That’s great thanks Charlie – i need to have a read through with these at the machine as to be honest some of it is a bit double-dutch….

My neighbour has an MG5 with pto to drive a saw bench , he has fitted a new electric start diesel engine as he was struggling with crank handles due to arthritis he is well pleased with it. Spares both new and used are readily available, Neil Jarrett is very helpful.

Thanks for the warning .

Sorry to hear your tale of woe! I know the 2-stroke is the better machine but I can’t help myself!
I’m glad you said about the high speed adventures, I was sure I remembered you could change the gears to allow high speed trailering. Sometimes the old memory doesn’t let me down!
Keep us posted if you have better luck!

My Uncle had an M1 identical to this one. His was fitted with Aspera at new, which was an early casualty, he then replaced it with a Briggs 3.5Hp.

A word of warning. The correct spec Briggs for such an application has a “heavy flywheel” . If a rotary mower spec engine is used it will have a light flywheel and in the absence of the flywheel effect of a blade will tend to “snarch your wrist off” when starting !

Peter,
Bloody awful,So bad I went and bought another petrol one. Diesel one Broke the heart of a Marine Engineer trying to get it started, I have been told it is drawing air and need to replace existing copper Gaskets all round or get originals ones annealed to restore seals.

Seem to spend all my time looking for Hirth D24 Engine parts suppliers.I thought of fitting manual wind up starter to it as at 70 my spirit is willing but the flesh is weak? but they cost a fortune.So I’m looking at fitting a Home made electric / Manual start for the Hand start (Electric drill & Long reach Socket with spur on end to catch starter on machine.

The petrol one is going but in poor condition.I also used 700 Rotavator fitted with Pick Tines in my youth doing new house gardens, It had a Bull dozer Blade and Wheel Conversion unit along with a road trailer which I travelled (Approx 12 – 15 MPH) from building site to site in west of Scotland, but that is another story. Not getting any work done on either machine just now due to weather conditions. Also have a small 3 wheeled power barrow undergoing restoration.

I know of a Howard Bantam fitted with Lawn mower complete with Rotavator as on web site front page, it appears in good condition and used to be shown a local Shows in East of Scotland. Ideal for some TLC and then showing & demonstrating as working unit. If anybody is interested I will put them in touch with Seller.

best regards,Ian.

Excellent! How do you find the Hirth in its comparative old age! I have very fond memories of the one I used.

Thanks Charlie, I think I’ve overloaded my brain with this.
Going to have a break from the engine and paint the chassis instead not much head work in that.
Next big job for me is to get the flywheel off. I am looking for a puller or a knocker as I have read this is the way to go.
Cheers
John.
P.S It is the LAV 35.

Sorry for the delay rain stopped so have been preparing the veg plot for the spring planting I have had a problem with the clutch nut slipping after stripping the engine off so I could paint the new Engine mounting plate, probably a mistake with hindsight but we all make those. The rotabox is partially reassembled but an on-gong project as I still do not have the tynes needed but that can wait until the tractor unit is running correctly.

I did manage 3 furrows with the plough fitted off a Honda unit before clutch problems stopped play. I was able to get the soil brown side up with a Ferguson T20 – David Brown 2 furrow plough combination in the end. Not pretty but with the frost forecast this important task is completed.

I finally got some pictures of the tractor hooked up to the plough and riding seat / trailer combination. Purists will note that the Howard Orange is changed to house colours of Grey and Green. Perhaps at a later time a new paint job might be called for, at this time I am happy to think that the metal is protected from the elements stopping the rust.

Thought an update would be useful to record

Clutch nut is 9/16 BSF thread having damaged the threads I am in process of repairing with Helicoils.

I found that with the dog clutch removed a 17mm rounded but socket can be used to lock the PTO shaft.

Further dabbling with the SV54 has left me a little puzzled over the breather. Normal breather operation allows high pressure to escape from the crankcase and close when crankcase pressure is lower than the external air pressure (correct me if I’m wrong). On my Douglas, it is open to breathe in and out, which makes me think something is missing. Attached is a photo of the breather stripped down. I reckon that there should be something between the items arrowed. Anyone else had one of these apart before?

Thanks for the attachment Charlie is the LAV 30 35 40 the same as mine a LAV 32 72 368 ?
My next step was to remove the flywheel but its very hard to get off and I don’t want to break it any tips / I did think heat but not sure.
Clive did your uncles blow up or something ? I do have a Briggs spare but would like to try and keep it original.

I thought Aspera m/c’s were Italian
Put a search on Google for the manual
