PickGuideMowrator S1 4WD 119% Slope Review: Is Their Best-Seller Worth It?
Mowrator's best-seller is the S1 4WD, a remote-controlled, tracked/tired all-terrain mower built for slopes and rough ground that push mowers and riding mowers can't safely handle. At $4,399 it's a serious purchase, so we went through the real spec sheet, the warranty terms, and a large, detailed review base — including reviewers' own reported quirks and limitations — before deciding if it holds up.
The S1 4WD uses four independent brushless motors for up to 1000W of drive power, rated for a 119% grade (50°) slope and a 3.94-inch obstacle clearance, with FOC torque control and electronic braking to help prevent rollback on hills. The 21-inch deck delivers up to 1985W of peak cutting power (Mowrator describes this as gas-mower-level output) with 6.0 ft-lbs of cutting torque, enough to cut grass up to 51 inches tall, and adjusts from 1.5 to 4.3 inches in height. It runs on a 56V LiFePO4 battery rated for 1,500+ charge cycles, giving 2.25 hours of continuous runtime and covering up to 1.125 acres per charge at a 3.4 mph top speed (0.5 acres/hour cutting efficiency). Beyond mowing, it mulches, bags, discharges, and — with the included mulching blade swap — becomes a leaf vacuum rated at 931 CFM suction into a 70-liter collection bag. The body is aircraft-grade aluminum alloy with a DC06 deep-draw steel deck, and it won an iF Design Award in 2025. On-site, it holds 4.88/5 from 283 reviews (89% five-star, 11% four-star, 1% three-star, 0% one/two-star). Independently, Mowrator's Trustpilot page shows 4.4/5 from 20 reviews (90% five-star), a smaller but consistent independent sample.
Pros
- Large, detailed on-site review base (283 reviews, 4.88/5) full of specific real-world use cases — multi-acre lots, steep hillsides, thatch removal, tall grass, wet mulching
- Real, specific performance numbers (1000W traction, 1985W cutting power, 119% slope rating) rather than vague marketing claims, and independently corroborated by multiple reviewers actually mowing steep hills
- Genuinely multi-purpose: the same machine mows, mulches, bags, discharges, and becomes a leaf vacuum with an included blade swap
- 2-Year Worry-Free Warranty with local repair support (California and Missouri) plus dealer service partners in multiple states
- 30-day price match guarantee and 30-day return policy on top of the standard warranty
Cons
- At least one detailed reviewer reported the system overheating under sustained heavy-duty cutting when using the optional high-lift blade, requiring cool-down breaks
- Remote control range is inconsistently reported: one reviewer said the safety cutoff limited them to about 50 feet before needing to disable sensors, while another reported going 300+ feet after disabling the distance safety feature — worth testing your specific yard's needs before relying on long-range use
- The electronics are not fully weatherproofed according to one reviewer using the optional FPV accessory, who had to stop mowing when it started raining
- At $4,399 for this flagship configuration, it's a major purchase, and at least one older reviewer specifically noted needing help with initial setup
- "DJI-grade" remote control and "former DJI experts" engineering claims are the brand's own marketing language, not independently verified by us
Who It's For
Good For
- Homeowners with steep slopes, rough terrain, or large lots (1+ acres) that a push or riding mower can't safely or efficiently handle
- Buyers who want one machine that mows, mulches, bags, and vacuums leaves rather than several separate tools
- Anyone who wants to check a large, detailed, real-world review base before a $4,000+ purchase
Skip If
- You do heavy-duty cutting with the optional high-lift blade regularly and aren't prepared for potential overheating and cool-down breaks
- You need guaranteed long-range remote operation beyond a modest distance without adjusting safety settings
- You want to operate it in the rain — the electronics aren't described as fully weatherproof by at least one reviewer's real-world experience
How It Compares: Mowrator S1 4WD 119% Slope vs DigMaster Remote Control Track Lawn Mower
| Spec | Mowrator S1 4WD 119% Slope | DigMaster Remote Control Track Lawn Mower |
|---|---|---|
| Price | $4,399.00 | ~$2,000 USD (converted) |
| Power source | 56V LiFePO4 battery (electric) | 9HP gas engine |
| Cutting width | 21 inches | 21.6-26.15 inches (variant-dependent) |
| Weight | 114.8 lbs | 302 lbs |
| On-site/marketplace rating | 4.88 / 5 (283 reviews) | 4.0 / 5 (6 reviews) |
The DigMaster is roughly half the price and uses a gas engine rather than a battery, but it's also nearly triple the weight and has a much thinner review record (6 reviews) to evaluate against. The S1 4WD's battery-electric drive means no fuel to buy or store and quieter operation, at a real premium in price. If budget is the priority and you're comfortable with gas power and a much smaller review sample, the DigMaster is cheaper; if a lighter, quieter, more extensively reviewed electric machine matters more, the S1 4WD justifies its higher price.

Frequently Asked Questions
Can this mower really climb a 50-degree slope safely?
Mowrator rates it for a 119% grade (50°), and multiple independent on-site reviewers specifically describe using it on steep hillsides their previous mower or riding tractor couldn't handle. We can't independently verify the exact maximum angle, but the real-world reviews are consistent with the claim.
Does it work as a leaf vacuum right out of the box?
You need to swap in the included mulching blade first — the leaf-vacuum function isn't simultaneous with the standard mowing blade. Once swapped, it's rated for 931 CFM suction into a 70-liter bag.
Verdict
The S1 4WD backs up its flagship price with real, specific engineering — four independent motors, a genuine 119% slope rating corroborated by real hillside-mowing reviews, and true multi-season versatility as a mower, mulcher, bagger, and leaf vacuum in one machine. The review base is large, detailed, and largely positive across both on-site (4.88/5, 283 reviews) and independent Trustpilot (4.4/5, 20 reviews) sources, though a few specific, credible owner reports — occasional overheating under the heaviest cutting loads, inconsistent remote range, and non-waterproof electronics — are worth knowing before you commit $4,399. For a yard that genuinely defeats conventional mowers, it's a well-engineered, well-reviewed solution as long as you go in aware of those real-world edge cases rather than expecting flawless performance in every condition.
