Is the gearing appropriate? I've no idea about the setup so apologies if it's already been well considered.
Another thought, you could power whatever you fit as a mower directly with a separate engine. Oil's ok and flexible with installation but it's hungry. You could make something like one of those tow behind ATV flail toppers.
Also, the vast majority of out front mowers are on pivot steers or rear wheel steer, I'm guessing this isn't essential but maybe there's a manoeuvrability advantage that way round.
I quite like the buggy as far as you have got it!
i think the radiator and fans are going to live where the passenger door would be if it was having doors, i dont fancy it at the front as the grass cutting might clog it up fairly quickly and at the rear i want to have some sort of carry box for the chains saw, hedge trimmer, axe, digging tools etc
right onto the prop shafts and fuel tank next, would like to get this running and driving before i start the cutting deck
Hi
well theres an awful lot of guess work going on here but yes i think im in the right ball park regards gearing, i think i used to mow at a fast walking pace so say 4mph ish, i stuck one of my suzukis in low box the other day and at a fast tick over (1000 rpm ish ) i was moving at around 2mph as far as i could tell, the suzuki transfer box has a low ratio of 2 to 1 i am using a landrover transfer box which is 3.3 to 1 low range so at least 50% lower and i have suzuki diffs which are 5.125 instead of the land rovers 3.54 which means ist low will be far to slow i should end up mowing in low 3 or 4 at 4 mph,, thats all guess work as i cant find a calculator at the moment but at the other end of the scale the top speed is probably north or 80 mph not sure i would want to do that lol
tow behinds are ok but ive never liked running the grass over and flattening just before the mower deck tries to cut it, i like out fronts as i think they give a better cut,
separate engine on the cutting deck was plan 47c but its complex with radiators fuel tanks etc and i want the cutting deck to lift somehow so i can sharpen the blades on a regular basis i dont need the extra weight of an engine to lift and the fuel spill out of the tank etc etc
and yes rear steer would be far more maneuverable but this is for one specific task and there are no sharp turns
hi yes electric fans lots of em lol, but good idea reverse them and blow the cuttings out by changing the polarity with a switch, i will adopt that ideaI presume you are using an electric fan. If so put a switch in the system to reverse the fan direction. It allows you to quickly and easily clear the rad of debris without leaving the seat and if already using an electric fan very cheap and easy to do.
A 2m deck is getting very big to power off hydraulics from your engine size. But with the radiator out the way it makes a PTO shaft off the crank a good option
thats quite nice but eats up my budget rather quickly lolI don't know if this would interest you it says open to offers so it may be worth a very cheeky offer

nice starting point but im to far down the road now and my flotation wheels wouldent fit the tractor back end, and leaving ruts is one thing im trying to avoid, i used to tow a roller round with a Isuzu trooper it did more damage than i was rectifying lolAll sounds fair enough!
I can't help wondering if, by the time you're looking at creating something to drive, something to lift and pumps/gearboxes to make all that work, if a complete unit could do the job, like a small tractor back end; eg;
Contains pto gearbox, hydraulic arms, oil pump to drive and lots of low range gears.
It's a bit of a way off where you're at now though.
thats quite nice but eats up my budget rather quickly lol
i remember watching that last year, something like that but different lol
and this is what i think i will engineer onto the front crank pully, standard tractor pto out put shaft, that way i can have a quick release pto shaft down to the deck which i can easily remove when i want to tip the deck up or remove the deck to fit another implement such as a flail for the brambles or powered broom for the yard
ive looked on ebay for a second hand one but they are dearer than new ones

i agree i need a away to disengage the drive to the deck but i havent got plan for that yet so any ideas are most welcomeYou will need to put a clutch in there some how. Obviously this is easy with hydraulics but a mechanical clutch is definitely needed if you are using a direct PTO shaft without a clutch that is a massive load to turn over on the starter motor. Also when traveling it's not the safest to be running around with blades spinning or stub shaft turning.
There are also a whole multitude of situations when you may be traveling and not want the blades running and turning the engine off to remove and replace the PTO shaft will soon become old

i wonder if i could feed the front crank pully straight into a gearbox so as i can select neutral on it
a suzuki sj transfer box maybe, that way i can have neutral plus two speeds hi and low and another pto out put that could go all the way to the rear to power the rear implement ???
some sort of heavy duty centrifugal clutch that dosent engage till the engine hits 1500 rpm would be goodIt would work very well but no clutch to engage it I'm just trying to think of anything that has an independent clutch unit.
I know bandit chippers do but doubt you would find a second hand unit cheap
