Yanmar GT Series – tillage implements of the register: GT-1 TH-A to TH-C with horizontal single-cylinder diesels TF90N to TF150N, 9 to 15 hp, 215 to 252 kg operating weight
The Yanmar GT Series brings together on this collective page the tillage implements GT-1 TH-A, GT-1 TH-B and GT-1 TH-C, which differ within the range solely by engine. Yanmar was founded in 1912 in Osaka and in 1933 was the first to bring a practical small diesel engine into series production; the horizontal single-cylinder diesels TF90N, TF120N and TF150N fitted here descend from that tradition. All three units are light, walk-behind or towed rotary tillers and cultivators for small plots, common in rice growing and horticulture. With the same chassis and frame dimensions, the stepped motorisation from A to C allows graded model upkeep without a complete new design.

The register lists here 3 versions with 9 to 15 hp, operating weights from 215 to 252 kg, a length of 3,055 mm, widths from 1,055 to 1,315 mm and heights from 1,225 to 1,315 mm; all three run on diesel.
Alongside Kubota and Iseki, Yanmar ranks among the leading Japanese suppliers of compact tillage technology, supplying mainly smallholder farms and professional horticulture in Asia as well as an increasing number of speciality-crop growers in Europe and North America, where agile machines for plots with restricted access are in demand.
When buying used, what counts on these small diesel engines is compression, injector condition and the tightness of the cooling fins, as well as wear on the tiller blades, PTO and belt drive; the frame and stub axles are worth checking for cracking from hard ground contact. Spare parts run through Yanmar's agricultural distribution, though older model years are sometimes only available through specialist dealers.
