The new E Series consists of two models, the 38.5 HP 1739E and the 34 HP subject of this test, the 1734E. Unlike 1700 Series Premium models which are powered by Mitsubishi engines, E Series models get Shiabura N843T-F powerplants. But like the Premium Series, the rest of the tractor is all-Iseki. The Shiabura engines are three-cylinder mills that displace 1.5L (91.5 ci), have low-pressure indirect injection, and are turbocharged. Final Tier 4 (FT4) emissions requirements are met through internal exhaust gas recirculation (iEGR) and a regenerative diesel particulate filter (DPF). Rated output comes at 2600 RPM, and in the case of the 1734E, power take off (PTO) horsepower is 29 for gear transmission models and 27.2 for hydrostatic equipped tractors.
Manual transmission models have three forward and one reverse gear with three speed ranges (9F / 3R) and feature independent rear PTOs (a mid PTO is not an option for E Series tractors). Hydrostatic (HST) tractors also have three ranges and come with transmission driven PTOs with overrunning clutches. A nod to the cost-cutting gods or, according to Dan Huff of Big Boy’s Toys in Pomfret, Conn. and our gracious host, good news for those with big feet is the treadle-style pedal that HST E Series tractors utilize. Either way, operators must use a left foot clutch pedal to engage/disengage the PTO.
