Hey Guys ,new Cat Owner. Not Sure Of My Year, Can Any Of You Experts, Give Me Any Info On This Old D4.ser#4g2196. I Think It Had A Pony Motor At One Time,but Know Has Direct Start. The Blade Says Latorneu #44,but Is Not Connected To Cable. This Old Cat Runs Luke A "top". It Measures 44 To Mid Tracks.having A Gas Learning How To Drive It.going To Lose The Bus Seat Soon ,to Give Me Mor Leg Room...i Will Be Asking More Tecnical Question Soon Thanx Dave.

Nice ole D4, have fun, and be quick with the hand clutch before it dies when pushing dirt. Enjoy, and welcome aboard. John

My SNID book says they started production in 1936 so it possibly is a 1937 or 1938 or even an early 1939, just guessing.

thanx guys my guess was 1937.what about that la torneau blade?.DID LATORNEAU only make cable operated blades?On this blade it appears to have something cut out,at midline,as if the cable once attached?

ACMOC SE# book shows it as a 1936 RD4 made in Peoria. 1936 SE #'s ran from 1 to 3662. Nice old Tractor.

Good looking RD-4. The blade is definitely LeTourneau, but the hydraulic lift set-up looks home made. Have fun with it!

thank you guys . now i have something to start with.First thing i would like to do,is grease the rollers.are they those ''DIME" size zerks around the rollers?.plus what are the oil cups next to the front of the seat and front of the shift. dave

she is badged a d4,was the rd4 badged that way? i mite have an early d4? or a late rd4? for a seventy year old machine that runs sweet ,she appears to be in good shape.what do i look for other than sprocket wear? How do i test pins/bushing wear?.these tracks seem to be built up at some time. plus what is under carriage.i have allways seen 90% or 70% uc? does it matter on this old rig....i think if she is running and pushing dirt..thats pretty damn good.but i would like to respect her age and do as much maintenance as i can to preserve her. any help appreciated...d

By the wear marks in the root of the sprocket I would say your pins and bushings may be good to go for a while. This means that they are still "in pitch" which means less than 100% wear. The sprocket is worn and the teeth are approaching sharp but I believe this wear is from an earlier time like perhaps before the pins and bushings were turned.

The shiny marks on the sides of the sprocket points is not a classic common wear pattern. This means the sprocket is hitting something. You should have someone watch and see what it is while you operate it. It represents side slop of some sort. Maybe worn rollers.

I can see you have not used it much yet. Run it a few more hours and take some more pictures showing the sprocket and links and post them and we can tell you more.
