Iseki TU1400-TU1601: hydraulics, PTO, and implements

Iseki TU1400-TU1601: hydraulics, PTO, and implements

These systems are identical between the 00 series (TU1400/1500/1600) and the 01 series (TU1401/1501/1601).

Suitable for the entire series: Iseki TU1400, TU1400F, TU1500, TU1500F, TU1600, TU1600F, TU1401, TU1401F, TU1501, TU1501F, TU1601, TU1601F.

Lifting mechanism

With the position control lever, you set the implement to any desired height between the lowest and highest position, and it stays there — handy for maintaining a constant working depth with a rotary tiller or bed former. The separate slow return valve independently controls how quickly the implement descends: fully closed locks the hydraulic pressure completely, so a mounted implement cannot sink during transport.

A 3-point lifting mechanism (JIS category 0) and a tow hitch are listed as options in the factory manual — so not every unit has this as standard from the factory.

PTO (power take-off)

Never engage or disengage the PTO while driving under high engine load, and always put it in neutral before starting the engine (safety feature).

What can you realistically do with 14 to 16.5 hp?

The stated engine power (14 hp for the TU1400/1401, up to 16.5 hp for the TU1600/1601) is the maximum engine power — not the power available at the PTO shaft. Due to drivetrain losses, expect around 80-85% of that at the power take-off. For this weight class (490-565 kg), that means in practice:

• Rotary tiller/cultivator up to approx. 80-100 cm working width: excellent, this is the classic job for these tractors.
• Flail mower/topper mower (light, up to approx. 100 cm): quite doable, pay attention to sufficient PTO speed (choose the 1229 rpm setting if the implement requires it).
• Small rotary tiller or bed former/ridger: suitable for vegetable garden and border maintenance.
• Ploughing: possible with a light single-furrow plough in light soil, but this is not a strong point for this weight class — expect wheel slip without front weights.
• Front loader: only with light loads; this is not a loader tractor. With a 4WD version with front loader, always pay attention to the increased front tire pressure (1.5x standard).

Always distinguish power (PTO/engine power, for rotating implements) from pulling power (for towing/ploughing) — with these light tractors, the tractor's own weight is mainly the limiting factor for pulling power, not the engine power.
