The Novotný H512 Harvester presents a low impact approach for the effective harvesting of thinnings

Strojírna Novotný s.r.o. is a traditional manufacturer of agricultural, forestry and construction machinery based in Hrabová, in the Olomouc region of the Czech Republic. This engineering company was founded in 1991 and employs over 100 workers between their two production plants.

In addition to skid-steer loaders, B861 and B961 which are widely used in agriculture and construction, Novotný manufacture minimal impact thinning forestry forwarders. They currently offer 3 types of forwarders LVS 511, LVS 520 and LVS 720, which differ in size, engine power and loading capacity. 

Up until last year they have avoided the harvester segment of forestry machines due to the availability of small harvesters from other manufacturers. However, after lengthy discussions with their customers, it became clear that there was a lack of availability of compact 8-wheel drive thinning harvesters with a long reach crane and a powerful harvesting head for processing both coniferous and deciduous thinning.

Novotný have spent over 2 years developing their first thinning harvester, the Novotný H512

The Novotný H512 protype was finished mid-2023 and after much rigorous testing it was finally released for sale in 2024

I saw the Novotný H512 harvester last June and could see the advantages of using this lightweight, narrow wheelbase thinning harvester, the rear bogies track the front bogies so there is no need to worry about any damage to the remaining crop. The front axle is fitted with a bogie lift which increases the turning circle of the harvester.

It has the option of 400mm tyres with a width of just 1.86m and on 500mm tyres (recommended) it is still only 2.06m wide, tracks can be fitted to both bogies to further reduce ground pressure, or wheel chains can be used for additional traction on firmer soils. The overall length is 6152mm with ground clearance of 450mm, transport height is 2880mm. It is a well-balanced harvester with good weight distribution which offers excellent stability even when harvesting at full reach.

Power is delivered by an Iveco 3.5 litre 75 hp four-cylinder engine using a DPF particle filter without any Add-blue, this is a proven engine which Novotný use with their LVS 511 forwarder and skid steer loaders.

Rexroth supply the hydraulic systems for drive and working and it is the same tried and tested components used in the LVS 511 forwarder which are extremely capable even in demanding and steep conditions.

Traction force is 77kN and the harvester can travel at speeds of up to 18km/hr. The working hydraulics have a 100cc pump that feeds the harvesting head, the hydraulic tank capacity is 140 litres with two hydraulic oil coolers.

There are two parallel crane options from MOWI, the 6.5m reach P50 or 7.5 m reach P610T with both having a lifting force of 5500kg at full reach. The main lift ram has a damper at the end position for smoother operation and the crane base tilts to 18°.

The harvesting head is from the Finnish company Kesla Oy and is the RH16 model, this is an efficient head for harvesting both conifers and hardwoods. The 16RH is the market’s lightest professional harvester head which is equipped with four moving delimbing knives and one fixed with multi-stem functions. It’s specifically designed for the integrated harvesting of timber and biomass. Feeding speed is up to 4m/sec via the two feed rollers and can be equipped with the proAX feature which is a shear used for cutting the thin parts of the stem thus saving the chainsaw chain.

The electronic system checks all the operating data of the machine, this allows operators to set the speed of each individual function of the crane. Novotný use the proven measuring system Xlogger from the company Technion.

This also allows you to individually set the functions of the harvester head to suit each individual operator, the system communicates in all languages and is straightforward and user-friendly.

Safety and comfort are two vital factors and Novotný have gone over and above to address both. The cabin has been assessed and approved to ROPS, OPS, FOPS standards, it is a spacious, air-conditioned, and well soundproofed environment with outstanding visibility.

An air-suspended, heated seat is fitted as standard, and the machine has several LED lights that reduce eyestrain even in the darkest, densest thinnings.

 Novotný have kept the construction of the harvester remarkably simple, sturdy and based it on the proven concepts of their forwarders and kept their price structure of the harvester fair compared to the competition. Harvester Novotný H512 – Loader.cz
