best lawn tractor on hills image
EpicRacer
i installed a used B&S Craftsman I/C 17.5hp OHV engine in a scotts lawn tractor. it has been barely used in the last 2 years, according to the guy i bought it from.
it seem to have trouble on hills, hauling, and mowing. when i flip the throttle all the way up from idle, it takes a second or two to get up to max rpms. my old Intel engine revved much quicker than this.
when i engage the blades, the rpms drop by a few hundred rpms, and the blades also take a while to get up to speed. while mowing, the rpms drop further when i go up a small incline. they drop even more if i mow in 5th gear (i usually use 4th).
even when just driving around, the engine does not seem to have alot of power. i could pull wheelies and lay rubber down the driveway with my old engine, but this one just seems to be lacking the power.
why does it do this? i thought the carb may have been gummed up so i swapped it with my old one (exactly the same) but there is no difference. i also gapped the spark plug to .030"
the spark plug was at .025".
im just wondering why this engine does not put out as much power as my old one.

I'd be willing to bet that one of your valve seats have popped out from over heating. Being that it was used, you don't know for sure how well the last owner took care of it. If the carb was dirty or they never cleaned the old grass out of it periodically, etc... the engine will over heat from not getting proper air flow, allowing the block to expand. That's how the seats pop out!

What is the life expectancy of a John Deere mower?

We are looking at a 717a commerical zero turn and a residential zero turn. We mow about 4 acres, slight hills, some trees to go around. How long would we expect either of these mowers to last with regular maintenance and upkeep? Would we be better off going with a lawn or garden tractor?
Answer
If you are really going to mow 4 acres regularly, choose the commercial mower. They are made for mowing lots of land and for many more hours of usage. They cost more but last a very very long time with regularly scheduled maintenance of engine and equipment. There are commercial zero turn machines that have attachments if you want that type of machine. "Walker Mowers" make residential mowers to commercial spec. Go check them out, there are about 5 or six different attachments, even front loaders! Check out your warranty time periods, also. That is very important, especially with 4 acres!!!
