User Guide
Quick Start Steps
Pre-check
Check gasoline level (92# / 95# unleaded petrol only), engine oil level, battery connection, track tension, blade fastening condition.
Confirm the emergency stop knob is reset.
Remote pairing
Turn on the machine main power; turn on remote controller, wait for signal connection. Remote control effective distance: up to 500m (line of sight).
Engine start
Manual start version: Adjust throttle properly, pull the recoil starter rope firmly.
Optional electric start version: Turn start key to ignite.
Start mowing
Adjust cutting height electronically from 1–20cm via remote.
Control forward / reverse / turn, switch high/low speed as needed. Working speed: 0–4km/h.
Stop operation
First stop blade rotation, then move mower to flat safe ground.
Idle engine for 30 seconds, then shut down engine, cut off main power.
Max climbing capacity: 50 degrees. Mow along the contour line of slope (horizontal direction), avoid going straight up and down steep slopes.
Reduce speed when turning on slopes; do not make sharp sudden turns.
If slipping occurs, release the forward throttle immediately and back slowly to flat ground.
After every use: Clean grass residue, mud on tracks, blade deck and air filter surface.
Every 10 working hours: Clean air filter element; check blade tightness and track tension.
First oil change: after 15 working hours. Subsequent oil change: every 50 working hours.
Spark plug: inspect & clean every 30h, replace every 100h.
Battery: Check terminals regularly; avoid over-discharge.
Drain gasoline from fuel tank and carburetor if storing over 30 days.
Fully charge batteries before storage, charge once every 3 months.
Clean the whole machine, keep in dry, ventilated room, away from direct sunlight and frost.
Store remote separately, remove its battery.
A: Same core parameters, power, cutting width and climbing performance. ✅ 550A: Fully enclosed cover, better dust and grass splash protection, cleaner look, suitable for orchard & fine green maintenance. ✅ 550B: Open front bumper frame, easier engine inspection and fast cleaning, better for heavy weed & brush cutting.
A: Max climbing angle is 50°. We suggest mowing horizontally along slope contour instead of vertical up-and-down for safer operation.
A: Yes, hybrid fuel-electric design. The Loncin 9.5HP gasoline engine drives cutting, meanwhile the built-in 2200W generator charges the 24V battery pack automatically while running. No stop for external charging during continuous work.
A: Use unleaded gasoline 92# or 95#. Do NOT use mixed oil, diesel or poor-quality fuel.
A: 500 meters under clear line-of-sight environment. Trees, hills, metal barriers will shorten remote signal distance. Always keep the machine within your sight.
A: Light drizzle is acceptable, but heavy rain, ponding and muddy ground are NOT recommended. Water may damage generator, battery and gearbox.
A: Mostly caused by bent, loose or damaged blades after hitting stones. Stop machine immediately, check and replace blades. Also check if grass clippings stuck under deck.
A: Up to 2200 ㎡ per hour under normal grass condition. It varies with grass thickness, slope angle and weed density.
A: We supply full spare parts: blades, tracks, batteries, air filter, spark plug, gearbox, remote controller. Warranty covers main engine for 12 months; wearing parts (blade, track, filter, belt) are not covered by warranty.
