1200 Mowing Speed

Seriously, it sounds like a 20% reduction might be just the ticket.

Buy a creeper!


Go ahead and buy a reduction drive. I'll be laughing it up when you guys are taking your trannies back apart to put the original gears in because now it's too slow, and you can't shift gears. At least with a creeper, you can shift back into direct drive.

I'm done. Have at boys!

A few things perplex me here.

It's not a separate reduction drive. All Cubs, IIUC, have a reduction gear before the transmission. I'm talking about simply lowering the ratio a little bit, by 20%.

Not a very neighborly attitude.

A 20% reduction lowers the speed in 1st from 2.3 mph to 1.8 mph. Doesn't seem that dramatic.

Why would this be any different than shifting gears with the original reduction ratio? I'm lost here.

With a different reduction gear you're always in direct drive, just rolling 20% slower.

Are we talking about the same thing?

I have owned a gear drive 102 with a creeper since the mid 70s. In case you do not know how a creeper works here goes. First with the creeper in low JMech is correct you absolutely should not shift gears. To do so you must stop, shift the creeper into neutral or high then shift the tranny then shift the creeper. What you cannot do is shift gears in the tranny like going from first to second while in low range. You do have six forward speeds but mowing in second high and then shifting into low range will not make it a little slower, it will make it a lot slower. Ground speed in 3rd low range is just a little slower than 1st gear high range. I very seldom ever used the creeper while mowing but it was a real asset when blowing snow although changing from a forward gear to reverse was more than just moving the tranny lever.

Anybody thought of a speed-up pulley for the deck? Same forward speed but higher blade speed = better cutting of thick grass.

I'd have to check the parts books but I thought there were 2 different pulleys that worked on the 44/50 in decks. 1 was faster

I replaced the pulley on my 44C deck with a larger pulley (went from 4" to 5" I think) so I could use it with my 1450. Made it a 44A deck I suppose? Belt size is different, too. I think the 44C used a 5/8 belt (for the 82 series tractor) while the earlier used 1/2 or 7/16 belts. Something like that. ccspecialties.org or ihccwh.com should have the pulley you need.

A larger pulley on the deck would make it slower, you must have went from 5" to 4"

I replaced the reduction input shaft in this 1200 because the yoke area was wore our. Removing and replacing the shaft was very easy, the gear is right there and looked to be easily removed as well, but I didnt remove the gear. HOWEVER, befor anybody has to go change thier depends, I will NOT be changing the shaft or gear in an attempt to reduce gear ratios. I do have a rotted out 50C deck from my 1811 (I have a 50" on this 1200) with good hardware. I'll check it out and see if the drive pullys are different. Good idea. Thanks TB

I think the creeper is very handy when mowing, when we first move to our house the grass was 6 inches taller than the hood on the 100 i had at the time but with the creeper in low and the trans in first i was able to take the full deck width without bogging the engine.
