Hydro or Shuttle

In my experience, hydros have been the most reliable, least expensive to own, have about 2/3 the parts as a shuttle, the same maintenance intervals, but they do have about 3-5 fewer hp due to fluid power loss. You are correct, a dealer replaced clutch will cost about $2500 and are typically needed in 4000 hours of operation (6-8000 for a wet clutch.).

It is pretty rare for a gear tranny to have any problems.

How many folks have hydro tractors with 4-8000 hours of operation for which to compare maintenance costs?

If he is doing landscaping, he will probably be using a front loader. Loader use is HARD on clutchs, especially in tight areas. I would be hard pressed to find a dry cluth loader tractor with 4K hrs AND an original clutch. no loader, definatly shuttle, same gear foward and reverse, much quicker than shuttle reverse = less time backing up and more time doing work.

Just my thoughts and 2cents worth.

Edit:
for tires, the R4's are terrible on snow, would consider turfs, but only if I could pick out the turf tread. Think of a turf tire as a snow tire, more edges to grip + flatter profile for chains (keeps more of the chain in contact with the ground). Turfs on my little tractor will dig a hole, just not as fast as an R1

If you live on hills or have tight places a hydo is best. If you use a bucket hydo is best. Some of my land is hilly and in woods so I went hydo and I am glade I did. One more thing to think about; if you have to work in places that are tight or could be dangerous the hydo gives you way more control, when something dose not feel right just let off of the pedal or back out; it has saved my butt a lot of times.
If you just do feild work go with what ever.

The question at hand is a shuttle model or HST. Shuttle trans are not your daddy's manual trans. Some are closer to an autmotive automatic trans, planetary gears, hyd used to hold/release of the planets and ring gears. Others like my Yanmar has a more traditional arrangement for the gears (constent mesh) but with hyd controlled individual clutches for each gear.

Certainly not in this class of tractor but I still have my 1970 Bolen GT and HST has never had a problem and has been used for plowing and tilling it's full life.

I had planned to get an HST earlier on when I first started looking for a tractor...because everyone raved about them so and I was afraid if I didn't I'd really be sorry. But then the used one I ended up buying (Kioti DK55) had the manual. Actually, they don't make the DK55 at all in an HST, I think the 45 hp ones are the largest that have it,

But anyways, I only have a few hours on it and it's fine so far, don't miss not having an automatic. I've never owned anything with an automatic so far:D

The shuttles on most compacts are like mine, a partial synchromesh, and you have to use the clutch to shift between forward and reverse. These shuttles are a lot more like the manual transmissions of the past than they are like the shuttles on the larger tractors that do not require using a clutch.

I wouldn't think of a syncro trans as being a shuttle model. In my opinion shuttle trans don't require the use of the clutch to shift, even between fwd and rev.

Guess we don't have a common understanding of what SHUTTLE implies.

I think the standard meaning of shuttle is anything that gives you a straight throw between forward and reverse. A hydro-shuttle that doesn't require pushing the clutch pedal is definitely nicer to use, but it's not the only kind of shuttle. On tractors below 60hp I suspect synchro-shuttles outnumber hydro-shuttles probably about 10:1.

Shuttle implies that you shift between forward and reverse, i.e., you shuttle between the two. There are various types of shuttle transmissions. You have some that require the clutch to shuttle between forward and reverse, others allow you to shuttle between forward and reverse or going clutchless on a certain band of gears, and still others allow shifting without clutching throughtout its gears and ranges.

Synchronized shuttle shift transmissions are synchronized between forward and reverse to prevent the raking of gears and to allow shifting on the move; but require use of a cluth. My Mahindra 4110 has a Synchro-Shuttle tranny, and is very user friendly.

You may not conisder transmissions that use a clutch to change directions a shuttle, but the manufacturers do, and have for at least forty years.

If your doing a LOT of shifting an HST is the only way to go.
