Something to rely on

Simple, reliable, all-purpose: such are the terms applied by farmers across the globe to the Strawmaster 7000 wide grip, spiked tooth harrow from the Canadian Company Degelman. AgroCentre specialists believe that this unique product of North American designers has shown itself to advantage on Russian fields. Today an increasing number of farmers are showing an interest in this tool.

Featuring a grip width of 9 to 25 m, the Strawmaster crushes and distributes straw after harvesting, destroys weeds, rakes up and introduces chemicals and seeds. It ideally prepares the soil for subsequent seeding by the no-till or minimal till technology. The machine’s operating speed may reach 20 km/h.

The basis of the tool is a simple metallic frame fitted with torsion spring-aided rods (teeth). Arranged along the lateral edges of the harrow frame, they ensure an even distribution of the workload up to 862 kg per section. The rods closely follow the field profile, raising the frame at elevations and lowering it in depressions, thereby enabling the tool “to hug the ground.” Furthermore, the spring-aided rods support the entire harrow in transportation. 

The teeth in four or five rows are put on large sections (3.05 m wide, 1.83 m long) at a distance of 0.61 m from one another in order to maximise the amount of material going through them. The teeth are shaped like conical springs, which reduce the stress on metal and prevents tooth breakage.

Hydraulic cylinders replace a conventional gear-drive jack. They help to synchronise the setting of the harrow inclination angle and ensure steady pressure on each section. 

Thanks to rigid cross bars, the Strawmaster is remarkably manoeuvrable, ensuring rearward movement control on the field and during sharp turns.

Offered for the harrow as an option is the Valmar 3255 system for introducing granulated fertilisers and seeds.

Customers of AgroCentreZakharovo Company, Penza oblast, share their experience of using the Strawmaster harrow

Ismail Gabayev, SverdlovskAgro LLC deputy director general: 

“Last year we bought seven Strawmaster harrows for our farms all at once. We took a long time making our selection, considered different versions and finally opted for the Canadian manufacturer. And we never once regretted it! We’re genuinely thankful to AgroCentre for this. We use the harrows mainly for closing moisture in early spring. The tool destroys weeds and treats the soil without drying it. The result is excellent! In a day, one harrow, pulled by a 375 hp tractor, tills around 300 ha at a rate of 10-15 km/h. It is easy to fold it to 4.5-m transportation width and to bring it onto any field. In my opinion, this machine is one of our luckiest investments!”

Andrey Morunkov, Penza Zolotaya Niva LLC chief engineer:

“We’ve been using the Strawmaster 7000 harrow since 2008. This is a highly efficient wide grip tool of premium quality. Today, 7 harrows, each with a grip width of 24 m, till an area of 45,000 ha. They do the job easily within a week, less the ferry time. In spring, the harrow closes in the moisture perfectly, smooths out the field, and prepares the soil for seeding. The adjustable treatment depth enables us to independently adjust the tool. As a rule, we harrow at a depth of 3 to 5 cm. All the main units are durable and reliable; the teeth are made from high quality spring steel. Not a single serious malfunction occurred in 5 years of operation, except a slight wear of welding seams. This is a perfect harrow for large tilling areas.  We like it and recommend it to everyone!”
