Slope Mowing Guide
A one-page practical guide on what works at each slope category — 15°, 25°, 35° and beyond. What equipment fits, what doesn't, the safety rules that don't bend, and what not to attempt. For rolling and steep Northern Rivers blocks.
What's inside
- How to measure your slope without a survey (phone clinometer or rise/run rule)
- Six slope categories from gentle to severe — what each feels like, what fits
- The safety rules that don't bend (and why most rollovers happen in reverse)
- What autonomous mowing buys you on slope — and where it stops being practical
- What not to attempt — the most common steep-block injuries

Steep blocks aren't a maybe
Most acreage in the Northern Rivers has slope. Steep blocks are where mowing goes wrong: rollover risk on ride-ons, contractors refusing to quote, autonomous units stuck or stranded, dangerous DIY attempts. Picking the right approach for your slope category isn't optional.
This guide explains what each category means in practice, what equipment fits, and where the right answer is "let it be" and choose groundcover that doesn't need mowing.
Wet slope = no slope. Wait for dry conditions; a 20° wet slope behaves like a 30° dry one.
Who it's for
Acreage owners with rolling or steep terrain anywhere across the Byron, Ballina and Lismore hinterland. Useful whether you currently DIY, contract it out, or are weighing autonomous slope-rated options.
Who wrote it
AutoAcre is the Northern Rivers' independent multi-brand dealer for commercial-grade autonomous mowing equipment. The guide pulls from local hinterland experience — the kind of slopes a brochure spec doesn't tell you about.
