The Complete Wood Chipper Buyer's Guide for NZ Farms – 2026
Whether you're clearing land, processing pruning waste, or maintaining an orchard, a wood chipper can save time and effort. But with different models, power ratings, and features available, choosing the right one for your needs can be challenging. This guide covers everything you need to know to make an informed decision.
What Is a PTO Wood Chipper?
A PTO (Power Take-Off) wood chipper is a tractor-mounted implement that processes branches, logs, and wood waste into manageable wood chips. Unlike self-powered or electric chippers, PTO models draw power directly from your tractor, making them ideal for professional use and high-volume work on farms and properties.
PTO wood chippers feature:
- 3-point linkage for easy attachment and removal
- Direct power from your tractor's PTO shaft
- No additional engine or electricity required
- Efficient chipping and discharge capabilities
- Durability for heavy-duty farm work
- Can be moved where ever your tractor can go.

Why Choose a PTO Wood Chipper Over Other Options?
vs. Self-Powered Chippers
Self-powered chippers require their own engines, are harder to transport, and cost more to maintain. Tractor-mounted PTO chippers use power you already have available from your tractor reducing your investment and operational costs.
Key Features to Consider
Capacity & Throughput
Wood chipper capacity is measured in two ways:
- Feed Diameter: The maximum branch thickness the chipper can handle (typically 75–130mm for farm models)
- Hourly Output: How much material the chipper processes per hour (measured in cubic meters)
Choose based on your typical material size and volume. Larger branches and higher volume require larger capacity models. Most people consider any branches over 4-5 inches as firewood. Check out the Sierra Log Saw for processing larger branches into Firewood efficiently
Power Requirements
PTO wood chippers can be used on 15–100 HP tractors, depending on the model. Always match the chipper's power rating to your tractor to avoid overloading. Higher HP tractors allow more aggressive chipping and faster processing some wood chippers have protection from overloading like shearbolt PTO shafts
Cutting Mechanism
Most farm wood chippers use one of two designs:
- Flywheel with Knives: Fast, efficient cutting with replaceable hardened steel blades. Ideal for consistent chip size and longer service life.
- Drum Style: More aggressive cutting, better for tougher material. Less common in farm-scale models.
Discharge Options
Look for models with:
- Adjustable discharge height for directing chips into trailers
- Bidirectional discharge to switch direction without moving equipment
- Elevation control to angle chips away from the operator
Choosing the Right Model for Your Situation
Small Farms & Lifestyle Blocks (15–40 HP Tractors)
Suitable for: Pruning maintenance, small clearing jobs, light orchard work
Look for:
- Lighter frame (easier on small tractors)
- Feed diameter 75–100mm
- Hourly output 3–6 m³
- Compact dimensions to fit through gates and tight spaces
Medium to Large Farms (40–65 HP Tractors)
Suitable for: Regular land clearing, orchard maintenance, professional landscaping work
Look for:
- Reinforced frame for heavy-duty use
- Feed diameter 100–130mm
- Hourly output 6–10 m³
- Standard 3-point linkage compatibility
Large Farms & Professional Contractors (65–100 HP Tractors)
Suitable for: High-volume processing, commercial land clearing, large-scale waste management
Look for:
- Heavy-duty construction with reinforced components
- Maximum feed diameter and output capacity
- Hydraulic features for specialized applications
- Advanced safety systems and operator protection
PTO Shaft & Gearbox Considerations
The PTO shaft and gearbox are critical components:
- Shear Bolt Protection: Protects your tractor's driveline if the chipper encounters a hard object. Essential safety feature.
- Gearbox Ratio: Affects cutting speed and torque. Higher ratios (2:1 or 3:1) provide more cutting force for tougher materials.
- Shaft Speed : Standard PTO shafts are 540 RPM; The Hanmey WCX5 can operate at 540-1000RPM as it is direct drive, How ever the Mateng is already got a step up gearbox in it runs on 540 RPM only
Discharge Hood & Chute Management
The discharge system is crucial for safe, efficient operation:
- Adjustable Height: Direct chips at the correct angle into trailers or away from bystanders
- Rotation Options: Bidirectional discharge (0°/180°) allows direction changes without repositioning the implement
- Hood Design: A properly designed discharge hood keeps chips contained and directs them safely
Maintenance & Operating Costs
Regular Maintenance
- Check and replace cutting blades annually or as needed
- Monitor gearbox oil levels and quality
- Inspect the PTO shaft for wear and damage
- Clean the discharge chute to prevent material buildup
Blade Replacement
Hardened steel cutting tips are replaceable and relatively inexpensive. Regular replacement ensures consistent performance and chip quality. Quality brands offer standardized replacement tips to reduce downtime.
Operating Tips to Reduce Costs
- Feed material steadily (don't overload)
- Clear blockages immediately to avoid damage
- Maintain proper tractor RPM for optimal performance
- Store the chipper under cover during off-season
Safety Considerations
- Operator Training: Ensure the operator understands the chipper and tractor controls before operation
- Shear Bolt Protection: A functioning shear bolt protects both the chipper and tractor from damage
- Discharge Guard: Always engage the discharge guard to direct chips safely
- Maintenance: Never attempt maintenance or cleaning while the PTO is running
- Personal Protective Equipment: Wear safety glasses, hearing protection, and appropriate clothing
Frequently Asked Questions
Q: What size wood chipper do I need?
A: Match the chipper's power rating to your tractor. A 15–40 HP tractor suits compact models; 40–65 HP tractors work with medium models; 65+ HP tractors can handle heavy-duty units. Consider your typical branch size and processing volume some smaller tractors. under 25 HP may not be able to maintain maximum cutting size of the chipper.
Q: How often should I replace the cutting blades?
A: Hardened steel blades typically last 50–100 hours of use, depending on material density. Replace when chips become uneven or the chipper slows down its self feeding ability .
Q: Is PTO better than Petrol engine for wood chippers?
A: PTO is the standard for most farm chippers. It's simple, reliable, and cost-effective. Petrol engine options are usually for smaller backyard operations with smaller volumes to deal with they generally won't deal with larger longer branches
Q: Can I chip wet or green wood?
A: Yes, but it's harder on the equipment. Wet wood is denser and wears blades faster. Allow freshly cut wood to dry slightly before chipping when possible.
