Seeing that this Greenfield has a 8.5 Hp motor John ,I had thought it looked a bigger motor ,I'd say now this
was originally a 8 Hp Briggs motor .

The front of the bonnet being lower shows it being the 8 Hp model and not the 10 / 11 HP model

There is a manual here, but you may need to copy and paste the following into address bar https://greenfield.com.au/wp-content/uploads/2023/11/Tractor-Complete.pdf#:~:text=MODEL%20DESCRIPTION%208%20VR%20or%208%20VE,recoil%20start.%20Page%202.%20GREENFIELD%20TRACTOR%20MOWER.

Ah, I see Hudson has a classic hardware limitation (lack of thumbs). My database suggests
upgrading his treats to see if it fixes the tool-delivery latency .

Hi Bumps,
That will do it no problems, I thought you had split the wheels apart. It is not too difficult to make up a jig so you can press them back together but this idea saves the messing around

Hi MM,

It sounds like it could be The 1E44F-5 is a common 52cc, Engine Specifications Displacement: 51.6cc to 52ccPower Output: Typically ranges between 1.4 kW and 1.8 kWOperating Speed: Max engine speeds of 6,500 to 8,500 RPM, with an idle of around 3,000 RPMFuel Ratio: Requires a 2-cycle oil to gasoline mixture, commonly at 25:1

I usually keep them as they use them in a ton of equipment and are a handy motor for a lot of projects.



Lawn & Garden Equipment

Heavy-Duty Brush Cutters / Whipper Snippers: This is the absolute "sweet spot" for this engine. It is the default motor for almost every unbranded, budget straight-shaft brush cutter on the market.

5-in-1 Multi-Tools: The exact same power head paired with quick-release split-shafts to switch between a line trimmer, pole chainsaw, hedge trimmer, and brush blade.

Mini Garden Tillers / Cultivators: Because the 51cc motor is lighter than the 61cc, it’s the most popular choice for those small, lightweight tillers used to churn up garden soil and flower beds.

Lawn Edgers: Dedicated wheeled or stick edgers used to cut clean lines along sidewalks.

2. Recreation & Gas Toys (The "G-Scooter" Engine)

Stand-Up Gas Scooters: If you see a generic Chinese gas scooter (often called a "Stand-Up Extreme" or "Mach 1"), it almost certainly has this 51cc/52cc engine bolted to a small chain-drive gearbox.

Gas Skateboards / Motoboards: Off-road skateboards with hand-held throttle cables and a 51cc engine mounted over the rear trucks.

Pocket Bikes & Mini Dirt Bikes: Small "pocket rockets" (like the generic MTA2 or X1/X2 styles) and 50cc-class kids' dirt bikes.

Drift Trikes: Custom or factory-built three-wheelers with slick PVC rear tires for drifting on asphalt.

3. Farm & Construction Tools

One-Man Earth Augers (Post Hole Diggers): While the 61cc is used for heavy, two-man augers, this 51cc engine is the go-to for lightweight, one-man post hole diggers.

1-Inch Water Transfer Pumps: Lightweight, portable pumps used by farmers and homeowners to move water out of flooded areas or trenches.

Gas-Powered Fence Post Drivers: Handheld pounding tools used to drive T-posts into the ground using a heavy internal piston slammed by this motor.

Portable Winches: Small, gas-powered capstan winches used by hunters to drag game or loggers to pull small trees.

4. Marine & Special Applications

Kayak & Dinghy Outboards: Extremely popular for budget, air-cooled 2.5 HP to 3 HP outboard motors used on small fishing boats and inflatables.

Gas-Powered Concrete Vibrators: Used on construction sites to settle wet concrete and remove air bubbles.

The Secret to this Motor

Whether the sticker on the plastic shroud says 51.2cc, 52cc, 517, or has a brand name like Demon, Texas, Viron, or Timbertech, if it has a 44mm cylinder bore, it is the exact same engine. Parts are universally interchangeable, dirt cheap, and available everywhere.
