Ive got a 4 horse briggs off a push mower mounted in a murray mower that i use as a snow pusher and to tug trailers. I need to get as much power as i can outta this thing without blowing it up or emptying my wallet. any ideas?

thanks. i was trying to read that this mornin and forgot about it.

Yup no problem. You can also re-gear it for that low end power your gunna need. I also recommend tire chains and weights. But, now that i think about it, that 4hp was off a lawnmower-not exactly a powerhouse for a actual tractor. Id recommend a bigger engine. Search craigslist.com for a vertical shaft engine, they go very cheap.

well i plowed with it all last year it just was slow goin.lol i got quite a bit of weight and chains on it. problem was if it hit a tough spot it would stall the engine.

Yeah id go with a bit bigger engine, people even throw these vert. shafts away. They are all over for cheap. You can mod that 4hp, but there's only so much you can do on a budget and keep it reliable.Most mods done to these are for higher RPM and not just to chug along at a bit more than idle speed.

ive got a 8 horse to rebuild and put on there but thats on hold for now. i was just hoping to be able to get by this winter with what ive got.

Well i would just take the head off and clean up the ports with a dremel, grind off the eyebrows, set the idle a bit higher, maybe get a good header pipe, and you'd be set.

 

[johnboggs21]

sounds like a good deal. ill keep checking back here in case anyone else has any ideas or if you think of something else.
thanks

you could also gear it down more, sounds like it slows you down and you die? is that a direct drive or with a tranny?

 

[johnboggs21]

its got a peerless transaxle. it will only stall if i hit something solid under the snow. like frozen snow from last time i plowed and sometimes if theirs a lot of snow.

You cant stall a 8hp motor running full throttle in first gear.

i know that but the 8 horse needs some help and im a little hard up for cash at the moment.

Your not going to be running WOT in a tractor pushing snow...

I didn't think i could stall a V6 doing a neutral drop but i did...

I beat the **** out of a craftsman with a 8hp swap for several years, it was unstoppable, but when it got unsteerable i scrapped it out and put the motor on a different mower that came with a blown 12.5hp motor just like the craftsman.
