hello

l have been having a bit of trouble with my old ride on mower as of late, its on its last legs and needs replacing really
however when l look around at the price of new its a non starter :confused2:
so since l always enjoy a project l thought l would have a go at building one from scratch
below is a pic of the sort of style and layout l want, except l want to be able to fit a rotary deck or flail mower on the front
and not cylinders as the area l have to cut is a bit rough

to keep costs to a reasonable level l will have to use components l have or can get get cheap rather that what might be best
as its always bl**dy raining here l think 4 wheel drive is a must as is a diesel engine

l have been into offroading suzuki's for a long while so the parts bin is full of suzuki stuff lol,
sidekick/tracker has a nice wide rear axle that is quite robust too so that will make a nice front axle on the mower
and a sj front axle will take the sidekick front diff to match the ratio's, the long side is easily cut down to the same length as the short side giving a nice narrow steering rear axle that has matching ratios

the other bonus with using suzuki axles is that the stud patten matches up with the wide wheels l already have

Sounds like a very interesting project. Keep us informed as to how it's going. I didn't do a lot of off roading, but did buy a new Suzuki Samurai in 1986 and kept it for over 3 years. It was quite a toy.

hi

cutting the long side down to the same as the short side meant l could just use another short side halfshaft but the axle isent quite
narrow enough but l might have to live with it

l wanted the rear wheels to run inside the fronts so as l could use the mower as a roller too, but when the wheels turn they use up so much space and l have to get a chassis through there between the tyres out to a tow hitch on the back

power plant is a fwd car engine and box turned sideways with the diff welded up or better still a LSD fitted, in this case its a peugeot 1900cc engine fitted into everything over and as cheap as chips, the one l am using for mock up is a manual but will get swopped for an auto before its finished

This whole forum is absolutely incredible!

People like u, AndyUK, are the reason why.

I liked your new ride as soon as I saw the first pick with the tires in it!

Absolutely amazing, what so many here can do.

Great work!!!

Interesting project. What ground speed are you anticipating with the automatic transmission?

well l will be happy with what ever l get after all its a mower, my present mower seems to cut happy at walking speed 3mph ?
but it is on its last legs and wheezes along like an asmatic snail so a little faster might be good,
the car the engine and box came out of had a top speed of around 80 mph on level ground clearly l have a second diff in the drive train now so that will get cut by a factor of 4, so that is 20 mph flat out but l dont want to run the engine flat out so lets assume 12mph at a steady engine speed then add back in some for the increase in tire size l have gone from a 21" dia to a 31" tire so thats a 50% increase ? which gets us back to 20 mph or more for travelling on the road, it would be easier to calculate accuratly if it was a manual gearbox with fixed ratio's but the auto is a bit wishy washy

l have to make a decision on the engine and box at some point as l have a choice to make here, the engine and box l have in the workshop is a 1.9 turbo diesel with intercooler and manual gearbox but l also have a complete working driving car with the same 1.9 engine but its a non turbo but with an auto box, now l like the idea of the auto box as its far easier to arrange the gear change than it is with a manual gearbox, however the extra power from the turbo would no doubt be usefull too as l want to drive a big hydraulic pump of the crank pully, the intercooler sat up on top of the engine wont see any natrual airflow so will be as much use as a chocolate fire guard but l was pondering fitting 2 electric fans above the intercooler that were activated by a switch on the accelerator pedal at around 2/3 rds or 3/4 pedal travel so when travelling on the road the intercooler might be doing something usefull ??,

l have these cutting decks l bought of ebay for around $150,

the centre one has 3 blades but is not quite wide enough so l might make a new deck that will carry 4 blades/motors that is the full width of the mower but would like to arrange it so it will swing sideways to stick out 2' or so so l can mow under the trees up to the hedge with out the branches knocking my false teeth out

those little samurai's are great little things, l still have a few kicking around the barn lol, they will run rings round my landrover due to their lightweight and nimblness but horses for courses l wouldent want one for a daily driver and as for towing an empty trailer is too much for it lol, did you get the lwb version overthere ? well l say lwb its the same as everyone elses swb

its always the wheels and tires that get peoples attention, if l dident have them already l probally wouldent have started building this, l like to have them on early as l find it motivates me to get on and do something to get it finished
