Finally got round to changing oils in advance of working event season. Never seen oil like it! Thick as thick custard and about the same colour. Methinks service long overdue! Even after flushing new oil now looks on the emulsiony side so guess I’ll change again at the end of the year. The rotor drive oil was the worst, almost too thick to run out. Anyway also sorted out clutch adjustment. After having found shards of metal on the gearbox drain plug I just had to do that! Now selects gears perfectly. Amongst other stuff also adjusted slow running with the excellent results below. The sharp eyed among you may notice I have painted the paint pot which is serving as a temporary cover to the linkages pending eventually sourcing or having made a proper cover.

Hi Dan
I used to have a Hatz Diesel Gem. Never did any major work to it, but there’s a manual here you may find useful if you haven’t already got it. Good luck!

Charlie, thanks for the response. The wheel drive flange has what look like 8 approx 1/4″ splines in it that match to the same on the “shaft”. I see a much smaller dia piece inside of that too, but since the wheels turn independent of each other when in neutral, I thought perhaps they are driven individually as well. This brings me to my next question……what is the fastener type on these machines? Metric? Wentworth? or another? The wheel studs seem to measure just under 13mm and I believe 2.00 pitch. I need to determine this to get longer studs to use with a T-bar puller.
Cheers!
Dan

Hopefully link sent with manuals, if I’ve remembered how to do it!.

Hello, my first post here and also looking for the manuals for the f80 as I need to make some adjustments and the manuals would be very helpful if possible. My email is Brickley.vincent@gmail.com

I am going on Holiday for a couple of weeks. When I return I will order the chain and see about making a tool box.
My unit hasn’t got the cover over the clutch fitted. If I am making a tool box I will have to make the cover as well. Can any kind person send me a picture and sizes?
I have access to sheet metal tools.
By the way. She started again today, first try!! So I think I have solved my starting problems.

Hi, yes all of the cylinders stop at the same time, speed up at the same time. I think it may be the mower engagement or clutch arrangement but no idea if this is hard to change or where I would go to get spares.

As you sit on the mower on the right the drive pulley that operates the cutters engages smoothly but keeps speeding up and slowing down and stopping even on a perfectly cut pitch which led me to think it may be the mower drive / engage clutch that is at fault.

Thanks fore the top tip though, much appreciated. First job I have done is to fit a little inkeeping tool box on the back as I completly understand what you say about adjustment!

Well, I seem to have cracked the starting problem.
When starting from cold. 1/2 choke, flood carb, remove HT lead. Open throttle about1/4.
Turn over Twice. Replace HT lead. And give a hard, fast pull on the upstroke.
Hot starting. 1/4 throttle. Pull over.
I think that using full choke was flooding the cylinder.
On another topic. Can anyone tell me the pitch of the tool bar lift chain.
It had 1/2″ fitted. But this is wrong.
Thanks.

Sorry Charlie. Should have made clear I only got plough recently! Andy, very proud is right, champing at the bit to use it!
I’ll tentatively suggest I’ll bring 56 plough and 5 (if 5 not playing up!)

Hi, I get my Zundfix fuses for my Holder B10 mail order from Germany, they don’t seem to have a problem sending explosives across to UK!

Hi charlie i did download instruction book .
Have had engine running don’t start till i put some oil around piston carb overflowing
Not been used for long time. Do wood shavings
Hang in tube? Will try out on allotnent soon.

[vhgmcbuddy]

Well, I’ll kick off. Assuming they’re running I can potentially bring any two of 5, 30, 35, 50, 56 tiller, 56 plough. I’ll try and bring anything others can’t.

[vhgmcbuddy]

Thank you . I have started with some simple pins and see how they go.. Should have then working soon on a rotavator ridger system, if they do not behave will add some wooden blocks. Got some apple which would be hard enough I think.

I expect with a bit of planning we could cover most of those, not sure about 10 unless you’re keeping something up your sleeve Charlie! Perhaps if we all said up front which we would like to or could bring we’d get more variety.

[vhgmcbuddy]

Can’t wait! I’ll be there at least one of the days. See if I can bring a couple of the noisy ones.
