Wheel Accessories

NOTE: All accessory measurements are APPROXIMATE…these items are mostly made in Europe, so original sizes are in Centimeters. We convert them to the closest Inch equivalent.

AXLE EXTENSIONS (sold in pairs)

Available in a variety of lengths to customize the track width of your walk-behind tractor. Sizes range from 5” to 16” total extension (2.5 to 8” per side), plus, we now offer adjustable axle extensions with an 20 inch range of adjustment, variable in 2” overall increments. Use these accessories to increase stability on slopes, or simply to customize the wheel track to a particular application (i.e. Straddling a bed: With the 16” extensions and 10” rim [or larger] wheels, the tractor will straddle a 30” wide bed) NOTE: 20” total (10” per-side) extension is the maximum recommended by the tractor manufacturers. Adding additional extensions beyond 20” will void tractor axle warranty. NOTE: Due to the extra stress/leverage placed on the tractor axle, Axle extensions over 8” are NOT recommended to be used with high-traction-requirement implements such as Subsoilers, Moldboard plows, Root digger plows, Dozer blades, etc.)


NOTE: Sizes listed are TOTAL EXTENSION (both sides combined)…for example: 10” extensions = Qty 2 - 5” extensions, for a TOTAL axle width increase of 10”


4.5” “Factory” Axle Extensions

  • Item 922.43685 (fits BCS) MSRP: $80 $76

  • Item 937112 (fits Grillo) MSRP: $60 $55

Earth Tools “Fixed” Axle Extensions – various sizes

  • Fits BCS & Grillo

  • 8” axle extensions (ET0080) MSRP: $100 $90

  • 10” axle extensions (ET0085) MSRP: $105 $95

  • 12” axle extensions (ET0090) MSRP: $110 $100

  • 16” axle extensions (ET0100) MSRP: $120 $110

NOTE: When axle extensions are mounted, the stress on the lug-nuts and axle hub-nuts on the tractor itself are INCREASED due to the “leverage” of the extension (simple physics – the longer the extensions, the more the leverage and the more stress on the fasteners). It is therefore recommended that the axle-nuts and lug-nuts be checked for tightness at least ONCE per year when 4.5” through 8” extensions are installed, and at least TWICE per year when 12” through 16” axle extensions are installed.


“Earth Tools” Adjustable Axle Extensions – 4” to 20” of total extension - EARTH TOOLS EXCLUSIVE

FINALLY…a set of adjustable axle extensions that has the necessary adjustment range to accommodate both the use of a Rotary Plow in the “narrowest” position, and to be able to easily straddle a 30” bed in the “widest” position. Adjusts quickly with one pin on each side. 1” adjustment increments. Fits BCS 732 - 948, and will fit Grillo G85d - G110 by using a set of spacer flanges (see below). When mounted to tractor, overall width of projecting inner posts is 41”. As an additional feature, if extra weight is needed for additional traction, you can hang 2” center-hole (Olympic-style) barbell-weight plates right on the inner posts!! If you don’t have the extensions adjusted all the way out, just add the weight-plates on the protruding inner post, and put a pin in the end hole to secure them on. You can add up to 80 lbs. per wheel in this mounting position. If you DO have the extensions adjusted all the way out, the weights can be added on the posts INSIDE the wheels…just slide the wheels off the post, slide some weight-plates on, and slide the wheel back on. NOTE: In this case, it is important to keep the weights as close to the wheels as possible, to not strain the axle bearings of the tractor. So slide the weights up against the inside of the wheels, and put an extra pin in the closest hole in the inner post, to keep the weights in that position. MAXIMUM WEIGHT FOR THIS “INSIDE” TYPE OF MOUNTING: 50 LBS. PER WHEEL) NOTE: Due to the extra stress/leverage placed on the tractor axle, it is not recommended that these extensions be extended more than 4” per side [8” total] when used with high-traction-requirement implements such as Subsoilers, Moldboard plows, Root digger plows, Dozer blades, etc.)

  • Earth Tools Adjustable Axle Extensions to fit BCS 732 through 948 and Grillo G131 (NOT BCS 735!) Item ET0110-B, MSRP: $210 $195 (NOTE: BCS 732 requires 2 flat washers on each wheel stud, behind inner “post” mounting plate)
  • Earth Tools Adjustable Axle Extensions to fit Grillo G85d through G110 (NOT Grillo G131!) Item ET0110-G, MSRP: $230 $215 (NOTE: G85d requires 2 flat washers on each wheel stud, behind inner “post” mounting plate)

NOTE: When axle extensions are mounted, the stress on the lug-nuts and axle hub-nuts on the tractor itself are INCREASED due to the “leverage” of the extension (simple physics – the longer the extensions, the more the leverage and the more stress on the fasteners). It is therefore recommended that the axle-nuts and lug-nuts be checked for tightness at least TWICE per year when any “long” axle extensions are installed.


WHEEL WEIGHTS (all units sold in PAIRS)

The pulling or pushing power of a walk-behind tractor is directly related to traction, and a major factor in traction is weight. Wheel weights are the best means of improving traction because they add weight without changing the balance of the machine (because the weight is added right at the “fulcrum” point of the tractor).

By far, our most popular and practical system for adding wheel weights is our “Barbell weight hangers”, which bolt onto the wheel-mounting studs of the tractor (the wheel does not have to be removed to install them; just the lug-nuts) and they accept standard 1” hole barbell weight plates. The weight plates themselves can be removed or installed with a single pin, and since we offer the hangers in various post lengths, you can actually get far more weight on the tractor than with the “factory” weights … 100 lbs max per wheel! The “hangers” can stay on the tractor even when the weight plates are removed…although if you have one of the longer lengths, the posts may stick out and get in the way sometimes…If so, they are easily removed. Video: Demo of these Barbell Wheel Weight Hangers

This is a sweet system, as you do not have to pay shipping charges on the weights themselves…just the mounting “hangers” (posts). You can find new (at any store that sells weight-lifting / sporting goods) or used (at a flea market or yard sale) 1”-center-hole barbell-weight plates in your local area (cast iron are best, to maximize available space in the wheel rims). You might have a set of barbell weight plates sitting in your basement now!!

Barbell weight hangers & weights

  • SHORT (8”) Barbell Weight Hangers Set for BCS Item ETBWBCS-S: MSRP: $55 $50
  • LONG Barbell Weight Hangers Set for BCS (10”) Item ETBWBCS-L: MSRP: $55 $50
  • SHORT (8”) Barbell Weight Hangers Set for Grillo Item ETBWG-S: MSRP: $75 $70

1-inch-center-hole Cast-iron Barbell weight plates can be purchased at any sporting goods store and most department stores…or you can find used ones at a yard sale!

NOTE: Barbell weight hangers cannot be installed in conjunction with Adjustable Axle Extensions!

Also, both BCS and Grillo offer factory cast-iron weights, which are OK IF you don’t mind them being quite hard to take on and off (because the mounting nuts are recessed waaay down in blind holes) AND being horribly expensive…something like $3 per pound for Italian cast iron…

WHEELS & TIRES (sold in PAIRS)

Whether you are needing a second set of wheels to put “duals” on a tractor, a new set of wheels for an old machine, or just want a larger set of wheels for extra ground clearance and/or greater ground-speed, the following is our selection of tire sizes for our walk-behind tractors.

NOTE #1: for a nominal up-charge, most of our new tractors can be fitted with larger-than-standard wheels at the time of purchase. You pay only the difference in the relative cost of the wheels when up-sizing. Make sure you ask us about what wheel size is best for your application. ALSO: Some “larger” wheels may be TOO big for a particular tractor model, due to clearance issues…ask an Earth Tools salesperson for advice.

NOTE #2: “Adjustable track rim” wheels have a separate inner hub and outer rim, which can be assembled in anywhere from 2 to 4 different positions (depending on what the tractor will accommodate), to achieve different wheel widths. To see these measurements, go the Walk-behind tractors page and look at the specs of a tractor that has standard wheels of the size you are interested in.

NOTE #3: If you just need an individual replacement tire or tube for your old rims, these items are considered “spare parts” and we stock all sizes. We do not list these online–Call for prices.

  • 6.5x12x23” Adjustable rim, tractor lug tread (Item 400R.12B.650M4) MSRP: $750 $450
  • 7x12x26” Adjustable rim, tractor lug tread NOTE: In order for this large wheel to clear the muffler on a gas engine, a minimum of a set of 4.5” axle extensions must be mounted, AND the “adjustable rims” of the wheels must be set to the “maximum width” position. With this setup, the wheels will have a spacing of 20” BETWEEN the two tires and a measurement of 34” wide total (if longer axle extensions are used, of course those numbers will increase accordingly) This tire size will also increase the ground-speed of the tractor by 10% over the 6.5x12x23” wheels. (Item TORG 700x12) MSRP: $625 $550
  • Other wheel sizes / types may be available by request…call for details

** These wheels require a minimum of 4.5” axle extensions to mount to some tractors.


FOAM-FILLED TIRE OPTION

On replacement wheels, OR on new tractors, we now offer FOAM-FILLED tires on some of our most popular sizes. Foam-Filling means the tires are filled with Solidified rubber foam, so essentially they become solid rubber wheels once filled.

The advantages of Foam-Filling are:

  • NO FLATS—EVER!!
  • More weight & traction
  • No tire maintenance

The potential disadvantages of foam-filling are:

  • Permanent (not removable) addition of extra weight, and the resulting higher soil compaction.
  • If using the machine on hills, the extra weight means that the tractor requires greater “stopping distance”.
  • The company we use to foam-fill the tires does not always do a “pristine” job in terms of appearance…that is, the tires / rims sometimes get spattered or dripped on with the foam-fill material (dark brown stuff). If the looks of this residue bother you, it does peel off with a bit of effort…

Consider the pros & cons carefully…(If you are unsure about this, this is an option you could always have added at a local tire shop in the future, if desired.)

Prices: (These reflect ADDITION to normal tire cost, if purchasing a new tire set)
  • 5x10x20 (adds 50 lbs. of weight per pair) : add $140
  • 5x12x22 (adds 80 lbs. of weight per pair) : add $160
  • 6.5x12x23 (adds 90 lbs. of weight per pair) : add $175

STEEL WHEELS FOR GARDEN / FIELD WORK (Soil-working / Rear-PTO implements)

Highslide JS

Steel Cage Wheels

These steel wheels provide extra traction for various soil-working applications, and also satisfy the need for some customers of the Plain Faiths who do not use equipment with air-filled wheels. *(And, for ANY user, it’s sometimes nice to have wheels that never go flat!)* The “Cage” type design with 1” deep cleats are great for soilworking applications that require extra traction. Most sizes can be “dualled” by adding the “outriggers” listed below; this doubles the width of the surface area contacting the soil, and “completes” the “Chevron” on each side.

  • 17” diameter, 4” wide Steel Cage Wheels (Item 922.57779) MSRP: $315 $299
  • 19” diameter, 4” wide Steel Cage Wheels (MARTE 420-35-100 ST-WH) MSRP: $300 $270
  • 19” diameter, 4” wide Steel Cage Outriggers (makes 19” steel wheels into “duals”) (ONLY applicable to tractors with differential AND steering brakes!) (MARTE 420-35-100 ST-OUT) MSRP: $180 $150
  • 20.5 diameter, 4.5” wide Steel Cage Wheels (Item MARTE 470-35-120 ST-WH) MSRP: $315 $285
  • 20.5” diameter, 4.5” wide Steel Cage Outriggers (makes 20.5” steel wheels into “duals”) (ONLY applicable to tractors with differential AND steering brakes!) (Item MARTE 470-35-120 ST-OUT) MSRP: $190 $170
  • 22” diameter, 5” wide Steel Cage Wheels (Item MARTE 510-35-130 ST-WH) MSRP: $360 $330
  • 22” diameter, 5” wide Steel Cage Outriggers (makes 22” steel wheels into “duals”) (ONLY applicable to tractors with differential AND steering brakes!) (Item MARTE 510-35-120 ST-OUT) MSRP: $220 $195
  • 26” diameter, 5” wide Steel Cage Wheels (Item MARTE 610-35-120 ST-WH) NOTE: In order for this large wheel to clear the muffler on a gas engine, at least 12” axle extensions must be mounted. This wheel size will also increase the ground-speed of the tractor by 10% over the 22” wheels. MSRP: $430 $400

NOTE REGARDING THE ABOVE STEEL WHEELS: Unlike many of our rubber-tired wheels, the steel wheels above do NOT have adjustable-track-width rims…instead, the rims are “fixed”. So in order to increase track width (for example, to be able to operate a Rotary Plow), our Axle Extensions (above) would need to be used.


STEEL WHEELS FOR HILLSIDE WORK (Mowing / front-PTO implements)

Highslide JS

Spiked wheels

Highslide JS

Super-Bite Outriggers

These Steel-Wheel options are designed for users working on steep hillsides with mowing, hay-making, or transport implements.

The Spiked Wheels provide the ultimate in traction, but as you can expect, are quite a rough ride if you have to transport the tractor over paved or gravel roads at all.


The Super-Bite Outriggers are designed to attach OUTSIDE of an existing pair of rubber wheels, and once the mounting bracket is in place for them, they attach and detach in a few seconds if needed (which gets you back to smooth-riding rubber wheels on hard surfaces). NOTE: Super-Bite Outriggers will require axle extensions to mount properly…see the below video for instructions on figuring out what length axle extensions you will need for your tractor:

CLICK HERE for a video showing the Super-Bite Wheel Outriggers

  • 20.5” Diameter x 14.5” wide SPIKED wheels with 2” spikes (ONLY fits tractors with differential AND steering brakes!) (Item MARTE SPIKE 420x370) MSRP: $799 $750
  • 20” Steel Cage “Super Bite outriggers” - used alongside (outside) 5x10x20 rubber wheels for steep slopes…Mounts with rims of 5x10 wheels set in “standard width” position (ONLY fits tractors with differential AND steering brakes!) (Item MARTE ANTI-DRIFT 570) MSRP: $300 $280
  • 22” Steel Cage “Super Bite outriggers” - used alongside (outside) 5x12x22” rubber wheels for steep slopes…Mounts with rims of 5x12 wheels set in “standard width” position (ONLY fits tractors with differential AND steering brakes!) (Item MARTE ANTI-DRIFT 600) MSRP: $350 $330
  • 23” Steel Cage “Super Bite outriggers” - used alongside (outside) 6.5x12x23” rubber wheels for steep slopes…Mounts with rims of 6.5x13 wheels set in “standard width” position (ONLY fits tractors with differential AND steering brakes!) (Item MARTE ANTI-DRIFT 630) MSRP: $390 $360

TIRE CHAINS

For extra traction in snow & ice, we offer tire chains with 2-link cross chain spacing for the following tire sizes (chains for 10” & 12” tires INCLUDE a set of spring-loaded tensioners):

  • 4x8x16” (Item 1301L) MSRP: $79 $70
  • 4X10X18” (Item 922.SC410) $125 $118
  • 5x10x20” (Item 53131MOD) MSRP: $135 $130
  • 5x12x22” & 6.5x12x23” (Item 53131) MSRP: $150 $130

NOTE: The tire chain manufacturer sometimes gives “extra” chain…don’t know why they do this, but I guess they figure they’d rather err on the side of giving too much rather than not enough. So, if your chains seem “too long” and overlap too much when you wrap them around your wheel, feel free to just cut off the excess, by cutting one link on each side with a small bolt cutter, hacksaw or grinder. (Make sure to cut the “blank” end of the chain, not the end with the clamps on it!!)

TRACKS

We now offer Rubber and Steel Track options for our walk-behind tractors, for the ultimate in traction while maintaining a low ground-pressure to minimize compaction. The tracks we offer are built in Italy, specifically for walk-behind tractors…they are not made for some other application and just “adapted” to walk-behind tractors.

Application/Pricing information

Steel Tracks—Left in above picture/top picture on Right: Best suited for soil-working applications, such as plows, subsoilers, dozer/scraper blade (when working in dirt), root digger, etc. Can be used for mowing as well, but you will tear up some grass whenever you turn the machine, like a steel-tracked bulldozer! Tracks are 7” wide each, and total track width can be adjusted in 7 different positions ranging from 28.5 to 44” outside width. This track type reduces the speed of the tractor by about half, and increases the axle-torque by twice.

  • Item # AGRIZ TRACKS STD STEEL: MSRP: $1999 $1800
  • REQUIRES BRACE-BAR FOR APPROPRIATE TRACTOR:
  • Item # AGRIZ BRACE-BAR BCS (for BCS 749, 750, 852, 853, can be fit to Grillo G131) MSRP: $125 $120
  • Item # AGRIZ BRACE-BAR BCS 779 (for BCS 770 & 779) MSRP: $125 $120
  • Item # AGRIZ BRACE-BAR GRILLO (for Grillo G107 & G110) MSRP: $125 $120
  • IF MOUNTING TO GRILLO G107 OR G110, ALSO REQUIRES SPACER PLATE SET: ET 0115 $20

Rubber Tracks (Reduction version)—Center in above picture/middle picture on Right: This type can be used for limited soil-working applications, but is much easier on grass when mowing…the rubber is more forgiving (not tearing up sod) and a “softer ride”. Also good for gravel grading & snow removal. Tracks are 6.25” wide each, and total track width can be adjusted in 7 different positions ranging from 28.5 to 42” outside width. This track type also reduces the speed of the tractor by about half, and increases the axle-torque by twice.

  • Item # AGRIZ TRACKS STD RUBBER: MSRP: $1899 $1750
  • REQUIRES BRACE-BAR FOR APPROPRIATE TRACTOR:
  • Item # AGRIZ BRACE-BAR BCS (for BCS 749, 750, 852, 853, can be fit to Grillo G131) MSRP: $125 $120
  • Item # AGRIZ BRACE-BAR BCS 779 (for BCS 770 & 779) MSRP: $125 $120
  • Item # AGRIZ BRACE-BAR GRILLO (for Grillo G107 & G110) MSRP: $125 $120
  • IF MOUNTING TO GRILLO G107 OR G110, ALSO REQUIRES SPACER PLATE SET: ET 0115 $20

Rubber Tracks (High-speed version)—Right in above picture/bottom picture on Right: This model only reduces ground speed by 10 to 20% (depending on standard tire size you compare it to), so you can mow at relatively high speeds while having excellent traction and low ground PSI for swampy areas, etc. Tracks are 6.25” wide each, and total track width can be adjusted in 7 different positions ranging from 27.5 to 40” outside width. Also available (by special order) with 2”-long hardened-steel “STUDS” for super traction on steep slopes

  • IF MOUNTING TO GRILLO G107 OR G110, ALSO REQUIRES SPACER PLATE SET: ET 0115 $20

AVAILABLE TO FIT CURRENT BCS MODELS 749, 750, 779, 852 AND 853, GRILLO MODELS G107, G110 & G131, and also OLDER BCS and Grillo tractors that are equipped with Differential Axle and Independent Steering Brakes (brace-bars may need to be modified to fit). Can also be Special-ordered to fit BCS 660 Hydro (track versions differ slightly for this model).
NOTE #1: Total track widths will vary from above on BCS 750 [add 4”] and Grillo G131 [add 3”])
NOTE #2: The “brace-bar” mounts to the tractor at the TOW HITCH, so you cannot pull a trailer from the standard tow hitch while tracks are mounted. HOWEVER, you can add a “Drawbar” to the tractor PTO mount, to pull a trailer from this point. Ask an Earth Tools salesperson for details.
