Buying Advice HST vs Gear Transmission - which would you recommend on this tractor ?

[4570Man]

Nobody ever has claimed a HST can match the efficiency of a geared transmission. Shear draw bar pull they can match. But the power put to the ground still isn’t anywhere near 3x. He jerked the gear tractor skewing the test.

Along with the commentators on the Youtube, I think most of you missed the point.

He was only showing the HST puts indeed less power to the ground. The fact that the Geared tractor can spin the wheels in High Range and the HST can't, says it all. It just sits there and whines. What's the point for putting both tractors on Low range? Just so see wheels spinning? And yes, Neil said in the comments that he'll do the same test on a hard surface and similar tractors.

For the those that say that you don't do any tractor work in High Range, quite often fields are plowed in 1st gear High Range, where a HST would fall on its face with a lot of noise behind. Another one is the picture I'll add, would an HST tractor pull this trailer on a hilly road without having to fully stop and messing with ranges? Definitely not. The Gear tractor just downshifts on the move a gear or two.

That load of logs isn’t something I would pull with my tractor on hilly terrain. Ever

Funny that you keep mentioning that. Maybe you should watch the video again. The one time he jerked the clutch, the tractor was still in 2WD and he then proceed to engage 4WD and feather the clutch properly to achieve the 3000 lbs+ he did. This number was not jerking the tractor like you mentioned.

Yeah, but it's something done quite frequently over here. Small loggers and firewood sellers use 40 to 50 HP tractors and have to road the tractors and trailer fully loaded a lot.

In my opinion from what I have read very few of the tractors written about and owned by posters on this board are worked hard and long with drawbar loads.
The majority are used for mowing and loader work, with some limited rear mounted blade work.
They are not pulling heavy loads considerable distances frequently.
And just to clarify it in my mind untill you are in the lower third of your gearing and scratching for traction you are not pulling hard or
hauling a load that requires going thru your gears to get to speed and downshifting for grades or turns.

The harder a tractor is worked on the drawbar the less desirable the HST becomes and the efficiency of the gears dominate.

The ultimate test would be to have 2 same make model tractors with only the transmissions being different.
Link them firmly back to back drawbar to drawbar and enjoy a pulling contest!

To make it more interesting vary the surfaces, asphalt, concrete, grass etc and LOL, mud!
Then sit back and take bets.

Oh and weigh each (on calibrated scales) B4 proceeding and add ballast to keep the game fair.
Advertising sponsorship could be sold to to tire manufacturers and fuel people to support the effort.

Exactly, the test was fair.

I think Oldpath just likes to :stirthepot:. It's fun to watch though. :thumbsup:

The operator knew he could break traction in low range with both and this is why the test was used in high range to show the transmission limits. I have both types in under 30hp tractors. If I have excellent traction in low range the hydro trans slips and the wheels don't break. The gear tractor always breaks traction on the tires and this is with a 800 pound heavier tractor with little worn tires. Maybe this doesn't play out with larger HP tractors.

He did the same with the hydro but when he put the petal to full the hydro just whines and whines and whines,,,,,, when he finally let the clutch out all way on gear, the tractor spun the tires in high range and the number show the results. @1:42 the hydro numbers was 1119, @3:12 the gear numbers was 3066 and the tires are spinning........
