Questions You Should Know about Yuchai Excavator

Any one own one, or ran one? Im looking at a YC35 with a cummins engine. I live in a "remote" part of canada. I know cummins mechanincs but as far as hydraulics go, how readily avail are they? Also has anyone in canada dealt with JDB equipment? I was looking at a JD 110 tlb but like the idea of seperate hoe/ Utiliy tractor better. Also a track hoe is easier for cleaning out my creek.

So if anyone has experiance,owns one please fill me in on them!

thanks! Hi,

I used to be a dealer with JDB equipment to sell tractors (have gotten out of it, nothing to do with them, personal reasons) and they were always good to deal with.

As far as the Yuchai's go, they seem to be good machines, I have never seen one personally, but from what I hear getting parts is a problem. Around here their prices are not that great for the chance you are taking on an unknown machine.

Just my two cents worth, good luck. I have not long sold my YC35-7 Yuchai . It was a great little machine , i did'nt like the rubber tracks tho , they were always falling off , no matter how tight they were . Parts are'nt really a problem as the engine is Cummins , the pump , drive motors and slew motor are all Japanese . Pull the radio speakers out and put some insulation behind them . The speaker cones are the only thing between you and the engine noise . If you are going to run a mower , you must run a hose from the Cadmium coloured bung on the valve body under the floor too the blade control valve to get enough flow . Also tell them from the get go , that if the alternator light comes on with all the lights and air con turned on , you want a 75 amp alternator fitted . The Cummins comes with only a 35 amp for stationary use and with the lights and air con going it can't keep up . This is the only picture i can find at the moment . I traded the truck and the Yuchai on the 23 tonner , we unloaded the big girl and then loaded the truck and Yuchai on the trailer . How many hours did you put on it? Did you ever have any problems with it? did you have a quick coupler on it? Also what kind of mower did you have for it... My creek maintenance wont need a hoe to mow. I can get that with my tractor, I just need it for beaver dams. dead fall ETC. Why did you sell it? and what did you pay for your 35? Sorry for all the questions, but your the first person Ive found to run or own one. Its a hunk of money to throw at something you have no clue about.

Pilot Controls

Pilot controls use oil pressure via hand and and foot controllers to activate the main control valve that divert oil into the hydraulic cylinders to make them move. They are much easier to move than controls directly connected to the main valve therefore providing a softer feel
when operating a mini excavator with much less operator fatigue.

 Swing Boom

A swing boom on a mini excavator allows the operator to move the boom to the left and right while keeping the upper structure in the same place. It helps the operator dig around objects, dig on angles and when used in conjunction with the slew function it places the bucket to outer edge of the tracks and lets the operator dig close to fences and walls

Zero Tail Swing

When a mini excavator is described as having Zero Tail Swing it refers to the design of the upper structure in relation to the underneath track frame. Zero Tail Swing means the rear or back of the excavator does not protrude past the outer edge of the tracks. The benefit is that when working in tight areas the operator knows they can swing or slew the machine left and right knowing the rear wont hit anything.

Expanding Tracks

Mini excavators with expanding tracks means that the width of the under carriage can be varied or expanded in and out. This is particularly useful for mini excavators trying to gain access to properties through narrow gates and paths. Once the machine is through the narrow gap the tracks can be expanded out again to gain extra stability for digging.

Buckets

Buckets come is many different shaped and sizes but generally there are 2 main types of buckets used on a mini excavator. GP or General Purpose buckets are used for digging, they are fitted with teeth and are good at breaking up hard ground. The 2 main sizes buckets used on mini excavators are 300mm wide for trenching and 450mm wide for footings.

Mud buckets are usually much wider than GP buckets and don’t have teeth fitted to the cutting edge. They are excellent for scraping and smoothing the ground and for moving larger volumes of loose material.

Tilting Mud buckets have hydraulic rams built into the bucket which allows the operator to “tilt” the bucket left and right. The best example of using a tilting mud bucket is being able to dig perfectly horizontal when the excavator is leaning on a angle. They are usually
connected the bi-directional piping with quick connect couplers.
