport length running from about 64 to 84 feet depending on width.
