Re: 420 dozer for sale 5hours down the road

Best to trade in your broken down 350C on the one we have with 5,000 original hours and 85% undercarriage!! We are down on crawler projects and had to resort to putting a motor in a Deere 444C wheel loader today. A 420 is a little light for more than willlows and dirt work. They will do the work but...

Re: Jd 350 reverser oil

For use in Alberta Canada our 350’s would not start in cold weather when my dad build access roads across muskeg if THG was used. The 350’s placed rip rap and pushed material for building the roads and the skidders pulled in the timber. Deere oil is expensive that’s why we don’t use it. THG is the e...

Re: Jd 350 reverser oil

ATF works fine in reversers. We used it for better cold weather starting, however in the last 20 years we ran our high horse power widepad loaders with backhoes they only worked in the summer months. We had no failures in the 2 machines due to slipping disks nor any fade in performance when worked t...

Re: To buy or not to buy

To change this to a narrow pad it’s really just a pad swap and remove / install both crossmembers. Worst part would be broken bolts in the frame / crossmember and reverser, which could require engine removal. We have done 5-7, probably a 2 day job for my dad and I counting removing broken bolts. May...

Re: LGP tracks and then some

What you have is most likely a factory wide track machine or conversion. We are down to 3 of them, 2 loaders and 1 dozer all with hoes. Expensive to run in terms of the extension axles, undercarriage, frames and cross members, especially when you up the engines size and horsepower like we did, but f...

Re: Backhoe Fitment on 1976 JD450C

Most loader machines come with the power beyond valve installed on the hydraulic valve and the big hydraulic pump. You will need to acquire a set of Deere 450 hoe hooks that bolt to rear clutch cases with bars that attach horizontally to the loader frame. From there you will need to adapt the case h...

Re: Back hoe attachment

You will need to find a set of hoe hooks. They are specific to 450 / 550 crawlers built before 88.

Re: Back hoe attachment

Any Deere backhoe designed for a Deere crawler will fit. Best model is the 9550 as it is lighter than the 9300 or 9310. We prefer the models with dual swing cylinders Vs the swing box on the 9300. There are lots of older models as well. We have also done conversions on a variety of Case backhoes inc...

Re: final drive

All 350 John Deere undercarriage is compatible across all 350 John Deeres. Same as all 450's up to and including the E series are compatible with one another. I'm sure there are some differences in idler mounting and track adjusters but entire assemblies are compatible.
