HEINPRO Mower and Trimmer Listings Compared by Battery, Width and Weight

As an Amazon Associate we earn from qualifying purchases. Details

Shoppers searching for a heinpro mower want to know which HEINPRO yard tool fits their lawn and the battery they already own. The research pool holds ten HEINPRO listings, and only one of them is a mower: a 14-inch walk-behind for DeWalt 20V MAX batteries. The other nine are string trimmers, hedge trimmers and a leaf blower. They stay in this roundup because mowers, trimmers, edgers, blowers and chainsaws are the product types this topic keeps. Every listing says the battery and charger are not included, so the battery platform sets the real cost. This page sets out what each listing states, where its title, bullets and specification fields disagree, and what none of them tells you.

Quick answer

• Start with the battery you already own. The ten listings name three platforms: DeWalt 20V MAX on six listings, Milwaukee M18 on three, and Makita 18V on one.
• The mower is the only walk-behind in the set. Its listing gives a 14-inch cutting width, five height positions from 1 to 2.6 inches, and a weight of 17.8 pounds.
• For edging, the 12-inch heads with a wheeled-edger mode are the closest match. For hedges, the three 22-inch trimmers share a listed weight of 4.4 pounds and a 5/8-inch cut capacity.
• Runtime and warranty figures in these listings are the maker’s own claims. The references we opened do not confirm any of them.

What this set covers

The HEINPRO research record holds ten listings, and all ten are types this topic keeps: one walk-behind mower, four string trimmers (several bullets call them weed wackers or weed eaters), four hedge trimmers, and one leaf blower. None was dropped for type, and no product was added to fill a gap.

Battery platform named in the listing	Mower	String trimmer	Hedge trimmer	Leaf blower	Total
DeWalt 20V MAX	1	2	3	0	6
Milwaukee M18	0	2	1	0	3
Makita 18V	0	0	0	1	1
Total	1	4	4	1	10

The table groups each listing by the battery family its title or bullets name. Those are the seller’s compatibility statements, not confirmations from a battery maker, so check the battery family before you buy. If you already own one platform, start with its rows, which is why the platform column comes first.

The mower: a 14-inch deck and a 1 to 2.6 inch range

The only mower is the DeWalt-compatible walk-behind. Its specification fields give a 14-inch cutting width, a product size of 44.5 by 15.2 by 41.1 inches, and a weight of 17.8 pounds. The bullets add a mulch plug and a 9.25-gallon bag, which the listing gives as 35 liters.

The deck is 14 inches wide, against 12 inches for three of the four trimmer heads in this roundup. Dividing gives 14 divided by 12 = 1.17, so the deck is about 1.17 times as wide. That is a width comparison only. The bullets give a coverage claim of roughly 1,200 to 1,500 square feet on one battery, and they add that actual coverage depends on lawn density, terrain and cutting height. Treat that figure as the maker’s estimate.

The listing names a 1-inch minimum and a 2.6-inch maximum across five positions, but it does not say how the five steps are spaced. If the steps are even, 2.6 minus 1 = 1.6 inches of range, and 1.6 divided by 4 = 0.4 inch per step. That puts the positions at 1.0, 1.4, 1.8, 2.2 and 2.6 inches. The spacing is our arithmetic, not a listed figure.

Illinois Extension suggests a mowing height of about 2½ to 3 inches for most home lawns, and it notes that some other state university recommendations go as high as 4 inches. The mower’s top setting, 2.6 inches, sits at the low end of that suggested range, and nothing in the listing reaches 3 inches. The same page advises removing no more than one third of the grass blade in a single cut. On a lawn 4 inches tall, the one-third limit is 4 divided by 3 = 1.33 inches, so the cut should stop at 4 minus 1.33 = 2.67 inches. The top setting of 2.6 inches removes 4 minus 2.6 = 1.4 inches, which is more than that limit. A lawn grown that tall cannot be brought within the rule in one pass at this mower’s top setting, because the rule calls for 2.67 inches, a height the mower does not offer.

Mower safety is a separate question. UF/IFAS notes that thousands of people each year are treated for lawn mower injuries, and that most of those treated are children and older adults. Its advice is to keep children out of the yard while mowing. The Ohio State extension page says an electric mower should never be used on wet grass, and the Illinois page makes the same point about wet grass. Both are reasons to wait for a dry lawn before mowing.

The string trimmers: 12-inch heads, one 16-inch head, two feed styles

Four listings are string trimmers. Three are 12-inch heads and one is a 16-inch head. The table below gathers what each listing states.

Listing	Battery platform	Cutting width	Weight	Feed (as the bullets describe it)	Speed or motor
12-inch string trimmer, M18	Milwaukee M18	12 in	3.7 lb	About 0.4 in on start, plus manual release	8500 rpm
12-inch string trimmer and edger, DeWalt	DeWalt 20V MAX	12 in	4.2 lb	About 0.5 in per trigger press, plus manual	Not listed
12-inch string trimmer and edger, M18	Milwaukee M18	12 in	4.2 lb	About 0.5 in per trigger press, plus manual	Not listed
16-inch weed wacker, brushless	DeWalt 20V MAX	16 in	Not listed	Bump feed	6000 rpm brushless

The 16-inch head covers 16 divided by 12 = 1.33 times the width of a 12-inch head per pass. Its listing gives a brushless motor, a 6000 rpm rating and a 0.08 inch line. Our research record for it holds short notes rather than the full bullet text, so its handle, weight and feed details are thinner than for the other three.

Feed style matters for safety as well as convenience. The Virginia Tech lawn care guide warns that automatic-feed and bump-feed trimmers may release more string than needed, and that this raises the chance of striking the operator. Check the string length often on any of these heads, whichever feed style it uses.

The two 12-inch edger heads, one DeWalt and one M18, carry the same bullet text. Their bullets say the cutting head rotates 90 degrees to work as a wheeled edger, and that the handle turns 180 degrees with five cutting angles. The M18 head with 8500 rpm also describes an in-line wheeled edger mode, so the edging function is not unique to the DeWalt listing.

The line details differ between the M18 listings. The 3.7 pound head lists a 0.065 inch line, while the 4.2 pound M18 edger lists 0.055 inch spools. That is a gap of 0.065 minus 0.055 = 0.01 inch. The lighter head is 4.2 minus 3.7 = 0.5 pound lighter than the edger, so the choice between them is a trade between line diameter and the edging function.

The hedge trimmers: an 8.7-inch head and three 22-inch models

Four listings are hedge trimmers. One carries an 8.7-inch blade and two grass shear blades, and three carry 22-inch blades.

Listing	Battery platform	Blade length	Weight	Other detail the listing gives
Two-blade trimmer and grass shear	DeWalt 20V MAX	8.7 in	1.8 lb	Hedge and grass shear blades; run times of up to 120 min (short blade) and 80 min (long blade)
22-inch hedge trimmer, black	DeWalt 20V MAX	22 in	4.4 lb	5/8-inch cut capacity; 180-degree rear handle
22-inch hedge trimmer, yellow	DeWalt 20V MAX	22 in	4.4 lb	Same bullet text as the black model
22-inch hedge trimmer, M18	Milwaukee M18	22 in	4.4 lb	Speed field 2700 rpm; high carbon steel blade

The 22-inch blades are 22 minus 8.7 = 13.3 inches longer than the 8.7-inch blade. The 22-inch models also weigh 4.4 minus 1.8 = 2.6 pounds more. Those two numbers are the main trade-off in this group: reach and cutting area on one side, a lighter tool on the other.

The 22-inch models have a specification field reading 0.63 inches under cutting width. The bullets explain that figure as the 5/8-inch cut capacity, which is a branch thickness, not a blade size. Read the blade-length field for the blade, and the bullets for the capacity.

The Virginia Tech guide describes the two-hand hold as a safety feature of powered hedge trimmers, and it says never to run an electric hedge trimmer overhead. Its advice is to check all safety features before each use. The guide also says to disconnect power before trying to clear a lodged blade. These are general rules for powered trimmers, and they apply to these cordless models as well. The listing for the 8.7-inch head claims a blade guard, a safety locking device and a soft start. Those are the maker’s claims. For a separate comparison of cordless hedge trimmers, see our Stihl HSA 45 cordless hedge trimmer roundup.

The leaf blower: one Makita-compatible model

The blower’s title and bullets name Makita 18V compatibility. Its listing gives 500 cfm of air volume and a maximum speed of 150 miles per hour, with five speed modes and a rubber-wrapped handle. Its weight is 4.3 pounds.

The Virginia Tech guide describes hand-held electric blowers as usually weighing about 7 pounds or less. The blower’s 4.3 pounds sits inside that range, with 7 minus 4.3 = 2.7 pounds to spare. The same guide puts a 100-foot working limit on electric blowers, which describes corded models. This blower is cordless, so the limit does not apply, but its run time becomes the working limit. The listing gives no run time for it. For a related blower comparison, see our DeWalt 20V MAX brushless handheld blower roundup.

Batteries and charging: what the listings leave out

All ten listings say the battery and charger are not included. The platform named in each listing decides which battery you need, and batteries do not move freely from one platform to another, so match the platform before you buy anything else.

Run-time figures in these listings need the battery size. The mower’s bullets give a 15 to 20 minute runtime on one 4.0 Ah DeWalt battery. The 8.7-inch trimmer’s run times name a DeWalt 20V 2.0 Ah battery. Neither figure is independent. For how used batteries should be handled and recycled, the US EPA says to tape the terminals or keep each lithium-ion battery in its own plastic bag. It also says used batteries can still hold enough energy to injure or start a fire, and that a damaged battery should be handled according to the maker’s instructions. For a related battery guide, see our lawn mower battery voltage and amps guide.

Electric safety in practice

The Virginia Tech guide’s cord checks apply to corded tools, and none of the HEINPRO listings is corded. The guide’s other rules still apply: check the safety features before use, hold a powered trimmer with both hands, do not run a hedge trimmer overhead, and disconnect power before inspection or repair. The Ohio State extension page says to disconnect the electric plug before repairing a mower. For a battery mower, removing the battery where the design allows is the equivalent step; that is our reading, not a listed instruction.

How we chose

• Scope: the HEINPRO listings in the research record, ten in all. Each one is a mower, trimmer, edger, blower or chainsaw type, and the hedge trimmers and string trimmers count as trimmers.
• Source material: the listing’s title, bullets and specification fields, used as written. Where they disagree, we follow the bullets and say so in the text.
• Order: by battery platform, then by tool type, so each battery family stays in one place.
• Left out: prices, ratings and sales figures. The research record holds none of them, and this roundup does not use them.
• Safety points come only from the extension and EPA pages listed in the references, and each one is a general rule for the tool type, not a claim about HEINPRO’s own design.

The ten listings, one by one

What we could not verify

• Runtimes and coverage figures are the listings’ own claims. The references we opened do not measure HEINPRO run time or mowing coverage.
• The one-year warranty comes from one specification field. We did not check it against a HEINPRO warranty document.
• Compatibility statements come from the listings. We did not check any of them against battery makers’ documents.
• The 16-inch head’s research record holds short notes, so its handle, weight and feed details are thin.
• Two listings disagree on line diameter (0.065 inch against 0.055 inch) and on automatic feed (about 0.4 inch against about 0.5 inch). The listings do not say which applies to a given spool.
• The five mower height steps are not stated. The even spacing is our arithmetic, and the listing may space them differently.
• The black and yellow 22-inch DeWalt-compatible trimmers carry the same bullet text, and the listings do not explain why.

FAQ

Does any HEINPRO listing include a battery or charger?

No. Buy the battery for the platform named in the listing, or confirm that you already own one.

Which listing is the mower, and what height range does it cut to?

The only mower is the 14-inch walk-behind for DeWalt 20V MAX batteries. Its listing gives a 1-inch minimum and a 2.6-inch maximum across five positions. Illinois Extension suggests about 2½ to 3 inches for most home lawns, so the top setting sits at the low end of that range.

Can I use a HEINPRO trimmer with a battery from another brand?

Only if the listing names your platform. Each listing names one battery family: DeWalt 20V MAX, Milwaukee M18, or Makita 18V. Compatibility is the seller’s statement in the listing, so check the battery family against the listing before you buy.

Are the black and yellow 22-inch hedge trimmers different tools?

Their bullets, blade length and listed weight are the same. The listed product length differs by half an inch (38 minus 37.5 = 0.5 inch), and the colors differ. The listing does not say what else separates them, so the listing alone does not show two different models.

What should I check before using a battery hedge trimmer?

Check the safety features before each use, as the Virginia Tech guide advises. Hold the trimmer with both hands, do not run it overhead, and disconnect power before clearing a lodged blade. Store and recycle the battery as the EPA page describes, with the terminals taped and the battery kept separate.

Bottom line

Pick the battery platform first, then the tool that fits the job the listing describes. The one mower suits a DeWalt 20V MAX owner whose grass stays inside the 1 to 2.6 inch range. A lawn grown to 4 inches cannot be brought within the one-third rule at this mower’s top setting in one pass, so plan the cut height before you buy.
