You can add a plough, ridger, potato digger, planter, mower, wheels or a pump to a walk-behind tractor, but whether a given implement works with your machine comes down to four things: the hitch (coupler), the wheel shaft, engine power and whether there is a PTO. Passive implements pulled on the hitch fit most machines once you have the right coupler. PTO-driven implements are matched to specific series and will not work without a power take-off.

How to match attachments to your machine: 5 checks
- Hitch and coupler. Passive implements attach to the rear hitch through a coupler, and couplers differ between series. Our catalogue lists separate couplers for the WEIMA WM1100 and WM1000, and for the WM900, WM900M-3 and WM500. If your hitch does not match the implement, you need the right coupler or an adapter. Not sure which one? Call us and we will check by model.
- Wheel shaft. Grünwelt GW-AX24 hubs fit a 24 mm hexagonal shaft, GW-AX32 hubs fit a 32 mm hexagonal shaft. Both have a 4 × 110 mm flange, the same pattern as Grünwelt GW-ER steel wheels. Measure your shaft before ordering. Hubs start at about 96 zł.
- Engine power. Two implements on a double hitch, a reversible plough or a digger in heavy soil load the tractor much more than a single ridger. For a light machine, choose lighter single implements.
- PTO. Rotary mowers, active tillers, powered diggers and pumps need drive from the power take-off. Example: the Weima WMKM1100-6 mower runs at 540 rpm and, according to its product page, works with the WM1000N-6 and WM1100-6. Without a PTO you are limited to passive implements.
- Track width. A longer hub widens the track, which makes the machine steadier on slopes and when ridging between rows. Match the track to your row spacing.

The table shows the general direction. We always confirm a specific tractor and implement pair by model, because hitch and shaft versions can differ even within one series.
Before you order: what to have ready
- The exact model name from the rating plate.
- A photo of the rear hitch.
- The wheel shaft size: 24 mm or 32 mm hexagon.
- Whether the machine has a PTO.
- The type of work and your row spacing.
Note that many walk-behind tractors in our range ship without engine and gear oil, which is stated in the product name. Fill both before the first job with an attachment.
Frequently asked questions
Do Grünwelt attachments fit WEIMA tractors?
Often yes, but the hitch and shaft decide. Hubs and wheels are chosen by hexagonal shaft size (24 or 32 mm) and the 4 × 110 mm flange. Hitched implements need a matching coupler. Give us the model and we will check.
Can I run a rotary mower on a machine without a PTO?
No. Rotary mowers, active tillers and pumps need drive from the PTO. Without it you can use passive implements: plough, ridger, share-type digger, harrow.
How do I measure the wheel shaft?
Remove a wheel and use a caliper to measure across two opposite flat faces of the hexagon. About 24 mm means GW-AX24 hubs, about 32 mm means GW-AX32.
Set or separate implements?
When buying a new tractor, a set with plough, ridger and digger is the easiest route because the parts are put together for that model. If you already own a machine, choose implements separately by hitch and shaft.
What if the implement does not fit after all?
You have 14 days to return it. It is still quicker and cheaper to check compatibility first, so ask us to verify by model.
