I leave it to specialists to calculate the result of this conversion, but I very much doubt that the power obtained is sufficient to power a somewhat greedy electric motor. It would be better to mount a generator on your mower to get a mobile power source.

Yes provided you do not exceed the amperage of the alternator ... The battery of a riding mower with a low capacity similar to that of a motorcycle (15 Ah big max) ... it can make a small buffer to preserve the alternator but that's it, otherwise you risk to burn your alternator or rectifier ...

I think that the power (necessarily reduced on a riding mower) of the alternator must be between 200 and 400W max (or in amps: 17A to 33A) ...

You will also have to take into account the efficiency of the converter (85%) ...

In the end I think it is illusory to hope to exceed 500W, to check with the real power of your alternator.

Ah but that's why at home it does not happen instantly alone!

I should have chosen stihl ...

Damn ... Well, too bad ...

What's stupid about lawnmowers is that there is no PTO to just couple the generator (not a group that includes engine + generator).

I do not know if the "mower" part is still used, otherwise a "medium" handyman can consider adapting a pulley on the central shaft - the one on which the blade is normally fixed - and with some reduction calculations and a stabilized engine speed - this is usually adjusted - directly produce 220 V alternating current by attaching a generator to the side, vertically, at the appropriate power (and making sure that it turns at 3 rpm) [ see the side of very small groups whose engine is out of order].

Hello everyone, and sorry A.D. 44 to troll your starting topic on power tools with my question. : Oops:

Did67 wrote:... a "medium" tinkerer can consider adapting a pulley on the central shaft (of the self-supporting) - the one on which the blade is normally fixed - and with some reduction calculations and a stabilized engine speed - this is usually regulated - directly produce 220 V alternating current by fixing on the side, vertically, a generator at the appropriate power (and making sure that it turns at 3 rpm) [see the side of very small groups whose motor is out of order].

Indeed, I thought of this possibility of recovering energy from the central shaft of the self-bearing shown in photo. I always use the cutting deck with the 2 blades for mowing which is quickly removed thanks to 4 pins leaving easy access to the shaft of the central shaft; design a similar system that would allow for a "small" power take-off for ride-on mower seems very wise! : Idea: (I am also surprised that no one has yet to make this device ... maybe an idea to develop? :P )

That said, I just recovered a removable hedge trimmer blade from a Multi-function tool (Echo) (*) and I will try to adapt it to the self-range by a gimbal-type transmission system.

Otherwise, the idea of ​​coupling an alternating current generator 220 V (generator) is interesting and would open many possibilities of use of electric tools. Admittedly, we keep the source of origin in thermal but we widen possibilities of tools by the electric one: it is a way of making of hybridization in gardening! : Cheesy:

(*) To return to the starting topic (battery powered tools), are there power tools on battery Multifunction?

For the moment, I note that the multi-functionality of electric gardening tools is limited to the portability of the battery from one tool to another, but common motor part with a range of accessories does not seem to be marketed while the concept brings together rather positive opinions.

Yes, it exists, but I have not found in major brands. The reason seems simple: the electric motor is not expensive, so why pool it? In contrast to a powerful 2T engine (which does not pollute too much, laminated combustion, etc.) or worse, a motor 4T all positions.

An interchangeable engine block at Stihl is 400 600 euros.

Hi everybody,

there are garden tools that adapt to a drill or screwdriver as there is no video on youtube I am obliged to put the official link https://power-tools.fr/products/powerdr ... ur2WPFaFsk

sorry for spam
