| DIFFERENT BLADE TYPES COMPARISON | ||
| There are four types of blades (Twisted, Flat, Stepped and Angled) | ||
| 1. | TWISTED BLADES: Two fitted per rotor (preferred in 85 percent of areas). 3.9m (13') to 5.4m (18') machines will be fitted with the more popular twisted blades, unless ordered otherwise. | |
| Advantages: | ||
| a. | Generally cleaner cut and better windrow | |
| b. | More ground clearance of rotor plates (compared to flat blades) | |
| c. | Generally less horsepower to drive than flat blades | |
| d. | Slightly better protection of blade bolt head from wear (compared to flat blades) | |
| e. | Retains a reasonable cutting edge (compared to other blade types) | |
| Disadvantages: | ||
| a. | Not reversible - they are either clockwise or anticlockwise. Care must be taken to put clockwise blades on clockwise rotors and vice versa. | |
| b. | If one blade is lost (1 out of 2), severe vibration can cause more damage more quickly. | |
| 2. | FLAT BLADES: Four fitted per rotor (will operate with two per rotor) | |
| Advantages: | ||
| a. | Reversible rotation | |
| b. | If one out of four blades is lost, less vibration than one out of two | |
| Disadvantages: | ||
| a. | Generally require more horsepower to drive than twisted blades | |
| b. | Generally not as clean cut, or as good a windrow | |
| c. | More wear on blade bolt heads | |
| 3. | STEPPED BLADES: Two or four per rotor |
| a. | Two stepped blades are fitted on 6.4m - 9.45m (21' - 31') machines as standard for general purpose cutting. | |
| b. | Stepped blades can be fitted four per rotor (two stepped up and two down). Used for more of a mulching effect with minimal rowing. | |
| c. | Four stepped blades are an extra cost option when ordered with new machine. |
| 4. | ANGLE BLADES: Two fitted along with two stepped blades per rotor |
| a. | Generally better mulching and spreading action | |
| b. | Extra cost option when ordered with new machine |
