changing the gearing of an 8 sp

Recommended Posts

I would like to mow a little faster than 2nd(H) and a little slower than 3rd(H). I figure that the easiest way is to get a slightly smaller transmission input pulley. Anyone tried this or have thoughts on the idea?

THERE IS NO DOUGHT IT COULD BE DONE.

THAT WILL EITHER SPEED UP ALL GEARS, OR SLOW DOWN ALL GEARS. :)

I FEEL YOU PAIN BECAUSE ALL MY TRACTORS ARE 8 SPEEDS.

BIGGER TIRES WOULD SPEED UP MOWING IN 2ND GEAR AND LOOK GOOD AS WELL. DON'T KNOW IF IT WOULD BE ENOUGH TO NOTICE.

FENDER CLEARANCE MIGHT BE A PROBLEM AS WELL.

HAVE TO READJUST DECK HEIGHT THOUGH....

I HAVE A 1998 314-8 THAT REALLY MOVES IN 2ND & REVERSE.

MY 1985 416-8 SEEMS SLOWER.

I have a 312-8 and I swapped an engine pulley from a hydro (about 5 1/4") instead of the original 4" pulley and it speeds it up in all gears, I like it.

That's the easy part, finding the perfect belt length that would disengage when the clutch pedal was depressed with a bit tougher, but I found one and it does work fine.

I put 26" tall lugs on my B60. They just clear the fender but not more than 6psi.

I think they look great. But when pulling in 1st high i run out of power fast, in 2nd low range I can stand it up on to wheels, so taller is faster at a Price to Power.

I know some one than change pullys and that worked out well.

trail and error, good luck. Changing pully and belts is mostly the lowest cost way to gain more speed.

I hope this helps.

On my 414-8 I replace the trans pulley with a 4 1/2" one, and that gave me a higher speed in all gears. The low, low gear is still very low.

I now mow in 2H ans sometimes on long straight passes, in 3H

FYI, the shorter belt I used with the 4 1/2" pulley, was a 79" Gates 6979 Powerated Belt.

Good question. I have the same problem. My Raider 12 is too fast to mow in 2nd and my Raider 10 is too slow in 2nd? My 314-8 is perfect for mowing in 2nd gear but I have been tilling with it all summer in 1st low :) Kevin
