Porovnání sběracích lisů při sklizni píce
TUREK, Tomáš
This work deals with the comparison of two round balers with a variable baling chamber (Claas Variant 365 rc pro) and with a variable baling chamber without the possibility of pressure configuration (Krone Comprima F 155 XC baler), for two private farms with the same focus but different machines. The main comparison lies in area performance, quality of work and economic efficiency. The comparison took place on a pre-prepared plot. Each press had half the land.

Comparison of quality of work round baler
Bulva, Miroslav ; Novák, Petr (advisor) ; Mašek, Jiří (referee)
The thesis is focused on comparing the round baler with variable bale chamber. The press Vicon RV 1601 OC14 was compared with press Welger RP 435 Master. The evaluation was conducted from three perspectives. The first was the construction of the machine. The second was economic and the last one was the quality of work. Furthermore comparing was done per the performance, the cost of molding, packaging and simple analysis of investment and operating costs. The quality of the design was better with the press Welger. This press was measured to better results in bale density per hundred percent dry matter with straw 98.13 kg.m-3. Greater hourly output during molding were measured on the press Welger. From an overall perspective was evaluated press Welger better.

Comparison of pick-up balers for fodder harvesting.
KOČÍ, Vojtěch
This thesis for bachelor degree focuses on a comparison of pick-up round balers, one with a variable bale chamber (baler John Deere 580 with cutting) and one with a constant bale chamber (baler Krone Rond Pack 1250 MultiCut). The two balers were compared in respect to the quality of cutting, bale density and haylage quality. Other compared parameters included capacity, costs of baling, packaging, loading and transport of baled fodder, analysis of costs per 1 kg of fodder and simple analyses of investment and operating costs. The quality of haylage was better for the JD 580 baler and it was classified as excellent. The baler Round Pack 1250 produced better values of bale density: 221.09 kg.m-3 for hay, 428.57 kg.m-3 for haylage and 173.46 kg.m-3 for straw. Hourly baling capacities were 8.12 t.h-1 for hay and 11.55 t.h-1 for haylage. The baling costs were 104.2 CZK.t-1 for haylage and 210.36 CZK.t-1 for hay. The costs per 1 hectare were 376.6 CZK and the costs per 1 kg of haylage and hay were 0.539 CZK.kg-1 and 0.606 CZK.kg-1 respectively.
