Official FX-RM4346ECO specifications
FUXTEC lists the FX-RM4346ECO as a walk-behind petrol mower with a 146 cc engine, 42 cm cutting width, 40 litre grass collector and central seven-position height adjustment. Its detailed specification gives 25–70 mm; a separate benefits bullet says 25–75 mm. The same page gives 22.8 kg net in the technical table and approximately 25 kg in the description. Its benefits text mentions side discharge, while the structured fields say rear ejection is available and side ejection is not. We report these inconsistencies rather than presenting one version as settled. FUXTEC says the mower has no self-propulsion and no mulching function.

FUXTEC publishes conflicting lawn-area figures
The same manufacturer page describes the machine as suitable for lawns up to 400 m², while its technical data table lists a recommended area of 1,000 m². That gap is material when comparing a petrol mower, so this page does not choose one figure or estimate a mowing time. Ask FUXTEC for the applicable recommendation and consult the manual for the exact regional version.
What to confirm before ordering
Check the FX-RM4346ECO model code, current manual, collector and discharge equipment, fuel and oil requirements, delivery area, warranty and spare-parts support. The evidence here is FUXTEC Spain’s page and the FX-RM family manual; it does not establish that an identically named unit in another country has the same engine, emissions approval, accessories or service coverage.
For a broader comparison of petrol mower formats, see the gas lawn mower guide.
The official FX-RM series manual covers the model family and should govern setup, fuel, oil, blade and safety procedures. For a wider 46 cm sibling, compare the FUXTEC FX-RM4646 guide, while checking its distinct specifications rather than transferring them to this mower.
Understand the engine and cutting figures
The 146 cc figure is engine displacement; it is not a direct measure of the area a mower can finish in one session. FUXTEC lists maximum power of 2.6 kW and nominal power of 2.2 kW separately. Keep those labels attached to the numbers when comparing offers, because peak and continuous ratings are not interchangeable. The official listing also gives a 0.8 litre fuel tank and 0.5 litre oil capacity. Check the current manual for the specified fuel, oil grade, filling procedure and service interval rather than treating capacity as a maintenance schedule.
A 42 cm cutting width can reduce the number of passes compared with a narrow deck, but the advantage depends on the lawn’s shape. Measure gates and paths before purchase; the mower must fit through its narrowest access point and leave room to turn. The 40 litre collector is a stated capacity, not a guarantee of how frequently it needs emptying. Grass length, moisture and cutting height affect how quickly it fills. If the lawn is overgrown, follow the manual’s advice about removing only a safe amount per pass instead of forcing the machine through long, wet grass.
FUXTEC lists seven central height positions. Its detailed specification gives a 25–70 mm range, while a benefits bullet says 25–75 mm; confirm the range with the manual or seller if the upper setting matters. The mower is listed as push-only and without a mulching function. A user therefore needs to provide the forward effort and manage clippings using the equipment and discharge arrangements supplied with the exact package.
Check lawn layout, slope and physical handling
FUXTEC gives 22.8 kg as net weight in its technical data but describes the mower as approximately 25 kg elsewhere on the same page. Neither figure is a loaded weight with fuel or cuttings, and the page does not provide a tested pushing-force figure. For a sloping plot, narrow borders or frequent tight turns, check the operating manual and consider whether a self-propelled model or a lighter mower is a better fit. Do not assume the engine rating resolves a handling issue.
Plan a route that avoids repeated sharp turns around trees and beds. Pick up stones, wire, toys and branches before mowing; keep people clear of the discharge area; and stop the engine before inspecting or clearing the blade. Review the safety instructions and required protective equipment for the exact model. If you cannot confirm how the mower should be used on the site’s slope, ask FUXTEC rather than extrapolating from a generic petrol-mower guide.
Area is only one part of fit. Walk the route from storage to lawn and note steps, gates, gravel paths and any turn that requires lifting or reversing. The listed net weight excludes fuel and clippings, so a full collector can increase the effort between passes. If the mower must be carried through a house or up steps, test that handling before choosing a petrol model.
FUXTEC does not establish a maximum slope in the cited product page. Do not infer one from the 146 cc engine or from another walk-behind mower. Check the manual for slope restrictions and stop if the ground is wet, loose or too steep to keep stable footing. A push-only machine needs the operator to control its speed and direction on the slope as well as supply the forward force.
Plan a realistic mowing workflow
The 42 cm deck and 40 litre collection bag describe the machine; they do not establish how long a particular lawn will take. The cutting path may be narrower than the deck once you allow for borders, trees and safe turning. Measure gates and narrow passages, then consider where the mower can be turned and stored. If the lawn has several separated sections, include the time required to move the mower between them; it does not travel between areas by itself.
Because the FX-RM4346ECO is listed as push-only, the operator supplies the forward force. This matters on sloping or uneven ground, where surface grip and fatigue affect whether a session feels manageable. A 22.8 kg net-weight figure is not the same as the weight with fuel, oil or a full grass collector. Do not choose a model solely from engine displacement if the day-to-day push effort, storage space or access path is the limiting factor.
FUXTEC lists seven cutting-height positions from 25 to 70 mm. Adjust height with grass condition and the regional care advice for the lawn type, and make a smaller first cut if the grass has grown long. A 40 litre collector can fill quickly when grass is wet or dense, adding stops and handling work. The manufacturer page does not list a mulching function, so do not rely on a generic claim that clippings can be finely returned to the lawn.
Before each use, follow the current manual for the oil level, fuel, controls, blade and safety equipment. The product page lists a 0.8 litre fuel tank and 0.5 litre oil capacity, but those volumes do not set the service interval or fuel mix. Use the exact engine instructions and never open or service a hot machine. Stop the engine and wait for the blade to stop before clearing grass from the deck or collector outlet.
Confirm fuel, service and regional support
The source is a Spanish-market FUXTEC page. That supports the published Spanish product information; it does not prove that a product with the same marketing name sold elsewhere has the same engine, emissions approval, accessories or warranty. Before ordering outside the supported market, confirm the exact rating plate, manual language, replacement blade, engine-service parts, delivery restrictions and the party that handles warranty claims.
Before the first start, read the manual for the correct fuel and oil, assembly, blade inspection, starting controls and safe stopping procedure. The listed 0.8 litre tank and 0.5 litre oil capacity are container capacities, not a runtime or service interval. Keep fuel away from ignition sources, let a hot engine cool before refuelling and store fuel only in an approved container. If the Spanish product information or seller instructions disagree with the manual supplied for the exact unit, ask FUXTEC to identify the correct revision before operating the mower.
Follow the manual’s maintenance schedule: check oil, inspect the blade and fasteners, clean the collector and keep the air intake clear. Do not use the same service interval as another engine just because its displacement is similar. Record the model code and serial number, then confirm blade and filter fitment through the manufacturer’s parts route.
When you contact the manufacturer, send the full code FX-RM4346ECO and ask it to resolve the two area figures in writing: 400 m² in the description and 1,000 m² in the technical table. Include the lawn’s shape and slope in the question. Until that discrepancy is clarified, avoid describing this mower as a confirmed choice for either maximum lawn size.
