gear vs. hydro for pulling tiller

millertime · Sep 2, 2005

I think its a stretch to say many have had these problem where the hydro tractors could not get up the hills. I want to see the facts before I believe it. I am sure when these things were made the manufacturers designed them to pull as hard as anything else,why else do they sell so many hydro's and keep selling more each year ??? /forums/images/graemlins/smirk.gif

I never heard of a hydro relief valve lifting.... 
It is the hydro relief valve, doing what it was designed to do. It relieves the pressure at a preset pressure.

I still don't believe that they are lifting at the rate or as many as he says. I have ran hydro tractors and bulldozers for years and never heard of one with a hydro relief lifting and you could not get it up a hill etc....

One thing that is brought up every once in while is that dozers, crawlers and other heavy equipment have hydros also. They do have hydro and they do have a very good life cycle. The thing that is different about the hydros in heavy equipment and the hydros in small compact tractors is how heavy duty the hydro actually is and the work cycle that the unit is designed to endure. I am not cutting down or saying that the hydros in compact tractors won't do the job. No fight from me there. They do a fine job in most applications. Just that the hydro in heavy equipment compared to compact tractors is almost like comparing apples to oranges.

I guess you could say the same about comparing gears in a compact tractor as comparing gears in a large tractor or dozer..its like comparing apples to oranges.I worked for 5 years in a rental yard,they rented dozers,tractors,manlifts, forktrucks etc.and compact tractors. The owner slowly phased out the geared compact tractors..why ..because people would ride the clutches and rake the gears on the geared tractors and they ended up in the shop too much of the time, he switched to hydro's and the maintenance on these tractors dropped a lot. The customers were not near as likely to tear up a hydro as a geared tractor and the hydro's were much easier to operate a matter of fact I don't recall a hydro ever have failed. While I was there,some of these tractors would rack up 2000 hours a year and after about 4 years when we got new ones in we would get the hydro's for replacements of the old ones.... the hydro's virtually indestructible,if something failed on the tractor it was something other than the hydro. I spent a lot of time maintaining equipment servicing etc.
I still would like to see all the "numerous posts" talking about these compacts sitting at the bottom of the hills because of the relief valves lifting on them. I never heard of it happening before.

My day gig is working for a GC.. been at the current one for going on 15 years... We see all kinds of repairs... rear ends.. engines.. trannies.. both types. Most of our tranny problems for geared units are clutch/flywheel wear, and the 2-speed going out in the big trucks. As fro the heavy equipment with hydros... they go out and break down just as often as clutches and 2-speeds go out.

I've got a jd 644 loader in a sand pit with a no-go tranny right now.... year ago had a cat 613 pan with a no-go tranny... have hade at least a couple clutch jobs in that time frame, as well as an engine rebuild .. etc. Breakdowns do occour... nothing is bullitproof. Had a volvo loader... engine computer went south... unit wouldn't move.. all hydro controls were electric over hydraulic.. we fixed that thing and sold it as fast as we could get it to an auction.... Probably overall do more clutch jobs than hydro repairs. however.. our mechanic can drop a clutch and reinstall the new one by noon, for 500$ ... a hydro r&r job tripples those numbers and time typically..

Well then.. step away from the sub, grab a cold drink and start searching.... There are tens of thousands of posts to sift thru....go get em! /forums/images/graemlins/wink.gif

I've been here for years.. i remember the posts.. Jerry has mentioned he remembers the posts... you wanna see them.. start searching the umpteen thousand posts that are here.

I'm not knocking hydro's.. or gears.. get what you like and go with it... drivetrains are one of those personal issues just like nearly everything else on a tractor that has an option. I personally don't want to rely on fluid pressure as a motive force on a tractor..

( Well then.. step away from the sub, grab a cold drink and start searching.... There are tens of thousands of posts to sift thru....go get em! ) I've been here for years.. i remember the posts.. Jerry has mentioned he remembers the posts... you wanna see them.. start searching the umpteen thousand posts that are here. 

I have looked and I can't find any. You are the one that said there were numerous post's,so back up what you are saying .instead of making a blanket statement saying there are lots of posts,show me some...you cant is why and you have nothing to back up what you are saying...prove me wrong...type in a keyword on the search and bring some up and show me.
I would never make a statement saying all of these posts existed and then defend myself by telling someone else to go find them..you insist they are there here so find them and prove me wrong..I say they aren't there I can't find any..you say they are there ..well you show me where they are and prove me wrong .

I know the search can be a bit frustrating until you get used to it; only because it defaults to "exact phrase" and "1 week", instead of "and" and "all" like some popular browsers. If it still get's the better of you, just ask for asistance; people around here enjoy spending your money too much to be leading you on a snipe hunt. /forums/images/graemlins/wink.gif

Enjoy. BTW I only tried one combination, based on, I think, your exact needs. /forums/images/graemlins/smile.gif

Spiffy.. I think here is a link that is even more on target. here, in message # 654423 the poster specifically refers to hitting the pressure relief on his hydro sometimes when pulling trees.

TBN link

A message down a reference is made to the 'issue' I had brought up.. about the fellow that had a tractor down in a hollow and it wouldn't crawl out. There were some speculative posts.. then another reference to the 'what's ailing my kubota' post where this question was generated from.

There... took half an hour of searching to pull that up.. I'm done with it.. points proven..( there ARE references in the archives dealing with relief values/hydro tractors... ) for those that want to look for more posts.. better set down.. it's hard to do the searches thru this many posts using specific key words without pulling up 15 pages of posts...

As for now...I'm done in this thread.

Aww heck, you agreed with me! I like both with no real preference overall. You told me to buy both; I'm working on it. /forums/images/graemlins/wink.gif
