JD4520 e-Hydro not pulling up slopes

[TSO]

Like others have said, Hi range is really only meant for distance road travel. You're not going to have much "uumph" with that gearing. My Massey is similar, though I'm able to sometimes plow snow with my 8' rear blade in Hi if the snow isn't too heavy. When traveling around the area (over to my buddies house) there are a few decent inclines, and in Hi on the road, it'll drop (with cruise on) from around 16 mph to around 13 mph when going up those inclines.

Keep in mind, your 60 HP engine doesn't really equate to 60 HP at the ground the same way a gear tractor does. Your engine is turning the hydro pump, which turns your gears/wheels. HST travel depends on the hydraulic system more than the engine HP, which is why we all say HST doesn't put power to the ground the same way gear does.

Just food for thought...

Try it without load match on. On my 4310 load match will slow my speed way down even if I'm going on flat terrain.

My motion match switch is a bit different than yours, basically just off and on but if it is on I can tell a difference. It's subtle but noticeable.

I use C range for light tasks such as landscape raking, pulling an 8' spike tooth harrow and roller to cover seed. I also use it to move across the fields quickly and for road travel. Most of the time I use auto throttle with the exception of tilling and mowing. For planing and box blade work I use A or B depending on the load.

Thank you all. I'll be out trying a few things tomorrow and let you know.
Has anyone used motion match and do you notice a marked difference b/w long and short setting?
Cheers


oops, just caught the 2nd line of your reply 4310: thanks . Will give it another try on the flat.

Yes, I use the long when using the MMM. I use the short for loader work. I can tell a difference because the tires skid to a stop on the lawn, I know that I left it on short. The motion match is adjustable on my 4310.

 

[4310]

Sorry for the short hijack but.....how do you adjust it on your 4310? I had to break out the owners manual to see if I was missing something but it just says that it's a two position switch. Either short or long.

My 4310 is a 2004 model.

I do not know what kind of ground you guys cut on but with my 4720 and a Woods brush bull on the back I rarely use full pedal even in A range. I have an older model 2007 4720 so have a little less hp (3) and do not have eco PTO so if I want the cutter at the rated speed I need 540 PTO thus higher RPM. But in A range if I went full pedal, most of the time, I would tear up my equipment and would destroy my back and neck. Terrain would bounce the cutter off the ground and I would have bruised hips from the seat belt. I can't imagine cutting in C range. The tractor bounces enough in C range with full pedal when road traveling that it makes me concerned unless I am straight on hardtop not even a gravel road. I have found it works well in the flat when road traveling if the rpm is up but it does not have the ability to put much power to the ground. I use B range for some loader work and heavy loader transport long distance of materials.

Furu,

One of my important reasons for having tractors is for smoothing the properties imo. After working the fields over it is much easier to travel at higher ground speeds.

I guess that would be true if that is what one uses their tractor for (smoothing). I have enough other activities that occupy my time that grading and leveling a field to that point is not one of them. I remember back in the late 60's cutting several hundred acre parcels and they were not smooth enough for those speeds and those were used for grazing and haying. If you have a small acreage that you deal with then I can see it.

I rarely have a use for C range unless I'm running down the road to help someone out. My terrain is very hilly here in WV and I don't like the burning smell of B range climbing hills. A range is slow but I always keep in mind this is a tractor and not a 4 wheeler. I switch in and out of A and B frequently depending on the job at hand. Speedy work on hilly terrain can be a recipe for disaster.

I never really realized how much horsepower a hydrostatic transmission uses up until I got this machine on hills. If all you have operated before was a gear driven tractor, it takes time to get used to the power robbing hydro-drive.
