Manual SM-2019.....Fully Updated

Compiled to include all service info!

The 420 manual often refers to the plain "40" series service manual for pertinent information.

I have compiled all the referenced material from the "40" manual, and included it within this manual.

I have done this to make this a "complete" service manual.

That is why this manual is so much larger than any other service manual on the market!


New reprint manual with all 702 pages, Measures 8x11 and is 1.50" thick......Very Comprehensive Manual.

Complete Repair, Service and Overhaul Manual for all components of the 420 Crawlers and Tractors.

Shipped out quickly....Orders placed before noon generally go out same day!


This is a bound need to buy a $8 binder just to hold it together!


Color Hydraulic Flow Illustrations.....Most reprint manuals don't have this feature!
