A Complete Guide on How to Choose a Brush Cutter and Maintenance Tips
By PackForge Technical Team, Faridabad · 6 min read
Grass on the bunds, weeds between orchard rows and bushes along the boundary grow back every season, and clearing them with a sickle takes days of bending. A brush cutter does the same work standing up, in a fraction of the time. The catch is that a machine which suits flat bunds can be tiring on a slope, and a blade that clears woody growth is the wrong tool for soft grass. This guide explains the types, the figures that matter, how to choose and how to keep a brush cutter running through the season.
What Is a Brush Cutter?
A brush cutter is a small petrol engine that spins a cutting head at the end of a long shaft. The operator carries it on a harness and swings the head across the growth to be cleared. It can carry a metal blade for tougher weeds and light bushes, or a nylon trimmer head that whips through grass. On PackForge, the cutting width is about 255 mm with the metal blade and about 430 mm with the nylon head on both models.
It is not a lawn mower. There is no deck or wheel to set the cutting height: the height depends on how the operator holds the head. That is why a brush cutter is used where a mower cannot go, on bunds, canal banks, uneven ground and between trees.
Why Use a Brush Cutter?
- Faster clearing of grass, weeds and bushes on farm bunds, orchards and plantation rows.
- Less bending than a sickle, because the operator works standing.
- Reach into places a tractor or mower cannot: slopes, terraces, canal banks and boundaries.
- One machine, two heads: the nylon head for grass and the metal blade for tougher growth.
- Plain petrol on the 4-stroke models, so there is no oil-petrol mixing in the field.
What Are the Types of Brush Cutters?
Side Pack Brush Cutter
The engine sits at the top of the shaft and a side harness spreads the weight across one shoulder. The 31 cc side pack brush cutter uses a 4-stroke 139F engine of about 0.7 kW, holds about 0.65 litre of petrol and weighs about 8 to 9 kg. It is the practical choice for small farmers, gardeners and village grass-cutting work on level ground. ₹10,250 + ₹1,845 GST.
Backpack Brush Cutter
The engine rides on a padded backpack frame and a flexible shaft drives the head, so the weight sits on both shoulders. The GX35 backpack brush cutter uses a 35.8 cc 4-stroke GX35 type engine of about 1.0 kW and weighs about 10 to 11 kg with the frame. It suits slopes, canal banks, tea and coffee estates and uneven ground. ₹11,810 + ₹2,126 GST.
Cutting Heads
The nylon trimmer head is for grass and soft weed. The metal blade is for hard perennial weed and light undergrowth. Neither is meant for woody stems thicker than the blade can take: those stall the engine, and on the backpack model abuse breaks the flexible shaft first.

Tree branches and logs are chainsaw work: see the 22 inch petrol chainsaw. Loosening soil between rows is power weeder work, not brush cutter work.
Understanding Brush Cutter Specifications
Engine size and power tell you how well the cutter holds speed in thick growth: 31 cc and about 0.7 kW on the side pack, 35.8 cc and about 1.0 kW on the GX35. A bigger engine does not protect the shaft from abuse; it only gives more margin in heavy cover.
Cutting width is how wide a strip each swing clears: about 255 mm with the blade and 430 mm with the nylon head. The nylon head clears grass faster; the blade deals with tougher growth.
Fuel tank decides how long you work between refills: about 0.65 litre on the side pack and 0.63 litre on the GX35, both plain petrol.
Weight is what the operator feels by the afternoon: about 8 to 9 kg for the side pack and 10 to 11 kg for the backpack with its frame. The side pack is about 2 kg lighter, so on level ground with short sessions it is the simpler machine.
Features to Look For
4-stroke engine – runs on plain petrol and needs no mixing, which removes the most common fuel mistake in the field.
Harness that adjusts to whoever wears it. If several workers of different heights will share one cutter, strap adjustment matters more than engine figures.
Both heads supplied or available, so the same machine can switch between grass and tougher weed.
Guard over the head, kept fitted at all times.
Spares on hand – blades, filters, carburettors and pull starters are stocked for every model PackForge sells.
How to Choose the Right Brush Cutter?
- Look at the ground. Level bunds and short sessions suit the side pack; steep slopes, terraces and broken ground suit the backpack.
- Name the growth. Mostly grass means the nylon head; hard perennial weed or woody bush means the blade.
- Think about who carries it. Note the heights of the people who will wear the harness and how long each session lasts.
- Count the hours. A few hours a week is light work for either model; long clearing days are easier with the weight on both shoulders.
- Get the safety kit ready: goggles or face screen, ear protection, gloves, leg guards and safety boots.
For example, a vegetable farmer trimming flat bunds twice a month is well served by the 31 cc side pack. An estate worker clearing grass on a hillside every day will be less tired with the GX35 backpack. A mango orchard with thick weed under the trees needs the metal blade on either model.
Common Mistakes to Avoid
Pushing the head into stems it cannot cut. It stalls the engine and, on the backpack model, breaks the flexible shaft. Cut thick stems with a saw.
Using it as a lawn mower. The cut height depends on how it is held, so an even lawn finish is hard to get.
Working without protection. Stones and chips fly from the head; eye, ear and leg protection are needed every time.
Loose harness. A badly adjusted strap tires the operator and makes the head swing unevenly.
Wrong head for the job. A nylon line in woody bush wears away quickly; a blade in soft grass works but clears a narrower strip.
How to Maintain a Brush Cutter?
Every use: check that the blade is tight and undamaged, the guard is fitted and there is no fuel leak. Clean grass and sap off the head and the guard after work.
Air filter: grass dust clogs it quickly. Clean it often during the cutting season and replace it when it is worn; a choked filter makes the engine lose power.
Fuel: use fresh, plain petrol on the 4-stroke models. Do not leave fuel standing in the tank for weeks between seasons.
Blade and line: keep the metal blade sharp and balanced, and replace a cracked blade at once. Re-load nylon line before it runs out mid-job.
Shaft and harness: on the backpack model, look after the flexible shaft and do not bend it sharply. Check harness straps for wear.

Frequently Asked Questions about Brush Cutters
Side pack or backpack brush cutter - which is better?
The side pack is about 2 kg lighter and simpler on level ground. The backpack spreads the weight across both shoulders and is easier on slopes and broken ground.
Does a 4-stroke brush cutter need oil mixed in the petrol?
No. The 31 cc and GX35 type 4-stroke engines run on plain petrol, so there is no mixing in the field.
How wide does a brush cutter cut?
About 255 mm with the metal blade and about 430 mm with the nylon trimmer head on both PackForge models.
Can a brush cutter cut thick branches?
No. Woody stems thicker than the blade can take will stall it. Branches and logs are a job for a chainsaw.
What safety kit is needed with a brush cutter?
Goggles or a face screen, ear protection, gloves, leg guards and safety boots, every time it is used.
What is the price of a brush cutter on PackForge?
The 31 cc side pack is ₹10,250 + ₹1,845 GST and the GX35 backpack ₹11,810 + ₹2,126 GST, with free delivery in India.
