One day at the last Christmas when we were sowing, we spent one day with our friend Helio Catalán in his neighbor field, who was testing a new Kubota M8540 Narrow (Kubota España lent him this tractor to carry out a real test without any terms) as you can see in this viedo. Thanks to this, we could spend a few minutes to see it and how he crushed vine shoots with the Comage TRS-3H-VS 1500 crushing machine. We visited him a year ago in the same vineyard, but that time he was picking up vine shoots with a cage to burn them after that. Helio published an extensive report about this tractor (part I and part II) in his blog, but we would like to describe more information about his jobs in the vineyard.
The most important features of Kubota M8540 Narrow are:
- Kubota V3800-Di-TE3 4V engine with 3,769cm3 and 4 cylinders, E-CDIS direct inyection system and turbocharged.
- Maximum power: 76HP.
- Tank capacity of 78 litros.
- Nº of gears: 15/15.
- Soft powershuttle reversing transmission.
- Max. lift capacity at ball ends: 2.300 kg.
- PTO: 540/540E.
- Integrated and sound-proofed safety cab with low noise level.
- Pump flow rate of 61 l/min (open center) and 2 hydraulic remote valves.
- Maximum speed: 37km/h.
- Trelleborg TM700 tyres: 380/70R28 and 280/70R18.
Regarding the crushing machine, it highlights because it has a hydraulic supply to avoid stones and it doesn't has clogging because it can rotate in both directions. In FIMA, we were talking with the boss of General Agrícola (a company which manufactures this crushing machine) about this machinery and he told us that it can capture and crush a pen... we will do this test the next time!. This crushing machine can cut vine shoots and, besides, it can tear them (it is another important feature, in this way, vine shoots can rot easily).
As for Kubota M8540 Narrow, we couldn't test it but we could listen its fantastinc engine sound, see its reduced steering angle with the Bi-speed system activated and the fantastic soft powershuttle reversing transmission (we think these three characteristics are what identify Kubota). On the other hand, this tractor has a lot of things which can be improved, e.g., its gearbox because it doesn't have the basic Hi-Lo system and the gear shift is rather crude. The tractor gets 540 revolutions of P.T.O. (with the 540E configuration) when its engine is working at 1,826 r.p.m... we didn't like this feature because we think it is too high, isn't it?
Finally, the price. All good or bad features are justified by the tractor price. If it is appropriate, the tractor will be a good option for farmers. Otherwise, if it is expensive, we think it will not a good idea to purchase. In this case, we consider the price (we think it is indicative) is very expensive regarding features of the tractor.
