Autonomous Mower vs. Rotary Mower: Effects on Turf Quality and Weed Control in Tall Fescue Lawn
No full textAutonomous mowers are battery-powered machines designed for lawn mowing that require very low human labour. Autonomous mowers can increase turf quality and reduce local noise and pollution compared with gasoline-powered rotary mowers. However, very little is known about the effects of autonomous mowing on encroaching weeds. The aim of this research was to compare the effects of an autonomous mower and an ordinary gasoline-powered mower on weed development in an artificially infested tall fescue (Festuca arundinacea Schreb.) turf with different nitrogen (N) rates. A three-way factor experimental design with three replications was adopted. Factor A consisted of three N rates (0, 75, and 150 kg ha−1), factor B consisted of two mowing systems (autonomous mower vs. walk-behind gasoline rotary mower equipped for mulching), and factor C which consisted of four different transplanted weed species: (a) Bellis perennis L., (b) Trifolium repens L.; (c) Trifolium subterraneum L.; and (d) Lotus corniculatus L. Of these, B. perennis is a rosette-type plant, while the other three species are creeping-type plants. The interaction between mowing system and transplanted weed species showed that the four transplanted weed species were larger when mowed by the autonomous mower than by the rotary mower. The autonomous mower yielded larger weeds probably because the constant mowing height caused the creeping weed species to grow sideways, since the turfgrass offered no competition for light. N fertilization increased turf quality and mowing quality, and also reduced spontaneous weed infestation. Autonomous mowing increased turf quality, mowing quality, but also the percentage of spontaneous weed cover

Steel Work Design and Analysis of a Manual Lawn Mower
No full textAbstract: This work presented the design and construction of a manually powered lawn mower as well as the stress analysis of the blade. The solid model of the lawn mower design was done using Solid works software. The materials utilized for the construction were selected following standard material selection processes. The required cutting speed was achieved by proper gear arrangement which transferred the rational motion of the wheels to the blade, consequently increasing the speed by about 300%. The average cutting capacity of the lawn mower is 62.48 m2/hr. The stress analysis on the blade using the simulation tool of the solid works software gave a maximum von mises stress that is 252 times less than the yield strength of the blade material. Also, a maximum deformation of 0.00271mm obtained from the analysis is quite infinitesimal hence, the blade can withstand both stress and deformation resulting from the cutting operation.
Keywords: grass, lawn mower, blade, cutting speed, cutting capacity.

Autonomous rotary mower versus ordinary reel Mower-effects of cutting height and nitrogen rate on manila grass turf quality
No full textHigh-quality sports turfs often require low mowing and frequent
maintenance. Sports turfs often consist of hard-to-mow warm season turfgrasses,
such as zoysiagrass (Zoysia sp.) or bermudagrass (Cynodon sp.). Although autonomous
mowers have several advantages over manually operated mowers, they are not
designed to mow lower than 2.0 cm and are consequently not used on high-quality
sports turfs. All autonomous mowers are only equipped with rotary mowing devices
and do not perform clipping removal. An ordinary autonomous mower was
modified to obtain a prototype autonomous mower cutting at a low height. The
prototype autonomous mower was tested on a manila grass (Zoysia matrella) turf
and compared its performance in terms of turf quality and energy consumption with
an ordinary autonomous mower and with a gasoline reel mower. A three-way factor
experimental design with three replications was adopted. Factor A consisted of four
nitrogen rates (0, 50, 100, and 150 kghaL1), factor B consisted of two mowing
systems (autonomous mower vs. walk-behind gasoline reel mower with no clipping
removal), and factor C consisted of two mowing heights (1.2 and 3.6 cm).
Prototype autonomous mower performed mowing at 1.2-cm mowing height
whereas ordinary autonomous mower mowed at 3.6-cm mowing height. The
interaction between the mowing system and mowing height showed that the turf
quality was higher when the turf was mowed by the autonomous mower and at
1.2 cm than at 3.6 cm. Autonomous mowing not only reduced the mowing quality,
but also reduced the leaf width. Lower mowing height induced thinner leaves.
Nitrogen fertilization not only increased the overall turf quality, reduced weed
cover percentage, but also reduced mowing quality. Autonomous mowers also had
a lower energy consumption if compared with the reel mower (1.86 vs. 5.37 kWh/
week at 1.2-cm mowing height and 1.79 vs. 2.32 kWh/week at 3.6-cm mowing
height, respectively). These results show that autonomous mowers can perform low
mowing even on tough-to-mow turfgrass species. They could also be used on highquality
sports turfs, thus saving time as well as reducing noise and pollution

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textEnvironmental maintenance activities on AAU gallance is a routine activity that
is done continuously,One of these is the activity of cutting grass. The activity of cutting
grass was done using a mower.The magnitude of the activity of cutting grass at a area,
hanging from a lot of activity mower that occurs in the area.The displacement activity
of the mower is stochastic events.Where the displacement activity mower only visual
course, referring to the data has not been done scheduled.So that the result of cutting
grass has not been evenly.
A method of markov chains is a method that studies characteristics of a variable
at the present based on the their characteristics in the past, that which is purposed to
predict characteristics of variables such in the future.From first data known that the
displacement activity mower that occurs only dominate a certain area course.This
provides a description that of cutting grass happened has not been evenly.By using the
method markov chains, then a chance occurrence of cutting grass predictable for some
period to the next until it reaches the condition of steady state,condition in which a
chance occurrence of cutting grass in the period already fixed or not changed
again.From data steady state condition obtainedturns activity of cutting grass not much
undergo a change as the first conditions.This indicates that for some period in the future
the activity of cutting the grass still haven't done evenly.
Based on research done it can be concluded, cutting grass in the area A, B, C,
D, I, J and K supported with 1 unit large tractor mower takes 2,06 hours a day and 7
unit pickaback mower takes 1,87 hours a day. Cutting grass in the area E, F, L, O
andPsupported with 1 unit medium tractor mower takes 2,02 hours a day, 1 unit push
mower takes 1,5 hours a day and 4 unit pickaback mower takes 2,03 hours a day.
Cutting grass in the area G, H, M and N supported with 3 unit mini car mower takes
2,05 hours a day, 1 unit push mower takes 1,88 hours a day and 2 unit pickaback mower
takes 1,52 hours a day
