Alright, My brother was parading around on a 20Horse Craftsman that he swapped pulleys, dropped the deck, and got clocked going 42MPH down the Metro Airfield...

Being the older brother, It is my duty to one up him in everything he does, so I tried swappin' pulleys, removing the governor, dropping weight, ect. on my 14 horse murray, but it just can't compete. So I figure I'll show 'em.

I've got an ol' 80's Mazda B2000 Pickup, with a 4 banger and 5spd, that should fit nice and snug in the Murray, with a little coaxing and a heavier frame :evil:
I figure on using the Mazda rear axle, or maybe even a big dually axle? :thumbup:

I'll get some pics and keep y'all updated.
In the mean time, comments, concerns, suggestions, or fellow ********, post at will.

The Mazda 4 banger is carbureted, and has a distributor, no electronic gizmo's I can't figure out, so I just have to make a frame to support it.

The 5 speed is pretty small, so i think it'll fit alright, I may have to lengthen the mower a little, but not much. Plus, it's got a Hydraulic Clutch, so that's handy as well.

The mazda rear end is really high geared, like 3.07, so it'll go Entirely too fast for my little mower.. But I'm sure I can scrounge something up that'll work, more or less.

Front suspension, I'll probably end up making my own, so I'll see how that goes. Manual Rack and Pinion may be my best bet, or the gear box out of the Mazda?

I'm thinking I'll keep it stock height, about 8" of clearance on the bottom, maybe lower it a few inches, stretch the frame, so I'll have more leg room, and lower my seat.
Possibly give it a Rat Rod look, with the patina, and raked front clip?
I guess I have to get things mocked up before I get too carried away...

This guy put a sbc in a mower, keeping the original hydrostatic drive:

My buddy down the road from me put a Buick V-6 in his mower. He made the front cover of the magazine pertaining to hi-powered lawn mowers. I was more amazed that there was a magazine devoted to hi-powered lawn mowers! I guess people have to keep with everything new in lawnmower racing. I wonder if the tech articles start with " First remove the cutting blades---"

Motorcycle? Still too small, and won't have the "cool factor" haha
Go big or go home! I'd put a SBC or hell, even a BBC in it if I had an extra laying around, and the money to do so, but all I have is the little 2.0L so that'll have to suffice.
85hp, or whatever it has, should scoot a 1000 pound mower down the road, as fast or faster than I care to go.

My question is IF you did that---put a car engine/trans in a mower how would you run the blades? i know you probably don't want to do that, but i admit i would like to use a car drivetrain, yet still be able to cut grass as i have a very big lawn.

Yes, the sane thing would be to just get a sitdown mower at home depot, but i don't want to do that.


2) What would the mpg be, or better yet stated how long would tank of gas last with say a SBC vs. the typical lawmower engine.

How much faster would a car engine consume gas vs. a typical lawnmower engine keeping in mind the car engined mower will be able to mow a lawm much faster (i think?).

3) RE: the mover above pictured: If you ran a car rear axle (narrowed hopefully) with car tires, how would the affect the mow pattern---would it leave unsightly tracks in the grass keeping in mind there is probably not a whole lot of weight back there.

NOTE: You are probably aware that when you mow in rows back and forth, it looks good. i'm wondering if you ran car tires---say 155/70 r 14's to 195/75 r 14's/15's would this mess things up?

You might be able to manage it by running the blades off a PTO in the tranny, if it has one? But the deck is already off mine, and if it ever touches grass, it'll be leaving Ruts :evil:
but depending on how big the yard is, you can only mow so fast before you have to turn around and make another pass. Unless you made a wider deck that is.

Running a PTO would be easy....Many garden tractors have electric PTOs which mount on the front of the engine, where the balancer is on a v8

At swap meets I do run into rear ends that have been narrowed for a dragster..use one of those with an open third member so it turns easy..wide turf tires work well..PTO may be a bit of a challenge depending on the tranny used but then there are some granny geared truck trans with provision for PTO..Sure thing a fellow can build a tractor using available parts as that has been done in the past...50 years ago one of our neighbors built a homemade tractor using pieces from a wrecked logging truck and we got a lot of good use out of that thing..He had the brakes rigged so he could brake one wheel so that thing would turn on a dime..used it to grade the road and skidded logs with it as well as other things..wasn't much for mowing lawns as I recall though..

Probably the easiest way would to build a out rigger assembly on each side. After visiting a few yard sales and obtaining six or eight walk behind powered mowers you could attach them to the out riggers on each side staggering them a little to insure a overlap of the cutting line. . I'd suggest 14 to 18 inch racing slicks so not to leave tire tracks on your lawn. Discharge shoots would have to be fabricated to direct grass clipping away from the other mowers which probably means you would want to wear goggles. MPG would not be a problem because of the size of your cutting path. I would imagine one or two passes and you would be done with mowing for the day. As far as the tedious job of starting all of the individual mowers , purchase only electric start mowers. This might mean that you would have to resort to installing one of those extra large truck batteries but that could work to your advantage. Place it directly behind you on a rack assembly and the weight of the battery will help with traction or your slicks. Of course if you have a sloping lawn you might want to install wheelie bars so you don't tip backwards going up hill. Having up to 8 (or possibly 10!) electric start mowers I personally would obtain a WW1 leather flying helmet ( to add a little color to the experience) and together with my goggles in place would yell at the top of my lungs " Clear!!" everytime I started a mower. ----Yes I could see mowing could be fun.
