Electric Motor vs. Diesel Engine Forage Cutting Machine
The TZ-420 is available with electric motor and diesel engine power options. The right choice depends mainly on the farm’s electricity supply, operating environment, and daily processing requirements.
Electric Motor Model for Farms with Stable Power
The electric model is suitable for farms and feed preparation facilities with a reliable electricity supply. It uses a 3 kW electric motor, offering a straightforward option for routine forage cutting and dry corn crushing.
Key considerations include:
- Convenient operation where electricity is readily available.
- No diesel fuel required to power the machine.
- Suitable for farms with a fixed processing area.
- Requires an appropriate electrical supply and safe wiring.
Diesel Engine Model for Areas Without Reliable Electricity
The diesel model is an alternative for farms where grid electricity is unavailable, unstable, or inconvenient to access. It can be considered for remote livestock operations and agricultural locations that need an independent power source.


Three Sieve Options for Different Processing Needs
The TZ-420 is supplied with three processing configurations: a 3 mm sieve, an 8 mm sieve, and a configuration for straw cutting. Each serves a different processing purpose.
3 mm Sieve for Fine Corn Powder
The 3 mm sieve is intended for producing finer corn powder. This configuration may suit farms that need finely crushed corn for mixing with other feed ingredients.
8 mm Sieve for Coarse Corn Grits and Grass Powder
The 8 mm sieve is intended for coarser corn grits and grass powder. It is an option for users who do not require the same degree of fineness as the 3 mm configuration.
Straw Cutting Without a Sieve
A separate configuration is available for cutting straw without using the grain-crushing sieve. This allows the machine to be used for forage preparation rather than fine grinding.

Applications of the TZ-420 Forage Cutting Machine in Livestock Farming
Preparing Chopped Grass for Cattle and Sheep
Livestock farms can use the forage cutting function to prepare suitable grass and straw for daily feeding. Chopped forage is easier to handle and distribute, particularly where workers prepare feed for multiple animals.
Crushing Dry Corn for Feed Preparation
Depending on the screen selected, dry corn can be ground into fine powder or coarse particles. For farms that prepare their own feed, this equipment can be used in conjunction with a feed pellet mill.
Processing Straw and Other Crop Residues
Suitable straw and crop residues can be processed for use in feed preparation or other farm applications, depending on the material and intended purpose.
