New for 2025
On-the-go, In-cab Automated Tillage Adjustments
Soil Command tillage technology comes standard on the 21-ft to 41-ft Speed-Tiller 475 models to automate all implement adjustments, on-the-go, from the comfort of the cab. Spend less time out of the cab physically making adjustments and more time getting field work done.
Leveling & Depth Control
A True Dual-Season Tool
The Speed-Tiller digs like a disk and finishes like a finisher for flexibility no matter the season. In fall, run deeper — from 3 to 6 inches — to manage crop residue, control weeds and destroy root balls. In spring, run at shallower depths to create an ideal seedbed finish.
Now available with Soil Control tillage technology to automate all adjustments from the comfort of the cab to conform to varying field conditions.
Depth Control
- Exclusive constant-level hitch mode delivers deep penetration, consistent disk depth and residue management
- Floating hitch mode easily follows the contours of the ground for optimized performance
- Puts usable weight on the blades to run deeper or transitions to roller wheel to optimize tool finish
- Wing down pressure provides consistent penetration and disk depth across the entire width to assure a high-efficiency seedbed
- Soil Command tillage technology maintains constant depth while automatically changing other settings to maintain consistent performance
Leveling
- Three conditioner attachment options provide the finish that fits each field: 16.5- and 19-inch diameter with 1.2-inch rifled round bar Crumbler roller
- 22-inch-diameter heavy-duty steel spring conditioner
- 21-inch-diameter rubber roller with mud scrapers
Blades
Designed to Work Your Entire Soil Profile
Laterally adjustable, indexed, independently mounted blades:
- Eliminate compacted valleys and humps where blades run below the soil surface
- Move more soil than traditional high-speed compact disks
- Unique blade position and design reduces plugging in wet soil conditions with high volumes of trash
- Rubber-torsioned disk arms, paired with the powerful leveling roller, effectively incorporate stubble into the soil
Operating Speed
Productivity at Your Speed
The Speed-Tiller high-speed disk is designed for superior agronomic performance at your speed, in your conditions. Reach high speeds with more robust disk mounts, arms and bearings, and a rugged frame built to withstand some of the world’s harshest soil conditions.
- 1.25-inch (32 mm) thick disk arms are the heaviest and strongest on the market, and nearly double the thickness of competitive units
- 5-bolt heavy duty disk bearings and hubs use unitized double taper roller bearings and a 7-lip cartridge seal for superior ruggedness and reliability
- Heavy-duty disk arm mount rubber torsions provide the needed down pressure to penetrate the hardest conditions with the needed protection in rocky soil conditions
- Hydraulically positioned conditioner roller allows the operator to lift the conditioner roller in muddy conditions
Performance & Design
Every Detail Counts
There are countless features that set the Speed-Tiller apart from the rest. When it comes to agronomic performance and promoting higher yields, every detail counts. Here are just a few reasons why the Speed-Tiller beats the competition every time.
Seedbed Finish
Boost Seedbed Quality From Floor to Surface
- Smooth seedbed floor contributes to consistent, accurate seed placement and uninhibited root development
- Unmatched agronomic performance maximizes weed control and water penetration for healthier soil
