Hi folks,
I'm going to discuss the basics of 400 series tractors and note the major differences between 400 and 200 series tractors of the same era.

So, now onto the 400 series tractors! The 400 series were a 442, 444 both Kohler K series engine powered with engine changes similar to what the 200 series tractors experienced. Case installed Onan twin cylinder engines of earlier models to the B43m and B48M engines that were used in later models. The 442 was discontinued but upgraded to a 444 with the 14HP Kohler K series engine. The narrow hood was used on Onan twin models, the hood had minor changes to include a hood scoop for a short time. I always liked the hood scoop and would have been happy to see it included onto the wide hood in the Ingersoll line, but it didn't happen!:sad:
With the introduction of the 448 model, the tractor frame was elongated in the area between the steering tower and the seat support. This was good for tall operators and old short fat guys like me so the steering wheel didn't rub on our bellies as we operated these tractors!:clap:
Subsequent production of 444 and 446 models followed suit with the 'long frame'.
Early Onan twin powered tractors had 16HP BF-MS model engines that were later replaced with 16HP B43M, short stroke and 18HP B48M long stroke engines. The 226 and 446 have a single flow hydraulic oil cooler, the 448 has a multi-flow, higher capacity hydraulic oil cooler. Similar to the 200 series tractors, the PTO clutch progressed from the Shim Adjust clutch to the EZ Adjust clutch, more info about these clutches will be coming.
The later model 226, 446 and 448 have the integral travel control/holding valve and 1988 models have the 3 light panel with a hourmeter. The 3 light indicator panel included a neutral indicator, a charging system indicator light and a PTO on indicator light. The ammeter had been removed and replaced with a battery voltage sensor that operated the light. The neutral light and its switch and the OPTO light and its switch are involved with with the neutral safety start circuitry. This system has continued into the 3000 and 4000 series tractors to date but with some switch location and function changes. When dealing with mid to late 1980s 226, 446 and 448 models, it is imperative that one knows the PIN number of their specific tractor in order to properly troubleshoot, diagnose and order the correct repair parts! Another minor change was from the low back seat to the high back seat which I found to be more comfortable for this old fat guy!LOL :geek:
The 400 series tractors have the 16" diameter 'tall' rear wheels/tires with 8.00 X 16 two ply turf tires but retain the same front wheels/tires as the 200 tractors. This means that the front axles and spindles are different between the 200 and 400 tractors. Also the rear fenders on the 400 are taller to go over the 'big' rear wheels/tires. Fenders have also evolved to cover more of the rear tires of both models, some folks like the newer fender design, some folks don't! Oh well!:clap::cry::geek:

I need to do some wrenching on equipment and stop one fingering on the keyboard for a while, so I'll be back later in Mac's Corner with 3000 and 4000 series tractor info!!:lol::mechanic::geek:

OK, Mac is back earlier than expected as it is 48 degrees in my garage and I just turned the heat on which will be a while before the heater does its job!
To recap the major differences between 200, 400, 3000 and 4000 series tractors:
200 and 3000 tractors have 5 bolt rear wheels/axle flanges, small wheels.
400 and 4000 tractors have 6 bolt rear wheels/axle flanges, big wheels.
200 and 3000 tractors have a higher speed hydraulic drive motor than 400 and 4000 tractors.
400 and 4000 tractors have a slower speed hydraulic drive motor than 200 and 3000 tractors.
All 200, 400, 3000 and 4000 tractors have the same size front wheels/tires. Bearings have a 3/4" ID.
200 and 3000 tractors have front spindles that are 3/4" diameter and have the low height front axle.
400 and 4000 tractors have front spindles that are 1" diameter and are reduced to 3/4" diameter for wheel installation. They have the high height front axle.
I'll be back!:geek:
