Cat 420D Backhoe, 900 hours on the meter, $65K. The clam shell bucket will get new teeth. The backhoe bucket will get rock teeth. Its going to the Cat shop for lube , fluids, and filters. I'm selling the Yanmar tractor. It's been a great tractor but I need a bigger machine.

That's a beautiful machine in a glorious color. What base did you buy it from?

I bought a few generators from fort drum years ago.

That's a beast. Twice the weight of my FEL/Backhoe. Cab looks roomy.

Wonder if that rig can pick up my whole JD 1025 c/w fel? Think it is about 1800-2000#.

I like the color (stealth backhoe) and it's labeled USMC! I think I will name it Sgt Rock.

So I rented a Deere 310SJ several times. Getting it up to the property was a giant PITA. One thing I liked about it was the seat swiveled front to back. No climbing in and out to use the loader or backhoe.

The clam shell front loader on the 310 was very handy. I would dig out a stump on four sides and once all the roots were broken, switch around to the front and use the clam shell to grab the stump and take it to the pile.

Tip: When digging out a large stump on the side of a hill, look at which side should be the easiest and make that the last side to dig. Also, use the bucket curl function under the root and later under the base. The bucket will wedge against the ground and you prevent rocking the whole machine around.

I just had a disease kill 14 Chestnut Oaks. I paid a guy $600 each to cut down, cut up, and haul away. So now I have 14 stumps to dig up. No easy task with the Yanmar tractor.

Tip: If you have rocky soil, hard to dig with a backhoe, buy some rock teeth. AKA Tiger, pointed, or sharp teeth. You need a steel punch or rod that is long enough to reach over halfway the width of the bucket. Punch out one side 2-3 teeth and then the other side. Then install from middle outward.

Probably, it's pickup rating is over 6000#.

Oh yeah!
Mine c/w fel and the 650ish # rear ballast might go 2500#. I could throw in the brush hog rotary mower, rear grading blade and the driveway drag and still be under your capacity.
I ran a Cat 966 articulated loader for a couple seasons with a grubbing rake. My dads business was primarily land clearing, he'd pop the stumps with the Cat 7 dozer (had 2 dozers, sometimes both were runnin) and I'd come along with the big rake pic & shake the dirt out and pile to burn.Tires were almost 6' in dia.
Sunup to sundown x 6 days a week when the ground wasnt froze wasnt much of a life outside of work.

Shes a beaut Clark!

Giving me tractor envy over here.. But I'd need a bigger truck to pull it, and a bigger trailer to put it on.. Sounds like an expensive endeavor

Yeah that!
My local dealer 8mi. away just quoted me $60 to come pick mine up if I want them to service/repair Lil' John. Expect another $60 to return it......
That is probably a bargain at today's fuel and labor costs and its looking like a suitable trailer might be $3K+ and likely too much for my old SUV.

I found a web site that says you can put full synthetic grease on hydraulic cylinders to help the seals last longer.

Not in that application. The grease is is going to collect any dirt and act like sand paper. Those cylinders are the down side to a 4 in 1 bucket.

I also dont believe synthetic grease or normal dino grease would make a difference on that machine, your not greasing high speed bearings.

Was that ram leaking? I replaced the original seals on my backhoe and FEL this year. No hour meter but it's a 1974.

I guess I have the oldest around 1959 Case 420. Paid 4 grand 10 years old. It gets used a bunch. I mounded a bracket in the bucket to attach a snowplow to to help with snow removal.

We're tied, my other Massey is a '59. Gets the most use out of all three. The FEL is easier to use without a backhoe attached and the box scraper keeps my driveway manageable. The skid steer is also a 70 something. 3K for the backhoe, 1K for the '59 and the skid steer was free.

Re. grease on the seals, etc.
Clean rams is a must to keep from eating seals. In downtime or storage spray the seals with a cleaner, wipe off, smear lightly with the grease and wrap a clean rag around.
Prep to run; turn the rag inside out wipe the grease off the seals with the rag, run same up/down the rams to clean and ready to run.

The Cat Tech said it was. From the auction pics both front cylinders were wet.

I think there is a plastic scraper ring before the two rubber o-rings. So the process might be to exercise the cylinders with grease to let the o-rings get lubed and then clean the grease off to prevent the sandpaper effect you suggested.

Agree. Your process sounds good! Thanks!

That's a cool machine. The muffler is custom deluxe.

Yes a plastic scraper seal is first. If it's doing its job then no grease will be getting to the actual seal and one cycle and all the grease would be pushed to the end of the rod or stuck on the scraper.

Picked up at Cat repair shop. PM4 all filters, fluids, grease, new wear plate front bucket, Three hydraulic cylinders rebuilt, rock teeth on backhoe bucket, two batteries, new hydraulic sight gauge, replaced one side glass and hardware, $8000. Basically had them do all the hard stuff I didn't want to do on the mountain.

I took off repair no lights function, probably a relay or fuse. I'll fix electrics myself. Due to age I will replace all relays, only five of them. Fuel gauge showing 1/2 when tank is full. Probably sending unit. Wiper blades need replaced, but I don't plan on working in the rain.

I'll get close up pics next trip out.
