Draper Expert Petrol Generator with Wheels, 4000W

The Draper Expert PG43W is a professional open-frame petrol generator delivering 4,000W of rated continuous output — a practical, well-balanced choice for construction sites, agricultural operations, outdoor events, and remote power applications where reliable sustained performance matters more than maximum peak wattage.

Powered by a 389cc four-stroke OHV engine producing 13HP and a maximum AC output of 4,400W, the PG43W provides sufficient capacity to run multiple power tools, site lighting, and ancillary equipment simultaneously across both 110V site standard and 230V domestic voltage outputs. The 25-litre fuel tank delivers an impressive 9 hours and 9 minutes of continuous runtime at 75% load — exceeding a full working day on a single fill and placing the PG43W among the longest-running generators in its output class.

At 79.7kg net weight — the lightest in the Draper Expert wheeled generator range — and fitted with two large robust rubber wheels, it offers the best balance of power, runtime, and manoeuvrability across the PG series. Fully compatible with E5 and E10 petrol, it runs on standard UK forecourt fuel grades without modification or additives.

Key Features & Benefits:

389cc Four-Stroke OHV Engine
The forced air-cooled four-cycle overhead valve engine delivers 13HP in a configuration built for sustained load operation. The OHV design runs at lower operating temperatures and with greater thermal efficiency than side-valve engines — reducing oil consumption, extending service intervals, and contributing to a longer overall service life. For a generator expected to run for extended periods on site, these characteristics have a direct impact on running costs and reliability.

4,000W Rated Output — 4,400W Maximum
The PG43W delivers 4,000W of rated continuous AC output (5.0kVA), with a maximum peak capacity of 4,400W (5.5kVA) to handle the startup inrush demands of motor-driven equipment. This output level is sufficient to simultaneously power a range of common site tools — angle grinders, circular saws, site lighting, battery chargers, and small compressors — making it a practical choice for smaller construction sites, sole traders, and agricultural users who don't require the full capacity of a 5,000W or 6,000W machine.

Dual Voltage Output — 110V and 230V
The PG43W provides four separate socket outputs covering both voltage standards:

• 1 x 110V 16A — standard site tool socket for CTE-compliant equipment
• 1 x 110V 32A — high-load 110V distribution and larger site equipment
• 1 x 230V 16A — domestic voltage for mains-standard equipment and appliances
• 1 x 12V DC — vehicle battery charging and DC accessory power

This socket configuration allows the PG43W to serve mixed-voltage requirements simultaneously — supporting both site-standard 110V tools and 230V equipment from a single generator without the need for voltage adaptors or additional distribution equipment.

12V DC Output
The 12V DC output enables direct vehicle battery charging and powering of 12V accessories alongside the AC outputs — a useful addition for agricultural, groundskeeping, and remote site applications where DC power requirements arise alongside standard tool use.

Recoil and Electric Start
Both electric key start and recoil pull-start are included as standard, with two keys supplied for the electric start system. The recoil backup ensures the generator can always be started manually if the starter battery is flat — a practical safety net for remote locations and early-morning site starts where servicing support isn't immediately available.

25-Litre Fuel Tank — 9.15 Hours Runtime
The 25-litre tank provides up to 9 hours and 9 minutes of continuous operation at 75% load — a longer runtime than the higher-output PG58W achieves at equivalent load, reflecting the PG43W's more efficient fuel consumption at its rated power level. For contractors, event organisers, and agricultural users who need all-day power without refuelling interruptions, this runtime is a genuine operational advantage.

Lightweight in Class — 79.7kg
At 79.7kg net weight, the PG43W is the lightest generator in the Draper Expert wheeled range — notably lighter than the PG58W (82.4kg) and PG68W (84kg). While all three require wheels for practical manoeuvring, the reduced weight makes a meaningful difference when loading onto a vehicle or positioning across uneven terrain.

Steel Tubular Frame with Anti-Vibration Mounts
The heavy-duty open steel tubular frame provides robust impact protection for all generator components and a stable operating platform during sustained use. The oil and fuel resistant anti-vibration mounts isolate engine vibration from the frame — reducing mechanical stress on internal components and limiting vibration transmission to adjacent surfaces during operation.

Two Large Rubber Wheels
Two large robust rubber wheels allow single-operator repositioning across site terrain, rough ground, and uneven surfaces — following the work as it progresses without requiring a second person or mechanical assistance.

E5 and E10 Fuel Compatible
Full compatibility with both E5 and E10 petrol removes a common concern with older petrol-powered equipment as E10 becomes the standard grade across UK forecourts — no additives, no carburetor adjustment, and no compatibility risk.

Supplied with Basic Toolkit
Two electric start keys, a spark plug spanner, and a 12V charging lead are supplied — covering initial setup and routine maintenance requirements without additional purchases.

Where the PG43W Fits in the Draper Expert Generator Range:

The PG43W is the right choice for users who need reliable all-day site power for a moderate number of tools and don't require the full capacity of the larger models. Its lower output also means a lower price point — making it the most cost-effective entry into the Draper Expert wheeled generator range for sole traders, small contractors, and agricultural users.

Typical Applications:

The Draper PG43W is well suited to:

• Small to medium construction sites — powering 110V and 230V tools and site lighting
• Agricultural and groundskeeping operations — remote field power for machinery and irrigation
• Outdoor events — catering equipment, PA systems, and temporary lighting
• Emergency backup power — sustained mains-equivalent output during outages
• Sole trader site work — providing all-day power for a single trade without over-specifying

Specification Summary:

Noise and Site Compliance:

The PG43W operates at 97dB(A) — consistent with open-frame generators at this power level. For sites with noise management requirements or proximity to residential properties, position the generator at the maximum practical distance from sensitive areas and refer to current HSE guidance on noise at work. The anti-vibration mounts reduce structure-borne noise transmission where the generator is operated on hard standing.

Warranty:

The Draper Expert PG43W is covered by a 24-month manufacturer's warranty as standard. Register your product with Draper to extend this to 36 months free of charge — an additional year of manufacturer-backed protection on a significant equipment purchase.

What is the runtime of the Draper PG43W generator?
The PG43W runs for up to 9 hours and 9 minutes continuously at 75% load on a full 25-litre tank — sufficient for a full working day on a single fill.

What sockets does the Draper PG43W have?
The PG43W is fitted with one 110V 16A socket, one 110V 32A socket, one 230V 16A socket, and one 12V DC output — covering both site-standard and domestic voltage requirements across four separate connections.

Does the Draper PG43W have electric start?
Yes — the PG43W features both electric key start and recoil pull-start as standard. Two keys are supplied for the electric start system.

What is the difference between the Draper PG43W, PG58W, and PG68W?
The PG43W delivers 4,000W rated output and is the lightest and most fuel-efficient of the three. The PG58W steps up to 5,000W with the same engine and runtime. The PG68W delivers 6,000W from a larger 420cc engine but with a slightly shorter 8-hour runtime. Choose the PG43W for moderate site power needs, the PG58W for heavier multi-tool use, and the PG68W for maximum simultaneous output.

Is the Draper PG43W compatible with E10 petrol?
Yes — the PG43W is fully compatible with both E5 and E10 petrol grades without modification or additives.

How heavy is the Draper PG43W generator?
The PG43W has a net weight of 79.7kg — the lightest in the Draper Expert wheeled generator range. Two large rubber wheels allow single-operator repositioning without lifting equipment.

What oil does the Draper PG43W use?
The PG43W uses SAE 10W-40 engine oil with a 1.1-litre capacity, available separately.
