1. Hustler Super Z: Best Overall for Hills
In our evaluation, the Hustler Super Z stands out as a top performer for hills thanks to its heavy-duty fabricated deck and high-torque engine. Owner feedback consistently praises its ability to climb slopes without bogging down, and the hydraulic drive system offers smooth speed control. The ROPS and operator presence system add crucial safety for uneven terrain. However, its commercial-grade price point is a real limitation for homeowners who mow only a few acres.
If you need a zero turn mower for steep, large properties and have the budget for a machine that will last for years, the Super Z is an excellent choice. Those with smaller flat lawns may find it overkill and should consider lighter, more affordable models.
- Heavy-duty fabricated deck with reinforced spindle housings for durability on rough terrain
- High-torque engine and hydraulic drive system provide consistent power on slopes up to 20 degrees
- Operator presence system and rollover protection structure (ROPS) enhance safety on hills
Pros: Excellent traction and stability on steep inclines; Commercial-grade build quality with long service life
Cons: Premium pricing may not suit budget-conscious buyers
2. John Deere Z950M: Best Traction
Our research shows the John Deere Z950M with its optional 4WD system is one of the best for extreme slopes. Owner feedback highlights its ability to climb hills that leave other mowers spinning, and the diesel engine provides consistent power. The deck design helps prevent scalping on uneven terrain. However, the added weight of the 4WD system can leave ruts on delicate lawns, and the diesel engine requires more maintenance than gas.
If you regularly mow steep, muddy hills and need maximum traction, the Z950M is a strong pick. Skip it if your terrain is mostly flat or if you prefer a lighter machine to avoid lawn damage.
- Optional 4-wheel drive provides exceptional traction on steep, slippery slopes
- Yanmar diesel engine delivers high torque at low RPM for efficient hill climbing
- Edge Xtreme deck with deep-dish blades improves grass lift on inclines
Pros: 4WD option is unmatched for traction on steep hills; Diesel engine offers long life and fuel efficiency
Cons: Heavier weight can cause turf damage on soft ground
3. Scag Turf Tiger II: Best for Rough Terrain
In our comparison, the Scag Turf Tiger II excels on rough, hilly terrain thanks to its robust deck and suspension system. Owner reviews note that it maintains a clean cut even when bouncing over ruts, and the engine never struggles on grades up to 18 degrees. The twin hydrostatic pumps provide smooth, responsive control. However, its turning radius is wider than some zero turns, making it less maneuverable in tight spaces.
This mower is ideal for properties with uneven, bumpy hills where cut quality is paramount. If you need tight maneuverability around obstacles, consider a model with a smaller turning radius.
- Velocity Plus deck with adjustable baffles optimizes cutting on uneven ground
- Heavy-duty twin hydrostatic pumps and wheel motors for reliable hill climbing
- Suspension seat and anti-vibration system reduce operator fatigue on rough slopes
Pros: Exceptional cut quality on bumpy terrain; Commercial-grade components withstand heavy use
Cons: Large turning radius compared to some competitors
4. Cub Cadet Ultima ZT1 50: Best Value for Hills
Our evaluation of the Cub Cadet Ultima ZT1 50 shows it offers solid hill performance at a more accessible price point. Owner feedback indicates it handles moderate inclines well, and the fabricated deck is a step up from stamped decks in durability. The hydrostatic transmission gives good control for side-hill mowing. However, on very steep or thick grass, the 24 HP engine can bog down, and the mower lacks the heavy-duty components of commercial models.
This is a great choice for homeowners with gently sloping lawns who want a capable zero turn without breaking the bank. Skip it if you have steep, demanding terrain or need commercial-grade durability.
- Fabricated deck with reinforced leading edge resists damage on slopes
- Dual hydrostatic transmission provides independent wheel control for hill stability
- Comfortable high-back seat with armrests for long mowing sessions
Pros: Affordable price for a hill-capable zero turn; Good cut quality on moderate slopes
Cons: Engine power may struggle on steep, thick grass
5. Bad Boy Maverick 60: Best for Steep Slopes
Based on owner feedback and spec sheets, the Bad Boy Maverick 60 performs well on steep slopes, with a powerful engine and suspension seat that improve comfort. The deck leveling system helps avoid scalping on uneven hills. However, we identified a consistent complaint about the drive belt slipping under extreme load on very steep terrain, which can be a safety concern. The build quality is adequate for residential use but not as robust as commercial models.
This mower is suitable for homeowners with steep but not extreme slopes who want a feature-rich machine. If you frequently mow very steep hills, consider a model with a stronger belt system or shaft drive.
- High-back seat with suspension and foldable ROPS for operator safety on hills
- Dual hydrostatic pumps with cooling fans prevent overheating on long inclines
- Deck leveling system allows quick adjustment for slope mowing
Pros: Good power-to-weight ratio for climbing; ROPS and seat belt included for safety
Cons: Some owners report belt slipping on steep grades
6. Ariens Zenith 60: Best for Comfort on Hills
Our research into the Ariens Zenith 60 reveals it prioritizes operator comfort with a premium suspension seat and ergonomic layout. Owner feedback appreciates the smooth ride on uneven hills, and the engine provides adequate power for most residential slopes. However, its lighter weight and narrower wheelbase can feel tippy on steep side hills, and some users report difficulty maintaining traction on wet grass. The deck is durable but not as thick as commercial counterparts.
The Zenith is a good pick for those who value comfort and have moderate, gentle slopes. Skip it if your property has steep side hills or you need maximum stability.
- Suspension seat with adjustable lumbar support reduces fatigue on slopes
- Large turf tires provide decent traction on moderate hills
- Easy-to-reach controls and tilt steering wheel enhance operator comfort
Pros: Very comfortable ride on bumpy terrain; Smooth hydrostatic transmission
Cons: Not as stable on steep side hills as heavier models
7. Gravely ZT HD 60: Best for Maneuverability
In our evaluation, the Gravely ZT HD 60 offers excellent maneuverability, making it easy to navigate around obstacles on hilly properties. Owner feedback highlights its nimble handling and consistent cut on moderate slopes. However, the 24 HP engine struggles on steep inclines with heavy grass, and the lighter frame can feel unstable on side hills. The deck is durable for residential use but may not withstand commercial demands.
This mower is ideal for properties with many obstacles and gentle slopes where tight turns are needed. If you have steep hills or thick grass, look for a more powerful model.
- Compact design with tight turning radius for navigating obstacles on hills
- Dual lever steering with smooth hydrostatic control
- Deck wash port for easy cleaning after mowing damp slopes
Pros: Highly maneuverable around trees and flower beds; Good cut quality on flat and gentle slopes
Cons: Underpowered for steep, thick grass
Frequently Asked Questions
What is the best zero turn mower for steep hills?

How steep of a hill can a zero turn mower handle?
Most zero turn mowers are rated for slopes up to 15-20 degrees, depending on the model and conditions. Commercial models like the Hustler Super Z can handle up to 20 degrees, while residential models typically manage 10-15 degrees. Always check the manufacturer’s slope rating and use caution on wet grass.
Is a zero turn mower safe to use on hills?
Zero turn mowers can be safe on hills if used properly and equipped with safety features like ROPS, seat belts, and operator presence systems. We recommend mowing up and down slopes rather than across them to reduce the risk of tipping. Avoid steep slopes beyond the mower’s rated capability.
What features should I look for in a zero turn mower for hills?
Key features include a high-torque engine, heavy-duty fabricated deck, good traction (large turf tires or 4WD), a low center of gravity, ROPS, and a comfortable seat with suspension. Also consider a deck leveling system to prevent scalping on uneven terrain.
Can a residential zero turn mower handle hills?
Yes, many residential zero turn mowers can handle moderate hills, but they may struggle on steep or wet slopes. Models like the Cub Cadet Ultima ZT1 are designed for gentle hills and offer good value. For steep terrain, a commercial-grade mower is recommended for safety and performance.
