JD 4210 - bogging down ?

[Spanner]

I personally don't like the "long arrow" mode at all in the little I've driven a 10 series. It make the transmission feel like it's being controlled with a rubber band. The short arrow is much more responsive.

Which is the whole point and why they give you a choice.

Long/Short Arrow is the 'Rollout' which is the time taken for the tractor to coast to a halt after you take your foot off the pedal (in either direction).

A Long Rollout is preferable on fine turf where a higher braking force (Short RO) could damage/tear the turf surface. eg. Golf Course. (i.e. if you take your foot off the pedal at speed the wheels would lock up and skid instead of coasting to a graceful halt.) Try it on grass.

The short RO is more desirable when on higher tractive grip surfaces such as concrete/tarmac.

I understand what it's for but for me it's solving a problem that doesn't exist. It's great if it works for you. Mine has mechanical linkage and it doesn't tear up the grass stopping and starting.

Thanks everyone, I've read the manual and tried some different settings. My application really is what I would consider light mowing and the manual states that's OK in range C. However, I think it's too fast and I get a better cut in B. Plus you guys are the true experts, so I'll be mowing in A or B. At a lower RPM and speed it does seem to bog down less, though I still feel a loss of power, I did not get the indicator lights. I think I prefer the longer roll out. Still learning as I move up from my old BX2200. Thanks for the help.

I never thought to ask you if you made sure the loadmatch feature was on... that's intended to make the C-->B, or B-->A ratio changes so you don't lug the engine. Even with loadmatch on and 30hp at the PTO I can drag in taller grass with a 5 ft shredder, so where the 4210 only spins at 22hp, you'd really feel it with the feature disabled.

Potentiometer is basically a position sensor. Typically on a 0-5v range.

I've had a 4210e for 15 years since it was new. While not the most powerful unit in the world, it has never bogged while mowing grass in A or B range - w/o Loadmatch on. The eHydro was replaced when the unit was new due to some issues. It is possible to have the engine bog down in deep sand - but everything has a limit.
