1. Hustler Super Z: Best for Steep Slopes
The Hustler Super Z is our top pick for steep hillsides, thanks to its powerful 35 hp Kawasaki engine and heavy-duty frame that keeps it planted on grades up to 25 degrees. Owner feedback consistently praises its traction on slopes, and the dual hydrostatic pumps allow precise speed control. The ROPS and seat belt add a layer of safety, though operators should still exercise caution on extreme inclines.
However, the Super Z’s 1200-pound curb weight can leave ruts on delicate lawns, especially after rain. It is also overkill for smaller properties with gentle slopes. Skip this mower if you need to maneuver in tight spaces or have a primarily flat yard, as its size and weight become drawbacks.
- High-torque engine and heavy frame provide excellent traction on steep inclines
- Dual hydrostatic pumps deliver smooth, responsive control on uneven terrain
- Operator presence system and rollover protection structure (ROPS) enhance safety
Pros: Exceptional hill-climbing ability due to low center of gravity and aggressive tire tread; Commercial-grade durability with reinforced steel frame and sealed bearings
Cons: Heavy weight can cause turf damage on soft or wet hillsides
2. John Deere Z950R: Premium Hill Climber
The John Deere Z950R is a premium choice for hillsides, with a 24 hp Yanmar diesel engine that delivers consistent torque for climbing. Its heavy-duty frame and wide stance provide stability, and the folding ROPS is a practical feature for low-clearance storage. Owners report that the mower handles 15-degree slopes with ease, and the suspension seat makes long mowing sessions comfortable.
On the downside, the diesel engine’s noise level may be bothersome in residential areas, and cold starts can be sluggish. The Z950R is also expensive, making it a better fit for commercial use or large estates. If you have a modest yard or prefer gas engines, consider a lighter model.
- Diesel engine provides high torque for maintaining speed on inclines
- High-back suspension seat and ergonomic controls reduce operator fatigue
- ROPS folds for storage, but must be raised on slopes for safety
Pros: Excellent fuel efficiency and long engine life ideal for large properties; Smooth, precise steering even on uneven terrain
Cons: Diesel engine is noisier and requires more maintenance than gas
3. Bad Boy ZT Elite: Best Value for Hills
The Bad Boy ZT Elite offers strong value for hillside mowing, with a 24 hp Kohler engine and aggressive tires that grip well on slopes up to 15 degrees. The 7-gauge steel deck and frame are built to last, and owners appreciate the straightforward maintenance. In our evaluation, it performs reliably on moderate inclines without breaking the bank.
However, the ZT Elite’s deck can scalp on bumpy terrain, requiring careful height adjustment. It also lacks a ROPS, so safety on steep hills is a concern. Skip this mower if your property has very steep slopes or if you prioritize safety features; consider a model with rollover protection instead.
- Aggressive tread tires provide good grip on moderate slopes
- Heavy-duty 7-gauge steel frame withstands rough terrain
- Intuitive controls with adjustable lap bars for comfort
Pros: Affordable price point for the build quality and hill performance; Easy to service with accessible components
Cons: Deck can scalp on uneven ground if not adjusted properly
4. Gravely ZT HD 60: Best for Uneven Terrain
The Gravely ZT HD 60 is designed for rough, uneven hillsides, with a wide stance and low center of gravity that keep it stable. The suspension seat and large tires smooth out bumps, and the 24 hp Kawasaki engine provides enough power for moderate climbs. Owner feedback highlights its durability on rocky terrain and its ability to maintain traction on loose soil.
However, the slow reverse speed can be frustrating when repositioning on a slope, and the mower is on the heavier side. It is not ideal for small, flat lawns where agility is more important. If you have very steep, smooth hills, a lighter model might be better.
- Extra-wide stance and low center of gravity enhance stability on slopes
- Dual-link suspension seat absorbs bumps from uneven terrain
- High-back tires with deep tread provide traction on loose soil
Pros: Excels on bumpy, uneven hillsides with excellent suspension; Durable construction with reinforced frame and cast iron spindles
Cons: Reverse speed is slow, making maneuvering on slopes tricky
5. Cub Cadet Ultima ZT1 50: Best for Gentle Slopes
The Cub Cadet Ultima ZT1 50 is a solid choice for gentle slopes up to 10 degrees, with a 23 hp engine and a lighter frame that reduces turf damage. It offers a comfortable ride and straightforward controls, making it popular among homeowners. In our research, it performs well on mild inclines but struggles on steeper terrain where traction is lost.
This mower lacks the power and stability for steep hillsides, and the absence of a ROPS is a safety concern on any slope. Skip it if your property has significant hills; consider a heavier-duty model for better grip and safety.
- Compact size and lighter weight make it easier to handle on moderate slopes
- Steering wheel steering option reduces fatigue on long mows
- Electric PTO and easy deck lift for convenience
Pros: Good value for homeowners with gently sloping lawns; Easy to operate with intuitive controls and smooth turning
Cons: Not suitable for steep hills due to limited traction and stability
6. Ariens Edge 48: Compact Hill Mower
The Ariens Edge 48 is a compact zero turn mower suitable for small properties with gentle hills. Its 20 hp engine and lightweight frame make it easy to maneuver, but it lacks the torque to climb steep slopes reliably. Owner feedback indicates it works well on flat to slightly rolling terrain, but struggles on grades over 10 degrees.
Safety is a concern on hills due to the light weight and lack of rollover protection. This mower is best for flat or mild hills where agility is more important than raw power. If you have steep hills, look for a heavier model with more traction.
- Compact footprint fits through tight gates and around obstacles
- Lightweight design reduces soil compaction on hillsides
- Easy-to-read fuel gauge and hour meter
Pros: Maneuverable in small yards with gentle slopes; Affordable entry-level zero turn for hills
Cons: Underpowered for steep or long inclines
7. Swisher ZTR 60: Budget-Friendly Option
The Swisher ZTR 60 is a budget-friendly zero turn mower that offers a wide deck for flat properties, but it is not designed for hillsides. Owner feedback reports frequent wheel spin on slopes, and the lightweight frame lacks stability. In our evaluation, it is best suited for flat, open lawns where speed and deck size matter.
Safety is a major concern on hills due to the lack of traction and no ROPS. This mower should be avoided on any incline. If you have hills, invest in a model with better tires and a lower center of gravity.
- Large deck covers more ground quickly on gentle slopes
- Synthetic deck resists rust and reduces weight
- Adjustable seat and cup holder for basic comfort
Pros: Lowest price point for a full-size zero turn deck; Wide cutting width for efficiency
Cons: Poor traction on hills; wheels spin on damp grass
Frequently Asked Questions
What should I look for in a zero turn mower for hillsides?
Focus on traction, stability, and safety features. Look for aggressive tread tires, a low center of gravity, and a heavy frame. ROPS (rollover protection structure) and a seat belt are essential for steep slopes. Also consider engine torque and hydrostatic transmission for consistent power on inclines.
Can zero turn mowers handle steep hills?
Some zero turn mowers can handle slopes up to 15-20 degrees, but performance varies. Models with heavy frames, wide stances, and high-torque engines perform best. Always check the manufacturer’s recommended slope rating and never exceed it. For very steep hills, a track-drive mower might be safer.
Is ROPS necessary for mowing hills?
Yes, ROPS is critical for hillside safety. In the event of a tip-over, ROPS and a seat belt can prevent serious injury. Many commercial-grade mowers include ROPS, but some residential models do not. If you mow slopes, prioritize models with ROPS or add an aftermarket kit.
How do I prevent scalping on uneven hillsides?
Use a mower with anti-scalp wheels or a floating deck. Adjust the deck height to avoid digging into high spots. Some mowers have deck leveling adjustments to compensate for terrain irregularities. Slow down on bumps to minimize scalping.
Are diesel zero turn mowers better for hills?
Diesel engines typically offer more torque and better fuel efficiency, making them suitable for hills. They also tend to have longer engine life. However, they are heavier, noisier, and more expensive. For most homeowners, a high-torque gas engine is sufficient.
Our Verdict
After comparing specifications, safety standards, and owner feedback, the Hustler Super Z is our top pick for hillsides due to its exceptional traction, stability, and safety features. For a premium alternative, the John Deere Z950R offers diesel power and comfort for large properties. Choose based on your slope severity and budget.
