Chain Drive

[unclehan]

Are there any tractors, harvestors, tillers, or any agricultural machinery that uses chain drive as one of its component?

Thanks

Chain drives are used on some tillers, many hay rollers, and several other attachments. A couple of older tractors were chain drive, but that is long past.

My 1950 Case DC (and the SC and LA's) are chain drive from the differential shaft to the rear axle. It's (huge) 120 pitch chain and a not too difficult to replace. One for the left, one for the right. Case's logic at the time was the chain would distribute the load over many teeth where on a gear to gear drive only has two or three teeth taking all the load. I only had to replace one chain (on my 55 year old tractor) and that was due to a failure of the connector link.

Case carried that design all the way through the 30 series Cases up to the 930 (80-90hp) and maybe the 1030 (100hp).

It seems chains are a lot cheaper than shaft drives, so how come it's not widely used?

Most tractors have the differential/final drive mated to the trans. so no drive shaft per say is used. Also as Case found out, 90-100hp is right at the limit for chain reliablity. The 70 series and everything after the 30's featured an all gear drivetrain to my knowledge.

Motor Graders and Skid steer loaders use chain in their final drives… and all Track equipment use ‘chain’ as one of its components, the track itself is a large chain with pads attached /forums/images/graemlins/grin.gif. KennyV.

Also used because of the effecient transfer of power, but some would want you to believe they are bad, bad, bad, when used to drive a tiller. /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif

Think tere is a chain somewhere in the transfer case of my truck. Its a little over 90 HP.

Sears used to have their bottom basement lawn rider with an exposed chain drive.
Extremely Cheesy! And, a constant state frustration and melancholy for the user.
I had one, used it a year and sold it for $50.00 more than I paid for it. This was many moons ago. I doubt if they still use that drive system.

Yep a lot cheaper to replace a chain than a gearbox too.
